Key Q: What other energy sources are there?

2. Energy from the Sun The sun has produced energy for billions of years
SOLAR ENERGY is the sun’s rays that reach the Earth
This energy can be converted into other forms of energy, such as heat and electricity

3. energy can't be created nor destroyed...only transformed
A basic law in physics is that…
energy can't be created nor destroyed...only transformed

4. In other words, take the sun's solar energy and transform it into the energy you need

5. -Drives photosynthesis -Drives the water cycle -Drives Wind
The Suns Energy…
-Provides heat
-Drives photosynthesis
-Drives the water cycle
-Drives Wind
-Can be converted into electricity using photovoltaic cells

6. Solar Heating Systems ACTIVE PASSIVE
Devices capture the sun’s energy
No equipment
Buildings with many windows allow heat in

7. sunlight directly into electricity
Solar energy can be converted to electricity in 2 ways:
PHOTOVOLTAIC CELLS
A device used to change
sunlight directly into electricity

8. CONCENTRATING SOLAR POWER PLANTS
generating electricity by using sunlight to heat a fluid which produces steam that is used to power the generator

9. How Solar Panels Work
AMS Solar Power

10. SOLAR Energy – ADVANTAGES
A RENEWABLE RESOURCE
DOES NOT EMIT POLLUTANTS
when generating electricity
Produces electricity very QUIETLY

11. CAN BE STORED FOR LATER USE
MORE ADVANTAGES…
Solar panels can be
installed on top of
many ROOFTOPS
(don’t have to find space)
Energy from the sun is FREE for years to come with virtually
NO MAINTENANCE
Solar Electricity
CAN BE STORED FOR LATER USE

12. FINANCIAL INCENTIVES SAVES YOU MONEY EVEN MORE ADVANTAGES…
from the government
SAVES YOU
MONEY
on your electric bill
(if you have one at all)
Allows us to become LESS DEPENDENT on fossil fuel supplies & foreign imports

13. EXCESS ELECTRICITY generated can be SOLD to power companies
A FEW MORE ADVANTAGES…
EXCESS ELECTRICITY generated can be SOLD to power companies
More solar panels CAN EASILY BE ADDED

14. SOLAR Energy – DISADVANTAGES
Solar Panels can be EXPENSIVE initially
Some households may need
MORE THAN ONE

15. LARGE AREA FOR INSTALLATION to achieve a good level of efficiency
MORE DISADVANTAGES…
Solar panels require a
LARGE AREA FOR INSTALLATION to achieve a good level of efficiency
Solar powered
CARS ARE
SLOWER

16. CANNOT BE GENERATED AT NIGHT
EVEN MORE DISADVANTAGES…
Efficiency relies on the
LOCATION OF THE SUN
Solar energy is
influenced by CLOUDS or POLLUTION
Solar power
CANNOT BE GENERATED AT NIGHT
