Hydel energy's contribution to India's total generation capacity is typically cited around 15%.

Energy sources in India are broadly classified into commercial and non-commercial categories based on their availability and marketability. Commercial sources are bought and sold in the market, while non-commercial sources are typically gathered.

Commercial energy sources are those that are traded in the market, such as coal, oil, gas, and electricity generated from water (hydro). Firewood, dung cakes, and agricultural waste are traditional, non-commercial sources.

Firewood is a traditional, non-commercial source of energy because it is often collected rather than purchased in a formal market. Gas, oil, and radioactive elements are standard commercial energy sources.

Atomic energy is generated through nuclear fission or fusion processes involving radioactive elements like uranium, thorium, or plutonium.

Hydro-electricity is generated by using the kinetic energy of flowing or falling water to turn turbines.

Non-commercial energy sources are those that are generally not traded in the market and are collected by users. Firewood, dung cakes, and agricultural waste all fall into this category.

Thermal electricity is produced by burning fossil fuels like coal, oil, or natural gas to heat water into steam, which then drives a turbine.

Commercial sources are those that are available for purchase in the market. Water (for hydro), coal, oil, and gas are all primary inputs for commercial electricity generation.

Electricity derived from the potential or kinetic energy of water is specifically termed hydro-electricity.
