Ch 14 & 15: Fuel + Energy
Fossil Fuels
Burning of fossil fuels creates combustion in cars and heat when burned in homes.
Combustion ~ thermal energy
Collection of fossil fuels (coal & natural gas)
Begin to burn the fuels (boils water creates steam)
Steam moves turbine (mechanical energy)
Turbine powered generators (changes the mechanical energy to electrical energy)
Sustainable
Movement of water, wind, or solar heat has the ability to transfer mechanical energy into electrical energy
Movement ~ mechanical energy
No heat
No harm to environment
Greenhouse gasses
Coal
Coal power ~ electricity
91% of coal used for this
Surface / strip
Undergrounds
Environmental Costs
Global climate crisis
Air pollution
Acid mine drainage (pyrite acidic mineral = exposed to surface oxygen)
Coal refuse and combustion by products
Natural gas
Mostly made up of methane
Gaining popularity in the US ~ due to the ease of collection
Used for
Heating
Cars
Synthetic oil
Oil
Petroleum oil: liquid viscous mixture of combustible hydrocarbons
Fractional distillation
Oil Shale
Mostly undeveloped until oil prices rise greatly
1 ton oil shale = 1 barrel of oil
Oil Sands
Commercial development has begun
Extensive environmental damage
