WorldChanging: Europeans Form Renewable Energy Agency - 0 views

  •  
    A consortium of European governments is developing the world's first International Renewable Energy Agency. The agency, known as IRENA, will serve as a global cheerleader for clean energy. It plans to offer technical, financial, and policy advice for governments worldwide, according to a joint announcement from Germany, Spain, and Denmark - the project's leaders.

    As fossil fuel prices rise, as oil insecurity deepens, and as concerns about climate change cast a shadow over the future of coal, a new energy economy is emerging in the United States. The old energy economy, fueled by oil, coal, and natural gas, is being replaced by one powered by wind, solar, and geothermal energy. The transition is moving at a pace and on a scale that we could not have imagined even a year ago.

CLIMATE CHANGE: 100-Percent Renewables Not a Pipe Dream - 0 views

    KINGSTON, Ontario, Jun 25 (IPS) - North America's abject failure to meet the challenge of climate change has been "un-American", environmentalist and scientist David Suzuki told delegates Tuesday at the World Wind Energy Conference, the first ever in the region. "We're facing an ecological crisis, a crisis far, far worse than Pearl Harbour," Suzuki said. Twenty years ago this week, one of the United States' leading scientists warned Congress of the imminent danger of climate change and said that waiting decades to take action was too risky. Now James E. Hansen of the National Aeronautics and Space Administration has published new research indicating that greenhouse gas concentrations have pushed the climate near a dangerous tipping point that will unleash far-reaching changes in the atmosphere and oceans that could take millennia to reverse.

Electricity: An Astonishing Abundance - 0 views

  •  
    Our story of energy begins when humans discovered the secret of fire. We burned wood and brush to protect ourselves from predators, cook food, and, later, to survive the ice age. In 12th-century Europe, with the forests fast disappearing, we started burning the strange black stones we called coal. Later, we used coal to produce steam, launching the Industrial Revolution.

Solar Thermal Power in North-Africa: How Much Land to Power the World? : TreeHugger - 0 views

  •  
    Spiegel Online published a series of pictures titled "Desertec: Strom aus der Wüste" (translation: Desertech: Electricity from the desert). It includes this image of how much land would be needed to power the world, Europe or Germany with solar-thermal power. The idea is similar to a post we did a year ago: How Much Land to Power The Whole World with Solar?

Solar Power Lightens Up with Thin-Film Technology: Scientific American - 0 views

  •  
    The sun blasts Earth with enough energy in one hour-4.3 x 1020 joules-to provide all of humanity's energy needs for a year (4.1 x 1020 joules), according to physicist Steven Chu, director of Lawrence Berkeley National Laboratory. The question is how to most effectively harness it. Thin-film solar cells may be the answer: One recently converted 19.9 percent of the sunlight that hit it into electricity, surpassing the amount converted into power by mass-produced traditional silicon photovoltaics and offering the potential to unleash this renewable energy source.
