2. What is Solar Energy? Solar energy is energy from the sun.
This type of energy radiates every day.
Two types of this energy are space heating and hot water heating.
Space heating heats up a building with a device called a space heater.
Hot water heating supplies a home with a certain number of gallons of water.
Space Heating
Hot Water Heater

3. Where is Solar Energy Located?
Shortest- 91,400,000 million miles
Greatest- 94,500,000 million miles
 Mean- 93 million miles
Light takes 8 min. and 20 sec. to reach earth
Solar Hot water heating depends on where you live and how much hot water your uses.
Good water heater lasts years longer than Conventional water heater.
Solar energy panels are usually placed on roofs or areas with direct sunlight.

4. Two Types of Solar Energy
PV Electricity
Thermal Electricity
“solar cells”
Power calculators, toys, telephones call boxes, converting light into electricity
Use sun’s heat to make electricity

5. Current Information Reliability Active solar home
Solar energy is collected
Sunlight inside glass
absorbs sunlight and changes
into heat
Traps heat inside
ex: locked car on sunny day
light passes through windows
Seat covers, walls, and floors
absorb energy
Glass windows let in light
Do not let heat out
Reliability
Active solar home
Mechanical equipment as an
extra source
Does not operate on solar
energy alone
Pipes, fans, pumps
Is used when solar energy
does not have enough supply
to heat homes
Passive solar homes
Whole house operates on solar
energy
Doesn’t use pipes, fans, pumps
Relies on oriented window
Houses face south-sun shines

6. Advantages and Disadvantages
Oil
Environmentally friendly
Saves earths recourses
Fossil fuels
Wood
Collectors-pollution free
Can’t afford equipment to have homes run on solar energy
Works best when sun is shinning
Many times not shinning
Need back up equipment
Isn’t as convenient as using gas, oil, or electricity
Gas

7. I won’t die for another 5 billion years!
Future Prospects
The sun’s bright light
may last for another 5
billion years
Better for environment
Not a limited use
Does not use earth’s
materials
Many possible uses
1.) Storing solar heat by collecting
the energy in solar panels
2.) Photovoltaic electricity that detects and measures light intensity
3.) Solar thermal electricity that radiates the sun’s warmth and converts it into energy that we use
I won’t die for another 5 billion years!
