Question

What is known as energy crisis? What are the steps to be taken to solve it?

Answer 1

Energy crisis is due to the increase in population which is accompanied by rapid urbanisation and industrialisation.

Steps to be taken to resolve energy crisis are as follows:

1. Reduce the consumption of fuels: The principal target areas are heating and transportation, which account for about 18% and 25% respectively, of our total energy requirements. The consumption of fuel in these areas can be reduced by proper insulation of existing buildings and design changes in new constructions, improving the fuel economy of automobiles and using more efficient means of transportation.

2. Develop new sources of energy: The energy crisis has prompted the development of alternate energy sources other than the heat available from the combustion of fossil fuels.

Wind Energy:

The harnessing technology of wind energy is simple. The strike of the blowing wind on specially designed blades of a windmill's rotor causes it to rotate. This rotation, which is the mechanical energy, when coupled to a turbine, drives the power generator.

Advantages of wind power: i. Power generation is cheaper.

ii. It is free from pollution and environmental degradation.

iii. Since generation is continuous unlike in diesel power, investment is never idle.
