In modern society, an increasing number of people pay more attention to how to make use of alternative sources of energy effectively.With the development of economy and society, existing energy sources have been hard to meet the increasing market demands. Therefore, alternative energies become more and more important because they are directly related to the future economic and social development. Therefore, this essay will discuss how to harness alternative sources of energy effectively, with a particular focus on some exciting problems of energy, the use of renewable energy, scientific support and government participation.
It cannot be denied that there are many problems with exciting energy sources.Firstly, exciting energy sources will run out, such as coal and oil. So,there are not sufficient energy sources to meet current and future needs of development. Moreover,our development is overly depend on fossil fuel so that considerable problems, have deeply affected environment. For example, massive emissions of carbon dioxide by industry and transport has already changed atmosphere structure and result in serious greenhouse effect.Besides, ozone layer depletion and acid rain also seriously damage our environment and ecosystems. In a word, exciting energy sources have many problems so that the effective development of alternative energy sources become imperative for economic and social development.
It is clear that in order to harness alternative sources of energy effectively, we need to improve productive efficiency of energy by means of develop renewable energy. Under current conditions, developing renewable energy is a necessary and feasible measure for the energy shortfall. Most renewable energies are clean and efficient.Therefore,they benefit improving productive efficiency of energy and make up the shortage of traditional fuel, whilst protect environment.For example, biogas, which is made
