Question

'energy saved is energy produced'. justify the statement by giving any six measure to conserve the energy resources.

Answer 1

Energy saved is energy generated. We cannot keep on producing non-renewable resources like petrol, diesel and electricity. So the need of the hour is the better utilization of existing resources. Energy depletion has become a global phenomenon at present time. The ever biggest problem that man has to face in near future is the energy crisis. The demand of energy is growing many fold in the form of coal, oil, gas or electricity but the energy sources are becoming scarce and costlier. Nearly 97% of the world’s consumed energy is coming from fossil fuels, coal, petroleum and natural gas. 
Population explosion and use of energy in an uncontrolled manner gradually exhausts the world store of fossil energy. It is estimated that daily 2 million tones of coal and nearly 40 million barrels of oil are consumed only in the United States. The increasing use of fossil fuels and biomass for domestic and industrial purpose, the fast depletion of forest land would one day cause the dark age with no stock of conventional energy even may be in the early part of 21st century. Among the various strategies for meeting energy demand, the efficient use of energy and its conservation emerges as the least cost option. Now it is high time for the conservation or saving of energy, and also for the exploration of alternative non conventional or renewable sources of energy like solar energy, wind power, tidal energy, geo- thermal energy, forest energy and atomic energy for future human consumption.
