SOLAR SYSTEM

Detailed explanation-1: -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.

Detailed explanation-2: -The Sun is a huge thermal reactor about 93 million miles away. In heat transfer by radiation, energy is carried by electromagnetic waves from a starting point to the space surrounding it and does not involve contact with matter.

Detailed explanation-3: -The Sun is the major source of energy for Earth’s oceans, atmosphere, land, and biosphere. Averaged over an entire year, approximately 342 watts of solar energy fall upon every square meter of Earth. This is a tremendous amount of energy-44 quadrillion (4.4 x 1016) watts of power to be exact.

Detailed explanation-4: -The sun, like all stars, contains mostly hydrogen. It produces energy from nuclear fusion reactions where Hydrogen is converted to Helium. This fusion reaction occurring inside the sun produces a lot of energy in the form of heat and light.

Detailed explanation-5: -Solar thermal power systems use concentrated solar energy In most types of systems, a heat-transfer fluid is heated and circulated in the receiver and used to produce steam. The steam is converted into mechanical energy in a turbine, which powers a generator to produce electricity.
