Some people think it for granted that
alternative energy seems more expensive than fossil fuels. Thus, it is better
for us to use those energy. However, in my opinion we should use alternative
energy sources such as solar and wind. This is because they are helpful to
overcome energy crisis and good to people’ health.
Admittedly,
alternative energy sources might have problems. When we make solar panels to
get energy from the Sun, it generates harmful materials such as CO2 which is a
main reason for global warming, grease which is used between parts on the
panels, and non-disposable wastes which are plastics. Additionally, building
the solar panel requires large areas of tract to install. Also, there is
another type of renewable energy, wind power. It destroys natural landscape and
promotes wind erosion leading to detrimental situation for the environment.
However,
renewable energy sources is helpful to overcome energy crisis. Fossil fuels
ranging from coal to natural gas have been almost depleted. Thus, we need to
take action to use alternative energy, reducing the use of fossil energy. As an
example to explain, I set up a water boiling machine using sun power in my
house. This is because I cannot stand up any more skyrocketing electricity
fees. An electricity company in Korean said they had no choice but to raise the
price for generating electricity due to the small amount of oil, coal, and
natural gas in the world recently. However, thanks to the water boiling device
without using electricity, I can save a lot of money for monthly utility fees.
Moreover,
green energy sources do good to our health. This is because such a kind of
energy does not create toxic chemical materials for living things on the Earth.
To be more specific, coal and petroleum generate exhaust fumes when burned.
These pollutants will easily be changed to acid rain, having negative impact on
earth and water. Thus, any creatures including human beings would be highly
damaged to health. For example, according to one of medical reports in Korean
national hospital, nowadays, hundreds of thousands people living in heavy
developed industry society are suffering from physical diseases such as
headache, high blood pressure, and asthma. These kinds of ailments result from
air pollutions by millions of cars and lots of factories. Also introducing air
pollutions into earth turns out to be a main reason for the deformation of
flora and fauna. Had it not been for using of fossil fuels, the people would be
healthy today. Thus, we should rely on alternative energy source for both
people and animals living on the Earth.
All
things considered, although it is better for make use of fossil fuels because
of cheaper prices, I strongly believe that we have to use more green energy
sources instead of fossil ones. The reason is that using alternative energy not
only provide a valuable chance to overcome energy crisis, but also make people
stay in shape. |
