Stanford engineer Jacobson: U.S. can attain all renewable energy by 2050

San Onofre Safety

Post revised 7/28/2014 to reference Mark Jacobson’s California study, A roadmap for repowering California for all purposes with wind, water, and sunlight, June 2014.

This study presents a roadmap for converting California’s all-purpose (electricity, transportation, heating/cooling, and industry) energy infrastructure to one derived entirely from wind, water, and sunlight (WWS) generating electricity and electrolytic hydrogen. California’s available WWS resources are first evaluated. The plan contemplates all new energy from WWS by 2020, 80 to 85% of existing energy converted by 2030, and 100% by 2050. Electrification plus modest efficiency measures may reduce California’s end-use power demand ~44% and stabilize energy prices since WWS fuel costs are zero. Several methods discussed should help generation to match demand. A complete conversion in California by 2050 is estimated to create ~220,000 more 40-year jobs than lost, eliminate ~12,500 (3800 to 23,200) state air-pollution premature mortalities/yr, avoid $103 (31 to 232) billion/yr in health costs, representing 4.9 (1.5 to 11.2)% of California’s 2012 gross…
