Fossil fuels are the main source of energy around the world. However, people are being encouraged to use alternative energy sources such as wind energy, solar energy and so on. Do you think this is a positive or negative development? Why?

It is clear that fossil fuels are being used as a major repository of
energy
all over the world. While. There is some effort to motivate people to use other types of
energy
such
as wind
energy
, solar
energy
, and so on. I would argue that it is definitely a positive development. People need to be encouraged to replace fossil
fuel
with green types of
energy
. The major problem of using fossil
fuel
is air pollution. While fossil
fuel
burned, the CO2 and other kinds of toxic gasses would be released into the air. These harmful gasses cause the
weather
binary compound that occurs at room temperature as a clear colorless odorless tasteless liquid; freezes into ice below 0 degrees centigrade and boils above 100 degrees centigrade; widely used as a solvent
water
to be polluted, and it has several side effects on the environment and people’s health.
For example
, respiratory disease is one of the diseases that appear in humans and other animals, because of air pollution.
In addition
, fossil
fuel
causes a phenomenon called Global Warming.
This
phenomenon is one of the main concerns
in
Suggestion
of
the whole world because many species would be
extincted
no longer in existence; lost or especially having died out leaving no living representatives
extinct
if people did no action. In my opinion, using green fuels has several advantages.
Firstly
, the Earths’ environment needs to be clean and safe for all species, so, it is worthy to use clean sources of
energy
.
Secondly
, by using alternative fuels, the weather condition goes
to
Suggestion
into
a good situation.
Finally
, the green sources of
energy
are mostly renewable, so the
energy
concern will be solved, if people use green fuels.
For instance
, in Island, they provide 85% of their
energy
from renewable sources,
such
as wind
energy
. In conclusion, in my opinion, it is a great effort to invite people to consider other types of
energy
.

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
