Explanation:
Geothermal energy is the type of energy that is not derived from the Sun.
Geothermal Energy:
1. Geothermal energy is the heat energy that is generated and stored within the Earth.
2. It is derived from the natural radioactive decay of minerals present in the Earth's crust and the heat flow from the Earth's core.
3. Geothermal power plants harness this heat energy to generate electricity or heat water for various purposes.
4. The energy is obtained by drilling deep wells into the Earth's crust to access hot water or steam reservoirs.
5. The steam or hot water is then used to power turbines, which generate electricity.
Wind Energy:
1. Wind energy is derived from the Sun's energy.
2. The Sun heats the Earth's surface unevenly, causing air to move and create wind.
3. Wind turbines are used to capture the kinetic energy of the wind and convert it into electrical energy.
4. The spinning blades of the wind turbines drive generators, which produce electricity.
Hydro Power:
1. Hydro power is also derived from the Sun's energy.
2. The Sun's heat causes the evaporation of water from oceans, lakes, and rivers, leading to the formation of clouds.
3. When these clouds condense, they release rain or snow, which then flows down to rivers and streams.
4. Hydroelectric power plants harness the energy of flowing or falling water to generate electricity.
5. The force of the moving water turns the blades of turbines, which in turn drive generators.
Solar Energy:
1. Solar energy is directly derived from the Sun.
2. Photovoltaic (PV) cells or solar panels convert sunlight into electricity.
3. When sunlight hits the solar cells, it excites electrons and generates an electric current.
4. This electricity can be used to power homes, buildings, or stored in batteries for later use.
In conclusion, geothermal energy is the type of energy that is not derived from the Sun, as it is generated from the Earth's internal heat rather than solar radiation. Wind energy, hydro power, and solar energy are all forms of energy that are ultimately derived from the Sun.
