Collapse of Fossil Fuels

As of 2015-03-17, the Canadian tar sands need to sell for at least $100 a barrel or it does not pay to extract it. Arctic oil which Canada and Russia are researching will have an even higher break-even point. Already Australian coal is down to $72 a ton. It no longer pays to dig it up. The price of oil has dropped to $63 a barrel. Fossil fuels are already on the ropes. Why?
