Fossil fuels (coal, oil and natural gas) are the main sources in many countries. However, in some countries, the use of alternative sources of energy (wind and solar energy) are encouraged. Do you think it is a positive or negative development?

In many parts of the world, despite fossil

fuels

energy

production, it is suggested that

alternative

sources

of

energy

,

such

as

wind

and solar

energy

should rather be exploited.

Although

I deem that

this

suggestion is not without negatives, its positives would be more significant. There could be two disadvantages of the change towards using renewable

energy

.

Firstly

, prohibitive construction costs of plants that exploit

such

power

would place a heavy burden on government funds.

For example

, it would cost the government millions of dollars to build a hydroelectric dam or install solar panels to harness solar

power

on a large scale.

Secondly

, it would be demanding to operate

wind

turbines or solar panels every hour. Specifically, some countries where

wind

is usually light are unable to rely on

wind

power

, and they cannot use solar

power

to generate electricity at night, which proves

such

sources

of

energy

to be ineffective.

Nonetheless

,

due to

certain great benefits, I believe that promoting the use of

alternative

energy

seems vital.

First,

in light of environmental contamination, renewable

energy

could be a good substitute for fossil

fuels

. In comparison with fossil

fuels

which emit tonnes of carbon dioxide emissions when they are burned,

wind

, solar and tidal

power

are entirely natural

sources

of

energy

which prove eco-friendly and release no harmful gases, reducing the levels of air pollutants and improving the air quality.

Furthermore

, fossil

fuels

, like natural gas or oil, are finite resources and will soon be depleted, which will potentially threaten the economy if there are no

alternative

sources

.

This

fact emphasizes the need to develop renewable

energy

to gradually replace traditional

sources

when fossil

fuels

run out. In conclusion, notwithstanding a number of drawbacks of harnessing

alternative

energy

, the switch from fossil

fuels

to renewable

energy

sources

is a positive and sustainable development for the planet.
