D. Dowd Muska of the Southwest Public Policy Institute writes about solar power in his region of the country:

In 2012, an audit by the Government Accountability Office found that federal agencies have overseen hundreds of “initiatives that support solar energy across the four key federal roles”: R&D; “fleets and facilities,” “commercialization and deployment,” and “regulation, permitting, and compliance.” For decades, wildly generous tax credits have been offered at the federal and state levels. And in the late 1990s, lawmakers began to adopt renewable portfolio standards, which required power suppliers to generate or purchase “green” electricity. In Arizona, 15 percent of power must satisfy these standards by 2025. In Nevada, the rule is 50 percent by 2030. And in New Mexico, all electricity is mandated to be “zero carbon” by 2045.
