“Sustainable development” has generated substantial buzz since the concept was brought into focus by the Brundtland Commission’s now famous 1987 report, Our Common Future. The Commission defined the concept as “development that meets the needs of the present without compromising the ability of future generations to meet their own needs.”

Since then, the definition has been debated and adapted for specific purposes throughout policy, academic, governmental, and organizational circles. Many of these interpretations are only relevant to the circumstances in which they are applied. In the context of biomass and biofuels, sustainability standards are specific rules and criteria by which the production, transportation, and processing of feedstocks can be assessed for their environmental, social, and other values.

In the international community, sustainability guidelines for biomass have begun to emerge, but remain aspirational at best. While high oil prices, increasing pressures to mitigate climate change effects, and efforts to boost rural agricultural production throughout the world will continue to sustain support for the development of biomass and biofuel resources, environmental concerns will temper optimistic projections for the industry.

The U.S. Chamber of Commerce has announced it will mount a legal challenge to the Environmental Protection Agency’s decision to limit greenhouse gas emissions under the Clean Air Act.

Steven J. Law, the chamber’s chief legal counsel, said the business group would not question the science behind global warming but rather would challenge the process by which the EPA decided it had the right to control carbon dioxide emissions as a threat to human health.

The Obama administration has said it would prefer that Congress pass a law regulating carbon emissions, but with the passage of such a law looking increasingly unlikely, a battle is shaping up over the EPA’s possible efforts to control CO2 emissions.

Wind power capacity grew by 31 percent globally in 2009, with the steepest rise occurring in China, according to a new study.

About 37.5 gigawatts of capacity were added last year, boosting the total capacity worldwide to 157.9 gigawatts, says the Global Wind Energy Council, an industry trade group based in Belgium.

The growth occurred despite the weak global economy as major nations made renewable energy a priority of their economic stimulus plans, said Steve Sawyer, the council’s secretary general.

This post comes from Rev. Canon Sally G. Bingham, the founder of the San Francisco-based Interfaith Power & Light, a national campaign with affiliates in 30 states. The group is organizing the Valentine’s Weekend Preach-In on Global Warming.

Valentine’s Day typically conjures up images of roses and sweets for our loved ones, a time when we recognize the many virtues of romantic love. Yet this coming Valentine’s Day, leaders of communities of faith throughout the United States will be bringing forth a different kind of love — a deep, abiding love for God’s creation and our neighbors now threatened by the calamity of global climate change.

Hundreds of congregations of many faiths have signed up for a National Preach-In on Global Warming on Valentine’s Day weekend. We are showing our love for the poor, disadvantaged and most at-risk peoples and creatures of the world on this traditional day of love.

SunPower, Silicon Valley’s biggest solar panel manufacturer, announced Thursday an agreement to buy SunRay Renewable Energy, a developer of solar power plants in Europe and Israel, for $277 million.

Although based in Malta, SunRay is managed by Israelis, including CEO Yoram Amiga and Michael Barnea, Head of Legal and M&A. SunRay established a wholly-owned Israeli subsidiary, SunRay Israel Blue & White, which is working to develop 100 megawatts of solar photovoltaic projects.

Kobi Katz, the CEO of SunRay Israel, told The Marker the sale was a vote of confidence by SunPower in the Israeli solar market.

Researchers at the University of California, Los Angeles have created a synthetic “gene” they say can capture carbon dioxide emissions.

Omar M. Yaghi, a professor of chemistry and biochemistry, has developed thousands of so-called crystal sponges that absorb gases and have proven effective in the lab at storing CO2.

The synthetic crystals, which code information in a “DNA-like manner,” have nanoscale-sized pores that Yaghi says allow molecules to go in and out.

We’re in for some climate chaos. The Copenhagen Accord means at least two to four degrees of warming over the next fifty years — and who knows how much “global weirding.” As greenhouse gases trap more heat, or energy, close to the earth, and that energy is used by large weather systems, which move faster and are more intense than ever.

This means more Category 5 hurricanes. More likelihood of Florida snow. My biggest concern about all this change? Eating. If crop yields drop 80 percent as they’re expected to, if we don’t adapt to a changing climate, I might get hungry.

So how do we produce food in a changing climate? How do we produce food with shortages of oil and fuel around the corner? Well we might start, like Joel Salatin’s family-owned Polyface Farm in Virginia, by decreasing inputs to the farm.

With this post, CleanTechies is diverging from our usual content with this light-hearted Valentine’s Day tribute to clean energy from the Vote Solar Initiative, which is working to make solar power mainstream.

People love solar. There are plenty of reasons why that’s the case. Solar creates local jobs. It produces reliable electricity when we need it most. It improves energy independence by tapping a homegrown resource. It offers real hope in the fight against global climate change. And ultimately the idea that we could be harnessing electricity from that big, yellow sun of ours just makes people feel good.

Always up for a good sun pun, Vote Solar thought we’d hammer that point home with a tongue-in-cheek Valentine Video campaign. (more…)

The National Resources Defense Council Action Fund released a video clip last week designed to echo Obama’s call to move America towards a “clean energy economy” in his State of the Union address.

The video is part of the “This is Your Moment” campaign, which features a host of celebrities, such as Jason Bateman, Leonardo DiCaprio, Felicity Huffman, Justin Long, Edward Norton, and Forest Whitaker, urging Congress to pass the first-ever climate and clean energy bill, currently pending in the Senate.

IBM researchers have increased by 40 percent the efficiency of a thin solar cell that can be applied like ink and that uses widely available materials.

The new cells can convert solar energy into electricity with an efficiency of 9.6 percent, a significant improvement on the 6.7 percent high for existing technologies and close to the level that would make the cells practical for use in commercial solar panels, according to a report published in the journal Advanced Materials.

The new technology uses a semiconductor material made of fairly abundant elements — including copper, zinc, tin, sulfur and selenium — and utilizes an inexpensive ink-based process in creating the cell.
