SOURCE OF ENERGY

Source of energy:

Since electric power is produced by energy available in different forms in nature, it is desirable

Search various energy sources. These energy sources are:

(1) Sun       (ii) Wind      (iii) Water      (iv) Fuel        (v) Nuclear energy.

Of these sources, solar and wind energy have not been widely used because of

At present, the other three sources of water, fuel and nuclear power are

It is used mainly for electric power generation.

(1) Sun:

                 The Sun is the primary source of energy. The energy can be radiated by the sun They focus on a small area with reflectors. This heat can be used to raise steam Electric power can be produced with the aid of a set of turbine switches.

 But this method has limited application due to:

      (a) Requires a large area to generate even a small amount of electricity

      (b) Cannot be used on cloudy days or at night

      (j) It is uneconomical.

                Nevertheless, there are some locations in the world where very strong solar radiation is received These sites are receiving more attention Building solar plants.

(2) Wind:

               This method can be used where air flows for a considerable period of time. And the wind power is used to power the windmill that runs a small generator Electric power from a windmill that runs continuously, the generator is arranged to charge the batteries. And these batteries provide energy when the wind stops. This method has the advantages that the costs of maintenance and power generation are negligible, 

   But the flaws of this method are:

      (a) variable output, 

      (b) unreliable due to uncertainties in wind pressure and 

      (c) generation Very small.

(3) Water: 

               When water is stored in an appropriate place, it has potential energy because of The head was created. This water energy can be converted to mechanical energy with the help of water Turbines. It turns a water turbine, which turns mechanical energy into electricity This method of generating electricity has become very popular because of its depreciation production and maintenance costs.

(4) Fuel: 

               The main energy sources are solid fuels such as coal and liquid fuels such as oil and gas

fuel as a natural gas. The thermal energy of these types of fuels is converted to appropriate mechanical energy The main engines, such as steam engines, steam turbines, internal combustion engines, etc. A prime number A mobile switch operates a switch that converts mechanical energy into electrical energy. Despite the fuel It continues to enjoy its primary source of electricity, but so does its reserves

is decreasing by the day. So, the current trend is the exploitation of hydropower which is increasing or increasing Never mind that it is a constant source of strength.

(5) Nuclear energy: 

              Towards the end of the Second World War, it was discovered that a large quantity Thermal energy is liberated by fission of uranium and other fissile material. Estimated heat produced at 1 kg of nuclear fuel is equivalent to 4,500 tons of coal produced It can be used because of nuclear fission to raise energy through appropriate arrangements. Steam You can run a steam turbine that can, in turn, pay the switch to produce electricity, there are some difficulties in the use of nuclear energy. The fundamentals are

        (a) the high cost of nuclear materials

        (b) The problem of radioactive waste disposal and the lack of personnel trained to deal with the plant.
