Answer 1

$\huge\sf{\red{\underline{\underline{Answer:-}}}}$

(i) Solar Energy:-

• Solar power is energy from the sun that is converted into thermal or electrical energy.
• Solar technologies can harness this energy for a variety of uses, including generating electricity and heating water for domestic, commercial, or industrial use.

(ii) Wind Energy:-

• Wind energy describes the process by which wind is used to generate electricity.
• Wind turbines convert the kinetic energy in the wind into mechanical power.
• A generator can convert mechanical power into electricity.
• Mechanical power can also be utilized directly for specific tasks such as pumping water.

(iii) Hydroelectricity:-

• Hydroelectricity is electricity made by generators that are pushed by the movement of water.
• It is usually made with dams that block a river to make a reservoir or collect water that is pumped there.
• This causes the turbine to turn, which turns a generator which makes electricity.

(iv) Tidal Energy:-

• Tidal energy is a renewable energy powered by the natural rise and fall of ocean tides and currents.
• Some of these technologies include turbines and paddles.
• Tidal energy is produced by the surge of ocean waters during the rise and fall of tides.
• Tidal energy is a renewable source of energy.

(v) Nuclear Energy:-

• Nuclear energy is energy in the nucleus (core) of an atom.
• Atoms are tiny particles that make up every object in the universe.
• In nuclear fission, atoms are split apart to form smaller atoms, releasing energy.
• Nuclear power plants use nuclear fission to produce electricity.
