ISCI 1001 – Lecture 23
Fossil Fuels:
- Coal
- Crude oil
- Oil shale
- Natural Bitumen & Extra Heavy Oil
- Natural Gas
Coal Types:
- Anthracite (hardest coal, highest energy content)
- Bituminous (lower energy content, used in steel & electricity production)
- Sub-bituminous (softer, higher water content, electricity production)
- Lignite -> lowest E content (electricity production)

- All 4 boxes -> resources
oSub-Economic, Economic, Undiscovered, Discovered
- Econ./Disc. -> use -> reserve
World Coal Reserves (end of 2008):
- 860 billion tonnes
- 405 – bituminous (includes anthracite)
- 260 – sub-bituminous
- 195 – lignite
Coal Energies:
- Anthracite: 29-31 MJ/kg (~859% C)
- Bituminous: 28-29 MJ/kg (~809% C)
- Lignites: 8-20 MJ/kg (~65% C)
Coal Resources & Reserves (Energy):
- Resources 200 ZJ
- Reserves (2005) 20 ZJ
- Total World primary E consumption
o2005: 461.428 QUAD (486 EJ)
Quad -> quadrillion BTU
o2008: 492.587
- Canada primary E consumption:
o2005: 14.164 Quad (14.9 EJ)
o2008: 14.029 Quad
- M (mega) = 106
