Chapter 3

Now the world's second hottest topic is the hunt for Alternative Sources of Energy. What do you mean by Alternative Sources of energy? Over use of certain rarely found resources such as petroleum, coal etc has lead to their scarcity. So different sources of energy made from abundantly found resources like solar energy, water energy which are called Alternative Sources of energy. All the cars, trucks and vehicles run on the rare resource-petroleum. Do you know that one car lets out an average of ONE TON of carbon dioxide per year! If you just look around your own town or city, you observe there are about a hundred cars in a town and more than thousands in a city. So if we calculate, all over the world the number of cars will be twice the population of the earth! Assume it is about 12.34 billion cars; imagine the amount of carbon dioxide in the atmosphere and how it damages our earth!!!! Now let us talk about the various sources of energy which are available and how is man trying get energy from each and everything in earth. It is very interesting and so if you want to prove yourself eco-friendly, just keep reading. I have converted all those formal and tough abstract and incomprehensible phrases from your assumingly-boring textbooks to very very simple sentences.

*Hydro electricity: Did you know that we can produce energy from falling water? Not from all falling water but… not your bathroom showers too. This hydro electricity can be produced from very large waterfall and dams only. There are many projects starting in various countries. Let me now tell you how it is done. First a big turbine (the wheel like structures seen in the figure one) is placed under the water force so that the falling water will rotate it while the water rushes down. This turbine will move with enormous producing sparks of electricity. In order to get this electricity, the turbines are connected to wires so that they can store and transport electricity to places which need them. You might wonder whether a source of falling water can produce electricity like our normal current without breakage. Yes! It can! Because water in waterfalls fall continuously! Have you seen the Niagara Falls? How breath taking sight it is really! It water force is enormous! It is very very strong. The Niagara falls are situated between the United States and Canada, bordering them. The other waterfalls like the Angel Falls fall with great force. Angel falls is the highest waterfall in the world.
