In partnership with the NYC Department of Parks & Recreation, the 2012 Land Art Generator Initiative (LAGI) ideas competition asks landscape architects, architects, planners, artists, and engineers to submit proposals for a 100-acre “pragmatic art installation” in Freshkills Park, Staten Island, New York City that can generate power from renewable energy sources.

According to Freshkills Park, the park will total 2,200 acres when completed, making it almost three times the size of Central Park. In an amazing transformation of what was formerly the world’s largest landfill, a decrepit garbage dump of a landscape may become a “symbol of renewal and an expression of how our society can restore balance.” Designed by James Corner Field Operations, the park will provide hundreds of acres of recreational opportunities. A full-scale ecological restoration by ecologist Steven Handel is also underway, which will underpin the environmental education programs.

LAGI’s idea competition, like the one held in 2010 in Abu Dhabi, is designed to unleash wildly creative thinking about how renewable energy can be made beautiful. The idea this year is to design a public artwork for Freshkills that will not only have “conceptual beauty” but can also harness energy from nature and convert it into electricity. The group’s organizers emphasize that they don’t want a timid public art work, but instead seek to leverage the “expansiveness” of Freshkills to create a massive 100-acre art project that can power thousands of nearby homes from Freshkills’ East or North parks. 

Specifically, entries must include a “three-dimensional sculptural form” that can inspire visitors to think deeply about “broad ideas as ecological systems, human habitation and development, energy and resource generation and consumption,” but can also sit within the historical and ecological context of the site. The artwork must capture energy from nature (in the form of wind, solar or solar thermal, or another renewable energy mechanism), convert it into electricity, and be capable to transmitting energy via a power grid connection point. “Consideration should be made for artfully housing the required transformer and electrical equipment within the project boundary.”

Entries cannot have negative environmental impacts on the park or release greenhouse gas emissions. Each submittal must then include a brief environmental impact assessment. Given the park rests on top of a landfill cap, the designers will also need to discuss how the project will fit in with those carefully engineered systems. “The cap shall not be penetrated in any manner for any reason.” 

Furthermore, LAGI asks teams to use scalable and tested technologies. “It is recommended that the design team make an effort to engage the manufacturers of existing technology in preliminary dialogue as a part of their own research and development of the design entry.”

Submit your concepts before July 1, 2012. The jury considering the entries includes top designers like James Corner, ASLA, and Bjarke Ingels, as well as senior officials from Staten Island, the NYC Departments of Sanitation and Parks & Recreation, the NYC Public Art Commission, and U.S. Department of Energy.

Winners will take home $20,000 in award money. LAGI writes that the award will not guarantee a construction commission, but the “most pragmatic and aesthetic” designs will be promoted to local NYC stakeholders. Separately, a competition for high school students interested in how to power NYC with art will be open at the same time, with $1,000 up for grabs.

Last year, we only have five top books (see earlier post), but this year we’ve expanded the list. A range of great books came past our desk and any of these may be of interest to your favorite landscape architect. Here are the top ten books of 2011, along with five other notable books:

Landscapes in Landscapes by Piet Oudolf (Monacelli Press, 2011)
In his complex, endlessly interesting landscapes, Oudolf says he prizes form and texture as much as color. He almost exclusively uses perennials, which he values for their “beauty throughout their natural life cycle.” Requiring little maintenance, his naturally sustainable landscapes, which feature drought-resistant plants, evolve over time. As Charles Waldheim, chair of the landscape architecture department at Harvard University Graduate School of Design (GSD), wrote in The New York Times, “he’s gotten away from the soft pornography of the flower. He’s interested in the life cycle, how plant material ages over the course of a year.” Read the full review.

The Altered Landscape: Photographs of a Changing Environment by Ann M. Wolfe (Editor) (Skira Rizzoli, 2011) 
From the book: “This comprehensive look at the work of 100 contemporary photographers captures the impact of human activity on natural landscapes. The Altered Landscape is a provocative collection of photographs representing a wide range of artists, techniques, visual styles, subjects, and ideological positions. Organized chronologically, the more than 150 images-by artists such as Andy Goldsworthy, Chris Jordan, Catherine Opie, and Edward Burtynsky-reveal the ways that individuals and industries have marked, mined, toured, tested, developed, occupied, and exploited landscapes over the last fifty years.”

Field Notes from Science and Nature by Michael R. Canfield  (Editor), Edward O. Wilson (Foreword) (Harvard University Press, 2011)
The Los Angeles Times writes: “This gorgeous book reproduces samples from the notebooks of 12 naturalists in all their glory, accompanied by short essays on methodology and why field notes are still so critical to the art of science. These drawings, notes (in spectacular handwriting), photos, and maps are a reminder that natural history is the root of all biology, and observation is a critical skill. George Schaller’s drawings of a lion hunt in the Serengeti, Bernd Heinrich’s delicate drawings of leaves, Kenn Kaufman’s lists, Jonathan Kingdon’s drawings of acacia trees in Kenya, Jenny Keller’s spectacular drawings of moon jellies–these and others make science look not only appealing, fascinating and fun but human and creative as well.

Genius of Life: The Life of Frederick Law Olmsted by Justin Martin (Da Capo Press, 2011)
Genius of Place: the Life of Frederick Law Olmsted, a new biography by Justin Martin, illuminates Olmsted’s major achievements as a visionary artist, social reformer, pioneering environmentalist, and founder of the modern profession of landscape architecture. Olmsted is best known for creating several noteworthy landscapes, including New York City’s Central Park. Martin, a journalist who has written two acclaimed biographies on Alan Greenspan and Ralph Nader, paints a portrait of Olmsted as a preeminent American figure, revealing that “as a park maker, environmentalist, and abolitionist, Olmsted helped shape modern America.” Read the full review.

High Line: The Inside Story of New York City’s Park in the Sky by Joshua David and Robert Hammond (Farrar, Straus, Giroux, 2011)
The New York Times writes: “This lushly illustrated volume showcases the range of imaginative designs [Joshua David and Robert Hammond] explored and, in some cases, rejected. In recounting their decade-long experiment, they provide an inspiring primer for grass-roots urban planning.” Paul Goldberger at The New Yorker writes: “In this book Robert Hammond and Joshua David, who led the grass-roots movement to rescue the High Line from demolition, tell with energy, passion, and refreshing candor the story of how this industrial artifact became, against all odds, a magnificent park.” 

