Tar sands, also called oil sands, are a type of fossil fuel deposit, which has only fairly recently been considered as feasible sources of oil.


Tar sands were rebranded "oil sands" by the oil industry as part of a public relations exercise. The Wikipedia page was moved in 2008.[1]


Large deposits exist in Canada and Venezuela, and lesser deposits have been found in Kazakhstan and Russia.


The extraction of tar sands is a matter of concern due to the large carbon footprint and the local environmental damage of the process.


Tar sands are the "high hanging fruit" - requiring a lot of energy to extract and purify. Advances in technology have gradually allowed more extraction to be energetically profitable (i.e. decreased the amount of energy required to extract tar sands).
