renewable energy sources

1. RENEWABLE VS. NONRENEWABLE resources

2. This Week’s Assignments
No live classes Monday
ACH2 Secrets of the Sky
L4 Forms of Energy
CYU4 Brainpop Energy

3. Learning Goal
I can analyze ways in which our world uses
renewable and nonrenewable energy
resources and explain how energy is
stored and transformed

4. A major energy
transformation in
our lives is the
one that changes
various energy
sources into
electricity.

5. sources are those that can be replaced in
a relatively short period of time.
Example: solar energy, wind energy,
biomass and hydropower.
Renewable Energy

6. Solar Power
• wind energy is mostly the use
of wind turbines to generate
electricity.
• Light energy  electricity

7. Wind Power
Wind energy is mostly the use of
wind turbines to generate
electricity.
Wind moves the wind turbine
blades
Mechanical energy  electricity

8. GEOTHERMAL
Geothermal energy is the thermal
energy in the Earth's crust

9. Geothermal
• Thermal energy  electricity

10. HydroELECTRIC
generation of electricity using flowing
water (typically from a reservoir held
behind a dam or other barrier)

11. Hydroelectric
• Mechanical energy  electricity

12. BioMASS
• Chemical energy  electricity

13. sources cannot be replaced as they are used.
Example: nuclear energy, fossil fuels
Nonrenewable Energy

14. Fossil Fuels (oil, Coal, Natural Gas)

15. Nuclear
• Nuclear energy is formed by nuclear
fission. It is EXTREMLY powerful!
• While nuclear energy does not emit any
greenhouse gases, it does make
radioactive waste.
• Nuclear material is incredibly dangerous.
If accidents happen there are serious
health and environmental repercussions.

16. Brainpop Assignment
• Watch the video
• Answer the questions
• How does a wind turbine
create energy?
• How does a solar panel
create energy?
