Renewable Energy Sources

Renewable energy sources are those that can be replenished naturally and are not depleted over time. These sources of energy never get destroyed and can be used indefinitely. The correct answer to the question is option 'B' - renewable energy sources.

Explanation:

Renewable energy sources are derived from natural processes that are constantly occurring in the environment. These sources are considered sustainable because they can be replenished within a relatively short period of time. Unlike non-renewable energy sources, renewable energy sources do not deplete or get destroyed when used.

Examples of Renewable Energy Sources:

1. Solar Energy: Solar energy is derived from the sun's radiation. The sun is an abundant source of energy that will continue to radiate for billions of years. Solar panels harness the sun's energy and convert it into usable electricity.

2. Wind Energy: Wind energy is generated by the movement of air masses caused by temperature differences in the atmosphere. Wind turbines capture the kinetic energy of the wind and convert it into electrical energy. As long as the wind blows, wind energy can be harnessed.

3. Hydroelectric Energy: Hydroelectric energy is generated by the flow of water, typically in rivers or dams. Water turbines convert the kinetic energy of flowing or falling water into electricity. As long as the water cycle continues, hydroelectric power can be produced.

4. Geothermal Energy: Geothermal energy is derived from the heat stored within the Earth's core. This heat can be harnessed through geothermal power plants or geothermal heat pumps. As long as the Earth's heat remains, geothermal energy can be utilized.

5. Biomass Energy: Biomass energy is derived from organic matter such as plants or waste materials. Biomass can be burned to produce heat or converted into biofuels. As long as plants and waste continue to grow and decompose, biomass energy can be generated.

Conclusion:

Renewable energy sources are a sustainable and environmentally-friendly alternative to non-renewable energy sources. These sources of energy never get destroyed and can be used indefinitely. By harnessing renewable energy, we can reduce our dependence on fossil fuels and mitigate the negative impacts of climate change.

Renewable sources of energy are inexhaustible and can be replenished in a short duration of time.
