One pound (lb) of bituminous coal contains 12,000 BTUs of energy. Suppose a coal-fired power plant needs 3,400 BTU's of heat to produce one kilowatt-hour of electricity. This plant has a 1 Megawatt output.

a) How much coal is required to produce one kilowatt-hour of electricity?

b) How much coal must be burned to keep the plant at full output for 24 hours?

c) Assuming the coal is 2% sulfur by mass, how many pounds of sulfur would be released in a 24 hour period?
