EROI

1.) We should extract oil from tar sands first because they have a higher EROEI than oil shale.
2.) One similarity between the process used to get oil from shale and the process used to extract oil from tar sands is the use of heat. Heat causes the kerogen in oil shale to form crude oil and natural gas while it used in the tar sands to extract bitumen, which is further refned.
3.) A key difference between the process that is used to get oil from shale and the process used to get oil from tar sands is, the bitumen extracted from the tar sands needs to be upgraded with either methane or hydrogen from more natural gas in order to be refined further. With the process used to get oil from shale, adding another substance is not needed for refining the crude oil and natural gas derived from it.
4.) The author believes that offshore drilling will decrease greenhouse gas emissions in the future because he believes that restricting drilling will make oil more expensive, making it more economically viable to exploit low EROEI fuel sources. This will cause more greenhouse gases to be produced to extract these low EROEI fuels in addition to the greenhouse gases produced when these low EROEI fuels are used. The author also believes that restricting drilling will increase our demand for foreign fuels who may not be carbon efficient as us. The author believes these effects of restricting offshore drilling would produce more greenhouse gases than offshore drilling itself.
5.) I eat food to gain energy. I gain more calories (energy) than the calories (energy) used to eat the food and exploit the energy from it. If there was less calories in the food I ate than the amount of calories I needed to eat and digest that food, I would die.
