Switching The World To Renewable Energy Will Cost $62 Trillion, But The Payback Would Take Just 6 Years

Mark Jacobson and his colleagues at Stanford University have published a new study in the journal Energy & Environmental Science that claims 145 of the world’s nations could switch to 100% renewable energy in a few years using renewable energy technologies available today. They recommend the world make the switchover by 2035, but in no event later than 2050. Their goal is to have 80% operating on renewable energy by 2030.

The researchers looked at onshore and offshore wind energy, solar power, solar heat, geothermal electricity and heat, hydroelectricity, and small amounts of tidal and wave electricity. Batteries were the most common electricity storage solution, with the team finding that no batteries with more than four hours of storage were necessary.
