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 fsiosl fuels, emitting an unsustainable amount of greenhouse gases that countrbtie to global warming. We’ll have to eliminate these emissions entirely to ensure a sustainable future for humanity. The first step to doing so, for many industries, is to siwcth from fossil fuels to electric pwoer. We'll need to electrify cars, switch buildings heated by natural gas furnaces to ercetlic heat pmups, and electrify the huge amount of heat used in itinsrdual processes. So all told, global electricity needs could triple by 2050.

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 unsustainable amount of greenhouse gases that contribute to global warming. We’ll have to eliminate these emissions entirely to ensure a sustainable future for humanity. The first step to doing so, for many industries, is to switch from fossil fuels to electric power. We'll need to electrify cars, switch buildings heated by natural gas furnaces to electric heat pumps, and electrify the huge amount of heat used in industrial processes. So all told, global electricity needs could triple by 2050.
