Balloon technology could cut cost of solar energy 90% by 2010
(2/21/2007) With high energy prices and mounting concerns over human-induced climate change, there is intense interest in renewable energy, especially solar, which produces no pollution and is readily available in the form of sunlight. In recent years, however, the solar energy market has been hampered by supply shortages of refined silicon, the critical resource needed for solar cell fabrication. Further, because solar installations traditionally require a large surface area to capture as much sunlight as possible, solar arrays often take up real estate, occupying land used agricultural production and other purposes. Without government subsidies, solar is not presently viable in many areas.

Savvy environmentalists challenge corporations to go green
(1/29/2007) Increasing rates of tropical deforestation in the 1970s and 1980s helped trigger the rise of several forest activist groups specifically interested in rainforests. Among the earliest of these organizations was the Rainforest Action Network (RAN). Founded in 1985 by Randall Hayes, RAN lead its first direct campaign in 1987 against Burger King, which at the time was using beef raised on deforested lands in Central America. In response to the nationwide boycott, which caused sales to drop 12%, Burger King canceled $35 million worth of beef contracts from the region and announced they would no longer import beef from the rainforest. Hailed as a major victory for rainforest protection, RAN initiated consumer boycotts of other firms engaged in destructive practices, eventually developing an effective strategy for promoting change at the corporate level. Today San Francisco-based RAN has expanded well beyond its original mission of protecting rainforests. Recently dubbed "the most savvy environmental agitators in the business" by the Wall Street Journal, the small but efficient organization (36 staff members and a $3 million budget) pressures some of the world's largest and most respected firms -- including Citigroup, Bank of America, JP Morgan Chase, Goldman Sachs, Home Depot, and Boise Cascade -- to adopt wide-ranging green policies that impact everything from where they source their energy to how they finance development projects.


Biofuels could decimate environment, stymie developing countries, says report
(1/25/2007) In his State of the Union Address Tuesday night, U.S. President George W. Bush highlighted ethanol fuel production as a means to improve domestic security by reducing dependence on foreign oil while at the same time helping to fight global warming. His call echoes a broader shift in sentiment among business and political leaders who believe that biofuels -- liquid fuels produced 'energy crops' including sugarcane, corn, soybeans, oil palms -- are a key future liquid energy source. In fact, next week, biofuels are likely to take a prominent position at the European Union's 'Sustainable Energy Week' in Brussels when 650 delegates will listen to speeches by the likes of Al Gore and UK foreign minister Margaret Beckett. With all the enthusiasm it may seem that biofuels are the end-all solution. A new report argues that this is not the case. In its briefing, 'International trade in biofuels: Good for development? And good for environment?' the International Institute for Environment and Development (IIED) cautions policymakers not to get caught up in all the hype. IIED warns that serious concerns still remain when it comes to the widespread adoption of these renewable energy sources.


Global warming cap to cost U.S. 0.26% of GDP says Energy Department
(1/23/2007) A proposed cap-and-trade system to curb U.S. greenhouse-gas emissions will cost the U.S. economy 0.26 percent of annual GDP according to a new study by the Department of Energy's Energy Information Agency (EIA). The EIA says that the plan would lead to higher energy prices inlcuding a 5 percent rise in the price of gasoline, an 8 percent climb in the price of heating-oil an 11 percent increase in the price of natural gas and electricity.


Bush calls climate change a 'serious challenge'