Making Healthy Places: Designing and Building for Health, Well-being, and Sustainability by Andrew Dannenberg (Editor), Howard Frumkin (Editor), and Richard Jackson (Editor) (Island Press, 2011)
Dr. Richard Jackson (see earlier post) and Dr. Howard Frumkin (see earlier post) have been long-time advocates of marrying public health and design. In this book, they offer a how-to that is essential reading for all landscape architects. “The authors have crafted an exemplary look at the various components of community design that promote and support health. Through their perspective we see clearly how much community design matters to our health and well-being; and it matters a lot.” – Georges C. Benjamin, MD, Executive Director, American Public Health Association. Read the full review.

MAPS by Paula Scher (Princeton Architectural Press, 2011)
Map making is not just about creating visual representations of physical spaces, but can also be about documenting impressions and emotions. Paula Scher, a partner at Pentagram and one of the most influential graphic designers of her generation, has a new book that conveys the rich, complex feelings she has for the process of map making itself. As she writes in the introduction, “I began painting maps to invent my own complicated narrative about the way I see and feel about the world. I wanted to list what I know about a place from memory, from impressions, from media, and from general information overload. They are paintings of distortions.” Read the full review.

The New American Landscape: Leading Voices on the Future of Sustainable Gardening by Thomas Christopher (Editor) (Timber Press, 2011)
Instead of exacerbating environmental issues, gardeners must harness the many ecosystem services provided by natural systems and design gardens that support and strengthen local ecologies. This how-to guide clearly demonstrates how gardeners’ sustainable practices can positively shape our shared enviroment. Read the full review.

Triumph of the City: How Our Greatest Invention Makes Us Richer, Smarter, Greener, Healthier, and Happier by Edward L. Glaeser (Penguin Press, 2011)
“Edward Glaeser is one of the world’s most brilliant economists, and Triumph of the City is a masterpiece. Seamlessly combining economics and history, he explains why cities are ‘our species’ greatest invention.’ This beautifully written book makes clear how cities have not only survived but thrived, even as modern technology has seemingly made one’s physical location less important.” - Steven D. Levitt, co-author of Freakonomics and SuperFreakonomics, professor of economics at the University of Chicago.

The View from Lazy Point: A Natural Year in an Unnatural World by Carl Safina (Henry Holt & Co, 2011)
From the Booklist review: “From his home base, this celebrated scientist and activist travels to places where the impact of climate change and environmental abuse is starkly evident. With the spiral of a year as his structure and with what Einstein termed the ‘circle of compassion’ as his moral compass, MacArthur and Guggenheim fellow Safina illuminates the wondrous intricacy and interconnectedness of life in a book of beautifully modulated patterns and gracefully stated imperatives.”

At The Atlantic Magazine‘s Green Intelligence forum, which has become an annual event in Washington, D.C., Carol Browner, who was very recently climate change “czarina” at the White House and once head of the Environmental Protection Agency (E.P.A.); Jim Connaughton, Constellation Energy, and former head of the Council for Environmental Quality under President George W. Bush; David Hawkins, Natural Resources Defense Council; and Dave McCurdy, American Gas Association, all emphasized the need for a national renewable energy standard given no big climate change and energy legislation will be coming out of Congress in the next 18 months to 2 years. A new national standard, many said, could also help achieve many of the goals of the failed 2010 climate change and energy legislation. As Senator Amy Klobuchar noted in an earlier speech that day, Minnesota’s “aggressive” renewable energy standard (25 percent renewable energy by 2025) had led to skyrocketing growth in wind, solar, and biofuels in her state.

No Big Climate Change Legislation Coming Soon

Asked by Ed Luce, The Financial Times, how the debate in Washington could get steered back to climate change, the panelists punted a bit. Browner said “we could pass legislation, but not large legislation anytime soon.” She said there’s a set of tools available to the administration, including new rules and standards, which are now being used to ensure cars hit 54 mpg by 2015. Browner noted that 65 percent of total emissions in the U.S. can be dealt with through existing laws, regulations, and administrative tools.

For Connaughton, who is said to be Mitt Romney’s choice as the head of the E.P.A., there are already “six different types of regulatory programs” in the U.S., including the mandatory cap and trade program approved in California. Also, at the Federal level, the House and the most recent administrations, through their many attempts to pass major climate change legislation, have already laid an important “foundation.” This solid base has led to “10 billion tons in carbon reductions.” He said the foundation is now in place for moving many smaller pieces of legislation, like a national renewable energy standard, that would help with the climate.

NRDC’s David Hawkins thought the big climate change legislative failure in 2010 was due to the economy, the slogan that got associated with climate change – it’s “a jobs-killing energy tax,” and the growing belief that “this is not a problem that needs to be addressed.” He thinks these issues are just a “dam and not a permanent fixture in the U.S. political economy,” meaning all these obstacles can be overcome.   

According to Dave McCurdy, American Gas Association, which has been promoting fuel efficiency, there are “more opportunities on efficiency,” including fuel economy standards. He wants smarter incentives that can push firms to work with state governments and environmental groups, and said there needs to be a stronger emphasis on state action.

What Does Solyndra’s Failure Mean?

Will the failure of Solyndra, a major U.S. solar panel producer, which received nearly half a billion in recovery funds, do permanent damage to the case for investing in clean energy in the U.S.?, asked Luce. Browner said the U.S. has been making investments in energy and technology for more than 100 years, including long-term investments in the oil industry and nuclear power. “If we want a different future, we need to use the appropriate incentives.” She added that 100 years of pro-oil tax policies “have been enough.” Incentives, in the form of a national renewable energy standard, could lead to “huge investments” in cleaner energy. Connaughton basically argued that Solyndra was an “unfortunate, sad lesson” but it doesn’t change the overall program of government investment in clean energy.

For Hawkins, the government played its role. “Governments don’t give loan guarantees to companies that have no risk. If there was less risk, the private sector would do it.” He said Solyndra, which set its business model on rising prices for solar panels, was the “victim of progress in the solar industry.” Prices came down dramatically, which is good for the solar industry and consumers, but “bad for them.” McCurdy thought it was the “dynamic of the stimulus funds,” which had to “push lots of money out the door fast.” The result: some projects “fail, spectacularly.”

What Can Happen in the Near Term?

Connaughton says Congress was already questioning the value of big investments in clean energy before Solyndra failed. He wants mandates that are “performance-based,” meaning incentives that can enable the market’s competitive forces to do their stuff.

