write a speech on energy saved is energy generated
Answers
Answer:
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.
Energy conservation is the most economical solution to shortages. Energy conservation reduces energy consumption and energy demand per capita. It refers to the preservation and maintenance of natural resources like water, soil, forest and mineral oil to meet human needs with proper care given to aesthetics and recreations too. The term conservation is derived from two Latin words “con” means together and “servare” to guard; thus conservation means “to keep together” or “to guard together”.
The imposition of an oil embargo on the United States and the price hikes of petroleum by (OPEC) Organization of Petroleum Exporting Countries in1973 ushered an era of economic decline for western countries, leading to recessions and soaring inflation which resulted in growing interest in energy conservation and alternative sources of energy. But, unfortunately even solar energy proved impractical for most large scale applications. The high cost of solar energy, its collection, conversion into electricity and storage has limited the use of solar energy to some extent. Nevertheless researchers are experimenting over a scheme of establishing satellite solar power stations to supply power to earth. Further safety and environmental considerations slowed the use of nuclear or atomic energy as an alternative power source. Thus, some important factors like limitation of fossil energy, increasing demand per capita for energy consumption, economic constrains to meet the cost of energy production, environmental stress due to unplanned energy exploitation and lastly, the dangerous after effects in the application of atomic energy have motivated the entire humanity to think of energy conservation. Conservation of energy is essential to compensate the scarcity of energy and to save the human civilization from disaster.
