In addition to sunlight that hits the earth’s surface every hour with 430 quintillion joules of energy–enough to power the world for a year, new analysis by the International Energy Agency (IEA) finds that if windfarms are built across all useable sites which are no further than 60km (37 miles) off the coast, and where coastal waters are no deeper than 60 metres, they can generate 36,000 terawatt-hours of renewable electricity a year, enough to easily meet the current global demand for electricity of 23,000 terawatt-hours. See: Offshore windfarms ‘can provide more electricity than the world needs’ Supplies from turbines will prove to be the next great energy revolution, IEA predicts.
Economical battery storage was the missing link to back up intermittent power sources, but technological advancements and battery costs that have fallen 80% over the past decade, mean storage is no longer an impediment to a fully renewable power grid.