“Waxman-Markey (the 2010 comprehensive climate change and energy legislation) got too big, there were too many add-ons.” Interestingly, he added that cap and trade was “originally a Republican idea,” but in this instance got swamped by excessive add-ons so the legislation lost its shape. He sees “phased-in standards” organized by sector as the way to go, then a process of “national simplication” to align the sector standards into a bigger picture.

He used a range of examples to show how “market structures have had impact on energy efficiency.” Browner seemed to agree in part, but added that what’s really key is “incentives, investments, and creating demand so the private sector can make the changes needed. “

Hawkins reminded everyone that some Republicans are set on limiting the powers of the E.P.A. to regulate greenhouse gas emissions under the Clean Air Act. “We can’t dismantle these tools that exist” while hoping to make progress through standards and other approaches.

Interestingly, none of the panelists mentioned two of the most important recent stories that should figure in this conversation. The world’s population recently hit 7 billion, which means a complete “rethink of climate approaches” is needed, says National Geographic. According to its Newswatch site, climate change, population, and food production are all deeply linked: “Paul Ehrlich of Stanford University, famous for his book The Population Bomb, said people will have trouble feeding themselves as climate change worsens. But it’s a catch-22, he said, because we need to expand agriculture, but as it’s practiced today, it is also one of the biggest emitters of greenhouse gases.”

Also, according to The Guardian, World Energy Outlook 2011, a recent International Energy Agency (IEA) report, was very negative on the prospect of the global energy system changing enough to effectively combat climate change. The report said that “the world is likely to build so many fossil-fuelled power stations, energy-guzzling factories and inefficient buildings in the next five years that it will become impossible to hold global warming to safe levels, and the last chance of combating dangerous climate change will be ‘lost for ever.’”

Washington, D.C. leadership has requested input from a range of organizations as it develops a new “unified vision” and “comprehensive framework” for a more sustainable Washington, D.C. The end goal: to connect sustainability with economic development and become the number-one, most sustainable city in North America. Washington, D.C. is currently ranked eighth in a recent Economist Intelligence Unit report sponsored by Siemens.

As part of this process, the American Society of Landscape Architects (ASLA) polled members from its Potomac, Northern Virginia, and Southern Maryland chapters and incorporated their input into a set of bold recommendations in the priority areas identified by the city government. Because the categories of recommendations will be evaluated by different D.C. agencies, recommendations are repeated when appropriate and relevant. Among them:

Energy: Reuse brownfields as solar energy farms. Through revised building codes and local tax incentives, expand use of smart tree placement and green roofs and walls. Reduce building energy use through green infrastructure. Incentivize the use of rooftop solar panels. Read research and recommendations >

Climate Change / Mitigation: Reduce total greenhouse gas (GHG) emissions by expanding urban park land, further improving bike and pedestrian infrastructure, incentivizing the growth in the number of bicycle and pedestrian commuters, creating highly walkable pedestrian-only areas, and introducing new innovative forms of public space such as parklets and underpass parks. Read research and recommendations >

Climate Change / Adaptation: Increase coverage of street trees for shade and expand use of green and cool (white) roofs in order to adapt to higher average temperatures along with more varied temperature fluctuations within the District. Improve building and landscape water efficiency measures. Develop resiliency plans for Washington, D.C.’s plant and animal life within parks and green spaces, including the introduction of wildlife migration corridors and heat and drought-tolerant plants. Read research and recommendations >

Water: Develop a comprehensive green infrastructure plan that leverages existing grey infrastructure. Use Sustainable Site Initiative™ (SITES™) guidelines to improve water efficiency measures, require the use of appropriate plant species in public and residential landscapes, and enable rainwater capture and filtered or treated greywater (and even blackwater) reuse for landscape irrigation. For stormwater management, require the use of green roofs for new buildings exceeding a minimum size. In addition, approve the use of rainwater cisterns for irrigation of green roofs and other green infrastructure. Improve the permeability of the District’s park surfaces and their ability to capture and store water. Create multi-use infrastructure, or rain gardens or bio-retention systems in District parks, turning them into green infrastructure and water treatment systems. Increase the use of bioswales near transportation systems, and add in permanent green street corridors and green alleys. Continue to expand urban tree canopy and preserve larger trees to manage stormwater runoff. Spread use of tree boxes and permeable pavements for stormwater capture. As part of a public education campaign, parks and public green space should follow the highest water efficiency standards. Read research and recommendations >

Transportation: Expand bike and pedestrian infrastructure. Create safe bicycle infrastructure. Connect the Metro system with bike infrastructure and bikeshare stations. Require secure bike parking within office and residential buildings. Incentivize the growth in the number of bicycle and pedestrian commuters. Create highly walkable pedestrian-only areas, and introduce new innovative forms of public space such as parklets and underpass parks. Read research and recommendations >

Waste: Set clear, ambitious targets and deadlines for achieving zero waste in the District and measure progress against targets. Ensure all building materials are reused in new buildings (if the materials are non-hazardous). Use Sustainable Sites Initiative (SITES) guidelines for park maintenance and eliminate grounds waste generated from Washington, D.C., parks through composting. Read research and recommendations >

Built Environment: Invest in turning more brownfields into parks. Apply bio-remediation and other safe environmental remediation technologies during park development. Develop an Internet-accessible inventory of all brownfields in the city to enable easier remediation and redevelopment of derelict sites by local developers. Create a certification program for remediated brownfields to facilitate faster reuse. Invest in retrofitting older school buildings to make them LEED Platinum and also integrate green school redesign activities into school curricula. Ensure all schools apply Safe Routes to Schools design guidelines. Read research and recommendations >

Nature: Develop a biodiversity and environmental education action plan based on the concept of biophilia. Recreate wetlands along riverfront edges and reintroduce native wildlife. Reduce the mortality rate of trees and extend their lifespan by enabling them to grow in larger tree pits with structural soils and under permeable pavements. Use appropriate trees grown locally for urban forestry campaigns. Experiment with growing trees in park nurseries. Read research and recommendations >

Food: Develop a comprehensive urban agriculture plan. Evaluate all available empty lots (including brownfield sites) as potential opportunities for commercial and community urban agriculture. Develop new codes enabling local food production. As a priority, target food desert communities with high numbers of brownfields. Allow local residential food production. Develop new soil testing and clean-up requirements for growing food in former brownfield sites. Allow and also increase tax incentives for rooftop food production. Read research and recommendations >

