The environment has become a big issue around the whole world. During the last decade, it started to change quickly. The earth is becoming warmer and because of that, there are a lot of natural problems and disasters around the world.
People on earth caused this change in temperature. Further, people need energy in their daily lives. They need electricity, fire, hot water, heating and cooling. To produce energy that is enough for all of these activities, we need fossil fuels and coal. All the countries around the world use these two fuels to make electricity and to heat water or air. Many rich countries depend on countries in the Middle East to give them fossil fuels like oil and gas to be able to serve their people. Countries around the world have been using these forms of energy production almost for a hundred years now. The people on earth are increasing every day, and their needs of energy are also increasing. The price of making energy in the old ways is also becoming higher and higher. In the past, the effects of the use of fossil fuels and coal were not known. However, we now know what we are doing to our world and to our future generations. Therefore, we have to do something to change this. Many countries and governments have started to look for new technologies for energy production. These new energy technologies should be good for the environment. They should not make our problem worse and they should be cheap. One of the new energy technologies is solar energy. In this technology, the sun light is used to produce electricity. Although this field is new, countries are encouraging people and companies to use it. ...
