Since 2009, Mark Jacobson, Professor of Civil and Environmental Engineering at Stanford University and Senior Fellow at the Woods Institute for the Environment and Precourt Institute for Energy, and more than 85 coauthors have written a series of peer-reviewed journal articles evaluating the scientific, engineering, and economic potential of transitioning the world’s energy infrastructures to 100% clean, renewable wind, water, and solar (WWS) power for all purposes by 2050, namely electricity, transportation, heating, cooling, and industrial energy uses.
These papers have helped to shift the global conversation around the possibility of completely decarbonizing the world’s energy sector through renewables. They have helped to motivate a wave of 100% renewable energy commitments by over 100 cities and subnational governments, including 35 cities in North America, 100 large international companies, and 48 countries. California, the world’s 6th largest economy, just announced its 100% by 2045 renewable target and proposed U.S. House Resolution HR540, U.S. Senate Resolution SR 632, and U.S. Senate Bill S.987 calling for the United States to go to 100% clean, renewable energy by 2050.
