I think that the use of alternative sources of energy (also known in some cases as ‘green’ energy) is a positive trend of development, and indeed their use should be encouraged further. As the demand for energy worldwide is increasing, especially in developing countries, the strains on the existing and already limited resources also increase. To solve this problem, we must consider two issues: how to better use the existing, limited fossil fuel resources and how we can encourage the use of alternative energy sources.

It is universally acknowledged that there is a limitation on the use of fossil fuels, especially coal and oil. Some countries are rich in oil deposits like OPEC, whereas China is rich in coal deposits and Russia in natural gas. Others, such as Japan and Germany, are completely dependent on the import of resources. For all countries – resource rich versus resource poor, alternative energy should be encouraged and utilized to reduce the dependence on fossil fuels as well as to keep the global environment in balance and ‘healthy’.

The only way is to turn to other sources to get energy supply. Wind power and solar power are at present feasible alternatives. France is one country which has the advanced  technology needed to produce extremely efficient solar panels to store energy from the  sun. Both kinds of power can reduce a country’s dependence on fossil fuels. Furthermore, they do not pollute the environment and in turn help keep the ecosystem stable.

While fossil fuel resources are diminishing, the demand for energy continues to increase year on year. It is a positive trend to develop other alternatives to replace these traditional energy resources. Experiences should be shared and promoted , technology shared and exchanged to limit or even reduce the greenhouse effect. If this switch to alternative energy is encouraged early enough, then we may yet avoid the pending energy crisis.(314 words)
