Study claims 100 percent renewable energy possible by 2030.
-- TomNew research has shown that it is possible and affordable for the world to achieve 100 percent renewable energy by 2030, if there is the political will to strive for this goal.
Delucchi and colleague Mark Jacobson left all fossil fuel sources of energy out of their calculations and concentrated only on wind, solar, waves and geothermal sources. Fossil fuels currently provide over 80 percent of the worlds energy supply. They also left out biomass, currently the most widely used renewable energy source, because of concerns about pollution and land-use issues. Their calculations also left out nuclear power generation, which currently supplies around six percent of the worlds electricity.
