Yeah, yeah. I know. You’re tired of me telling you “I told you so,” but once again, as usual, I am right and you are not.
Why we’re even fiddling around with this green alternative energy crap is beyond me. It doesn’t work for the most part, and what does work is extremely expensive and highly inefficient.
Renewable electric energy from nonhydroelectric sources — chiefly wind and solar — contributed only 3.6 percent of total U.S. generation in 2010 — yet received 53.5 percent of all federal financial support for electric power.
And wind power alone, which provides 2.3 percent of generation, received 42 percent of all support.
Wind and solar renewable energy have failed to thrive despite government support because they face substantial “market impediments,” according to Benjamin Zycher, a visiting scholar at the American Enterprise Institute (AEI).
“Energy policies in the United States for decades have pursued energy sources defined in various ways as alternative, unconventional, independent, renewable, and clean in an effort to replace such conventional fuels as oil, coal, and natural gas,” Zycher states on the AEI website, and “renewable electricity receives very large direct and indirect subsidies from the federal and state governments.
“These long-standing efforts have, without exception, yielded poor outcomes.”
Among the “market impediments” to large-scale development of renewable energy resources is the amount of land required for wind farms and solar facilities.
A wind farm would require 500 windmills, each producing 2 megawatts (MW) of energy, to generate 1,000 MW — assuming the farm operates at full capacity, which would be virtually impossible. Since wind turbines must be spaced apart to maximize production, a 1,000 MW farm needs from 48,000 to 64,000 acres of land — from 75 to 100 square miles.
In contrast, a 1,000 MW gas-fired plant needs about 10 to 15 acres.
As for solar facilities, it takes a square meter of solar energy-receiving capacity to produce, at best, enough power for a single 100-watt light bulb, according to Zycher.
Renewable energy also presents transmission problems. Wind farms are best suited for the Midwest and solar facilities for the Southwest, far from the coasts where most electricity is consumed, and this creates significant transmission costs.
One survey found that wind projects would have a median transmission cost of $15 per megawatt hour, compared to $3.60 in transmission costs for coal and natural gas.
Looking ahead to 2016, “the projected cost of renewable power is at least five times higher than that for conventional electricity,” says Zycher, author of the new book “Renewable Electricity Generation: Economic Analysis and Outlook.”
He concludes: “Despite these excess costs, political support for wind and solar power remains strong. No state has formally abandoned or weakened its renewable electricity requirements, and federal policies to promote renewable technology in electricity production remain in place.”
