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.Submitted by hoctotnha on
