Question

Explain briefly why sun is said to be ultimate source of energy?​

Answer 1

Below mentioned are the reasons why Sun is said to be ultimate source of energy -

Explanation:

• The Sun is an extremely powerful energy source, and sunlight is by far the largest source of energy received by Earth, but its intensity at Earth’s surface is actually quite low.

• It radiates light and heat, or solar energy, which makes it possible for life to exist on Earth.

• Plants need sunlight to grow. Animals, including humans, need plants for food and the oxygen they produce.

• Without heat from the sun, Earth would freeze. There would be no winds, ocean currents, or clouds to transport water.

• Solar energy has existed as long as the sun—about 5 billion years.

• Solar techniques, such as crop rotation, increased harvests. Drying food using sun and wind prevented crops from spoiling.
