The world is heavily dependent on oil for energy, which is unsustainable due to global warming. What future resource do you think will take oil’s place? Why do you think this?

Most would agree oil has been a main
energy
source all over the world, but it is undeniable that it has devastating effects on the environment as well as human health. With a major breakthrough in humanity’s ability to harvest
power
from the sun, it is argued that solar
power
will one day become an eco-friendly and affordable alternative to fossil fuels.
This
will be shown by analysing reasonable
cost
of solar
energy
per watt and its positive effect on the environment.

For example
, an article of IRENIA on Forbes newspaper in 2017 reported that the price of electricity generation based on fossil fuel was 0.3$/ kWh, in comparison with 0.17$/kWh of solar
energy
.
In addition
to
this
, it was predicted that the solar
cost
would fall even
further
in the
next
few years. What
this
mean is that, it would be more economical to use cars running with solar
energy
instead
of petroleum. As people are driven by price, it is clear that solar
power
will take the place of oil-based

Secondly
, solar
energy
is known to be environment-friendly, which comes
as a result
of its harnessing from the sun.
For instance
, in order to produce
energy
from fossil fuels, industries have been producing a great amount of carbon dioxide that has not only impacted on airborne pollution but
also
on health issues.
Conversely
, as in the case of solar
power
, it generates
energy
from sunlight, which is an infinite resource and reduces subsequent global warming to no carbon dioxide emission throughout producing process.
This
advantage of green
energy
is another reason that solar
power
is suitably an alternative to petrol. In summary, after looking at both advantages of reasonable price and positive effects on the environment, it can be seen that solar
energy
will take the role of the main source over oil. For the sake of the world’s health, it is hoped that
this
transfer will happen sooner rather than later. 11. The world is heavily dependent on oil for

Support ideas with relevant, specific examples

Examples make your writing easier to understand by illustrating points more effectively.

Examples, if used properly, not only help you get higher marks for ‘Task Response’ but also for ‘Coherence’.

When giving examples it is best to put them after your main idea or topic sentence. They can be used in the middle of supporting sentences or they can be used to start a new sentence. There is no rule for where exactly to give examples in essays, logically they would come after your main idea/topic sentence or just after a supporting sentence.

Linking words for giving examples:

  • for example
  • for instance
  • to illustrate this
  • to give a clear example
  • such as
  • namely
  • to illustrate
  • take, for example
