The correct answer is: D. Non-conventional
HAREDA stands for Haryana Renewable Energy Development Agency. It is a nodal agency for developing energy through non-conventional sources such as solar, wind, biomass, and small hydro.
Coal is a conventional source of energy. It is a fossil fuel that is formed from the remains of ancient plants and animals. Coal is used to generate electricity, produce steel, and make other products.
Nuclear sources are also conventional sources of energy. Nuclear power plants use uranium to generate electricity. Nuclear power is a clean and efficient source of energy, but it is also controversial because of the risk of accidents.
Hydel power is a type of renewable energy that uses the power of moving water to generate electricity. Hydel power plants are built on rivers and dams. Hydel power is a clean and efficient source of energy, but it can have a negative impact on the environment.
Non-conventional sources of energy are those that are not as widely used as conventional sources such as coal, nuclear, and hydro. Non-conventional sources of energy include solar, wind, biomass, and geothermal. Non-conventional sources of energy are becoming increasingly important as the world looks for ways to reduce its reliance on fossil fuels.
