Fossil fuel (e.g. coals, oil and gas) are the main sources of energy for most mountries. However, alternative sources of energy (e.g. wild and solar) have been encouraged to be used by some countries. To what extent is this a positive or negative development?

Fossil fuels (e. g. coals, oil and gas) are the principal key of energy in maximum Nations while substitute resources of power (e. g. wind and solar) have been inspired to be utilised by few States. This essay believes that it is a positive development. On the one hand, global warming is increasing day by day because of excessive use of fossil fuels like coals, oil and gas. We usually use fossil fuels in industries, vehicles and households and we are badly dependent on these. But fossil fuels have emitted a huge amount of CO2 which already has affected the environment as a result plants and animal life are in danger. That is why, alternative ways of energy are needed to overcome this situation. On the other hand, wind and solar can be used as the alternative of fossil fuels which are renewable. Currently, some developed countries are generating energy from using wind and solar power. These energies are environmentally friendly and these also generate at low cost. That is why, these sources of power contribute positively to impact on the country's economy. Moreover, wind and solar power will never finish until the end of the globe. That is why, those energy sources can be used again and again. So, other countries should follow these countries which use renewable energies as substitute sources of fossil fuels. Therefore to conclude, above all discussion it is clear that alternative ways of energy are more potential and safer than fossil fuels. Use of renewable energies must be encouraged to balance nature and this writing thinks that it is a positive improvement.
