But in some countries the use of alternative sources of energy is encouraged. Is it a positive or negative development? In this day and age, many countries look forward the new energy,like solar energy,wind energy and tide energy,to replace fossil fuels. It is manifest that the use of environmentally-friendly energy is a positive progress for the development of human beings. Such new energy to be explored and used can have some profound influences on society. Firstly, the alternative sources of energy are renewable. For example, as we all known, tide energy is a sort of natural resource which scientists are trying to use it to generate electricity, without worrying about the problem of overexploitation. Secondly, most new sources of energy are of environmentally-friendly, which means they are unable to generate harmful and baneful substances. Finally, the price of new energy is much cheaper,because many cutting-edge technologies are utilized to reduce the cost, which can benefit the public. Moreover,people in the globe have realized the drawbacks of using fossil fuels. Carbon dioxide from the use of fossil fuels is the main factor to bring about greenhouse effect, which can lead to global damages. Because of greenhouse gas emissions, according to the recently report,the temperature of the whole year has been raised.In addition, fossil fuels will be used up in the future, so developing alternative sources is a crucial ingredient in order to make sure the growth of human being. In conclusion, it is imperative to develop the alternative sources of energy, no matter for protecting the environment we live in ,or for the development of our offspring. -------------------------------------------------------- Thanks for your correction!
