Tar sands are the most land wasteful, all around filthy, horrible for the environment, life-threatening form of energy in existence right now. Here's why I say that:
What are tar sands?
Tar sands, or oil sands, are a mixture of mostly sand, clay, water, and bitumen, which is what all the fuss – and filthy, water polluting, soil polluting, toxic process – is about. Bitumen is made of the same molecules as liquid oil and the same fossil fuel products are made from it.
What is so bad about tar sands?
The process of getting the bitumen out of the tar sand is complicated, filthy, dangerous, and expensive. Far more so than drilling for liquid oil, which is bad enough.
The two ways of mining bitumen:
1) Surface mining: The tar sands are collected, transported to a refinery, and the bitumen is separated from it.
2) "In-situ" mining: Bitumen is changed into liquid state by heating it with steam, underground, where it occurs naturally.
Obviously, because so much processing has to happen to refine it to the liquid oil state, there are more carbon dioxide emissions (15% more) than conventional oil. Because more and more "in-situ" mining is necessary, to get at bitumen deeper in the earth, those dangerous emissions are likely to increase. Both of these methods create more pollution than liquid oil.
