Pro Coal
by Andre Martin ‘06
• Abundant domestic supplies
• The most competitively priced sources
• Ash, Sulfur, Nitrogen and other metal emissions have been
reduced because of the Clean Air Act. Keep in mind it has not been
eliminated.
• Coal produces 62% of the worlds energy
• For the US Coal produces 37% of the energy
• It is Number 1 in the US pertaining to the source of power
which accounts for more than half all electricity.
• In past half century prices have dropped 44 %
• Efficiency is now higher than ever dealing with the National
Coal council. Efficiency is at 40%
• Production and consumption is growing fast.
• If the efficiency goes as planned the efficiency can reach
up to 50 – 55% within 10 years
• Many Coal fired plants are nearing retirement so that is
providing space for clean-coal technology
Today I would like to talk to you about the wonders of coal. Now,
I know there are many of you in this room right now that have negative
things to say about coal but I am going to ask you to put your feelings
aside and keep an open mind. The first important aspect to look
at with coal is that it is a necessity for life as we know right
now. Coal is primarily used to produce electricity and is now the
worlds top energy supplier. The world’s consumption of coal
is now 5,800 million short tons annually. 75% of that coal is used
for electricity. If you don’t know how electricity is produced
from coal I will tell you.
When coal is used for electricity it is crushed and pounded. Then
it is burned. The heat is then used and transferred into steam.
The steam is then used to spin turbines that turn generators and
create electricity.
One of the main problems however with coal is its emissions. Well
what about the carbon dioxide that is in the air. It is killing
many people. Well I have news for you. Ash, Sulfur, Nitrogen, and
other metals have been reduced over time because of the Clean Air
Act
• The United States Congress passed the Clean Air Act in 1963,
the Clean Air Act Amendment in 1966, the Clean Air Act Extension
in 1970, and Clean Air Act Amendments in 1977 and 1990. Numerous
state governments and local governments have enacted similar legislation,
either implementing federal programs or filling in locally important
gaps in federal programs.
Once again I would like to state that coal is currently the No.
1 U.S. source of power. In past half-century prices have dropped
44 percent in real dollars which is rather impressive considering
the state that we are in now with rising oil prices. Efficiencies
are also as high as 40 percent according to the National Coal Council.
"Clean coal" technologies developed during past 15 years
has helped reduce pollutants.
The production and consumption of coal is steadily growing and the
coal industry claims efficiencies could reach 50 to 55 percent within
10 years. Many coal-fired power plants are being destroyed slowly,
so in proportion with the clean-coal technologies and higher efficiencies,
these numbers should grow. In past six months about 20 have been
announced.
To recap all of the major pros of coal
1. There is an abundant domestic supply
2. Ash, Sulfur, Nitrogen, and metal emissions are reducing steadily
3. # 1. source of power for the US
4. Substantially getting better as the years go on
