ENERGY RESOURCE NOTES
TYPES OF RESOURCES
1.
Renewable Resource
: a resource that can be replaced in nature at a rate
Examples
:
air
trees
2.
Nonrenewable Resource
:
Examples
:
fossil
fuels
gold
iron
limestone
LIFE CYCLE OF COAL
peat
: mainly decaying
lignite
: soft, brown coal
bituminous
: soft coal (good energy source, pollutes the air)
anthracite
: hard coal;
PETROLEUM (Latin: rock oil)
2 Primary uses
–
Building
–
produces plastics, fabrics, synthetic vitamins, shampoos, makeup, and
much more.
Burning
–
See Life Cycle of Liquid Petroleum Chart
Environmental Impact of processing of petroleum:
Possible transportation accidents
Offshore drilling rig accidents
Energy used in pumping and refining causes pollution
Final burning releases CO and CO2 into air
Global warming?
Air pollution
Availability of Fossil Fuels...
In many cases, the countries that consume large amounts of fossil fuels have
very limited re
serves of their own.
