There are two types of
energy. Nonrenewable and Renewable. ( I think renewable energy is what my 5yr
old is made of.)
Energy sources are considered nonrenewable if they
cannot be replenished (made again) in a short period of time. Some examples of
nonrenewable energy include gasoline, diesel fuel, propane, coal, natural gas,
and uranium (nuclear energy).
Renewable energy is energy generated from natural-occurring
sources that can be constantly replenished in a short period of time. The five
renewable sources used most often are Biomass, Water, Geothermal, Wind and
Solar.
The use of renewable
energy is not new. The
oldest and perhaps most common energy is wood. More than 150 years ago, wood,
which is one form of biomass, supplied up to 90% of our energy needs. As the
use of coal, petroleum, and natural gas expanded, the United States became less
reliant on wood as an energy source. Over half of renewable
energy goes to producing
electricity. About 9% of U.S. electricity was generated from renewable sources
in 2008. The next largest use of renewable energy is the production of heat and steam for
industrial purposes. Plants have more recently been used to create renewable
fuels, such as ethanol (alternative to gasoline) are also used for
transportation and to provide heat for homes and businesses. Geothermal energy
is another type of renewable energy that involves harnessing the natural heat of
the earth's core to produce power.
The largest source of renewable
energy currently used is
hydroelectric power. Hydroelectric power involves harnessing the kinetic
energy of flowing water to turn turbines in order to produce electricity. A
similar form of renewable energy is wind power, which involves harnessing the
kinetic energy of wind currents to turn large fan-like turbines. Solar power, involves using the light and heat produced by the
sun as an energy source. The power from the sun is so efficient, and it can be
used for everything. Simple examples are things like lighting the pathway in
the garden, security lights, or heating the pool. There are so many small
devices that run on solar energy, that this alone can save you a lot of money.
Together with residential solar panels you can switch from regular electricity
to solar renewable energy.
For the future of the
earth you need to understand that one of the most important benefits is the
environment. The amount of electricity we use is the cause of extreme issues
like global warming and pollution of the environment. When we start using the
sun to its fullest capacity we are using a completely natural and
environmentally friendly energy source.
Given the increasing
population of the human race, the importance of renewable
energy is likely to
continue to increase in the future, as well as a shift toward more cost
efficient energy sources. From the standpoint of electrical
power, solar energy has a huge potential, considering the amount of
energy the sun produces is thousands of times greater than the needs of earth.
The world must transform its current energy system on a global scale. It is
expected that 60% of all our energy will come from renewable energy by the year
2070.
