risks and benefits of nuclear power

The energy produced due to the 'fission of nuclei' of certain heavier elements (such uranium), or by the 'fusion of nuclei' of lighter elements (such as hydrogen), is called nuclear energy . Nuclear reactions generate very large and powerful amounts of energy. They ca..

Though the energy liberated per fusion is smaller that that liberated per fission of U-235 (which is about 200 MeV). Yet the hydrogen bomb is much more powerful than the atomic bomb for the following reasons: i) Mass per atom of deuterium as well as tritium is much smaller than that of ur..

Tidal Power - The tides are formed due to the gravitational force of attraction between the earth, sun and moon. During high tides sea water is trapped in a reservoir, and released later to drive turbines, which in turn produces electricity. The block diagram given below illustrates the t..

Summary - Today most of our energy needs are supplied by the fossil fuels. In one hundred years coal will be the only one left as petroleum products may remain only for 3 to 4 decades. Little of stored energy will be left if we continue to use energy at the same rate. Fossil fuels are non-renewable..

Nuclear Energy and Chemical Energy - Nuclear energy is released when very small particles of matter split or combine. After the split or combination, they result in small particles or heavy particle. The rest of the mass is changed into energy. This process of changing mass into..
