One of the biggest challenges renewable-energy projects pose is that they often take up much more land than conventional sources, such as coal-fired power plants. A team of scientists, several of whom work for the Nature Conservancy, has written a paper that will appear in the journal PLoS One showing that it can take 300 times as much land to produce a given amount of energy from soy biodiesel as from a nuclear power plant. Regardless of the climate policy the nation adopts, the paper predicts that by 2030, energy production will occupy an additional 79,537 square miles of land. The impact will be "substantial," said Jimmie Powell, the Nature Conservancy's national energy leader and one of the paper's co-authors. "It's important to know where the footprint is going to be."
And this last one really demonstrates the mindset:
The Natural Resources Defense Council and the National Audubon Society have created an online mapping project, using Google Earth, of 13 Western states to show where renewable projects would have the most impact. Out of the 860 million acres in those states, for example, there are 10,000 conservation areas, and 128 million acres are off limits to energy development.
"Do people think it's better all those birds are breathing CO2? I'm not a scientist, but I doubt it," said Engel, whose company is expanding its U.S. manufacturing and distribution operations. "Let's get the facts on the table and not the feelings. The fact is, these are not issues."
