Chapter 14: Fossil Fuels
Coal
Dominant source in 1800s-1940
Dirty fuel
How to get it:
Derived from mining
Surface/strip
Underground
Environmental issues
Acid mine drainage
Air pollution
Coal refuse
Coal combustion products
Bottom ash
Boiler slag
Flue gas desulfurization material
Fly ash
Oil
Petroleum oil: liquid, viscous mixture of combustible hydrocarbons
Internal combustion engines
Oil drilling
Oil refinement
Recovery methods:
Primary: Conventional pumping without additives
Secondary: Pumped using brine or steam
Enhanced: Pumping CO2
Consequences
Costs of purchase
Political instability in the Mid Easr
Environmental issues
Resource limitations
Natural gas
Methane
Clean fuel
combustible gas (mostly methane) extracted from geologic strata
Increased popularity and usage
Fossil fuel-power generator
Extract fuel-fossil fuel, water, wind, etc.
Fuel source is heated and used to boil water
Steam is then generated and is pumped over to turbine causing it to spin (mechanical energy)
Generator then converts mechanical energy into electrical energy
Some energy is lost as heat
Now we have electrical energy which is distributed across the electrical grid system to power lines which power our community
Energy security
Threats
Oil dependence
Terrorism
Global climate change
Supply vs demand
