    Mark Zachary Jacobson (born 1965) is professor of civil and environmental engineering at Stanford University and director of its Atmosphere and Energy Program....
    ....In 2010, the journal Energy Policy published two papers by Jacobson and Mark A. Delucchi about "Providing all global energy with wind, water, and solar power"....
    .... They estimate that 3,800,000 5 MW wind turbines, 49,000 300 MW concentrated solar plants, 40,000 300 MW solar PV power plants, 1.7 billion 3 kW rooftop PV systems, 5350 100 MW geothermal power plants, and 270 new 1300 MW hydroelectric power plants will be needed. Such a WWS infrastructure reduces world power demand by 30% and requires 0.41% and 0.59% more of the world's land for footprint and spacing, respectively.
