3. What are the different types of
renewable energy?
Different sources…
4. Renewable Energy
Renewable energy is sometimes called
“clean energy” because it is considered to be
better for the environment than other types
of energy sources. Also called “alternative
energy.”
It is renewable because the source is
replenished constantly.
5. 5 Types of Renewable
Energy Sources:
• Biomass
• Geothermal
• Water (Hydropower)
• Wind
• Solar
6. Solar Energy
The sun provides most of the energy we use.
Solar energy is energy from the sun.
Solar panels collect energy from the sun and
convert it into energy we can use.
The energy from the sun can be
converted into heat and electricity.
Sunlight can be captured using
photovoltaic cells which convert the
sun’s energy into electricity.
7. Wind Energy
Energy is collected from the wind through
turbines – they make wind power.
Wind turbines can be found near the
ocean, in the ocean, and on tall hills where
it is windy.
As the wind blows it spins the large
blades on a wind turbine and generates
electricity.
8. Water Power
Also called hydro power.
We receive a lot of power from ocean
tides and from water dams.
The energy contained in running
water can be turned into electricity.
Water, which is impounded or held
behind a dam, is released through a
turbine that spins a generator
producing electricity.
9. Geothermal Energy
Traps heat deep down inside the Earth
– from the crust and core.
Uses heat generated by the earth’s
interior. By drilling down into the
Earth’s crust, much like we drill for
oil, we can use that heat to generate
electricity. Geothermal is a good
source for heating homes and
buildings.
10. Biomass Energy
Made up of biological material from living or recently
dead things (organisms).
Can be made up of wood, waste, plant matter,
garbage, and landfill materials.
Biomass: Is energy derived from plants and
animals. Biomass comes in many forms, the most
common being wood. When we use plants as a
source of energy we are converting their stored
energy from the sun. Using the methane gas given
off by landfills and animal waste is also becoming
more common. Another increasingly popular form of
biomass is in the form of biofuels such as ethanol
and biodiesel, which is also derived from plants and
animals.
