Why does Alberta yearn for the coal mines?

Canada's National Observer

This is how corporate bullies get their way. Alberta’s energy regulator last week approved coal exploration plans by Australian-based Northback Holdings on Grassy Mountain in the Crowsnest Pass region. The approval came after a consortium of powerful coal mining companies sued the Alberta government for more than $15 billion over losses they claim were incurred when the province imposed a mining moratorium in the area. Northback is not part of the joint lawsuit, but it too filed a claim against the Alberta government that will be heard separately. Story here.
