Tar Sands and EROI


  1. We should extract tar sands first as the EROI is 5 and the EROI is 3 - this means you get more energy per a single unit of energy
  2. Both require heat to get the oil into its final form.  Heat added in oil shale turns the oil shale into crude oil and natural gas - heat added to tar sands extracts the oil from within the sand.
  3. The major difference between getting oil from oil shale and tar sands is that you get more oil from tar sands.  When extracting oil from oil shale, natural gas is a byproduct of the process.
  4. With off-shore drilling there is a much higher EROI and therefore you get more oil and have to use less fossil fuels to get it.  In the long run, this means we produce more oil without having to use as much oil/ fossil fuels to get it - this results in lower rates of CO2 pollution
  5. When searching for food in my house I first look for junk food or something I can consume quickly with little to no work.  My last choice is having to make food as it takes a lot more time and work to get the food.
