Fossil fuels are main sources in many countries. But in some countries the use of alternative sources of energy are encouraged. Is it a positive or negative development?

Since last century, fossil fuels has been an indispensable role in human’s development. However, there must be a day in future when fossil fuels is exhausted. Using substitutes, new energies, is a positive and correct way to deal with that problem and ensure our offspring survival.

Actively exploring and using new energy is a preventive means to cope with many problems. First, some new energy can effectively reduce environmental deterioration except for solving oil crisis. For example, new hybrid or battery powered vehicles can reduce emission, which benefits to relieve greenhouse effects. This is a double-win. Secondly, fossil fuels is not a kind of endless resource and human don’t have technologies to reproduce fossil fuels in a short time. It is because fossil fuels is an evolved outcome in millions of years under the ground. In other word, it is natural power, not man made. Therefore, developing new energy is the only correct way to maintain human’s survival.

Exploring new energies cost much more and some applied alternatives are of danger. We should carry a scientific and reasonable way to use new energy instead of pure encouragement. For example, an electricity plant with wind or nuclear energy need times of initial outlay compared with traditional technology although this make people reduce reliance on oil power. More seriously, if not being proper used or without capacity of control, nuclear can lead to fatal disaster to human. Hence, any encouragement should not exceed capability. 

In conclusion, developing substitutes and using matured new energy technologies are positive and forward-looking attitude to deal with sustainable survival. As long as this development is scientific and prudent, using alternative should be encouraged.
