Lucas123 writes: While the rest of the nation’s solar power generation hovers around 1%, California clocked in with a record 5% of power coming from utility-grade (1MW or more) solar power sources, according to a report from Mercom Capital Group and the Energy Information Administration. That’s three times the next closest state, Arizona. At the same time, 22 states have yet to deploy even one utility-grade solar power plant, according to the Solar Energy Industry Association. Meanwhile, the rest of the world saw a 14% uptick in solar power installations in 2014 for a total of 54.5GW of capacity, and that figure is expected to grow even faster in 2015. While China still leads the world in new solar capacity, Japan and the U.S. come in as a close second and third, respectively. In the U.S. distributed solar and utility-grade solar installations are soaring as the solar investment tax credit (ITC) is set to expire next year. The U.S. is expected to deploy 8.5GW of new solar capacity in 2015, according to Mercom Capital Group. Read more of this story at Slashdot.
