FOSSIL FUELS Coal, Oil, and Natural Gas By: Andrea S.
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
Heat Electricity (50% from coal) One of cheapest ways 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
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 Gas Companies in B.C. Montney Formation 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
