Electricity has a wide usage

By: Ashish K Arora
Electrical energyis produced in generating stations where huge turbines are by moved thegenerators. Then the electricity is transmitted by long distance power lines tothe consumers. Turbines could be started by burning fossil fuels, by water,wind, nuclear fission, bio waste.

By burning fossil fuel: Coal, petroleum or natural gas heat water, thusmaking vapor.This vapor affects the blades of turbines making them to move andproduce electricity. This method of producing electricity causes a lot ofcarbon dioxide to be released into air and atmosphere becomes polluted. Burningfossil fuel can be extremely dangerous because it can cause respiratorydiseases and this becomes a global problem.This is the fact we must thinkabout.

By water: Electricity can also be produced by using waterfrom rivers or lakes. This water goes through water turbines making them togenerate electricity. We must admit this is very popular way of producingelectricity because it doesn’t pollute the environment. But what we have toemphasize, is the fact that it affects the environment in the rivers or lakesseverely.

By wind: Wind energy is used for producing electricity as well. This energy isrenewable energy source because no one can stop wind to blow, it is widelydistributed and very clean.

Another way toproduce electricity is nuclear fission. This is a chain reaction where Uranium atoms are being split apart. In thisreaction energy of atoms change into heat energy which heat water to vapor. Itmoves turbines and generate electricity. When this reaction is not controlledyou can have an atomic bomb and also it creates radioactive material which canhurt people if released.

By bio waste: Bio-waste includes burning food waste, gardenwaste, organic and industrial waste (papers, textiles...). This can reduce useof fossiil fuels, reduce pollution and gas emissions.

We have to thinkwhich method is the best to save our planet from pollution and to save peoplefrom diseases.
