How do we use energy?

Why are we so inefficient?

Energy efficiency  How can we improve efficiency… In transportation? In transportation? In heating our homes? In heating our homes? In using electricity in our homes? In using electricity in our homes? In industry? In industry?  How can I be more efficient with energy in my life?  How can I make an impact on energy efficiency in my school? Town? County? State? Country? World?

Using energy resources  Why do we use certain energy sources?  What energy sources can/should we be using?  Remember: TRADE-OFFS!!!  For each energy source, consider: Availability – How much do we have? Where can we find it? How long will we be able to use it? Availability – How much do we have? Where can we find it? How long will we be able to use it? Acquisition – How do we extract, acquire, and/or process the energy for use? How efficient is our technology? Acquisition – How do we extract, acquire, and/or process the energy for use? How efficient is our technology? Economics – How cheap is it? How economically viable is it to use now? In the future? Economics – How cheap is it? How economically viable is it to use now? In the future? Impact – How does acquiring and using this resource impact human health? How does acquiring and using this resource impact the environment? Impact – How does acquiring and using this resource impact human health? How does acquiring and using this resource impact the environment?

Your task:  Alone or with a partner, use the textbook to fill in the information in the fact sheet for each energy source.
