The importance of the green energy It is very important everybody understand about the importance of the green energies. We are very used to oil, coal and gas. But all that produced pollution and the greenhouse effect. So we need use the green energies right now. The green energy is cheap like the sun. In the tropic the sun shine a lot of days at year. The technology to produced electricity with the sun energy exist since a lot of years but is not very popular. Why? maybe because very powerful people control the oil and they don't want lose their business. But the change is own responsibility. We can't hope the governments of the world fix all, we have to do it ourselves.
