Energy has a various examples of renewable
and nonrenewable resources, and the common used example of examples of
renewable and nonrenewable resources is electricity.
Most of our electricity comes from power stations that use fossil
fuels like coal, oil and gas to generate the electricity. They are called
nonrenewable resources because you can't make any more and they will eventually
run out. Unfortunately, burning fossil fuels produces greenhouse gases
like carbon dioxide and methane which may cause global warming.
Renewable resources like the sun, wind, waves and the heat of the
earth are also examples of renewable and nonrenewable resources which are used
to make electricity. Renewable resources
can be used again and again and should not run out. Renewable resources are either
carbon neutral or do not produce greenhouse
gases so are much less harmful to the environment
Biomass is another example of examples of renewable and nonrenewable resources which uses the
energy from plants and waste materials
to make electricity. For example, wood or animal droppings can be
burnt to make steam that turns turns
turbines to make electricity.
Nuclear fuel is another example
of examples of renewable
and nonrenewable resources which is made from radioactive Uranium
Ore which occurs naturally in the ground,
particularly in Australia, Canada
and America.
It is also known as yellow
cake for its distinctive bright yellow color. The yellow Uranium Ore
is purified to provide the shiny
Uranium metal used in nuclear power plants.
Waves are another example of examples of renewable and nonrenewable resources which are created by the wind blowing across the sea and by the gravitational force of the moon. Wave power uses the energy of the waves to turn turbines that make electricity.
Coal
is a fossil fuel and is another
example of examples of
renewable and nonrenewable resources
which was formed in the Carboniferous period millions of years ago, (before the
dinosaurs!), when the earth was covered with oceans, swamps, trees and plants!
When the trees and plants died they formed a layer of peat, which over time
became buried by more and more layers of clay, sand and rock. Over millions of
years, the pressure of these extra layers turned the peat into the coal we put
on our fires and fuel our power stations with today
Oil
and gas are fossil fuels and are another
example of examples of
renewable and nonrenewable resources
which were formed in the Carboniferous period millions of years ago when tiny
sea creatures called diatoms died and sank to the bottom of the oceans. As more
and more layers of sediment covered the sea creatures, they were crushed by the
massive pressures and the carbon in their bodies eventually turned to oil and
gas.
We
burn this oil and gas in power stations today.
Wind
is another example of examples of renewable and nonrenewable resources which is
made when the Sun heats the Earth and the area above land gets hotter than the
area above water. The hot air above land rises upwards leaving an area of low
pressure. Cooler air moves into this area of low pressure making wind which we
use to turn wind turbines and make electricity.
Wind used to be used to turn windmills to grind wheat into flour.
Tidal
energy is another example of examples of renewable and nonrenewable resources which
comes from the movement of water in the sea by the tides. These tides happen
twice a day. The flow of water that is created by the tides is used to turn
generators that make electricity.
