Mark Z. Jacobson, Professor of Civil and Environmental Engineering at Stanford University, and director of Stanford’s Atmosphere/Energy Program, discusses his work with sustainable clean energy. As part of his work, he’s developed computer models to study how fossil fuels affect the atmosphere and the weather, which are now used by numerous other researchers in the field. He believes we can achieve all of our energy needs from clean, renewable sources alone such as wind, water and solar power, without depending on fossil fuels at all, and all of his research is focused on achieving that objective.
