Fossil fuel is the main source of energy. In some countries, the use of alternative sources of energy is encouraged. To what extent do you think is it a positive or negative development?

　　In several parts of the world, fossil fuel plays a primary role in producing energy. However, governmental leaders also promote the utilization of nontraditional sources of power. I believe that this policy could generate both advantages and shortcomings.

　　There are various benefits of putting renewable power sources into practice. Firstly, when the exploitation of the non-conventional energy sources gains more popularity, followed by a decrease in the utilization of fossil fuel, natural renewable resources, which are being overexploited at an alarming rate and in danger of being exhausted, can be saved with a view to being preserved for later generations. Secondly, non-traditional sources of power like solar energy or wind power are considered to be environmentally friendly. In other words, they may discharge almost no toxic chemical emissions or pollutants. Consequently, the environment can be protected. Finally, factories or corporations generating renewable power can make contributions to supplying more job opportunities for the community and satisfying the increasing requirements for energy for daily social life and industrial production.

　　Nevertheless, in my view, countries can be confronted with several problems when making use of these kinds of energy. In various cases, when nuclear power plants could leak radioactive substances, the community health will be endangered and the living environment may be poisoned. Additionally, national authorities are obliged to allocate a huge amount of state budget for constructing nuclear power factories, installing windmills or purchasing solar panels, followed by a shortage of national fund for other key sectors like educational systems or health services. Another trouble is that on days with little wind or sunlight, wind power or solar energy can hardly be produced. Moreover, in dry seasons, there is nearly no rain, leading to a lack of water for turbines to produce power. All the above mentioned matters may give rise to a deficiency in electricity for community life and manufacturing.

　　In conclusion, I am of the opinion that it is beneficial and problematic for nations to exploit renewable sources of energy.
