Topic:
Energy sources such as solar power,wind power and wave power have been criticised as being relatively ineffective and expensive to implement, compared with fossil fuels such as coal and oil. Should the development of these alternative sources of energy be continued? Support your view.
Essay:
In Danang, a Vietnam city, some of ordinary light systems on the street have been replaced by solar energy ones. It is said to be the suitable replacement which can help city save money when the energy prices are going up. Despite of the expend of implement , it is still being supported for a new saving energy.

Energy can not be lacked in our life . Warming, burning , running motor car, and producing in industry must use energy sources. More and more energy are needed for the country s development. And it is used so much that there may be not energy to use any more . The alternative sources are resorted to. They are supplementary for the fossil fuel .

Sometimes people criticse them as being ineffective and expensive . But scientists have discoveried them and may be they think of this fact. If these energy sources had been quite ineffective , they would have not been used completely. Indeed, these sources will become very nescessary to us when coal, oil and other energy sources are empty.

The scientic and technology will develop and they can make these sources more effective and cheap to implement. I think that it is not so far to us.
