Contains most CO2 per BTU (British thermal unit: 1 BTU = 1055 Joules) making coal the largest contributor to global warming.
severe safety issues: environmental, social, and health
Devastation of the area around coal mines

2 types:
metallurgical
steam
largest reserves - 200 years
distribution: 25 states
electricity (93%):
39% of total electricity in US
~560 power plants
declining since 2007
other uses:
industry: cement, steel production
heating
some industries are trying to get out of coal:
selling plants
shutting down plants
exports vs. imports
2008
2040: 32% of energy (vs. original 42%).
30.1% of all energy
40% of electricity
70% of steel production

colonists
Industrial Revolution
mass production: a worldwide source of energy
rise of environmentalism
slow decline of use + development of new technologies
water:
large quantities used
pollutants in discharge from plants
solid waste - ash:
deposited vs. recycled
additional transportation system adds to air pollution
abundant, but will eventually run out
mining:
health difficulties
dangerous
dirty coal - pollution
preparation plants are used to clean coal
can be converted to liquid or gas but technology not ready, expensive
Overview:
1. mined
2. impurities removed
3. transported
4. converted into electricity
Abundant
Process:
1. Powdered coal burned in combustion chamber
2. Resultant heat energy produces steam
3. Steam (pressurized) rotates turbine
4. Causes rotation of coiled wires in
new forms and uses, though not fully developed and/or too expensive
Helps poor countries to rise in the industry
strong magnetic field: produces voltage
5. Electricity generated bc voltage
produces electron movement
