Energy

      In fact nothing can live without energy on the surface of the earth. That’s because energy allows living things to move about, grow and develop. Machines as well as people need energy to work. Hence, there are many different forms of energy. The most common one which comes from underground such as ; coal, oil and natural gas. This kind of energy is called fossil fuels and it is non-renewable energy. That’s because it takes millions of years to make or renew it. On the other hand, there are many other forms of energy that is considered renewable. One of these is the wind which was used many centuries ago and are still today to generate electricity. Water and the sun are also renewable sources of energy. From water Egypt gets on a great amount of its electricity and it is called hydroelectric power. Using water, the sun and the wind doesn’t pollute the atmosphere around us. Nowadays there are many other forms of energy as atomic energy and nuclear energy. These two kinds are dangerous and aren’t safe because of their dangerous wastes and badly managed atomic power stations. There is also the geothermal energy that scientists have discovered recently. But as a matter o fact, most of our energy comes from the sun which gives life to everything on the surface of the earth. As a matter of fact, energy is necessary in our life and no one can live without it. So, we should do our best to save it.
