definition • Non-renewable- any natural resource that cannotbe replenished by natural means at the same rates that it is consumed Examples?
COAL • How mined? • Surface • Underground • Longwall
COAL • Processing steps • Washed • crushed
COAL • uses
coal advantages disadvantages Produces CO2 when burned Produces ash- must be disposed of • Plentiful in US • inexpensive
OIL • How mined? • Drilled • Pumped out • Into pipeline
OIL Processing (refining) steps: Boiled Separates based on boiling point and density
Oil Advantages disadvantages Emits CO2 rely on foreign sources Oil spills • High heating value • Abundant • Easy to refine
NATURAL GAS • How mined? • Fracking • Force chemical laden water thru fractures and breaks up shale • Releases oil and gas
Processing (refining) • Removes impurities • Mainly sulfur
Natural Gas advantages diadvantages Hard to recover from ground Contaminate groundwater? • Burns cleaner • Inexpensive • No ash • High heating value
NUCLEAR • Uranium mining • Surface mining (mostly)
Uranium processing • Crush • Purified • Dried • Yellow cake • Enriched to concentrate
Uranium uses? • Nuclear power plants (electricity) • Nuclear weapons
nuclear • Advantages • No emissions • Cost efficient • Disadvantages • Radioactivity • Nuclear waste • Plants expensive to build
