Hydropower has now become the best source of electricity on earth. It is produced due to the energy provided by moving or falling water. History proves that the cost of this electricity remains constant over the year. Because of the many advantages, most of the countries now have hydropower as the source of major electricity producer.
Advantages of hydropower:
The first benefit of the hydropower is that no air or water pollutants are produced. The water used does not contaminate the air or water by producing harmful wastes. No poisonous bi-products are produced. If we compare it to the a nuclear source which produce electricity from a radioactive substance in a nuclear reactor, then we notice that no pollutants are produced from a hydropower source as compared to the nuclear wastes and radioactive rays which are damaging the life on earth. These wastes from nuclear reactors then reach water due to power system and this is how water pollution takes place, not only affecting humans but also aquatic life.
Say no to greenhouse gases
No greenhouse gases like carbon dioxide are produced which makes this source of energy environment-friendly. It prevents us from the danger of global warming.
Saving natural resources
The hydropower does not use any fuel or fossil fuels. The natural balance in an ecosystem is not disturbed. The fossils are non-renewable so their saving is very important to make sure that they do not deplete.
A predictable renewable source of energy
It is a renewable resource as it can be pumped again and again and water is recycled on the earth naturally and artificially both through the water cycle. Water never actually completely depletes. It dominates other renewable resources like wind energy because it has a predictable nature. The forecast can tell us about the rainfall and we can keep ourselves prepared for water collection.
Dams as a water reservoir
Another benefit of dams is that they not only produce electricity but also saves and reserves water so that the water is not wasted into oceans and seas. So it is like two advantages in a single packet.
This source not only assists environment but also the economy. As no fuel is used and we also know that the prices of fossil fuels are raising very high so not much cost in made on the production of electricity. Other than that, no imports are needed to be made which saves money. The cost of this electricity is less than electricity produced from fossil fuels and nuclear power.
Constant source of energy
The prices of fuels keep on increasing on and off. Due to which the cost of electricity also keeps on changing but due to rainfalls the rate of hydroelectricity remains constant somewhat and does not increase much. Hydropower source can lighten the country 24/7 whole year.
Controllable source of energy
The rate of electricity produced can be changed by varying the speed of water flow. The faster it would flow, the more energy it will have to run the turbines. So ultimately turbines convert the comparably greater amount of energy.
So hydropower is sustainable and long-lasting source of energy. It produces a great amount of electricity. Dams can also be used for other purposes like fishing and sports. All these advantages show the importance of hydropower electricity which gives us a solution for the problems of this boom and gloom economy.
