Q4. How do windmills generate electricity?
The rotary motion of a windmill is responsible for the production of electricity. As the windmill rotates, it turns the turbine of the electric generator. Windmills can also be used in water-lifting pumps to lift water from a well. Although producing electricity using wind as a source is an environmentally friendly way, this method has its limitations. A single windmill cannot be used to produce electricity for commercial purposes. Large-scale wind energy farms are required for this purpose.
Q5. What are the different types of energies produced from the seas?
Various kinds of energies can be utilized from the sea as well. These include the following:
Tidal Energy: Differences in sea levels during high and low tides are responsible for producing tidal energy.
Wave Energy: Strong winds produce large waves in the sea. The kinetic energy possessed by these waves can be used to generate electricity.
Ocean Thermal Energy: Ocean thermal energy plants utilize the differences in ocean temperature to produce electricity.
