Renewable Electricity Futures Study

Renewable Electricity Futures Study

Date: 9/23/2013

A report published by the National Renewable Energy Laboratory, the Renewable Electricity Futures Study (RE Futures), is an initial investigation of the extent to which renewable energy supply can meet the electricity demands of the continental United States over the next several decades. Funded by the Energy Department's Office of Energy Efficiency and Renewable Energy, this study explores the implications and challenges of very high renewable electricity generation levels—from 30% up to 90%, focusing on 80%, of all U.S. electricity generation from renewable technologies—in 2050. At such high levels of renewable electricity generation, the unique characteristics of some renewable resources, specifically geographical distribution and variability and uncertainty in output, pose challenges to the operability of the nation's electric system. The report is divided into four volumes and is available as a series of free downloads.

The accompanying Renewable Electricity Futures Scenario Viewer is now available online.
