RENEWABLE RESOURCES
Resources that can be used over and
over again to produce energy without
fear of running out. These resources
replenish themselves naturally.
Solar Energy
•
•
•
•
•
Heat energy**
Light energy**
Used to tell time
Can be used for cooking
Can be used to help purify water
Wind Power
• The use of wind energy dates back
thousands of years.
• It was originally used to pump water for
wind mills.
• Generates electricity
Hydroelectric Energy
• Electric energy produced by the action
of falling water
• Electricity generated by water flowing
downhill
Biomass Energy
• Energy from the sun is necessary for
biomass energy
• Biomass energy contains energy stored from
the sun - plants and photosynthesis
• Biomass = natural materials
• Form of electricity produced from
plant/animal waste
• Energy that can be used through the use of
burning (sawdust, tree bark, trees, grasses)
Biomass Energy
• Biomass can pollute the air when it’s
burned, but not as much as fossil fuels
• Biomass releases carbon dioxide,
which is also known as a Greenhouse
Gas (greenhouse gases are bad for the
environment because they trap heat
from the sun in the Earth’s atmosphere)
Biomass Energy
• Burning Wood
• Using corn as fuel
• Biodiesel is a form of fuel made with
vegetable oils, fats, grease (recycled
from restaurants sometimes)
Geothermal Energy
• Energy generated by converting hot
water or steam from deep beneath the
Earth’s surface into electricity
• Heat transferred from the Earth’s core
• Natural heat can be used to generate
electricity and heat homes and
businesses
Wave/Tidal Energy
• Energy powered from the surface of
waves
• Rise and fall of waves causes rotation
of object so energy can be made
NON-RENEWABLE
RESOURCES
• A natural resource that cannot be remade, re-grown, or regenerated
• Exists in a fixed amount that is used up
faster than it can be made by nature
Non-Renewable
Resources
• Non-renewable resources are also
called fossil-fuels. The natural
resources (coal, oil, natural gas, and
nuclear energy) are named this
because of fuels found in the top layer
of the earth’s crust
Coal
• Formed in swamps where plant
remains were saved by water and mud
• Coal is a burnable black rock
• It is the largest single source of fuel for
electricity world-wide
• Coal is dug up from the ground by
surface mining or deep mining
Crude Oil or Petroleum
• Naturally occurring liquid found within
the earth
• Burned oil generates heat, electricity,
and sometimes lighting.
• Used for powering engines
Natural Gas
• Cleanest and safest of energy sources
• Odorless, colorless gas that smells
sometimes like rotten eggs
• Sources of natural gas are swamps,
marshes, and landfills
• Delivered to homes through pipelines
• Natrual gas is used for heating, cooking, and
bunsen burners
Nuclear Energy
• Nuclear energy relies on the splitting of
the element Uranium atoms in a
process called fission. This generates
heat for producing steam that then
makes a turbine produce electricity
