FOSSIL FUELS Coal, Oil, and Natural Gas By: Andrea S.
History of Coal • Coal was used for heating by cavemen in England • During Industrial Revolution, coal used to run steam engines • 1880, started being used for generating electricity and heating
Pros and Cons • Limited supply • Air pollution • Produces most carbon dioxide when burnt (global warming) • Produces sulfur dioxide (breathing problems, contributes to acid rain) • Strip mining destroys habitats • Heat • Electricity (50% from coal) • One of cheapest ways
Coal Mines in B.C. • Coal Mountain • Elkview • Line Creek • Greenhills • Fording River • Brule • Perry Creek • Roman Mountain • Trend Mine • Quinsam Coal Mine
History of Oil • In ancient times, oil was easy to access (oil seeps on ground), used as medicine • 1850, American sold it in bottles to cure ailments • Many oil wells were drilled afterwards
Pros and Cons • Electricity • Heating • Fuel for powering motors • Boosts our economy • Easier to pump out than coal • Limited supply • Air pollution • Releases carbon dioxide (global warming) • Tanker ships can spill • Pipelines can burst • Releases sulfur dioxide (breathing problems, contributes to acid rain) • Disturbs habitats
Oil Refineries in B.C. • Burnaby Oil Refinery-largest in the province • Prince George Oil Refinery
History of Natural Gas • 400 BC, Chinese used it to boil water • 100 AD, Persian king built his kitchen around natural gas flame (struck by lightning) • 1700, British used for lighting • 1800, used in North America for lighting • 1885, used for Bunsen burners
Pros and Cons • Electricity • Heating • Liquefied for easier transportation, converted back to gas • Less pollution than coal • Can be bottled up for car fuel • Limited supply • Air pollution • Carbon dioxide (global warming) • Very flammable • Can’t see or smell • Explosions, oil spills • Disturbs ocean habitats
Natural GasCompanies in B.C. • MontneyFormation • Precision Drilling Corp. • Calfrac Well Service • Trican Well Service Ltd.
Generation Process • Fossil fuel goes to power plant • Burned in a boiler, water becomes steam • Steam goes through pipes to turbine • The steam spins the turbine blades. • Spinning blades cause shaft to turn inside generator • Electrical current is produced • Electricity travels through wires to cities
Price • Approximately 9¢/kWh • Prices expected to rise because the supply is slowly running out
