Question

Explain the following sentences.
a. Energy obtained from fossil fuels is not green energy.
b. Saving energy is the need of the hour.

Answer 1

a. Fossil fuels are non renewable sources of energy. These are getting depleted rapidly. Also, the usage of the fossil fuels for energy generation adversely impacts the environment and living beings. Burning of fossil fuels like coal, natural gas etc. leads to emission of gases and soot particles in the environment which pollute the air and cause many respiratory diseases. For example, incomplete combustion of some fossil fuels leads to formation carbon monoxide which affects the health of living beings. Also, burning of fossil fuels releases carbon dioxide in the environment which is the main greenhouse gas. Thus, it can be said that energy obtained from fossil fuels is not green energy.

b. Yes, certainly energy conservation has become the need of the hour. We know our day to day life runs on electricity. Be it fans, lights, televisions, escalators, vehicles on roads or water supply to our homes, each and everything requires energy- "The Electrical Energy" for its working. Even the technology advancement has made it possible to supply electricity to most remote places. Thus, to produce such huge amount of electrical energy, we are getting more and more dependent on non-renewable sources of energy such as coal, petroleum, etc. It is observed that the rate at which these fuels are consumed is much greater than at which it is produced. So, if it continues like this, a day will come when we would get deprived of these sources of energy and thus will not even get the basic amenities of life. So, take a pledge to not waste energy wherever possible for the betterment of our and future generation.
