　　Currently, frequent power cut or the drain of oil supply has become a serious problem that concerns us with its damage to not only the environment, but also our efficiency in work and study. Although some people propose to raise the cost of fuel as a solution to this issue, I personally believe that it is not the best way to solve the problem of air pollution.

　　Indeed, increasing the cost of gasoline and electricity can conserve energy to some extents. Considering the higher price of the fuel, more people would reduce their use of private cars or shut down lights and the air-conditioner when leaving home. As a result, the reduced number of cars leads to a decrease in demand to the gasoline and hence makes the use of energy more efficient. However, this solution does not solve the problem completely. Even the price of the gasoline goes up, most people would still choose to pay because fuels are the basic need for them to work and travel. Such necessity is not able to be replaced, and conservative problems would continue to be a problem.

　　For government, exploiting new energy sources, on the other hand, is a better alternative to energy conservation because it is an effective solution that will solve the problem eternally. Cars that are powered by solar energy, for example, do not have to worry about the limited power supply, since it uses a long-lasting and powerful battery to absorb and store the energy from the sunlight and then use this energy to power the cars. According to research conducted by scientists in Japan and China, by holding the transformation rate between solar energy to electricity to 28 percent, the solar energy cars do not have to recharge itself and can keep running under the sun for 18 hours. Based on this, cars driven by solar energy would push the limits of energy to a new level.

　　All in all, I believe raising the cost of the fuel is not the best way to conserve energy, since there are better alternatives for government, such as applying new energy sources and raising public awareness.