Green Economy: Invest in bicycle and pedestrian infrastructure improvement projects to boost job growth. Use green infrastructure systems, including green roofs, to increase number of local, non-exportable green jobs. Launch a comprehensive green jobs program, training chronically unemployed and former convicts in brownfield remediation, green roof installation, and other tasks. Launch a national campaign in an effort to lure the best green talent to the District. Read research and recommendations >

Governance: Organize watershed councils at the local level and appoint ward-level sustainability advocates to help implement and align SustainableDC initiatives. Use Sustainable Sites Initiative (SITES) guidelines as a management tool for achieving high-performing landscapes across the district. Read research and recommendations >

Neil B. Chambers, founder of Chambers Design, Inc. and Green Ground Zero, is an award-winning green designer with nearly 20 years of experience in the field of green building and infrastructure. He is the author of Urban Green: Architecture for the Future, and a contributing author to Treehugger. He is a national fellow with the Environmental Leadership Program, has taught at New York University and the Fashion Institute of Technology (FIT), and been featured in Architectural Record, Civil Engineering, BBC News, and The Economist.

In your new book, Urban Green: Architecture for the Future, you argue that the number of green building projects in the U.S. (4,000) is abysmally low. Even with an anticipated 30,000 projects in the pipeline, these green buildings are a drop in the bucket and won’t solve our core problems. A far more comprehensive approach is needed if we are going to reduce energy and water use, restore wildlife habitats, and develop sustainable cities over the long-term. What approach is missing and still needed?

We need to revolutionize the entire system of how buildings, real estate, infrastructure, and capital projects are approached, designed and implemented. The green buildings of today are a fair start but not anywhere near what needs to take place in the architecture, engineering, and construction world. We are basically still dealing with water, energy, and buildings the same way we were 150 years ago. I don’t want to come across as anti-green, because I’m not. But the current green building industry is only addressing a small percentage of the problems. In fact, dealing with climate change and energy efficiency is like polishing the silverware as the Titanic sinks. That may sound crazy to anyone within the green building movement.

But the truth is that climate change and many other issues would disappear if we adhered to the ecological principles that govern nature and ecosystems. In my book, I talk extensively about the power of old growth forests, estuaries, and prairies ability to sequester carbon, modulate temperature, manage stormwater, reduce flooding, and purify water better than any technology known to humans. I use specific projects that have re-established habitat and natural lands which provide incredible amounts of clean water, habitat, and better quality of life to people. Everyday there are new inventions that are promising to make our lives better – but if you look at ecological solutions, you’ll find that they outperform every cleantech idea currently in the market. Ecological solutions cost a fraction of what technological solutions cost, and need far less maintenance than the new green gadgets and gizmos being pushed as the great hope for our future.   

You are against electric cars, saying they won’t be great for the environment given they will run on electricity generated from coal, at least in the near term. However, you don’t discuss the fact that car transportation CO2 emissions are some 30 percent of the total. Also, cars create air pollution. On these fronts, isn’t the move to electric vehicles a plus?

Lots of people are in love with EVs, but these new cars are not the answer to any of problems we face. EVs will cause more pollution, more carbon emission and more environmental impact than they solve. This is because of a few factors: the growth of EVs is too dependent on other technologies also growing at the same rate or faster to offset any negative ramifications they may create. These tandem technologies include things such as smart grids, renewable energy production and battery technology. It is unrealistic, and quite frankly misleading, for EV advocates to say these will happen as recommended and hoped. For example, EV advocates expect renewable energy generation to grow fast enough to feed a growing fleet of electric cars in the United States green energy. However, the percentage of U.S. electricity produced by non-hydro renewable energy sources will increase from 4 percent in 2009 to 12.3 percent in 2030, according to the “Annual Energy Outlook 2010″ released by the U.S. Department of Energy’s Energy Information Administration (EIA). That’s about half of what EVs will need to not use fossil fuels like coal. Moreover, under the current view of EVs, they will be using all of the renewable energy generated in the U.S., so there won’t be any left for buildings. The shortfall of green power will lead to an increase in coal production, which would mean more emissions, particulates, toxins, and pollution. Though oil is dirt, unit to unit, oil emits less carbon. Also, EVs don’t resolve any of the fragmentation problems caused by massive highway infrastructure. So I think it’s a huge waste of time and money to create an alternative to the combustion engine that doesn’t make our lives better, reduce our environmental impact, and improve climate change.


Instead of big renewable energy plants, you call for a decentralized approach to energy production within buildings. What is the benefit of large-scale use of on-site solar panels over big power plants? Also, while you note the possible environmental damage of other renewable energy approaches, you don’t discuss the fact that solar panels require mining elements and the use of chemicals. What are the possible negative environmental impacts of widespread use of solar? Are there more environmentally-sound ways to produce panels for use in buildings?

Decentralized power production is a much more democratic way of generating and distributing energy. Also, building integrated photovoltaic panels (BIPV) don’t take up additional space that large-scale arrays do. For me, it seems counter-productive to build these huge solar energy plants in the middle of nowhere when you can produce the same amount of energy within and on top of buildings where people are. I think one of the unseen benefits for BIPV for houses n this economy is that a PV array would increase the value of your home. Many of the large-scale solar farms that are proposed are sited in wilderness that is extremely fragile. This is the same mentality about energy production as that of coal and petroleum. As the dialogue of sustainability disregards the health of natural lands for the good of society, the movement has broken down and become dysfunctional. I feel the same way about advocates for nuclear power based solely on the fact that these facilities don’t emit carbon during energy production…and they call it clean. However every step in the process before and after the energy is created is highly dangerous and toxic to all living things. 

You do point out that solar panels just like every other type of energy generation device will cause environmental damage – it’s part of the problem with how we conceive of energy from the very beginning. All of the electricity we use is artificially created, meaning it’s not naturally formed electricity such as that from lightning. If we want to really look at how to deal with the energy issue in our society, we should first look to nature and ask the question, “Why aren’t other species using power?” I really think that should be the basis of how we resolve the huge problems with energy production, consumption and conservation. On-site energy production is not that far fetched. Most homes and buildings have their own boilers and cooling systems. This hasn’t always been the case.

