Could the World be 100% Solar?

40 minutes sun transmission to solar power can fulfill all human energy demands for a year

40 minutes sun transmission to solar power can fulfill all human energy demands for a year

The amount of solar energy that hits just 1 square mile of this planet over the course of a year, is equal to 4 million barrels of oil. 

The energy that hits the Earth in 40 minutes can fuel all of humanity’s energy needs for a year.

If more than a quarter of the electricity is generated directly by the sun, it will reduce the emission of 6 billion tons of CO2! That’s more than the entire emission of the U.S. in 2014.

So it should be possible to run this world 100% green power. Why not take a change?

How much energy does the world need?

3. Concentrated PV Panel – 31.8% efficiency


Many counties don’t have enough land for silicon and concentrated PV panel farms. That’s why thin-film PV cells are the best solution for most counties.

Solar costs

The initial cost of building solar farms is extremely high. However, the US Energy Department aims to reduce the cost of each Watt produced to less than a dollar bij 2020!


Traditional PV Cells are made from silicon. Silicon mining is both costly and environmentally unsound. However, as thin film technology takes over, manufacturing should become more sustainable.

As PV efficiency improves, so will the possibility of a 100% by the sun powered world.

Researchers from the U.S. Department of Energy’s (DOE) SLAC National Accelerator Laboratory and Stanford University have designed a low-cost, long-life battery that could enable green energy from the sun and the wind to become major suppliers
