Ethanol is becoming a component in an increasing amount of the nation’s fuel supply. Those who manufacture and sell it and the associations that represent them hail ethanol as the reducer of and, ultimately, the means for ending the nation’s dependency on foreign oil.
Those who have followed the solar photovoltaics (PV) industry for the last 15 years or more can be excused for feeling a tad skeptical about current claims that now the industry is on the verge of taking off.
Despite oil prices that hover around $100 a barrel, it may take at least 10 years of intensive research and development to reduce the cost of solar energy to levels competitive with petroleum, according to Harry Gray, Ph.D., who spoke at the 235th national meeting of the American Chemical Society (A
Competitively priced electricity from easily manufactured solar cells is the aim of a Penn State researcher’s project funded for up to $1,231,000 over three years by the U.S. Department of Energy (DOE).
Wind energy leaders in most categories held onto their No. 1 positions in the latest version of the American Wind Energy Association’s (AWEA) annual rankings of wind power leadership in the United States.
Researchers at the US Department of Energy’s National Renewable Energy Laboratory have moved closer to creating a thin-film solar cell that can compete with the efficiency of the more common silicon-based solar cell.
The Collegiate School in New York has partnered with Juice Energy Inc. to decisively reduce its carbon footprint. Beginning in mid-February, the school began purchasing green power equal to its total usage of 639,000 kilowatt-hours annually.
Science has relentlessly sought nature’s ability to turn sunlight into useful fuel. Recently, Penn State University researchers developed a device that could split water and produce recoverable hydrogen.
The case for wind power growth in the northern plains states just got stronger. In February 2008, a partnership of two utility companies announced plans for a large-scale transmission line, which will accommodate several new wind farm developments in North Dakota.
Pacific Gas and Electric Co. (PG&E) and BioEnergy Solutions announced that their biogas-to-pipeline injection project in Fresno County, Calif. has begun production of renewable natural gas derived from animal waste.
Debunking the notion that all renewable power rides in on the wind or the rays of the sun, a developer in Idaho is pioneering a revolutionary, clean technology in the state’s first geothermal power plant.
