In some countries, the use of renewable energy sources is being encouraged. Is it a positive or negative development? Give reasons for your answer and include any relevant examples from your own knowledge or experience.

It is a fact that nowadays, some
countries
prefer using green
energy
sources
such
as
wind
power
or solar
power
. In my opinion, it may be difficult for a country to move toward using renewable
energy
sources
, but it will bring some irrefutable advantages and become a positive development. On the one hand, the changes in terms of using green types of
energy
sources
would probably put a heavy financial burden on the government as well as the company. They may have to purchase a million dollars to upgrade new equipment and facilities harnessing
wind
, solar
power
, or 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. Resulting in many
countries
, especially developing
countries
or poor economic
countries
such
as Africa, can not afford to use these
power
sources
.
On the other hand
, the advantages outweigh the drawbacks in terms of the long run.
Firstly
, fossil
fuels
are the main cause of environmental pollution, since petroleum-powered vehicles and factories are releasing tremendous amounts of CO2 into the atmosphere every day.
Therefore
,
instead
of using coal and petroleum that emit a lot of carbon dioxide into the atmosphere, using
wind
power
or solar
power
will help to reduce the emission 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
run out. In conclusion, I believed that
countries
should be encouraged to replace fossil
fuels
with renewable
energy
sources
because of the environmental purposes and long-term purposes.
