Define: Renewable Energy
Renewable Energy is a source of energy that can be restored more quickly than it is used.
What type of machine uses sun to create electricity?
Solar Panels
Where can Fossil Fuels be found?
Deep Underground
Do humans use energy? In what ways?
Yes we all use energy. Our bodies need energy to function and we also use electricity to power things like computers and lights. We also use energy from burning fossil fuels to power our cars, trucks, and buses.
Are energy sources unlimited?
Some energy sources are more limited than others.
Define: Nonrenewable Energy

What type of machine uses wind to create electricity?
Wind Turbines
What are the 3 types of Fossil Fuels?
Coal, Oil, Gas
Why are renewable energy sources important for the Earth's future?
If we are still relying on non-renewable energy sources when they run out, we will not have enough energy to meet our daily needs.
What are the three factors that affect resource availability?
Demand, location, and technology
Define: Fossil Fuels

Geothermal Energy
How are prehistoric plants and animals transformed into fossil fuels?
Pressure and heat
Why are humans trying to get away from nonrenewable resources?
-They take hundreds to millions of years to recreate.
-The cause pollution to the Earth.
Benefit: They do not produce air pollution
Impact: If not contained, can expose people to harmful radiation.
