Renewable Energy Technology Costs and Drivers
"Provided herein is a preliminary, high-level summary of future and projected cost estimates for 1) Biofuels, 2) Solar (PV & CSP), and 3) Vehicle Batteries. Cost estimates are dependent on various assumptions and can vary substantially. The summary tables in this document present ranges of costs, and a supplemental spreadsheet is provided with sources used to develop these estimates. This document also provides additional information to complement the quantitative data by providing more background information on policy and other drivers impacting current, and projected, costs for these technology sectors. In the final section, two NREL capacity expansion models are discussed as an example of how these and other data are used to develop scenarios of future electricity generation."
