Answer :

Final answer:

The Sun, through nuclear fusion, is the primary source of energy, including solar energy. Its massive energy output drives Earth's climate and serves as a model for sustainable energy generation.


Explanation:

The Sun is the ultimate source of energy in our solar system. It continuously radiates heat and light essential for life on Earth. The Sun's energy originates from nuclear fusion, specifically the conversion of hydrogen into helium, releasing vast amounts of energy.

Solar energy is a key renewable energy source harnessed from the Sun through technologies like solar panels, biofuels, wind energy, and hydroenergy. Solar energy is abundant, clean, and sustainable, making it an ideal energy source for various applications.

The Sun's immense energy output of about 4 × 10^26 watts, brighter than a trillion cities with a trillion light bulbs, underscores its significance as a dominant energy source, shaping not just Earth's climate but also serving as a model for energy generation on a massive scale.
