You are all clueless. Sparrow farts run through a gas turbine won't get you 10^20 joules/year. Not now, not ever. Pulling 10^20 joules/year out of wind or waves would monstrously perturb the weather. Where do the energy and raw materials necessary to fabricate and install your New Age hind gut fermentations originate? Who pays for the environmental impact reports and litigations therefrom?
What are the unknown hazards? Can you guarantee absolute safety for 10,000 years? Let's have a uniform set of standards, eginineering and New Age bullshit both. Area necessary to generate 1 GW electrical, theoretical minimum
mi^2
Area, Modality
====================
1000 biomass
300 wind
60 solar
0.3 nuclear
3x10^7 GWhr-thermal/year would need 9 billion mi^2 of wind collection area. The total surface area of the Earth is 197 million mi^2. 24 hrs/day. Looks like yer gonna come up a little short if 100% of the Earth were wind generators powering only the US.

Uncle AL,
Stanford Scientist say we
can get enough energy from the wind.
http://news-service.stanford.edu/new...nd-052505.html
A partial quote..."...After analyzing more than 8,000 wind-speed measurements to identify the world's wind-power potential for the first time, Cristina Archer, a former postdoctoral fellow, and Mark Z. Jacobson, an associate professor of civil and environmental engineering, suggest that wind captured at specific locations,
if even partially harnessed, can generate more than enough power to satisfy the world's energy demands. Their report appears in the May Journal of Geophysical Research-Atmospheres, a publication of the American Geophysical Union."
