Enough Solar Panels To Power The World

Assuming this power rating we would need to divide 2 75 tw by 350w which gives us the gigantic number of 7 85 billion 7 857 142 857 to be precise panels required.

Enough solar panels to power the world.

For the first time ever solar and wind made up the majority of the world s new power generation marking a seismic shift in how nations get their electricity. It would take 51 4 billion 350w solar panels to power the world. Solar additions last year. Put another way this is the equivalent of a solar power plant that covers 115 625 square miles.

The earth s current energy consumption rate is around 13 5 tw at any given moment including oil gas coal nuclear and hydroelectric. Here we are supposing a panel size of 350w for the calculated size of 18tw of solar plants. A total of 51 42 billion solar panels would be needed to power the entire world on solar energy. How do we arrive at this number.

Consumes about 4 petawatt hours of electricity per year we d need about 13 600 000 acres or 21 250 square miles of solar panels to meet the total electricity requirements of the united states for a year. And europe solar installations have dropped 30 due to pandemic india and china are leading the world in solar power programs by 2024 china s deployment of solar panels will far. By another measure the unpopulated area of the sahara desert is over 9 million km which if covered with solar panels would provide 630 terawatts total power. We receive a staggering 1 74 1017 watts of energy from it.

The current standard size of panels used in a large sized solar plant is easily over 350w. Solar capture areas would have to be distributed over a wide area to avoid the problem of cloudy days or storms or other weather events that would obscure the sun pouring down onto your energy farm.
