writes "Colorado State University's Rocky Mountain Collegian reports that, "as of June [the price of wind power] dropped to 1 cent per kWh." Even without further expected improvements in turbine technology, the U.S. would now need to use less than 3% of its farmland to get 95% of its electricity demand satisfied by wind power. Plus, wind power is the only mitigation of global warming, because if the whole world converted to wind power in 15 years, the amount of power being extracted from the atmosphere would be more than the increase in greenhouse gas atmospheric energy forcing since 1600. Don't say goodbye to coal and oil, yet, though; unless cell technology increases substantially, when we run out of oil we will convert coal to synthetic fuel." Update: 09/15 13:40 GMT
: Note: the "1 cent" figure refers to the premium paid for the power over conventionally supplied electricity, rather than the final per-kWh price.
