Fossil fuels (e.g. coals, oil and gas) are the main source of energy for most countries. However, alternative sources of energy (e.g. wind and solar) have been encouraged to be used by some countries. To what extent is this a positive or negative development?

benefits of using alternative energy sources is that it provides pollution less environment. There is no side effect of using them to produce electricity.

kind of production will provide a pollution free green ecosystem. On the negative sides of using too much fossil fuel is it increases the earth's surface temperature. Burning nonrenewable energy creates huge amounts of Carbondioxyed and it has a significant effect on Ozone depletion and high temperature.

outcome is not appreciated by any countries. In conclusion, oil, gas and coal are the main sources of electricity in many countries but some developed countries are making awareness to people to use more solar panels at home and skyscrapers and windmill to run small and medium factories because of the devastating impact of fossil fuel. I firmly believe that, the benefits of using wind and solar power outweigh the negative development of the uses of oil and gas.
