  • How much solar energy is absorbed and reflected by the Earth?

  • Thus, about 71 percent of the total incoming solar energy is absorbed by the Earth system. Of the 340 watts per square meter of solar energy that falls on the Earth, 29% is reflected back into space, primarily by clouds, but also by other bright surfaces and the atmosphere itself.

  • How do deserts cool the Earth?

  • 鈥淒eserts are heat producers, reflecting around 60% to 70% of the solar energy that falls on them straight back into the atmosphere.鈥?Deserts reflect sunlight through the atmosphere TO SPACE, where it is lost from the atmosphere. Thus deserts cool the planet. Sunlight is transmitted through the atmosphere, not absorbed.

  • How does solar energy affect the Earth?

  • Solar energy warms the Earth, causes wind and weather, and sustains plant and animal life. The energy, heat, and light from the sun flow away in the form of electromagnetic radiation (EMR).

  • What are the disadvantages of solar power in the desert?

  • The construction of PV plants in deserts 鈥?if improperly carried out 鈥?may lead to the destruction of these limited refuges. There have also been reported cases of birds being burnt to death midair when flying through the enormously hot and invisible concentrated sunlight areas over the heliostats of CSP power plants.
