From the Ted Talk by TED-Ed: How much land does it take to power the world?

Unscramble the Blue Letters


No matter how we make electricity, it takes up space. Electricity from coal reiuqres meins, and plants to burn it and convert the heat into electricity. Nuclear power takes uranium mines, facilities to refine the uranium, a reactor, and a place to sotre the spent fuel safely. Renewable eegnry needs wind turbines or saolr pnelas.

How much spcae depneds on the power source. Say you wanted to power a 10-watt light bulb with fossil fuels like coal. Fossil fules can pcudore up to 2,000 watts per square meter, so it would only take a credit card-sized chunk of land to power the light bulb. With nuclear power, you might only need an area about the size of the palms of your hands. With solar power, you’d need at least 0.3 square meters of land— twice the size of a cafeteria tray. Wind power would take roughly 7 squrae meters— about half the size of a parking space— to power the bulb.

Original Text


No matter how we make electricity, it takes up space. Electricity from coal requires mines, and plants to burn it and convert the heat into electricity. Nuclear power takes uranium mines, facilities to refine the uranium, a reactor, and a place to store the spent fuel safely. Renewable energy needs wind turbines or solar panels.

How much space depends on the power source. Say you wanted to power a 10-watt light bulb with fossil fuels like coal. Fossil fuels can produce up to 2,000 watts per square meter, so it would only take a credit card-sized chunk of land to power the light bulb. With nuclear power, you might only need an area about the size of the palms of your hands. With solar power, you’d need at least 0.3 square meters of land— twice the size of a cafeteria tray. Wind power would take roughly 7 square meters— about half the size of a parking space— to power the bulb.
