How many solar panels would it take to power the PLANET?
Experts reveal we would need to cover an area the size of Spain to provide the world with enough energy. The calculations were made by Robert Ferry and Elizabeth Monoian from the Land Art Generator Initiative (LAGI)
They used US Department of Energy data about the world consumption of energy with projected figures up to 2030.
From this, they worked out how much energy would be needed per square metre of land across the globe.
Panels would need to cover 191,817 sq miles (496,805 sq km) of land to power the world with solar panels - the equivalent to covering the whole of Spain with the boards.
