Secure
Creating a Low-Carbon Future
Revis James Director, Energy Technology Assessment Center October 16, 2009
Critical Conclusions
• With achievement of aggressive but technically feasible levels of technology performance and deployment, annual U.S. electric sector CO2 emissions could be reduced by 41% by 2030. • An optimal technical and economic strategy is comprised of aggressive end-use efficiency and a diverse generation technology portfolio. – Ensures technological resiliency. – Lowers cost of emissions reductions by ~37%. • All technologies not yet ready - focused, sustained research, development and demonstration over the next 20 years is necessary. • Decarbonized electricity will be critical in reducing costs of reducing CO2 emissions from transportation and other economic sectors.
