Renewable Energy Can Supply 80% of US Electricity

Renewable energy can supply 80% of US electricity demand by 2050, concludes a report from the National Renewable Energy Laboratory (NREL), the Renewable Electricity Futures Study (RE Futures). The technology needed is available today and is "more than adequate" combined with a more flexible electric system. That increased electric system flexibility, necessary to balance supply with demand, can be met by a portfolio of flexible conventional generation, grid storage, new transmission, more responsive loads, and changes in power system operations. The abundance and diversity of US renewable energy resources, such as geothermal, solar, wind and wave energy, can support multiple combinations of renewable technologies that result in deep reductions in electric sector greenhouse gas emissions and water use. All regions of the US could contribute substantial renewable electricity...
