Many countries use fossil fuels such as coal or oil as the main sources of
energy. However, in some countries, the use of alternative sources of energy
is encouraged. Do you think this is a positive or negative development?
There was a heated controversy over that whether countries should encourage the
use of new energy sources replacing fossil fuels namely coal or oil. I completely
agree with this idea.
There are some reasons why people have to seek other sources of energy. Firstly,
thanks to the application of alternative energy sources, many countries will avoid
the running out of natural materials. Coal and oil are limited whereas wind or
wave energy is renewable/ unlimited energy that might guarantee a boundless
supply of energy for the continuously increasing population. In addition, some
countries that don't have natural fossil materials could decline the dependence on
fuels from others. For example, there have been a lot of homeless residents in
European nations died in winter due to the lack of energy for heating while
Russian government imposed the energy sanction to close oil pipeline from Russia
to Europe.
Apart from the practical benefits expressed above, the key factor is that
alternative energy resources might solve environmental issues mainly deriving
from fossil fuels. It is obvious that burning coal or oil releases a large amount of
carbon dioxide which traps heat from the sun in the atmosphere. This process has
been causing the global warming, as a direct result of an increase of weather
extremes and sea level rise which are posing an imminent threat to the very
security of humans. Hence, green power sources also help to cut down the amount
of carbon dioxide emission and make climate change to occur more slowly.
Moreover, these kinds of energy are eco-friendly that do not contribute to air
pollution that affects directly on people's health.
In conclusion, I have strong belief that innovations to create green power sources
should be given top priority thanks to a safe and sustainable habitat for humankind.
