Transcript Renewable and Non – Renewable Resources

What is a Renewable
Resource?
In my opinion a renewable resource is
something that we can reuse and it will
constantly be replaced in nature. It could be
something we grow to eat or wear, or like trees
we constantly cut down to use.
What is a Non –
Renewable Resource?
In my opinion a non–renewable resource is
something that we use that we can not
reproduce, but instead find in the Earth. These
are usually used more, and at a faster pace, so
the Earth can not keep up and keep producing it
in time.
Hydroelectric Power
Hydroelectric power is electricity that is
generated using falling water to turn turbines.
Using Hydroelectric power to generate
electricity does not add to pollution because it
does not burn anything in the process. But it
does cause flooding to areas near the dam used
to generate the electricity, because it raises
water levels. It also can several ecosystems and
habitats. It is a type of renewable resouce.
Hydroelectricity Power
When generating hydroelectricity power we use dams to hold the
water on one side and let it fall down only when it runs through the
generator.
Wind Power
Wind power is another type of renewable
electricity. To generate this type of electricity
they have turbines turning using the power of
wind. Using wind power does not contribute to
pollution. It does have a drawback, because it
only a few places in the world has enough wind
to keep these wind turbines constantly moving.
Wind Power
When generating power with wind turbines it needs a constant
supply of wind. Only a few places in the world suit the conditions to
have a lot of electricity generated with wind turbines.
Solar Power
Solar Power is a renewable resource which
uses solar panels to generate electricity. They
put these solar panels in sunny places to absorb
sunlight. The drawback of these solar panels is
that they require a lot of sunlight, and if it
suddenly starts getting darker and the sun is
hidden by a cloud, then the solar panels no
longer can generate electricity.
Solar Panels
Solar Panels are used to generate energy using the power of the
sun. It creates no pollution and is a renewable resource that will be
here for a long time until it goes out.
Geothermal Energy
Geothermal Energy is another type of
renewable energy. This type of energy takes
heat from the Earth and changes it into a type of
energy we can use. Geothermal plants can last
up to 100 years, or even longer. The drawbacks
of these plants are that they can not be built in
most places, since the area needs to have a thin
crust in order to drill through the Earth. It also
costs a lot of money to drill to the Earth.
Geothermal Power Plants
Geothermal Plants use the heats energy to generate electricity.
Though there is no add to pollution, it could disturb the ecosystems
of wildlife. It also costs a lot of money to drill these plants.
Biomass Energy
Biomass energy uses living things like wood
or waste to generate electricity. Though this is
renewable it can destroy entire forests just to get
the wood. Several ecosystems are vaporized
because we cut down the trees to burn and
generate energy.
Biomass Energy
They burn wood as an example to generate heat. They are
renewable but it also takes a long time to grow the trees back that
they cut down.
