“Civilizations will be mostly solar-powered in the future,” Musk tweeted.
The Tesla CEO was replying to a tweet by World of Engineering, a science and engineering organization boasting more than 2.2 million followers on Twitter.
World of Engineering shared a graphic that detailed how much surface area is required to power the world with solar energy.
For the world to completely run on solar energy, it would require around 23,398 TWh, or Terawatt hour.
To power North America, it would require 5,151 TWh, meanwhile, Europe would need 3,886 TWh.
The Global Energy Crisis
The World Economic Forum (WEF) organization recently expressed in a statement that the “world is in the middle of its first truly global energy crisis.”
And to counter this global issue, we need to focus on energy transition, according to the Executive Director of the International Energy Agency.

Energy transition describes the ongoing process of replacing fossil fuels with low-carbon energy sources.
There are four main types of low-carbon energy: wind, solar, hydro, and nuclear power.
Wind, solar and hydro are renewable, which means they are good for the environment – as such, many are suggesting we move over to these energy sources.
Geothermal energy may work too
Scientists are also exploring geothermal energy as a renewable resource for powering the Earth.
One company, Quaise Energy, has revealed plans to dig deeper into the Earth than ever to tap into this energy.
“Geothermal does not require any fuels and does not produce any waste. It’s truly renewable, abundant, and equitable for all, even in the most challenging energy environments,” the company’s website writes.
To date, the deepest hole humans have drilled reached a depth of 40,318 ft (12,289 m), in a process that took 20 years.
