Best answer
Correct Answer - Option 4 : A

The correct answer is  Kinetic energy to electrical energy.

  • Hydropower changes Kinetic energy to electrical energy.
    • Hydropower is a clean, renewable, and environmentally friendly source of energy.
    • It produces 3930 (TW. h).
    • On the one hand, as an important renewable energy resource, hydropower contributes significantly to the avoidance of greenhouse gas (GHG) emissions and to the mitigation of global warming.
  •  Hence, option 4 is correct.

  • Hydropower is fueled by water, so it's a clean fuel source, meaning it won't pollute the air like power plants that burn fossil fuels, such as coal or natural gas.
    • Because hydropower plants can generate power to the grid immediately, they provide essential back-up power during major electricity outages or disruptions.
  • Hydropower generators do not directly emit air pollutants
  • Dams, reservoirs, and the operation of hydroelectric generators can affect the environment.
    • A dam and reservoir can also change natural water temperatures, water chemistry, river flow characteristics, and silt loads.
