Here is more good news on the falling cost of renewable energy!
In 1991, wind power cost 15 cents per kilowatt hour. The cost has now dropped to 6.5 cents per kilowatt hour, according to the Lawrence Berkeley National Laboratory, in Berkeley, California. New natural gas power plants are expected to generate electricity at about 6.5 cents per kilowatt hour.
The Electric Reliability Council of Texas said that the latest data on wind turbine performance and costs suggests that wind power is likely to be more cost-effective than natural gas over the next 20 years, and it could account for the majority of new generating capacity added over that that time in Texas.
