Fossil fuel is the main source of energy. In some countries, the use of alternative sources of energy is encouraged. To what extent do you think is it a positive or negative development?

Throughout the world,

fossils

are the most used source of

energy

. They are used to power factories, run cars, fly planes, and so on.

However

, some countries are now encouraging the use of renewable

sources

. I believe

this

is a positive development because it will not only save our resources and reduce pollution but

also

help economies to thrive.

Firstly

, unlike fossil fuels, alternative

sources

are

carbon free

, which means there is no pollution when we use these

sources

to generate power. Burning petroleum products,

on the other hand

, emits a great deal of carbon dioxide – the biggest source of air pollution –

thus

devastating the environment and making it difficult to breathe fresh air.

Secondly

,

fossils

take millions of years to regenerate and are required in large quantities to produce little

energy

.

For example

, to

required, and at

this

unsustainably high rate, we will soon run out of these resources.

However

,

sources

like sunlight and water are unlimited, so we must invest in renewable

energy

and preserve

future generations.

Finally

, many countries are dependent on others for

fossils

because they have no

such

resources.

For example

, Pakistan spends billions of dollars each year to purchase natural gas from other countries.

This

has an adverse impact on the citizens, who have to pay higher taxes, which has many economic implications.

Therefore

, in order to save money and grow our economies, we need to switch to alternative

sources

, which are everywhere. In conclusion, the use of renewable

energy

has many positive aspects. If we give up on

fossils

and start using solar, wind, and tidal

energy

,

for example

, we can save billions of dollars

along with

preserving our natural environment and making life easier for our upcoming generations.
