Unlike oil and gas, electricity is not a primary source of energy. It needs to be manufactured from other energy sources.
In Alberta, coal (65.79%) and natural gas (26.47%) are the main sources. Biomass and other alternatives account for 2.86%, while hydro and wind together make up 4.85% of the total.  Alberta has no nuclear power plants.
Alberta produces virtually all of its own electricity needs. See Alberta's production statistics here.
In 2010, production
consumed 792,864,200 GJ and
emitted 53,135,950 GHG tonnes.
