Researchers from Stanford have a plan to get all 50 U.S. states
operating on 100% renewable energy by 2050. They think that that's completely
possible with existing technology, however it will require huge shift from business
as usual for the energy sector.
Professor Jacobson and the team figured out how
each state could use a combination of renewable energy sources using current
technologies like wind, solar, geothermal, and hydroelectric, to keep the grid
running. The specific mix for each state was determined by analyzing sun
exposure, consulting wind maps, and weighing the cost and benefits of other
types of energy like geothermal. The plan comes at huge upfront cost, but because
resources like sunlight and wind are free, the cost will even out after a few
years and be roughly equal to the existing fossil fuel-driven industry. Read more at http://www.businessinsider.com/