In places like NYC, there are large steam networks for heating buildings. Solar panels aren’t the best energy producers out there so I don’t usually advocate for them too much. I really like them but it’s hard to show return of investment without government incentives. I really see hydrogen fuel cells as the future for on-site energy. Everyday, more buildings and homes are disconnecting from the grid because they have hooked up to a fuel cell. There are communities throughout the world that run completely on hydrogen now. The costs of residential size fuel cells are falling too.


You state: “While architects and city planners are the one who design our megalopolises, only conservation biologists are looking at issues of ecological and land management at that scale.” This is false on a few fronts: Landscape architects have long played a central role in integrating nature into cities and, since Frederick Law Olmsted, the designer of NYC’s Central Park, have been focused on expanding the amount of green space available in urban areas to maximize public health. You seem to omit landscape architects from your discussion. Why leave out a whole professional field?

When I say architects, I’m including landscape architects. I agree that many designers have contributed to the state of cities and regions around the world. You mention Frederick Law Olmsted and Central Park (a park that is dear to my heart having lived in NYC for more than a decade). Central Park and other urban parks serve as respite from the density and crowdedness of cities. Central Park has recorded nearly 200 different kinds of bird species within it. But it’s not a habitat – at least not in the sense that I layout in Urban Green. Conservation biologists point to specific criteria for what habitat is. For example, wilderness should be able to sustain a large population of megafuana while also contributing to continental conservation strategies of interlinking wild lands together to function as a true ecological system. Many design professionals call their work ecological – in a simpler way as your question suggests. But green buildings and the majority of park spaces, greenscapes, and landscape architecture have not made the jump to a backdrop for total conservation biology. People like Josh Donlan, Illka Hanski, Viviana Ruiz, Reed Noss, Dave Foreman, and Michael Soule are envisioning a world that uses biology to paint a picture for restoring habitat at grand scales – both in size and content. Noss has worked with developers in the past to rethink real estate development in Florida to maintain panther populations. Other conservation biologists have re-examined highway design so that less species are killed by cars. The problem for designers, and I would say landscape architects the most, is that the scope of a project as well as the education and training they receive fight against the level of implementation needed to marry conservation biology with architecture and city design…that is the continental scale. 

I would also say that landscape architecture should be leading the charge for change within building design and construction. You are right to suggest that landscape architects have many of the pieces to really shift the paradigm, but in my experience, landscape architects are so often too dependent on civil engineers and typically never takes a lead role in projects. There are some landscape architects who are the exception, but in general landscape architects are not running projects when a site is dominated by building. I wish landscape architecture and architecture were the same thing…we shouldn’t have them separated. Nor should conservation biologists and ecologists be separated from architecture. Until the entire design professions reinvent themselves to discard methods and mentalities that pre-date our discovery of evolution and understanding of ecosystems, we will, most likely, continue to build buildings and design parks that are no more aligned with biodiversity than, say, a parking lot.   

Caroline Fraser, who writes on conservation for The New Yorker, thinks beavers are the “original landscape architects” given the way they manipulate and redesign the environment, but ultimately provide valuable ecosystem services. In your book, you say more community developers actually need to think like beavers, who may seem to wreck environmental havoc in the near term, but are sustainable in the long-run because they move to new locations when they run out of trees to use to build dams. What lessons can we take from the beaver’s approach?

I love beavers and the lessons they can teach us about ourselves. First, they let us know we are not as unique as we would like to believe – meaning, we are not the only species on this planet that is unsustainable. I realized that as I wrote Urban Green. I had the great fortune of speaking with Dr. Clive G. Jones, Terrestrial Ecologist, Senior Scientist at Cary Institute of Ecosystem Studies. He pointed out that beavers are incredibly destructive – potentially as destructive as human civilization, except that the way they build things differs from us in three major ways:

1. Their structures are not built to last forever. In my book, I have images of a beaver dam that had to be removed using dynamite. It was that strong! But in general, their lodges and dams will degrade fairly quickly once they leave the area to settle in another place. Our dams like the Hoover Dam would take thousands of years to fall apart if people just suddenly disappeared or stopped managing it.

2. Though they have a large environmental footprint within a forest, they do not take over the entire ecosystem. The resulting beaver ponds will not flood the entire forest nor are they able to eat their way through all of the trees in the forest. This is a critical difference between human development and beaver development. It says that we would be much more intertwined in the natural world, if we built cities, parks, buildings and other things in a way limited in its domination of the natural lands it is within. 



3. The third thing we can learn from beavers is that disruption doesn’t have to equal fragmentation. This is the biggest sin of human development. We build things in a way that cuts off valid pathways for species, and we demolish large chucks of land while also putting under control other parts of the land – the end result is that ancient corridors to feeding, hunting, and mating grounds are completely separated from other areas that would provide water and protection. Beavers definitely build things and cause a disruption – they can flood acres and acres of a forest, they reorient the natural hydrology and have even been shown to cause certain riverbank species to become locally extinct. But the difference is that we don’t create a condition where other animals can’t thrive. For example, though their ponds are a big change to the habitat, they create hunting areas along their edge for fox and raccoon to find food. Birds of prey can hunt fish within the ponds. Moose find saplings along the shores of the beaver’s artificial lake while many other species thrive in the changed environment. The flooding of the forest floor also sets up a good opportunity for enriched soils, because all of the sediment trapped behind the beaver dam will settle and be ideal for new growth once the beavers leave and the water slowly drains.

I think one of the greatest lessons we can learn from beavers is that complex structures and extensive influence on ecosystems can co-exist with living in harmony with nature. In essence, only a few principles within society must change, and not society as a whole.

In your vision of ecological urbanism, you argue that nature can serve as a guide to the design of the built environment using a “ecomimicry approach.” Ecosystems could serve as the “foundation of design.” Ecologically-sound networks of green roofs, eco-corridors, and parks can serve as a foundation that enables co-habiting with nature. However, you also say: “Perhaps the next generation of green roofs will be designed not by architects but by urban designers and planners in partnership with ecologists and conservation biologists. Or maybe there will be no designer at all, and biologists will design the essential parts of our future cities.” Why leave landscape architects out of this mix considering they have long served as an intermediary between architects and biologists and have professional training in ecology and plant biology?

