why is coal so cheap? good question. in short, it isn't. well, it is in terms of dollars per kilowatt-hour. but it's expensive in terms of deaths per kilowatt-hour. warning maths ahead. electricity is worth about $.10 per kilowatt hour. let's burn coal and produce 1 terawatt-hour of electricity. which brings in $100 million. and kills 160 people. worth about $1 million each. or $160 million total. or 60% more than what they charge for the electricity. so when you buy coal generated electricty, you're not paying for it in cash. you're paying for it in blood.
