What are Resources (2 types)?
Renewable
resources –
resources replaced as
they used
– Ex. Water, plants
(trees), air, sun
Nonrenewable
Resources –
have a limited supply
– Ex. Minerals and Fossil
fuels
What are Fossil Fuels?
Fossil
Fuels – Forms of stored energy
that are remains of living things made
primarily of carbon and hydrogen through
the process of carbonization.
– Ex. coal, oil, natural gas
What is Carbonization?
Carbonization – The partial decomposition of plants
releasing gases which change the chemical composition
of the plants leaving only carbon and hydrogen.

What is Coal?
Coal-
formed
from partially
decomposed
Plant/Animal
matter, which is
turned into solid
brittle rock when
it is compressed
over a long
period of time.
Coal Facts You Should Know!
Common:
The
most abundant
fossil fuel
Compressed:5-10
ft of decomposed
material makes
about 1 ft of coal
Cheap: Less than
half the price per
million BTU than
oil and natural
gas.
Coal Fast Facts
How much power?- 1 lb. of coal can power 10-100
watt light bulbs for an hour
How much left?- Should last for about 250 years at
the current rate of use
Use decreased during the 40’s and 50’s because oil
and gas was easier to use and more available due to
WWI and WWII.
Use has been increasing since the Arab Oil Embargo of
1973.
Oil Embargo- 1973-74
News Cast
More Coal Fast Facts
It is now used mainly for
the generation of
electricity
In 2012 it was responsible
for 20% of the nation’s
energy consumption (39%
electricity)
Mostly transported by train
or barge
China is the major
producer and the U.S. is
second

Problems with Coal
Problems with Burning Coal…
Contains sulfur causing
air pollution when
burned.
Makes acid rain!
High amounts of air
pollution (CO2 and
SO2) are given off by
coal power plants.
Causes more air
pollution when burned
than any other fossil
fuel
Coal Mining
Underground mining:
– dangerous, collapsed
mines, fires, gas
explosions, and black lung
(lungs are coated in coal
dust)
Strip Mining –
– the overlying layer of rock
is stripped to get to the
coal from the surface.
– this is cheaper, safer,
and yields 3x’s more
coal than underground
mining

Problems with
Mining Coal
Less than one-half of the
mines have been
reclaimed…
restored
to their natural state
Acid Mine Drainage:
(AMD) is when water
reacts with mineral in the
open mine forming highly
acidic water pollution the
environment killing aquatic
organisms and waterfowl

Solutions to Coal Use
Mining Control and Reclamation Act of 1977 requires that mined land
be restored to its primary use (forest, field, etc.)
Clean Air Act of 1990 forces companies to reduce the emissions
(release) of SO2 and NO2 when burning coal
More coal in this country is coming from the mid-west instead of the
east because it contains less sulfur
New technologies are being invented to reduce air pollutants from
coal (scrubber - sprays the gas with lime or calcium water binding the
SO2, causing it to settle out – expensive process to install)
***Using natural gas is cleaner because it releases one-half the CO2
and SO2 of coal
Synthetic Fuels
Fuels
produced by chemically
changing fossil fuels like coal. They
are cleaner burning