I wasn’t my intention to leave landscape architects out of the mix. Landscape architects should take a leadership role in redesigning the way we design our cities and buildings. I think that landscape architecture should begin to incorporate into their training all of the fundamentals of architecture, engineering, planning, energy, ecology and biodiversity. One of the points I make in Urban Green is that we should become keystone species – and I think that landscape architects have a leg-up on other design professionals such as architects or mechanical and electrical engineers. But for us to really reverse the problems we see throughout the natural world, design projects will need to interconnect with larger topics such as ecological history, biogeography, and meta-populations to insure a much more robust and spirited transformation of our current civilization. When every designer, be it landscape architect or engineer or city planner, is using biogeography – vast wilderness and species reintroduction – as guiding principles of designing the many parts of our society, we will see less and less problems like energy storage, water pollution, climate change, and resource depletion.

Lastly, you argue that people can learn from nature and become a “keystone species.” What are some positive examples of how people are acting like keystone species? What are the models that need to be scaled up?

A project I’ve been involved with is restoring oysters to an area in Myrtle Beach, South Carolina, to help improve the water quality of the area. Others are also taking this approach to restore shorelines, stabilize tourism, and maintain real estate values. The side effect of using oysters instead of filtration facilities is that you also create nodes for biodiversity for game fish, crab and shrimp. Oysters are also being found to improve the air quality. Such projects are happening throughout the Gulf of Mexico and from Florida to Rhode Island. These are examples of design doing more with ecology instead of always depending on technology. With many of these projects, people aren’t yet the keystone species, but they are beginning to function in the same way beavers do within a forest. You might call these people ecosystem architects. Right now, these oyster restoration projects are not interconnected, and are only locally beneficial. Several challenges face scaling up these efforts to have national and international benefits. For example, some states do not allow oyster restoration projects to be established within estuaries and tidal basins. Of those that are lawfully installed, they have to continue to cultivate new spat to introduce to the colonies because a meta-population of oysters does not exist within the Atlantic seaboard. 

In Urban Green, I also point to the Florida Everglades Restoration Project as a viable example of how people can de-engineer an area to improve the ecological functionality of an ecosystem. The efforts in the Everglades has shown that less engineering is actually better than more…and that ecology serves cities and people better than technology. Likewise, the biggest challenge is to see the Everglades as the tip of the iceberg for a much more encompassing plan to save nature and society because what starts in the swamps of southern Florida should continue up into the evergreen forests of Maine and then across Canada to British Columbia and then back down to Mexico City. This is the size we need to begin to think in as we talk about green buildings and landscapes. This is how we will become keystone species.

A recent report from the United Nations Intergovernmental Panel on Climate Change (IPCC) states that “warming of the climate system is unequivocal.” According to the IPCC, average global temperatures are increasing at an alarming rate. In just the past 50 years, northern hemisphere temperatures were higher than during any other 50-year period in the last 500 years, perhaps even the past 1,300 years. The IPCC projects that the Earth’s surface temperature could rise by as much as 4°C within the next century.

The primary cause of climate change is increasing concentration of greenhouse gases (GHGs), especially carbon dioxide (CO2) in the atmosphere. The 2007 Assessment Report by the IPCC indicates that GHG emissions increased by 70 percent between 1970 and 2004. These gases are primarily emitted as a result of human behavior, such as the burning of fossil fuels to produce energy. Building consturction and energy use account for more than 30 percent of worldwide emissions, while the transportation sector is responsible for another 30 percent.

Experts predict that the increase in the Earth’s temperature, if left unchecked, will have devastating effects. According to the IPCC, the projected sea level rise could reach 19-23 inches by the year 2100. Additional impacts could include increased spread of diseases; extensive species extinction; drought and wildfires; mass human, animal and plant migrations; and resource wars over shrinking amounts of potable water. 

There are a range of landscape architecture-based mitigation strategies that, if employed at mass scale, can help reduce GHG emissions by 50-85 percent by 2050 and limit temperature rise to 2 degrees celsius, targets that the U.N. recommends. Given the effects of climate change are already being felt in many communities, landscape architecture-based adaptation measures are also now being planned and implemented across cities and countries.

In a completely revamped climate change resource guide, which is part of ASLA’s series of sustainable design guides and toolkits, there are hundreds of vetted Web sites, research studies, and projects to explore in the following areas:

New York City, Chicago, and Philadelphia increasingly view their contaminated inner-city brownfield sites as natural locations for large-scale solar installations. At the national Brownfields conference, each city explained how solar farms can be set up in the unlikeliest places, saving the money involved in cleaning up some of the worst sites.

Chicago Launches Largest Urban Solar Installation in U.S. 

In Chicago, Dave Graham, who works on the city’s brownfield program, said the City Solar project just “fell into our laps.” He was called into a meeting in the mayor’s office with representatives from Exelon and SunPower, and found they wanted to create a massive solar farm on a derelict brownfield site. Actually, massive is an understatement for this project: it’s the largest urban solar plant in the U.S. Its 32,000 photovoltaic (PV) panels provide 10 MW of energy, enough for 1,500 local homes. In addition, GPS tracking systems help tilt the panels, ensuring the most efficient use of solar energy.

Heavily contaminated sites can cost up to $150,000 per acre to clean up. The West Pullman site for City Solar, which “has a variety of issues,” would have cost $20 million alone to clean up, “something no one in the city wanted to invest in.” As a result, Exelon simply put solar panels on top of the site, leaving the worst soils untouched underground. In some cases, where PV structures need to be installed, the team did actually discover underground storage tanks, which they then removed.

Throughout the process, the local community was consulted. Some residents had concerns about living so close to the new power facilities. Graham said one plus is that the facility is totally quiet.

In the construction process, some 200 jobs were created, “all local labor.” Additional jobs may be created if Exelon moves into the abandoned lead-ridden site next door.

Philadelphia Takes Advantage of Solar America Grants

Philadelphia won a Solar America Cities grant, which they will use to help create renewable power purchasing agreements. Kristin Sullivan, Philadelphia Mayor’s Office for Sustainability, said a number of city-owned sites are already being prepped for solar. In an example of multi-use infrastructure, Philadelphia Water Department’s treatment facilities will also host panels, generating 250 KW of power.   

In addition, the city will soon be issuing a request for proposals for a new three MW facility. Sullivan said Philadelphia hopes to encourage private sector developers to take the lead on creating solar power plants, even on city-owned lands. This makes more financial sense for the city then owning and operating its own solar power facilities.

The city government will soon release a solar hotspots map covering underutilized centers. The idea is to identify places, including brownfields, with little or no shading issues. Philadelphia also hopes to encourage large-scale distributed power via residential rooftops.

