Energy

Energy – The Ability To Do Work

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!

Electricity

How do we begin with an energy source and end up with electricity?

Energy Transformations

Energy Transformations

The Electromagnetic Effect

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?

Solar Energy

The Photovoltaic Effect

Who can name the two different types of energy sources?

Energy Sources

Renewable

Non-Renewable

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!

Examples of Non-Renewables

Coal Natural Gas

Petroleum Uranium

Fossil Fuels

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

Examples of Renewables

Solar Wind

Examples of Renewables

Renewable Costs

Won’t always work

Might damage environment

Can’t use everywhere
