How Nuclear Energy is the Hope of Future?
Atomic energy is generated by splitting nuclear substances such as the atoms of uranium, thorium, cheralite, zircomium under controlled conditions.

For conservation of energy resources in India an Energy Conservation Act, 2001 was enacted, which came into effect in March 2002. It provides measures for efficient use of energy and its conservation. To conserve energy we should:
The sources of energy which have been in use for a long time, e.g., coal, petroleum, natural gas and water power.
Until World War II, the world was familiar with only mechanical, chemical, acoustic, thermal, optic, magnetic and electrical forms of energy. But on a fateful day in 1945 when the U.S. exploded atom bomb over Hiroshima, the world got aware of nuclear energy.
We need energy for doing work. Energy is provided by carbohydrates and fats. Carbohydrates and fats on oxidation liberate energy. As compared to fats carbohydrates get easily oxidized…
Flow of energy through the ecosystem is a fundamental process, which can be easily quantified if the energy input to the ecosystem and its subsequent transformation from one tropic level to another can be expressed in terms of calories.
All chemical reactions require some initial input of energy to start the reaction. Similarly, all molecules require certain amount of energy for activation before the chemical reaction. This energy is called activation energy.
A.T.P. i.e., the adenosine triphosphate is known as the energy currency of the cell. In all living cells energy released in exergonic reaction is stored within a chemical compound called A.T.P. The cells deposit extra energy as lipids, glycogen or as carbohydrates.
Solar energy received by the earth is distributed over a large area near the poles than at the equator. Thus, the amount of energy received per unit area is more at the equator, which is consequently much warmer than the poles.
In the beginning steam was used to run the machines. Fire was needed to boil the water to produce steam. Coal and wood were widely used for this work. This was the fuel for big machines.
