what is growing energy needs
Answers
Answer:
Explanation:
Energy is an essential input for industrial development. Energy is produced from commercial sources like coal, petroleum hydroelectric schemes as well as from non commercial sources like cow dug, fuel wood and agricultural waste.
Energy generation and environmental conservation are the twin issues arising from exploitative interaction of man with natural resources. A 1987 report of the International Energy Agency contains a simple but remarkable statement- “Investment in energy conservation at the margin provides a better return than investment in energy supply”.
That means conservation of a unit of energy is cheaper and environmentally more desirable than generating an additional unit. Actually generation of every additional Kilowatt hour of energy requires an investment of Rs.7000/- to 12,000/- in the form of new energy generation equipments.
Excessive utilization of coal and oil for generation of electricity leads to multiple problems like Global warming and acid rains. Tension in Gulf countries increases because they are the major petroleum supplying countries.
To reduce dependency on coal for generation of electricity, hydroelectricity power stations and nuclear power plants were advocated. Huge dams can contribute significantly to electricity generation but they inundate forests, farm lands and wild life habitats. Entire community of indigenous people becomes homeless. In Harsood in M.P. is a very good example. Its population was displaced due to the construction of a dam on the Narmada River. People who have lived there over generations found themselves to be refugees in their own land.
