When a world class manufacturer like General Electric enters a business, quality goes up and prices come down. That's what has happened with wind power, since General Electric began making wind turbines.
Just since 2003, General Electric has driven the cost of wind power from its turbines down from 15 cents per kilowatt-hour to 5 cents per kilowatt-hour, a 65% reduction. See page 31 at:
As GE notes in its presentation to investors, the 5 cents per kilowatt-hour price is without any subsidies. That number makes wind power cheaper than new nuclear and new coal. It would be competitive with a new natural gas plant, if gas prices were at about $4 per thousand cubic feet and higher. The falling price of wind power is a key to the global wind boom that has seen about 240,000 megawatts of wind installed around the world, with nearly 50,000 megawatts in the USA.
Huge companies like General Electric and Siemens that is the leader in offshore wind can make big change happen quickly. The wind pricing revolution has been completed in less than a decade. Remarkable.
