California’s Energy Future (CEF) was a two-year study sponsored by the California Council on Science and Technology to identify pathways for achieving California’s aggressive greenhouse gas (GHG) reduction target of 80% below the 1990 level in 2050. A summary report was published in May 2011 (CCST, 2011). The analysis first estimated how emissions could be reduced through modifications to demand, including aggressive efficiency and electrification. [Details of the efficiency and electrification calculations are presented in the separate CEF reports on building and industrial efficiency (Greenblatt et al., 2012) and transportation (Yang et al., 2011)]. Second, the analysis looked at various supply technologies for electricity and fuel and how these could be provided without emissions. This report examines electricity generation through fossil fuel combustion with CO2 capture and sequestration (“fossil/CCS”), or renewable energy technologies (wind, solar, geothermal, biomass, hydro, etc.). A separate CEF report describes a nuclear power option; see Richter et al. (2011). Youngs et al. (in preparation) examines meeting the fuel demand with biofuels. A final report synthesizes the results of the other reports, and explores the remaining challenges—and possible solutions—to achieving California’s ambitious GHG target (Greenblatt and Long, 2012).
