Conventional sources of energy

Nonconventionall sources energy of

1. Conventional sources of energy are coal, petroleum, natural gas, hydel power and nuclear power.

1. Non-conventional sources of onergy are solar energy, wind energy, bio gas from biomass.

2. Conventional energy is commercial energy which is available in abundance for consumption of different purposes, like industries, domestic and agriculture etc.

2. These sources of energy are renewable.

3. Except hydel power, sources of conventional energy are exhaustible or non-renewable. However, nuclear energy is long lasting.

3. These sources are in initial stage of development.

4. Fossil fuels like coal, petroleum and natural gas pollute the environment by emitting poisonous gases.

4. These sources are widely distributed particularly energy from sun, wind and biomass.

5. With the rising standard of living use of conventional sources of energy has increased.

5. These are significant sources of energy for future when fossil fuels will exhaust and they will not be available.
