IELTS Task 2 Band 9 Sample Essay

Some people assert that countries should switch to green energy, whereas some others believe that energy production from fossil fuel could be continued if it is economically viable for a country. Despite being harmful to people and environment, some fossil fuel centric establishments might hinder nations from going for green energy, even though this essay believes that renewable energy is the best alternative option in terms of both reduced health risk and less government expenditure.


In recent days, because of burning fossil fuels, air pollution level has increased all time high which is causing various fatal diseases, whereas green energy is neither environmentally harmful nor health hazardous, as it is produced from renewable sources such as wind, water, and sunlight etc. Switching to this technology, nations can prevent a mountainous medical expenditure each year because fewer number of people will fall sick, thanks to the cleaner environment due to green energy technology. As a result, governments can diverse their health fund for other spheres of public needs and eventually bring an overall improved quality of life.


However, though the green energy sources are renewable, they might not be cost effective unless there is a structural setup for harnessing energy from the renewable sources, such as, air, water, Sun etc. In fact, every nation has its customised energy establishments, and they are functional mostly in accordance with the conventional energy production from fossil fuels. Overhauling this whole mechanism overnight might not be a feasible option for all the countries, as it could incur a huge cost that is ultimately born by general people through taxation or other fees. Moreover, some countries have abundant mineral resources, giving them comparative advantage for using fossil fuels in terms of cost. Therefore, for some nations, it might not be viable to drastically switch to green energy sources, at least as long as fossil fuel is their cheaper option.


In conclusion, it appears that fossil fuels are harmful to people and environment, while the green energy can provide many benefits. In my opinion, the better alternative to coals and gas are the renewable energy sources, as it promotes better health and protect the Earth from further damage from fossil fuel usages.
