US scientists have identified a new source of renewable energy: evaporation. The flow of water vapour into the atmosphere – it happens wherever there is liquid water – could generate up to 325 gigawatts. This is 69% of the nation’s annual electrical generation. The same process could save about 25 trillion gallons of water every year. This is about one fifth of US water consumption. And the same technology could be exploited as a natural battery to conserve renewable energy for those moments when the wind fails to turn the turbines or at night when the solar power plants lie idle.
