UNIT 13




ENERGY


Hello, my friends!! Do you remember? Of course you don’t remember because I don’t tell you yet. Earth need five elements to live.. I mean for life. They are land, fire, water, air and sun. the last element is not from the Earth. The sun is in the outer space. The sun gives us energy, indirectly or directly. The sun can make elctrical energy. The sun also makes another energy indirectly.

Do you remember about coal? The coal was formed by vegetation which died million of years ago but it needed certain (condition) Situation. You know that vegetation grows with the aid of sunlight. When we burn the coal, we will get the energy from the sun indirectly. You know that petrol was formed from the animals were pressed under the rocks in the Earth million years ago. The animals grow  because they eat plants and another animals. The plants get the energy from the (burning) sun. it mean petrol can make the energy because it gets energy from the sun indirectly.

We know that coal and petrol need a lot of time to be formed. So, we have to save our energy. If we don’t do that, we will lose our energy. Nowdays, the scientists try to find another energy (source). They can make electrical energy from the waterfall power, winf power (Energy), vapour power  (energy) and nuclear power (potential). All of these powers also make energy with the aid of the (shining) sunlight. OK, its enough (for now)! I want to finish this writing instantly.
