Our most esteemed administrators
and teacher, my beloved friends, ladies and gentlemen, a pleasant morning to
you.
The growing demand of energy has
resulted in the increasing consumption of fossil fuels such as coal, oil, and
gas. According to what scientists have said, it’s only a matter of time for
fossil fuels to run out. Moreover increasing use of fossil fuels also causes
serious environmental problems. When the oil and coal are burn they produce
huge amounts of carbon dioxide and other harmful gases that have a negative
effects on the environment. That’s why it is important for us to find
alternative and renewable energy sources like solar energy, wind, tide, biomas
and energy from waste material. These are called non-conventional energy
sources.
Non-conventional sources of
energy comprise those energy sources that are natural, inexhaustible as well as
renewable.
Solar energy is the most advanced
form of energy out of all the renewable energy sources. It has no side effect
to the environment. India is the country that has applied this kind of energy
source and India is planning to produce 20000 MW of solar power by 2022.
Wind energy can be used for
pumping water for irrigating farms in the countryside, also it can be used for
generating electricity. It’s used the power of air flow to drive the wind
turbines and generate electricity. China is a world leader in wind power
generation, with the largest installed capacity on any nation and continued
rapid growth in new wind facilities.
Bio gas is produced by using farm
and waste material. The power is produced to used for cooking and lighting
houses.
Tidal energy is another unlimited
and inexhaustible source of energy. It’s used the tidal power to generate
electricity. Australia, USA, South Korea, UK, China are the countries that have
applied this kind of energy source.
What about Indonesia? Well as we
know, Indonesia in the largest maritime nation in the world and Indonesia is
also blessed with an abundance of sunlight, and wind that makes Indonesia has
high potential to use those energy to replace the use of fossil fuels.
That’s the end of my speech, I hope
this speech is useful, and I hope Indonesia can apply those energy sources to
replace the use of fossil fuels as soon as possible.
