From the Ted Talk by TED-Ed: How much electricity does it take to power the world?
Unscramble the Blue Letters
That number isn't the complete picture. We'll also have to use electricity in completely new ways. Right now, we power a lot of things by burning fossil fuels, emitting an uaalntnsuisbe aoumnt of greenhouse gases that contribute to global warming. We’ll have to eliminate these emissions entirely to ensure a sustainable future for hmatuniy. The first step to doing so, for many industries, is to switch from fossil fuels to electric power. We'll need to electrify cars, scwtih buildings heated by natuarl gas fuceanrs to electric heat pumps, and electrify the huge amount of heat used in iuidarntsl processes. So all told, goblal electricity needs could triple by 2050.
