Oil energy is mightily useful. But it is non-renewable and it causes global warming. So people are going for other alternatives. Some of them are:

  • Nuclear energy
  • Solar energy
  • Hydro energy
  • Wave energy
  • Geo-thermal energy
  • Ocean energy
  • Wind energy

Nuclear energy

Nuclear energy is produced from two famous process. They are nuclear fission and nuclear fusion.

Nuclear fission: In nuclear fission, an atomic nucleus of a radioactive element splits by bombardment from an external source, with simultaneous release of large amounts of energy, used for electric power generation

Nuclear fusion: In nuclear fusion, multiple nuclei are joined together to form a single big nucleus. During this, large amount of energy is released. The energy from sun is obtained from the fusion reactions that is taking place in the sun.

 

 

Solar energy

  • The energy that is obtained from the sun is known as solar energy.
  • As we all know, sun the primary source for all the energy.
  • Solar energy is a green energy.
  • It is called so because it does not produce any pollution.
  • Solar cells and batteries are used to store solar energy and use them when sun is not available.
  • They are costlier but they would be helpful in a long run.
  • Nowadays, the use of solar water heaters has increased to some extent.

 

Hydro energy

  • Hydro energy is a clean, renewable and reliable energy source which converts kinetic energy from falling water into electricity, without consuming more water than is produced by nature.
  • Hydro energy is the energy available in either running or falling water or both, which may be harnessed for useful purposes such as irrigation, power houses, saw mills etc.
  • Since ancient times, hydro energy has been used to irrigate the farms and to power mills to grind grains.

 

Wave energy

  • Wave energy is produced when the generators are placed in the surface of the ocean.
  • The energy is mainly used for desalination of salt water (process of removing salt content from the salt water, so as to make it drinkable).
  • Some of the factors that determine the output of wave energy are height of the wave, speed of the wave and the density of the wave.
  • ·This type of energy source also does not produce any pollution.

 

Geothermal energy

  • Geothermal energy is generated from the heat present in the earth.
  • It is a newly found alternative.
  • The temperature of earth increases as we dig deep.
  • Thus the heat of the earth below the surface will be high. This heat is used to vaporize the water. This steam is used to run the turbine.
  • Two pipes will be dig deep into the earth. One pipe is to let the water in. And the other one is to get the steam out.

 

Wind energy

  • The earth receives 1.74 x 1017 watts of power (per hour) from the sun. About one or 2 percent of this energy is converted to wind energy.
  • A windmill is used to produce the electricity. It has many specially designed blades, which rotate when wind strikes them. Which in turn rotates the turbine and hence produces the electricity.
  • Nowadays many people are using wind energy to produce electricity.
  • The kinetic energy of the wind is converted into other forms of energy with the help of the windmill.
