Colorado wind power is rising with 1,880 huge turbines erected across the prairie, twisting white blades as long as soccer fields, a cleaner source of energy replacing fossil fuels.
It has reached the point where the wind turbines generated 67 percent of Xcel Energy’s Colorado-made electricity one morning in November and 54 percent for two 24-hour periods in October — feats unmatched around the nation, industry officials said Tuesday.
Falling costs, a state mandate, a federal subsidy and sheer momentum are driving the shift to renewable energy.
The proliferation of turbines here — doubling the number in 2009 — reflects a takeoff of wind power nationally that has cut carbon dioxide emissions by 132 million tons, American Wind Energy Association research director Michael Groggin said.
“That’s the equivalent of taking 28 million cars off the road, and this is going to…
