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
