1 Pre-Visit Activity The SRP Powering Our Future Classroom Outreach Presentation

2 Energy

3 Energy – The Ability To Do Work

4 Classifications of Energy Going from potential energy… to kinetic energy! (stored energy; the energy of position) (energy of motion)

5 Energy Transformations Energy can change forms… Chemical energy becomes mechanical energy when… We pedal a bike!

6 Energy Transformations Electrical energy becomes thermal and radiant energy when… We turn on a light bulb!

7 Electricity

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

9

10 The Electromagnetic Effect

11 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?

12 Solar Energy

13 The Photovoltaic Effect

14 Who can name the two different types of energy sources? Energy Sources Renewable Non-Renewable

15 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!

16 Examples of Non-Renewables Coal Natural Gas

17 Examples of Non-Renewables Petroleum Uranium

18 Fossil Fuels Fossil fuels are non-renewable energy sources

19 Non-Renewable Benefits Inexpensive Infrastructure in place Abundant Efficient fuel source ✔ ✔✔✔ ✔✔✔✔ ✔✔✔✔

20 Non-Renewable Costs Pollution and mining damage the environment Contributes to climate change Limited supply ✔ ✔✔ ✔✔✔ ✔✔

21 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

22 Examples of Renewables Solar Wind

23 Examples of Renewables Hydropower Geothermal Power

24 Renewable Costs Won’t always work Might damage environment Can’t use everywhere Inefficient ✔ ✔ ✔ ✔✔✔ ✔✔ ✔

25 Renewable Benefits Clean - no pollution Don’t contribute to climate change Small, modularQuiet ✔ ✔✔✔ ✔ ✔✔✔ ✔✔✔ ✔✔
