Many countries use fossil fuels such as coal or oil as the main source of energy. However in some countries the use of alternative sources of energy is encouraged. Do you think this is a positive or negative development?

In recent decades, the investment of alternative energy sources has been receiving a great deal of public attention in some nations. Although this trend is not without disadvantages, I strongly believe the upsides will justify these.

On the one hand, there are some certainly negative consequences of utilization of alternative energy. One drawback is that the capital-intensive technologies which exploit alternative sources of energy remain prohibitively expensive. This means that they are not the ideal option for small-sized companies and households in developing countries such as Vietnam. Another disadvantage is probably the issue of safety. Take nuclear power as an obvious example to support this idea. Nuclear energy is criticized for its potential to pollute environment, and incidents such as the nuclear disaster following by a major earthquake in Japan remind the public of the dangers of nuclear plants. The poisonous and radioactive emissions produced by the explosion not only killed thousands of people but also ravage the environment there.

On the other hand, there are a myriad of benefits that exploiting alternative energy could offer to us in lieu of the burning of fossil fuels such as coal or oil. First, renewable power sources are eco-friendly and emit low or zero carbon dioxide, which is responsible for the global warming, climate change and degradation of air quality. By increasing in use of alternative energy, these problems can be efficiently tackled. Second, green power sources could offer a sustainable and stable energy supply in the long term. In fact, since fossil fuels are finite, the use of alternative forms of energy will guarantee a limitless supply of power for the future generations.

In conclusion, I would argue that it is essential for governments to allocate more resources to support the use of alternative energy.

You must be careful not to contradict yourself. Give more specific examples.
