U.S. wind energy industry installed 5,244 megawatts (MW) in 2007, expanding the nation's total wind power generating capacity by 45% in a single calendar year and injecting an investment of over $9 billion into the economy, the American Wind Energy Association announced today.
The preservation of coastal ecosystem services such as clean water, storm buffers or fisheries protection does not have to be an all-or-nothing approach, a new study indicates, and a better understanding of how ecosystems actually respond to protection efforts in a “nonlinear” fashion could help lead the way out of environmental-versus-economic gridlock.
One way of supplying energy is to grow plant material and burn it. If managed well most of the carbon released by burning the material will be captured by the growing plants, and so have a low impact on overall levels of atmospheric carbon dioxide.
Within five to seven years fast growing trees and grasses might become economically viable alternatives to corn as a source of renewable fuel ethanol, reducing the need for pollutants that now cause a massive "dead zone" in the Gulf of Mexico.
The same brown algae that cover rocks and cause anglers to slip while fly fishing contain oil that can be turned into diesel fuel, says a Montana State University microbiologist.
VTT Technical Research Centre of Finland has studied the profitability of using bush chips in electricity production in Namibia, where biomass from bushes has great energy production potential. Namibia suffers from the overgrowth of bush, which is disruptive to cattle raising, the country's primary source of livelihood. VTT also developed the production technology for bush chips.
