Mining and Oil and Gas Extraction
Energy is a key driver of Alberta's economy. The province's oil sands are the third largest proven crude oil reserve in the world, after Saudi Arabia and Venezuela. Only about 3.4% of these oil sands can be mined. The remaining reserves are too deep and must be extracted by other methods. In 2014, the province also produced 33.8 million tonnes of raw coal-enough to fill Calgary's Saddledome every two days. Alberta also produces about 67.0% of Canada's natural gas.
