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.
