Since more people start to concern for
energy sources, there is an ongoing debate over whether renewable sources of
energy will replace the fossil fuels. I agree with this statement because more
countries are trying to protect the environment than before and science
technologies will invent more products that make use of renewable sources of
energy.
To
begin with, the concern for the environment is gradually increasing in many
countries. It is evident that while renewable sources of energy such as solar
heat, wind power do not destroy environment, the use of fossil fuels
necessarily brings about environmental problems because it pollutes the air and
causes climate changes. If we burn fossil fuels, it emits toxic gases, such as
sulfur dioxide and greenhouse gases. Theses harmful byproduct can cause serious
illnesses such as respiratory problems and make the earth abnormally warmer. Consequently,
more countries are trying to cooperate in order to reduce the use of fossil
fuels and conserve the environment. For example, recent UN report reveals that
30 countries agrees with the reduction of burning fossil fuels at present and
up to 2020, 10 more countries are going to take part in such efforts. This implies
that more countries will replace fossil fuels to other sources of energy which
do not cause environmental problems. Therefore, it is highly likely that
renewable sources of energy will replace the fossil fuels.
In
addition, advancement in scientific technology will make it possible to change
fossil fuels to renewable sources of energy. This is because scientific
technologies have widely changed our lives beneficially at a fast rate. Accordingly,
scientists will develop the way to practically use renewable sources of energy.
For example, couple of years ago, many vehicle companies invented hybrid
vehicles that run on gas and electricity. Moreover, the Ford company, one of
the famous vehicle companies in the world, recently announced that solar cars
will be used in our usual lives within 5 years at a low cost. This implies that
the development of scientific technology will enable renewable sources of energy
to be used in our real lives.
In
conclusion, I strongly believed that fossil fuels will be surely substituted by
renewable sources of energy. This is because not only is increasing the concern
for environmental problems in the world, but also improvement in scientific
technology will allow for more uses of renewable sources of energy. All in all,
it is important to use resources effectively. However, we should bear in mind
that we should find the way to develop our world sustainably. |
