Renewable Energy Realities

A great article debunking the "green" energy nonsense. Not only is it not economical, it ISN'T "green"!

Large-scale power generation from biomass would require that “vast areas be shaved or harvested annually,” Ausubel says. It would take 2,500 square kilometers of prime Iowa farmland to produce as much electricity from biomass as from a single nuclear power plant.

“Increased use of biomass fuel in any form is criminal,” Ausubel stated in a media release. “Every automobile would require a pasture of 1-2 hectares.” He added.

Wind power? While it’s much less land intensive than biomass, that’s not saying much. A 770-square-kilometer area would only produce as much electricity as a single 1,000 Megawatt nuclear plant.

A wind farm the size of Texas would be required to extract, store and transport annual U.S. energy needs. “Every square meter of Connecticut” would have to be turned into a wind farm to provide all of New York City’s electricity demands.

Solar power is also quite a land hog. As photovoltaic cells are only 10 percent efficient and have seen no breakthroughs in 30 years, U.S. electric consumption would require a 150,000-square kilometer area of photovoltaics, plus additional land for electricity storage and retrieval.
The photovoltaic industry would have to step up its production by 600,000 times to produce the same amount of power as that generated by single 1,000 Megawatt nuclear plant.

Aside from land misuse, Ausubel also raises the other undesirable consequences of renewables: wind power produces low-frequency noise and thumps, blights landscapes, interferes with TV reception, and chops birds and bats....and solar power would require that large areas of land be essentially “painted black” with photovoltaic cells.

In terms of resource use, the infrastructure of a wind farm takes five to 10 times the steel and concrete used in a 1970-vintage nuclear power plant.
