"Supplies of wind and solar energy on accessible land dwarf the energy consumed 
by people around the globe. The authors’ plan calls for 3.8 million large wind 
turbines, 90,000 solar plants, and numerous geothermal, tidal and rooftop 
photovoltaic installations worldwide. The cost of generating and transmitting 
power would be less than the projected cost per kilowatt-hour for fossil-fuel 
and nuclear power. Shortages of a few specialty materials, along with lack of 
political will, loom as the greatest obstacles."

The authors. Mark Z. Jacobson is professor of civil and environmental 
engineering at Stanford University and director of the Atmosphere/Energy Program 
there. He develops computer models to study the effects of energy technologies 
and their emissions on climate and air pollution. Mark A. Delucchi is a research 
scientist at the Institute of Transportation Studies at the University of 
California, Davis. He focuses on energy, environmental and economic analyses of 
advanced, sustainable transportation fuels, vehicles and systems.
