Mark Jacobson is a Professor at Stanford. He has written several books and co-authored over one hundred research articles. His career has focused on better understanding the problems of air pollution and global warming and on developing large-scale renewable energy solutions to them. He has developed three-dimensional atmosphere-biosphere-ocean computer models to simulate air pollution, weather, climate, and renewable energy. He has also developed roadmaps to transition states and entire countries to 100% Wind Water and Solar (WWS), along with computer models to examine electric grid stability.
