5. list the common energy sources and describe how to conserve them.

Listed

Explanation:

Five common energy sources are

1. Coal and Petroleum

2. Nuclear energy

3. Geothermal power

4. Solar

5. Wind

conservation of energy is very important in current situation of energy crisis. Efficient utilization of energy sources must be one of the top priority of nations.

1. Procurement of alternate sources of energies to reduce dependence on convectional sources of energies.

2.vehicle running on electric and hydrogen fuels should developed so that sources of coal and petroleum are conserved.

3. Production of solar and wind energies should be on large scale so that their cost become cheaper and available for common people
