Why do we need alternative sources of energy?
Limited Supply of Fossil Fuels
How fossil fuels are formed
Uses of Fossil fuels
Rate of usage
How Fast
It Is Renewed
When fossil fuels will be used up
Causes
Effects
burning fossil fuels
devastates coastal cities and island nations
Pros
Cons
Carbon neutral
Smells bad
Pros
Cons
Abundant sunlight
Easily renewed
Don't release any carbon dioxide
Don't produce much electricity
Expensive
Sunlight can be blocked by clouds
No sun at night
Over millions of years, heat and pressure turns organic material into fossil fuels.
