Coal is one of the most abundant fossil fuels in the world and can be found in 70 countries, with Canada’s coal deposits ranking 13th largest in the world. More specifically, about 85% of all Canadian coal deposits are located in Alberta and British Columbia.
The essential ingredient in coal is carbon. The carbon was squeezed from vegetation that was buried beneath soil millions of years ago through natural processes which subsequently compressed and heated up, essentially cooking the carbon and creating coal. Major commercial coal exploitation, as we know it today, did not begin until the late 1700s/early 1800s. The use of coal picked up with the Canadian Pacific Railway and the first large-scale coal mine in Alberta, the Galt mine, opened in 1882.
In 2016, only 9 coal mines and 18 coal-fired electricity generators remained. However, coal still accounts for approximately 43% of power generation capacity in the province.
This source of Alberta power is changing. There is new focus phasing out coal-fired generators and replace them with natural gas and renewable energy. The most recent updates indicate that coal is set to be phased out by 2023 in the province.  Coal production will be affected in particular by those projects that work to green the grid or get Albertan electricity from somewhere other than coal.
