The Sources of Renewable Energy
Renewable power is a very important topic today. Using a renewable
source of electricity it will help you to save a lot of money and it will also
help make this Earth a better place to live in. Renewable energy is a
form of electricity that doesn’t use the non-renewable natural resources
of the Earth. Non-renewable sources of energy are resources such as
fossil fuels like oil, natural gas, coal, nuclear, wood, etc.
Alternative energy sources such as wind, solar, hydro, and
geothermal
are all examples of renewable power. You can use as much sunlight
as you want, but the sun will keep on shining and provide us with more
energy to use. If we use the wind or the water to make the turbines
rotate, we can always get more wind blowing or water flowing, and
they never get used up.
Sources like fossil fuels and other non-renewable sources often cause
heavy pollution, causing trouble for the Earth, making it dirty and
polluted. The ecology gets affected when a resource gets used up. It
is also important to preserve energy by switching off
appliances
and
lights when not being used.
