Energy Resources and Storage

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.

The process of converting the energy of water into electricity is called hydro-electricity.

Thermal electricity is generated by the combustion of fossil fuels, which include coal, oil, and natural gas.

In rural areas of India, a significant portion of the population relies on non-commercial energy sources like firewood, dung cakes, and crop residues for cooking and heating.

Natural gas is a primary energy source in its raw state and acts as a final energy resource when delivered to consumers for heating or cooking. It fits both definitions depending on the stage of the supply chain.

Thermal power, primarily coal-based, accounts for the largest share of electricity generation in India, providing the base load for the country's power grid.

A final energy resource is one that is consumed by the end-user in its final form. Electricity generated in a thermal plant and consumed by an industry is a classic example of final energy consumption.

A primary energy resource is a natural resource that has not been converted or transformed. Coal, when used directly as a fuel, is in its primary state.

Thermal power projects, primarily coal-fired, provide the largest share of power generation in India, making them the dominant source of electricity.

Non-commercial sources of energy are those that are not bought and sold in the market, such as firewood, dung cakes, and agricultural waste, which are typically collected by households.

Coal is a primary energy source because it is a raw material extracted from the earth, whereas electricity is a secondary source derived from primary ones.

Energy which is generated by using wind, tides, solar, geothermal heat, and biomass including farm and animal waste as well as human excreta is known as non-conventional energy. All these sources are renewable or inexhaustible and do not cause environmental pollution. Bio-gas is an example for non-conventional energy. It is based upon the use of dung to produce gas which is used as domestic fuel especially in the rural areas. This technique is based on the decomposition of organic matter in the absence of air to yield gas consisting of methane (55%) and carbon dioxide (45%) which can be used as a source of energy.