New York City Incentivizes Reuse of Brownfields

New York City launched SPEED, a searchable database of brownfield properties, a “real estate search engine”, that has gotten great traffic from the local developer community. Dan Walsh, Mayor’s Office of Operations, New York City government, said SPEED includes historical maps so developers can “toggle through time” and explore some 3,150 vacant commercial and industrial brownfield sites spread throughout the city. The idea is to use some of these sites for solar power plants.

To make it even easier for developers, the city launched a $9 million brownfield reinvestment fund. Each developer of a brownfield site gets $60-140,000 “fast” if they commit to cleaning-up a brownfield or redeveloping for energy uses. The grants can be used to cover expenses involved in design, investigation, clean-up, or insurance, says Walsh.

For brownfield sites that will be used by the public, the city has also launched a Green Property Certification program, which can be shown on site as proof that the area is fit for its intended use. “This is a voluntary, not regulatory program.”

Interestingly, none of these urban policymakers discussed how to turn parts of these new solar facilities into public spaces. Solar facilities need not be cut-off from neighboring communities. If designed well, they can also offer green space or even wildlife habitat. As an example, see Walter Hood’s model solar campus project at the University of Buffalo, which will be both public art installation and 1.1 MW solar power facility.

Watch an animation from ASLA’s Designing Our Future: Sustainable Landscapes online exhibition that explains how to use the landscape to reduce the energy consumed by a typical suburban home. See how smart tree placement and green roofs and walls dramatically improve energy efficiency.

Trees are being cut down to make way for new single-family homes, which then often sit on bare lots. These treeless lots not only have negative impacts on the climate, environment, and community health, but they also exacerbate the energy inefficient practices found within homes. This is a major problem given the average American home consumes 70 million BTUs annually. In fact, taken together, American homes account for 22 percent of total energy use as well as nearly 22 percent of carbon dioxide emissions (1.19 billion metric tons).
(Source: The Washington Post and Architecture 2030)

McKinsey & Co, a management consulting firm, found that energy use in the U.S. could be cut by 23 percent by 2020 by implementing simple energy efficiency measures. While homeowners can take low-cost steps to make the inside of their homes better insulated and therefore more energy efficient, the landscape isn’t often seen as a part of the problem… or the solution. Basic green technologies like smart tree placement and green roofs and walls can be used to dramatically reduce energy usage inside homes. If placed strategically, trees can reduce summertime cooling energy needs by 7-47 percent and wintertime heating needs by 2-8 percent.

In addition, well-designed residential green roofs, which are growing popular in some parts of the world, can reduce energy usage in both summer and winter. According to one Canadian study, a 32,000-square foot green roof on a one-story commercial building in Toronto reduced energy usage by 6 percent in the summer and 10 percent in the winter. Similarly, the green roof of the American Society of Landscape Architects (ASLA) at just 3,000 square feet reduces energy usage by 3 percent in summer and 10 percent in winter. Weather, roof, and building size and location also have an impact on the amount of energy savings. Lastly, fast-growing green walls can also reduce energy use by providing insulation in the winter and limiting direct sunlight on walls in the summer. In hotter months they also cool air temperatures by up to 10 degrees.

At the World Future Energy Summit in Abu Dhabi, the Land Art Generator Initiative (LAGI) announced the winners of its innovative design competition aimed at coming up with new models for integrating renewable energy facilities into existing communities and ecologically-sensitive landscapes.

The design concepts for three proposed sites in the United Arab Emirates not only had to be beautiful, but also “capture energy from nature, convert it into electricity, and store, and/or transform and transmit electrical power to a power grid connection point to be supplied by others” (see earlier post). In addition, the artistic solar facility must not create pollution, additional CO2 emissions, or have any local environmental impact: “Each entry should provide an environmental impact assessment in order to determine the effects of the project on the ecosystem into which the installation is to be constructed. Mention should be given to a mitigation strategy that will address any foreseeable issues.” According to The New York Times, winning projects may be built in United Arab Emirates sometime over the next few years.

The jury reviewed hundreds of projects from 40 countries and selected three winners:

1st place: Lunar Cubit, Robert Flottemesch, Jen DeNike, Johanna Ballhaus, and Adrian P. De Luca (see image above)

“Using frameless solar panels reduces embodied energy by nearly 30%, reducing time to be energy positive from seven years to five years. Around the pyramids flow natural stone paths in a repeating pattern that mirrors buried electrical cables, conducting electrons from the outer pyramids to the central pyramid where inside they are transformed into AC energy and transmitted to the Utility Grid. Co-locating walking paths and conduit runs minimizes the footprint of disturbed land during the construction allowing the maximum amount of natural ecosystem to remain untouched.”


2nd place mention: Windstalk, Darío Núñez Ameni and Thomas Siegl, with Atelier dna (concept and design), Gabrielle Jesiolowski (narrative), Radhi Majmudar PE, with ISSE Innovative Structural and Specialty Engineering (structure and engineering), Ian Lipsky, with eDesign Dynamics (ecology and renewable energy strategy).

“Our project consists of 1203 stalks, 55 meters high, anchored on the ground with concrete bases that range between 10 to 20 meters in diameter. The stalks are made of carbon fiber reinforced resin poles, 30 cm in diameter at the base and 5 cm at the top. The top 50 cm of the poles are lit up by an LED array that glows and dims depending on how much the poles are swaying in the wind. We roughly estimate that the overall output of our project is comparable to that of a conventional wind turbine array. While a single wind turbine that is limited in height to 55 meters may produce more energy than one of our Windstalks, our Windstalks can be packed in denser arrays.”

3rd place mention: Solaris, Hadrian Predock, John Frane (principals) and Chris Schoeneck, Johanna Beuscher, Heinrich Huber (design team)

“A curved, mirrored, mylar surface is designed to concentrate the sun’s rays of energy onto a cell of highly efficient photovoltaic material. The concentrated cell produces around 300-400 times the energy than that of a conventional cell. With close to 25,000 solar cells the Solar Canopy will produce on average 73,000 megawatt-hours per year – enough to power the country of Chad for a year.”

At the Energy Innovation 2010 conference, a number of leading experts on renewable energy, climate change, and sustainable transportation systems like electric vehicles, argued that innovation goes way beyond simple investments in research and development, but encompasses a comprehensive “innovation ecosystem” guided by consumer demand, supply of scientific research and marketable technologies, geographic clusters of firms, and the structures of government institutions. All these factors together will determine if the U.S. can continue to generate “game changing” next-generation technologies that can create more sustainable communities.

