Renewable Fuels May Provide 25% of U.S. Energy by 2025 (JOHN J. FIALKA, November 13, 2006, Wall Street Journal)
A new Rand Corp. study showing the falling costs of ethanol, wind power and other forms of renewable energy predicts such sources could furnish as much as 25% of the U.S.’s conventional energy by 2025 at little or no additional expense.
A second renewable-energy report soon to be released by the National Academy of Sciences suggests wood chips may become a plentiful source of ethanol and electricity for industrial nations because their forested areas are expanding, led by the U.S. and China.
Because use of renewable fuels to replace oil and cut emissions of carbon dioxide is an area on which Congress’s coming Democratic leadership and the Bush administration agree, the studies are likely to hasten efforts to increase production incentives next year, either in a new energy bill or a farm bill.
Cue the folks who reflexively claim there’s no other option but gasoline….
It heats. It powers. Is it the future of home energy?: Residential ‘micro-combined-heat-and-power’ units are efficient furnaces that create electricity. (Mark Clayton, 11/14/06, The Christian Science Monitor)
Factories and other industrial facilities have used large CHP systems for years. But until the US debut of micro-systems in greater Boston, the units had not been small enough, cheap enough, and quiet enough for American homes. Add to that the public’s rising concern about electric-power reliability – seen in a sales boom of backup generators in the past couple of years – and some experts see in micro-CHP a power-to-the-people energy revolution.
“Right now these residential micro-CHP systems are just a blip,” says Nicholas Lenssen of Energy Insights, a technology advisory firm in Framingham, Mass. “But it’s a … technology that … could have a big impact as it’s adopted more widely over the next five to 10 years.”
