If industry statistics are to believe, solar and wind energy in the U.S is achieving grid parity with conventional fuel sources.
In some markets, renewable energy is already cheaper than coal and natural gas,CNBC reports.
In places like Great Plains and Southwest, where wind and sunlight are abundant, utility companies are signing power purchase agreements (PPA) at prices below that of natural gas, the report says.
For example, in Texas, Austin Energy signed a 2-year PPA at less than 5 cents a kilowatt-hour. Also, in Oklahoma, American Electric Power tripled the amount of wind power after witnessing low bids for wind last year.
