Transitioning world energy for all purposes to stable electricity powered by 100% wind, water, and sunlight

Presented By Mark Jacobson


Global warming, air pollution, and energy insecurity are three of the most significant problems facing the world today. This talk discusses the development of technical and economic roadmaps to convert the energy infrastructures of each of the 50 United States and 139 countries of the world to those powered by 100% wind, water, and sunlight (WWS) for all purposes, namely electricity, transportation, industry, and heating/cooling, after energy efficiency measures have been accounted for. Results showing the ability of the grid to remain stable in each of 20 world regions at low cost under 100% WWS conditions are also discussed. Aside from mitigating global warming, these roadmaps have potential to eliminate 4-7 million air pollution deaths annually, stabilize energy prices, reduce catastrophic risk, and reduce international conflict over energy.
