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.

Scientists have found new evidence that the Earth's natural feedback mechanism regulated carbon dioxide levels for hundreds of thousands of years. But they say humans are now emitting CO2 so fast that the planet's natural balancing mechanism cannot keep up.

BEIJING, April 28 -- CHINA is looking to expand wind power generating capacity to 100,000 megawatts by 2020, or fivefold the previous target, an industry official said. "The NDRC has just recently completed an internal meeting to discuss the possibility of increasing wind power capacity to 100,000MW," Shi Pengfei, vice president of Chinese Wind Energy Association said, referring to the National Development and Reform Commission, China's top industry planning body. "It's not 20,000MW or 30,000MW as previously targeted."

The challenges our society faces with depleted energy resources, water shortages, soaring food costs all point to environmental solutions.

OSLO (AFP) - Projects to reduce carbon dioxide emissions in developing countries have prevented 135 million tonnes of CO2 emissions from entering Earth's atmosphere so far, the Norwegian classification group Det Norske Veritas (DNV) said on Monday. The projects, known as Clean Development Mechanisms (CDMs) and defined in the Kyoto Protocol, allow industrialised countries and their companies to finance projects aimed at reducing greenhouse gases in developing countries.

From production to processing, transport to trash can, meals and snacks can leave a large environmental footprint. One company aims to slow this trend with a new low-carb menu. Carbs - as in carbon.

(NaturalNews) For decades, battery storage technology has been a heavy weight on the back of scientific innovation. From cell phones to electric vehicles, our technological capabilities always seem to be several steps ahead of our ability to power them. Several promising new technologies are currently under development to help power the 21st century, but one small start-up looks especially well positioned to transform the way we think about energy storage.

Last week saw the opening of the first hydrogen fuelling station in England. The station is based at Birmingham University, where experiments are being carried out to test the viability of hydrogen in transport applications, as part of Birmingham's 'Science City' hydrogen energy project.

A light emitting diode (LED) is an III-V semiconductor device that can convert electrical energy into visible light, a phenomenon called electroluminescence (EL). In recent years, labs have been fine-tuning this device to the point now that it is used with ever more frequency in the manufacture of auto lamps.

Global wind power capacity reached 94,100 megawatts by the end of 2007, up 27 percent from the previous year, and then topped 100,000 megawatts by April 2008.1 (See Figure 1.) The roughly 20,000 megawatts installed in 2007 was 31 percent above the 2006 record for capacity additions.2 (See Figure 2.) New wind installa­tions were second only to natural gas in the United States as an additional source of power capacity and were the leading source of new capacity in the European Union (EU).3

WASHINGTON (April 23, 2008) - An investigation of the Environmental Protection Agency released today found that 889 of nearly 1,600 staff scientists reported that they experienced political interference in their work over the last five years. The study, by the Union of Concerned Scientists (UCS), follows previous UCS investigations of the Food and Drug Administration, Fish and Wildlife Service, National Oceanic and Atmospheric Administration, and climate scientists at seven federal agencies, which also found significant administration manipulation of federal science.

it is clear that soaring oil prices are undermining the benefits of debt cancellation in some countries, especially poor oil-importing nations.

Demonstration Projects Aim at 15 Percent Reduction of U.S. Peak Load Electricity Demand Washington, DC- U.S. Department of Energy (DOE) Assistant Secretary for Electricity Delivery and Energy Reliability Kevin Kolevar today announced the Department's plans to invest up to $50 million over five years (Fiscal Years 2008 - 2012), subject to appropriations from Congress, in nine demonstration projects competitively selected to increase efficiency in the nation's electricity grid.
