Hydrogen is a much cleaner energy source than CNG. CNG (compressed natural gas) is derived from biomass and hence burning the CNG causes air pollution; albeit on a much smaller scale than coal and petroleum. Use of hydrogen as energy source does not polluting gases.

Many sources of energy can be pollution free. When burning of biomass is not involved in production of energy, then there is no chance of pollution. For example; wind energy, hydel energy, solar energy, etc. are pollution free.

Advantages of nuclear energy are as follows: 1. A small amount of radioactive material can generate a huge amount of energy. 2. It does not produce air pollution. 3. A nuclear power plant is more efficient than other power plants.

Limitations of energy which can be obtained from the oceans: 1. These forms of energy can be harnessed only in coastal areas; which would leave a vast portion of the human habitation. 2. The technologies for harnessing them are still at experimental stage and hence are very costly and less efficientRead more

A concave mirror is best suited for use in a solar cooker. The reason for this is the ability of a concave mirror to converge the solar energy at a point. This enables the concave mirror to produce a larger amount of heat; compared to other types of mirror.

Before the beginning of the Industrial revolution, wind and water energy were used for serving many purposes but the ways of their use were not efficient. For example; windmills were used to power smaller mills; like flour mills or saw mills. The flow of water was used for transporting wooden logs.Read more

For example; windmills were used to power smaller mills; like flour mills or saw mills. The flow of water was used for transporting wooden logs. Now-a-days, both wind energy and water energy are being harnessed to produce electricity which means a better and more efficient use of these forms of energy.
Because of growing population, the energy demand is rising. Fossil fuels are going to be exhausted in the near future and burning them is causing air pollution. Hence, we need to find an alternate source of energy which renewable and environment friendly.

I will use LPG (Liquefied Petroleum Gas) for heating my food; because it is easily available in my kitchen, gives no smoke on burning and takes less time to do the job.
