Aurinkosähkö: 0.2 % maapallon maapinta-alasta riittää kattamaan kaiken sähkönkulutuksen

The UK would need to cover 12% of its land with solar panels to be entirely powered by the renewable energy resource. That’s according to price comparison site finder.com, which reveals 87% of countries around the world could fully supply themselves with solar power using less than 5% of their total landmass.
The organisation suggests the UK would need more panels due to its relatively high 327GW consumption and its more limited access to sunlight – in total, panels would need to cover around 29,690 square kilometres.
IIt shows there are only three countries around the world needing more solar panel capacity than they have land, namely Singapore at 830%, Hong Kong at 213% and Bahrain at 156%. This is due to Singapore and Hong Kong being two of the most urbanised places in the world and Bahrain’s small surface area being very densely populated.
The study estimates in total, an area measuring around 1.1 million square kilometres (km2) of solar panels would be needed to power global electricity demand.  [emp]
Tämä on kuitenkin vain 0.22 % maapallon maapinta-alasta 510 miljoonaa km2.
