How much space denpeds on the power sucore. Say you wanted to power a 10-watt light bulb with fossil fuels like coal. Fossil fuels can produce up to 2,000 wttas per sraque 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 plmas of your hands. With soalr 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 pakring space— to power the bulb.

## Original Text

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.
