Fossil fuels, such as coal, oil and natural gas, are the main source for many countries. However, some nations are using alternative energy such as solar power and wind power. Do you think this is a positive or negative development?

Although

fossil fuels still remain the most important

energy

sources in many places, some countries are now already using

alternative

sources like solar or

wind

power

. In my opinion, it can be difficult for a country to move towards using

alternative

energy

at

first

, but

this

development brings about several benefits in the long run. On the one hand, the change towards using

alternative

types of

energy

would probably put a heavy financial burden on the government and companies as they will have to invest millions of dollars in purchasing and developing new equipment and facilities for harnessing solar,

wind

or

hydro-electric

of or relating to or used in the production of electricity by waterpower

hydroelectric

power

.

For example

, the average cost of installing a

wind

turbine for generating electricity is about $3 million, and an average country would require a

wind

farm with hundreds of turbines to supply

power

to all companies and households.

In addition

, the production cost of large solar panels is still very high, which is why many countries, especially those with a poor economy, are still unable to use

this

power

source.

However

, I still believe that shifting towards using

alternative

energy

is a worthwhile investment due to the great benefits it brings.

Firstly

, fossil fuels are the main cause of air pollution nowadays since petroleum-powered vehicles and factories are releasing tremendous amounts of CO2 into the atmosphere every day.

Therefore

, replacing coal and petroleum with

wind

or solar

power

will help to reduce the level of emissions in the atmosphere and improve air quality.

Secondly

, 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 inevitably run out.
