alternative sources of energy for people to use. In the past people make fire by cracking two pieces of flint causing sparks against dry tinder or fleece. But now people use technology for their needed. People have used more than 90% of fuels‚ such as oil‚ coal and natural gas to produce electricity. These things are non-renewable. The more we use these fuel it will decreases everyday. So we have to find another way to save it by using renewable energy‚ which

It is vital to switch to renewable sources of energy which draw upon the natural forces on Earth to convert energy to be used for the processes which oil currently powers. The greenhouse effect means that when oil is burnt it releases CFCs into the atmosphere which reflects the heat from the sun back onto Earth.
