Tar Sand

1) Which energy source should we extract and use first, oil shale or tar sands? Why? 
      We should extract and use tar sands first because it doesn't require so much digging, and it could be less harmful to the environment it is in. It also only requires steam to extract. 

2) Describe one similarity between the process used to get oil from tar sands and the process used to get oil from oil shale.
      A similarity between getting oil from tar sands and from oil shale is digging. They both require some drilling to extract the oil. They also both, once the drilling is done, require heat. 
3) Describe one key difference between the process used to get oil from tar sands and the process used to get oil from oil shale.
      One difference between extracting oil from oil shale and from tar sand is that when extracting oil from tar sand it only requires steam to heat it whereas, extracting oil from oil shale it requires drilling heater holes about 7,000 feet down and that can get dangerous. 

4) Explain, in terms of EROI, why the author believes "off-shore oil drilling may be a smart way to actually reduce greenhouse gas emissions in the long run".
The author thinks that drilling off shore will reduce greenhouse gas emissions because 

5) Use EROI/Best First Principle to explain one decision that you have made in your day-to-day life. This could literally be anything, but I am looking for new examples other than the energy resources we have been studying. In other words, you should provide an example of how EROI influenced a decision at your individual level rather than the societal level.
