1 Do-Now 1.) Get out notebook. 2.) Answer the following questions on the first clean sheet in your notebook. 1.) What are renewable resources? 2.) What are nonrenewable resources?

2 Alternative Sources of Energy

3 Nonrenewable vs. Renewable

4 Non-renewable What is non-renewable energy? Energy sources that can not be replenished in a short period of time

5 Renewable Energy What is renewable energy? Energy that can be replenished naturally

6 Musical Energy The game starts in There is enough oil for everyone in the class to share. When the music stops, we will be in the year 2015, and there will be less oil. Students who don t have an oil rig will have to sit down. We will continue to stop the music every 5 years.

7 Musical Energy How realistic is conflict in a world of resources that are going to run out? How important is renewable fuel for the future?

8 Energy Efficiency and Energy Conservation Energy conservation is any behavior that results in the use of less energy. Turning the lights off when you leave the room and recycling aluminum cans are both ways of conserving energy.

9 Energy Efficiency and Energy Conservation Energy efficiency is the use of technology that requires less energy to perform the same function. In regards to the musical chair activity, how important is energy efficiency?

10 Examples of Renewable Sources Geothermal- uses the heat that comes from deep rocks under the surface of the Earth. Hydroelectric- generated from running water. (United Streaming Video)

11 Examples of Renewable Sources Solar- The sun releases energy due to the nuclear fusion of hydrogen taking place within its core. The solar panels convert the sun s energy into electricity. (United Streaming Video)

12 Examples of Renewable Sources of Energy Wind- used to turn wind turbines and make electricity (United Streaming Video) Biomass- uses the energy from plants and waste materials to make electricity. For example, wood can be burnt to make steam that turns turbines to make electricity

13 Examples of Non-renewable energy Oil and gas- fossil fuels that were formed millions of years ago. Organisms died and the carbon in their bodies was eventually turned into oil and gas. Coal-a fossil fuel that was formed millions of years ago when trees and plants died and formed a layer of peat. These layers continued to develop layers, which turned the peat into coal.

14 Pros of Solar Energy It is renewable Gives off no pollution Can be installed on rooftops Eventually, it will be cost-effective to the user Allows us to become less dependent on fossil fuels

15 Cons for Solar Energy The cells are expensive Weather can impact the efficiency of solar cells Pollution can impact the efficiency of solar cells

16 Pros for Wind Energy It is renewable Wind is free Wind turbines do not produce pollutants or greenhouse gases Eventually, it can be cost effective

17 Cons for Wind Energy Turbines can be damaged during storms Can be harmful to wildlife Noise can be disturbing Low wind speed can impact efficiency

18 Pros for Biomass It is renewable Plethora of waste Biomass briquettes is much cleaner than the electricity produced by fossil fuels It is cost effective

19 Cons for Biomass Some of the gases emitted during the biomass production may contribute to global warming The extraction of biomass can be expensive Biomass power plant requires a large space

20 Pros for Hydroelectricity No waste or pollution Can be used throughout the world Energy is virutally free More reliable than wind, solar, or wave power Water can be stored above the dam ready to cope with peaks in demand Hydroelectric power stations can increase to full power very quickly, unlike other power stations The sun provides the water by evaporation from the sea Could eliminate the cost of fuel

21 Cons for Hydroelectricity Smaller models depend on availability of fast flowing streams or rivers Run-of-the-River plants can impact the mobility of fish and other river life Dams are very expensive to build Building a large dam will flood a very large area upstream, causing problems for animals that used to live there Finding a suitable site can be difficult Water quality and quantity downstream can be affected, which can have an impact on plant life

22 Exit Slip Question Which type of alternative energy do you think is the best to use? Why do you choose this type?
