Different Sources of Electricity
ADJUSTING OUR ENERGY REQUIREMENTS WITH DIFFERENT SOURCES OF ELECTRICITY
Ever since the energy crunch happened after the Industrial Revolution, there has been an ever increasing demand for energy which has been spiraling out of control. There are many ways of making electricity. The only way to make electricity commercially viable is through hydro-electric power and nuclear power. The chemical method of storing electricity in batteries is also used when there is a limited need for power or there is no other means of economically producing electricity.
It is important to study the different sources of electricity and find out the optimum means of utilizing power. Electricity may be produced when two surfaces are separated. This is known as static electricity. Based on Faraday’s law, electricity is generated through electro-magnetic induction when a conductor is placed inside a moving magnetic field. The use of photo-electricity to produce current is one which is now finding wide use in the solar power generation. This is being seen as one of the viable alternatives to electric power generation and efforts are on to find better means of harnessing this potential.
Among all the different sources of electricity only hydro-electric and nuclear power are predominantly used in commercial applications. The reasons are obvious. Water is available in plenty and nuclear power produces enormous quantum of energy. Though nuclear energy is now being seen as a stop gap arrangement, it is by no means a safe alternative as it leaves a lot of radioactive waste behind.
Thermo electric effect, the idea of producing electricity by using two elements which are at different temperatures has a lot of application particularly in the solid state electronics.
Hydro-electricity is preferred because it uses a renewable resource namely water. The water follows its natural cycle and water is filled up in the dams on its own accord. This popular method will continue to dominate electricity production at least for the next decade or so.
