Nick Vedovi: Renewable energy is the best solution to stop
global warming and keep the world green. Using renewable energy can save
hundreds, even thousands of dollars off your electric bill. Through renewable
resources, it is possible to become completely independent of electric
companies.
About 7% of the United States is powered by renewable
resources. The five most common methods to gather electricity from nature are:
Solar Power, Water Power (Hydropower), Geothermal Power, Wind Power, And Energy
From Biomass. Let's take a look further into each of these.
Solar power is energy gathered directly through the sun.
Solar panels are devices that can transfer the light rays into electricity. If
humans were 100% efficient and could gather all the energy from the sun that
hits the earth, we would only need to gather the energy for about a minute each
day. That's right, one minute's worth of solar energy could power the entire
world for a day. Nick Vedovi suggests that for our home, you can use solar
panels to supply your house with electricity.
How to Use Renewable Resources at Home |
Water power is the energy from moving water. Dams are a
great way to generate energy from water, the running water powers them.
Running water constantly flows out to the ocean, where it evaporates and
returns to land. This makes it renewable because the water cycle will always
continue to supply our streams and rivers with water. If you have a source of
water near your house, you can use a water mill to generate electricity.
Geothermal power is energy from within the Earth. Earth's
core is very hot, and consistently melt rocks and heats the water. You can dig deep
wells and pump the hot water or steam out of it, then you can use this heat to
heat your home.
Wind power is energy from the airflow that surrounds the
Earth. Wind turbines, similar to propellers on an airplane, can transfer this
pushing force into a spinning movement. This spinning movement can be used to
power a generator and supply you with electricity. The wind is caused by the uneven
heating of the Earth, basically, because warm air rises and cold air falls. The
states with the highest wind power are generally the border states because the
ocean produces high winds.
