1. Comparing Methods of generating electricity

2. Energy sources can be grouped into two broad categories
Energy sources can be grouped into two broad categories. Non-renewable energy sources and renewable sources.
Renewable resources are sources that can be replenished by natural processes in a relatively short time
Non-renewable energy are sources that are limited and cannot be replenished naturally

3. Pro’s and Cons Can generate energy quickly Fairly inexpensive
Non-renewable
Renewable
Can generate energy quickly
Fairly inexpensive
Produces large amounts energy with little fuel
Releases pollutants into the atmosphere
Hazardous to humans in some cases
Uses natural energy
Don’t have to worry about the resource running out
Doesn’t create green house gases and pollution
Unpredictable sources
Sometimes expensive to generate energy through sources
Sometimes could cause changes to animal lifestyles

4. Electrical Energy Production In Canada
Worlds largest producer of hydroelectricity, Ex; Niagara Falls
Large part of energy comes from non-renewable resources, Ex; Coal, Uranium etc.
P.E.I was dependent on outside electricity because of limited sources
Electricity generated in Canada in 2007

5. Energy generated worldwide in 2007
A Sustainable Choice
Sustainability means using resources at a rate that can be maintained indefinitely
Since 66.6% of our energy is fossil fuels and non-renewable resources, we may never be able to achieve full sustainability.
Smaller actions such as turning off the lights when you leave the room can save the amount of energy you used.

6. Relating to the Real World
Most houses now use solar panels to heat water.
Hydrogen best choice of fuel in future because it can be burned like other fuels or converted into electricity.
Save water by taking shorter showers and low flow toilets.
Energy is a big part of our lives and we use it for most tasks.