Incentivizing Clean Energy Production

Roger Pielke Jr., author of “The Climate Fix: What Scientists and Politicians Won’t Tell You About Climate Change,” says top-down, UN-led negotiations on climate change, which aims at creating global and then national greenhouse gas (GHG) emission targets and action plans, has largely failed. Instead, Pielke argues countries need to go “straight to innovation.” However, even then, there are still issues with setting national targets. For example, the UK “has the most ambitious CO2 target in the world — a 34 percent reduction of 1990 emission levels by 2020, but is finding it won’t be able to achieve this. “It would mean becoming as carbon-efficient as France in the next 2-3 years. The UK would need to add 30-40 nuclear power plants.” Realizing the difficulties, the UK is considering moving back its clean energy production targets.

To truly incentivize clean energy production, current undesirable forms of energy production must be taxed and those taxes must be used to finance the next generation of technologies. Pielke said both India and Germany are leading the way — India is adding a small 30 cent tax for each ton of coal. Those funds are then being reinvested in new energy technologies. Similarly, Germany is taxing nuclear rods because it hopes to move away from nuclear power. Germany is expecting to raise $40 billion for energy innovation.

Devon Swezey of the Breakthrough Institute built on this idea, adding that the “clean energy tigers” in Asia (Japan, China, and South Korea) will outspend the U.S. on government and private investment in energy innovation by a ratio of 3-to-1 over the next ten years. In addition, major global technology and energy firms like IBM, Applied Materials, Intel are now bypassing the U.S. and setting up their clean energy technology labs in China.

To keep these firms’ energy research here, the U.S. must invest in its entire innovation system — not just testing and deploying cutting-edge technologies, but opening and keeping open clean energy power plants and manufacturing facilities. “Manufacturing is part of the innovation ecology. If we lose capacity, parts of the clusters will move overseas.” Overall, panelists argued that increased investments in government energy R&D and investment isn’t enough — there must also be a focus on harnessing the innovation ecosystem and “process innovation” for new energy solutions to become reality across the U.S. 

Getting Americans to Love Electric Vehicles  

Robbie Diamond, President and CEO of Securing America’s Future Energy (SAFE) and the Electrification Coalition, said only in the U.S. are there “more cars than people,” with 1,100 cars per 1,000 people. In China and India, the rate is closer to 9 per 1,000, and even in western Europe, it’s around 700 cars per 1,000. While this demonstrates an incredible car-dependency and explains the enormous demand for imported oil, the amazing number of U.S. cars may also provide an opportunity. Diamond argued that the U.S. could be the key market for electric vehicles just because American families often have 2-3 cars.

Unfortunately, to date, there are only 1.6 million hybrid vehicles on the road, “mainly in niche markets in coastal cities,” and an even fewer number of electric vehicles. Still, Diamond sees electric vehicles as “the killer app” for revolutionizing the energy sector. A host of other applications, including smart meters, could spring up from electric vehicles (see earlier post). Also, the market may be there if costs can be brought down and consumers are better educated about the benefits of vehicles. “Right now, a big stumbling block is that electric vehicles don’t get 400 miles per tank, but most car trips are 10 minutes or less,” Diamond said. Electric vehicles need to somehow connect with consumers.

Transforming the Built Environment

Cathy Zoi, Acting Under Secretary for Energy and Assistant Secretary for Energy Efficiency and Renewable Energy, Department of Energy, plugged her department’s new Better Buildings program, which received nearly half a billion in recovery funds. Better Buildings is about scaling up building energy efficiency retrofits to the neighborhood level. The goal is to create a business model for “neighborhood by neighborhood” retrofits that leverage economies of scale. “We want to get to 5-10 million homes being retrofitted for energy efficiency in the next few years.”

Zoi outlined a story about the creation of Energy Star, which she said came out of the information technology sector and then spread to all appliances. She said the Energy Department saw in the early dates of mass computing that laptop computers shut down automatically, but desktop computers were often left on all night because users feared that their data would be lost. Going to the major manufacturers, Zoi and her team asked why couldn’t desktops also be programmed to shut down automatically. One engineer said, “Oh, this is very easy, but our marketing department didn’t see any point in this so they blocked that feature.” So marketing departments everywhere could see the benefit, the Energy department created the Energy Star logo, which helped “pull the market forward.” Now, with the Obama administration’s more stringent appliance energy efficiency standards, “we will see a $350 billion savings in energy usage.” Zoi said this model — “institutionalizing efficiency so energy efficiency is easier than inefficiency” will be crucial to expanding green buildings across the U.S.

The Department of Defense is taking a similar approach. Dr. Jeffrey Marqusee, Executive Director, Strategic Environmental R&D Program, said defense bases act are “small communities in themselves, with hospitals, stores, housing, and offices.” To address the defense department’s monster energy needs (it’s the largest single consumers of energy in the world), “we’ll need to deploy retrofits over our whole stock of buildings.” One-off green showcases will no longer be enough.

Finding the Game Changers

In addition to electric vehicles, incentivizing new energy innovation, and scaling up energy efficient building retrofits, some government officials are also trying to find the “game changing” energy solutions that will make current technologies obsolete.

Dr. Arun Majumdar, Director, Advanced Research Projects Agency – Energy (ARPA-E), sees the potential rise of “electro-fuels,” as well as energy that uses carbon dioxide as a basic feedstock. In this scenario, the key driver of climate change would instead become the source of new energy. He also said key components of the future smart grid, like an “operating system” and more powerful and efficient transformers, still haven’t been created yet.

Cathy Zoi at the Energy Department said her department’s “Sun Shot” program aims to create a next-generation solar panel in five years that can provide one kilo-watt of energy at 5-6 cents. “We are investing in a new way to do solar.” There was also discussion of small-scale modular nuclear reactors (see earlier post). “The Navy has been using these for a really long-time (in nuclear submarines),” but these could power installations and bring down the cost of reactors. As Dr. Marqusee noted, however, the questions is will local communities want a small-scale nuclear reactor in their backyard?

In future debates on next-generation energy technologies, perhaps there will also be more discussion on what this all means for the built environment and sustainable community development.  For instance, what role can design professionals (landscape architects, planners, environmental engineers, and architects) play in helping communities leverage this coming infrastructure? How can electric vehicle powering stations and smart meters, solar and wind power plants, and retrofitted neighborhoods be well integrated into pioneering sites so demand for them only grows?
