The exploration and development of safe alternatives to fossil fuels should be the most important global priority today. To what extent do you agree or disagree? Give reasons for your answer and include any relevant examples from your own knowledge or experience.

Since the beginning of the industrial revolution in previous centuries and the globalization of the world in the

last

two decades, the consumption of fossil materials has increased dramatically.

Thus

, people have begun to believe that it is highly essential to find other

sources

of

energy

.

This

essay totally agrees with

this

opinion and will

first

discuss why it is worthwhile to consume different

energy

sources

to preserve the environment and

then

will consider a problem related to the shortage of nonrenewable

energy

.

To begin

with, it has to be emphasised that the burning of fossil

fuels

, namely oil, natural gas and coal produces greenhouse gases that affect the environment by heating up the atmosphere and depleting the ozone layer.

As a result

, it causes global warming and climate change.

Therefore

, by using renewable power

such

as solar, wind, nuclear

sources

and hydropower people could avoid or at least reduce a negative impact on the habitat.

For example

, the

last

report of the Department of Humanity Issues of Germany presented the data confirming that the percentage of greenhouse gases decreased by seven per cent in the previous two years through the usage of solar

energy

.

Moreover

, it is no denying the conviction that fossil

fuels

seem to be a resource of insufficient amount. Speaking

in other words

, these types of

fuels

might run out by the end of the century.

This

means that the community should utilize not only unrenewable

energy

but cleaner one as well.

For instance

, the Russian

energy

company Gazprom declared that the quantity of natural gas is rapidly declining since the beginning of the twentieth century because it is one of the most consumed

sources

of

energy

. In conclusion, decreasing the usage of unrenewable

energy

and replacing it with other

sources

is a dominant purpose of today's society.

This

aim has to be achieved due to the harmful impact of fossil

fuels

on the environment and the possible extinction of these mentioned

energy

sources

.
