But Can't We Just Find A Giant Hydrogen Mine Somewhere, Like Maybe On The Sun?

Study: Renewable Energy Not Green

article begins:

Renewable energy could wreck the environment, according to a study that examined how much land it would take to generate the renewable resources that would make a difference in the global energy system.

Building enough wind farms, damming adequate number of rivers and growing sufficient biomass to produce ample kilowatts to make a difference in meeting global energy demands would involve a huge invasion of nature, according to Jesse Ausubel, a researcher at the Rockefeller University in New York.

Ausubel came to this conclusion by calculating the amount of energy that each renewable source can produce in terms of area of land disturbed.

“We looked at the different major alternatives for renewable energies and we measured [the power output] for each of them and how much land it will rape,” Ausubel told LiveScience.

The results, published in the current issue of International Journal of Nuclear Governance, Economy and Ecology, paint a grim picture for the environment. For example, according to the study, in order to meet the 2005 electricity demand for the United States, an area the size of Texas would need to be covered with wind structures running round the clock to extract, store and transport the energy.

New York City would require the entire area of Connecticut to become a wind farm to fully power all its electrical equipment and gadgets.
