How Many Solar Panels Power The World

It would take 51 4 billion 350w solar panels to power the world.
How many solar panels power the world. 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. How do we arrive at this number. By the end of 2019 a cumulative amount of 629 gw of solar power was installed throughout the world. Here we are supposing a panel size of 350w for the calculated size of 18tw of solar plants.
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. We receive a staggering 1 74 10 17 watts of energy from it. A total of 51 42 billion solar panels would be needed to power the entire world on solar energy.
