Question

Mentions any two ways by which water can be used to produce hydroelectricity.

Answer 1

Hydroelectricity

1. Hydroelectricity means generating electricity by using hydro (water) power.
2. In hydroelectricity generation, water is directly used to generate energy.

Two ways to produce hydroelectricity

Hydroelectric power plant

1. A dam is constructed near the high altitude river whose water is stored in a reservoir.
2. The reservoir contains the potential energy of the water, which is released on the turbine blade to cause it to revolve by demonstrating water kinetic energy.
3. The rotation of the turbine blade will produce electricity with the help of generator arrangements.

Tidal energy

1. Tides cause the ocean's water to fall and rise due to the moon's gravitational influence.
2. During high tides, water is kept in the reservoir, and when the water flows through the reservoir, a turbine located along the way begins to rotate.
3. During low tides, water flows into the ocean from the reservoir and again rotates the turbine.
4. The turbine connected with the generator will produce electricity, and this type of produce electricity is known as hydroelectricity.
