Fossil fuels are main sources in many countries. But in some countries the use of alternative sources of energy are encouraged. Is it a positive or negative development?

Nowadays, the scientists are doing their best to invent another source of energy to be friend to our environment. they finally succeded by generating energy, like power, from the sun light. We call it now Solar energy. however, if a country got fossil fuels as a main source of its energy, it should benefit from it as much as possible. In this essay, I will show the negative and positive results of conventional and new source of energy.

One of the positive results of using friend energy to our environment is keeeping the earth nautre without expolitation. For example, to use the solar energy in generating the electricity, we wouldn't need to dig the ground or exploit the farms. What we need is just normal installation of some pipe lines and some huge sun glasses, which absorb the sun lihgt on the ground at most bright area, then installation of boiler to boil the evapour the water. While, it is negative development is to extract the fossil fuel, we have to do many processes including excavating the earth ground and discharge the resulted smoke to the sky and so on.  

in the contrary, whichever country got the fossil fuel, can benefit from it by extract it and export it to other country. One of the advantage here is to serve the increasing of international demand to the oil and to gain lots of money to the exporter country which helps it to develop its infrastructure and improve its economy. Unfortunately, till date, the scientist couldn't invent a source of energy widespreaded and covers the global demnad. The solar energy and other type of energy may cover about 5 percent of the global market demand. this is because of the limitation of their usage.

As a result of the above, I would say that it is a great deal if the human can invent a replacement sourse of energy to be friend to our environment and last long. In the meantime, nuclear and solar energy can be the best replacement if improved by us to cover the whole international demand.
