Classifications of Energy
Going from potential energy… to kinetic energy!
(stored energy; the energy of position) (energy of motion)
Energy Transformations
Energy can change forms…
Chemical energy becomesmechanical energy when… We pedal a bike!
Energy Transformations
Electrical energy becomesthermal and radiant
energy when…
We turn on a light bulb!
There is one energy source that can generate electricity WITHOUT using the electromagnetic
effect; it uses a different effect entirely… Can anyone guess what that energy source is?
Another Source?
Non-Renewable Energy Sources
• Formed in the Earth over hundreds of millions of years
• Must be extracted from the Earth, often involving mining or drilling
• By definition, they are limited. They will run out!

Renewable Energy Sources
• Come in many different forms
• Have been used by humans for thousands of years
• By definition, naturally replenish themselves…They will NEVER run out!
• Much cleaner than non-renewables
Renewable Costs
Won’t always work
Might damage environment
Can’t use everywhere
