Fossil fuel, such as coal, oil and natural gas, is extensively used in many countries which cause harms to the environment. The use of alternative sources of energy, including wind and solar power, however, is being encouraged in many countries. Is this a positive or negative development?

Model Answer 1:
Fossil fuel, though extensively used, is not eco-friendly and its usage comes with huge environmental costs. Considering the global warming and climate change, and the detrimental effects fossil fuels have on the environment and public health, green fuel, such as solar, hydro and wind power, could be the answer to our future energy demand. It is a good thing that many countries have already started using these green power sources.
The demand for fuels is rapidly increasing in many countries with the population rise. It is also associated with the industrialisation and it seems only obvious that oil, coal and natural gas-rich countries would largely use them to take the leverage of their stock of such energy sources. For instance, Russia has natural gas, China and India are rich in coal and the USA and OPEC countries has a huge stockpile of oil. Besides, other developed countries that do not have a huge stock of such fuel, import them from other countries at a considerably cheap price. However, the stock of fossil fuel is limited and would get exhausted at a certain point. So, alternative and green sources, which is renewable, would be the main source of our energy in the future and we should get ready for the time when we will have no new oil or gas stock. Since green energy like wind and solar energy is renewable, their use should be as much encouraged as possible from right now and it is a good thing that the trend has already started.
Alternative sources of power, such as solar and wind power, do not pollute the environment, have lower carbon emission and are eco-friendly. So their use could save the planet from a disaster of global warming which is already visible around us. Wind power and solar power are in use in countries like Denmark, Germany and France and more and more countries are joining the list. We already have an extremely efficient technology to produce solar and wind power and the trend is quite encouraging.
The energy demand is increasing at a fast pace and the stock of fossil fuel is diminishing. So we should turn to alternative green energy sources and share the technology and expertise with all nations so that the transition happens all around the world to save our otherwise dying planet due to climate change and greenhouse effects.
Model Answer 2:
These days, the environment is being severely affected by the excessive use of nonrenewable energy resources, such as petrol, diesel, coal and natural gas. However, eco-friendly and renewable power sources like wind and solar power are being adopted in many countries, and I wholeheartedly think that it is a positive trend.
To begin with, many nations have already made a firm decision to regain the balance of our planet and to achieve that, they have made significant modifications in their system. Firstly, the implementation of windmills and hydroelectric plants are gaining popularity at a rapid pace. This is a secure way of generating electricity that saves the environment and money, and leads the way to a future when clean energy will be predominant in the world. For instance, Croatia is setting an example for its neighbouring countries by generating seventy per cent of its energy from solar power. This is a very positive development that other countries can follow to contribute to make the world green again.
Additionally, the major advantage of utilising these alternative resources is that it greatly reduces the carbon content from the environment and makes the planet more sustainable. Moreover, it is cheaper to produce such clean energy than extracting coal or natural gas which makes these eco-friendly energies affordable to mass people. A recent study by Oxford University reveals that production of solar power is 30% cheaper than that of fossil fuel. This finding again emphasizes how important it is for all nations to opt for renewable energy sources, and how beneficial it is that many countries have already invested in generating clean power.
In conclusion, even though we have harmed our Mother Nature to a great extend by indiscriminately using fossil fuels, some countries have already shown us a better way to produce and use that. It is expected that more countries will invest in alternative sources of energy to make the planet green again and to make energy affordable for all.[Written by – Adarsh Rawat] – Bài viết mẫu IELTS writing band 9 , bài IELTS essays mẫu band 9 , bài viết mẫu ielts band 9 , ielts writing task 2 , học viết ielts writing task 2, học viết ielts, học ielts online , cách viết bài ielts
