Windenergie in den USA:
Percentage wind generated vs. total energy production:
Denmark: 19%
Germany: 5.5%
United States: 0.4%
Total installed wind power capacity: 39,292 MW:
Germany: 14,609 MW
United States: 6,374 MW
Denmark: 3,110 MW
Canada: 312 MW
Auszug aus http://www.westernwindenergy.com/strategy.php über die Economics der US-Windenergie-Betreiber: At a robust wind location, each one megawatt installed, or US $1 million capital invested, $166,000 is generated annually in revenues, plus $55,000 in “federal tax credits” (PTC) and $600,000 in first year write-offs.
Wind developers have three revenue sources:
Electrical sales: 3 – 7.5 cents per kw/h
Renewable Energy Credits: 1 – 3 cents per kw/h
Production tax credits: 1.8 cents per kw/h
Operations and maintenance costs are well defined, easily controlled, based on manufacturer’s warranties.
Natural gas fuel costs are US 5 cents kw/h compared to total cost of 1/2 – 1-cent kw/h for wind energy.
