5What is Electricity?http//www.safeelectricity.or
g/esw_v1_1/science/basics.htm
Electricity is the flow of electrons generated by
a Turbine which is basically a shaft with blades
at one end and electromagnets at the other. Water
or steam or some other energy source pushes the
blades, which make the shaft and the magnets spin
very fast. The magnet end is surrounded by heavy
coils of copper wire, and the spinning magnets
cause electrons in the wire to begin to move,
creating the flow of electrons we call
electricity.

9What are CCPs? Coal Combustion Productsfootnote
The DOE calls CCPs CUBs Coal Utilization

11Environmental Impact/Mitigation of CCP's
Ca released from synthetic gypsum (piled in
field above) can prevent soil crusting seen above.

Utilization Byproducts)
12Utilization of CCPs
13Fly Ash Recycled into Concrete
14Why do we care about concrete? Because it is made
from
15Why replacing cement with Fly Ash is a very good
idea!
- Four essential elements are needed to make
cement Calcium, Silicon, Aluminum and Iron.
(look familiar?) - Calcium (which is the main ingredient) can be
obtained from limestone, - Silicon can be obtained from sand and/or clay.
- Aluminum can be extracted from bauxite
- Iron from iron ore, and only small amounts are
needed.
16Reduction goals of greenhouse gas emissions from
concrete production. Each ton of fly ash that
replaces cement in concrete production reduces
greenhouse gas emissions by a ton of carbon
equivalents. In 2002, the use of fly ash in
concrete reduced emissions by over 12.5 million
tons of carbon equivalents.(www.epa.gov/epaoswer/

19Mercury Pollution
Mercury is a harmful neurotoxin that has been
found to stall the development of children's
brains, both in and out of the womb. Every year
630,000 babies are born in America with unsafe
levels of mercury in their blood. More than 40
states have issued fish advisories due to mercury
contamination in some or all their state's
waters.Coal-burning electric power plants emit
vast quantities of toxic air pollution not only
have they been found to be the largest
unregulated source of mercury pollution, but they
also emit more than 80 tons per year of lead, and
more than 70 tons per year of arsenic. From

20Mercury in our Environment
21Biological removal of mercury from coal
- Iron and sulfur eating bacteria have previously
been used for sulfur removal from coal and for
mineral mining. - The removal of mercury from coal is also possible
via the same principles. Two bacteria,
Leptospirillum ferrooxidans and Acidithiobacillus
ferrooxidans and four environmental bacterial
samples obtained from acid mine drainage were
studied for mercury removal from coal. - Four different coal samples were included in the
study preliminary results have shown that up to
20 of the mercury can be removed in batch
cultures compared to control.

Pollution
Train derailment, Lincoln Co., Nevada
Thermal pollution, Biscayne Bay, Florida
33Thermal Pollution comes from both fossil fuel and
nuclear power generation. At Turkey point, the
fossil fuel units require 1,270 cfs of cooling
water and raise the water temp. by 12ºF the
nuclear unit requires 4,250 cfs and raises the
water temperature 16ºF.

Bay 10 sq. mile canals cooling radiators for
water heated by the nuclear power plant. This
water will then be recycled.
