Sagot :

173,000 because that’s the amount of energy that continuously strikes earth

D. 173,000 terawatts

  • Solar energy is radiant light and heat from the Sun that is harnessed using a range of technologies.
  • The Earth receives ≈174 petawatts (PW) of incoming solar radiation (insolation) at the upper atmosphere
  • Approximately 30% is reflected back to space while the rest is absorbed by clouds, oceans and land masses.
  • The spectrum of solar light at the Earth's surface is mostly spread across the visible and near-infrared ranges with a small part in the near-ultraviolet.

Since, 1PW=1000TW

Thus, 174 PW= 174*1000=174,000 TW.

Therefore, correct option is D.
