The state of Texas has attained their goal of getting 10,000 megawatts of renewable energy capacity this year. The best news is that the goal has been attained fifteen years earlier than scheduled.

According to a report filed with the Electric Reliability Council of Texas last week, Texas has 10,367 megawatts of renewable energy capacity, and generated 21,594,278 megawatt-hours of clean electricity in 2009.

99% of those megawatts come from wind power. West Texas has some of the country’s best wind resources, and has seen a burst of wind power development since ERCOT’s renewable energy program was signed into law by then-Governor George W. Bush in 1999.
