Put another way this is the equivalent of a solar power plant that covers 115 625 square miles.
How many solar panels power the world.
By early 2020 the leading country for solar power was china with 208 gw accounting for one third of global installed solar capacity.
We receive a staggering 1 74 10 17 watts of energy from it.
Current solar panels can only capture 20 percent of the sun s energy and to become a viable wide scale source of energy for the world they would need to capture much more than that.
A total of 51 42 billion solar panels would be needed to power the entire world on solar energy.
The us energy information administration s estimation of global energy consumption by 2030 is 678 quadrillion btu 198 721 800 000 000 kilowatt hours simple conversion divided by 400.
Here we are supposing a panel size of 350w for the calculated size of 18tw of solar plants.
How do we arrive at this number.
