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

production, it is suggested that

such

and solar

should rather be exploited.

Although

Linking Words

I deem that

this

Linking Words

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

energy

Use synonyms

.

Firstly

Linking Words

, prohibitive construction costs of plants that exploit

such

power

Use synonyms

would place a heavy burden on government funds.

For example

Linking Words

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

power

Use synonyms

on a large scale.

Secondly

Linking Words

, 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

, and they cannot use solar

power

to generate electricity at night, which proves

to be ineffective.

Nonetheless

Linking Words

,

due to

Linking Words

certain great benefits, I believe that promoting the use of

alternative

energy

Use synonyms

seems vital.

First,

Linking Words

in light of environmental contamination, renewable

energy

could be a good substitute for fossil

fuels

Use synonyms

. In comparison with fossil

fuels

Use synonyms

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

Linking Words

, fossil

fuels

Use synonyms

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

alternative

Use synonyms

sources

Use synonyms

.

This

fact emphasizes the need to develop renewable

energy

Use synonyms

to gradually replace traditional

sources

when fossil

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

alternative

energy

Use synonyms

, the switch from fossil

to renewable

is a positive and sustainable development for the planet.
