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.
