Study claims 100 percent renewable energy possible by 2030 http://apocadocs.com/s.pl?1295446922
New 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.... Achieving 100 percent renewable energy would mean the building of about four million 5 MW wind turbines, 1.7 billion 3 kW roof-mounted solar photovoltaic systems, and around 90,000 300 MW solar power plants.... Jacobson said the major challenge would be in the interconnection of variable supplies such as wind and solar to enable the different renewable sources to work together to match supply with demands. The more consistent renewable sources of wave and tidal power and geothermal systems would supply less of the energy but their consistency would make the whole system more reliable.
