CARSON CITY, Nev. (AP) - Critics say Nevada's largest utility is undercutting the spirit of legislation designed to spur renewable energy development by purchasing power from out-of-state sources.
State law requires NV Energy to produce a certain percent of its electricity from renewable energy.
But the Las Vegas Sun reports the company has used wind power from Wyoming, geothermal from Utah and hydropower from Idaho dams to help it meet the state's requirement.
Environmentalists and renewable energy advocates say NV Energy's purchases, estimated to be as much as $100 million since 2009, have created a surplus of renewable credits and stymied Nevada's green energy efforts.
The Public Utilities Commission of Nevada has upheld the company's short-term purchases.
