The National Renewable Energy Laboratory (NREL) Western Wind and Solar Integration Study examines the benefits and challenges of integrating enough wind and solar energy capacity into the grid to produce 35 percent of its electricity by 2017. The study finds that this target is technically feasible and does not necessitate extensive additional infrastructure, but does require key changes to current operational practice.
For additional analysis, see Release of the "Western Wind and Solar Integration Study" by the Stoel Rives Renewable Energy Initiative.
