Many countries use fossil fuels such as coal or oil as the main sources of energy. However, in some countries the use of alternative sources of energy is encouraged.Do you think this a positive or negative development?

As a result
of the environmental problems which have resulted from traditional dependence on fossil fuels, some countries have invested in
alternative
energy
sources.
Although
there are some dangers in
this
new approach, I believe that the benefits outweigh the drawbacks. On the one hand, there are certainly some negative consequences of increasing reliance on
alternative
energy
sources. Perhaps the main concern is the issue of safety. Nuclear
power
is criticized for its potential to pollute the environment, and incidents
such
as the disaster at Fukushima Daiichi in Japan remind the public of the dangers of nuclear plants. The poisonous and radioactive emissions produced by the explosion not only killed many people, but
also
left a legacy of cancer deaths in the future. Another
energy
source, wind
power
, is criticized for a different reason.
For example
, many local communities oppose the installation of wind farms because they may affect the landscape and create too much noise from their generators.
On the other hand
, the key factor is that
alternative
energy
sources do not cause as much pollution as the burning of fossil fuels,
such
as oil or coal.
Firstly
, green
power
sources are eco-friendly and do not contribute to air pollution. As there are no carbon emissions, the problems of climate change and poor air quality can be tackled by increasing use of
alternative
energy
.
Secondly
, wind and solar
power
are both renewable sources of
energy
.
Instead
of depending on fossil fuels, which are becoming exhausted, the use of renewable
energy
will guarantee a boundless supply of
energy
for the future generation. In conclusion, I consider that it is important for governments and the public to support the use of
alternative
energy
sources, despite the safety concerns and other impacts.

Include an introduction and conclusion

A conclusion is essential for IELTS writing task 2. It is more important than most people realise. You will be penalised for missing a conclusion in your IELTS essay.

The easiest paragraph to write in an essay is the conclusion paragraph. This is because the paragraph mostly contains information that has already been presented in the essay – it is just the repetition of some information written in the introduction paragraph and supporting paragraphs.

The conclusion paragraph only has 3 sentences:

  • Summary
  • Restatement of thesis
  • Prediction or recommendation

Example:

To summarize, a robotic teacher does not have the necessary disciple to properly give instructions to students and actually works to retard the ability of a student to comprehend new lessons. Therefore, it is clear that the idea of running a classroom completely by a machine cannot be supported. After thorough analysis on this subject, it is predicted that the adverse effects of the debate over technology-driven teaching will always be greater than the positive effects, and because of this, classroom teachers will never be substituted for technology.

Start your conclusion with a linking phrase. Here are some examples:

  • In conclusion
  • To conclude
  • To summarize
  • Finally
  • In a nutshell
  • In general
