Default Coal Vs Gas as a power source .

I had been thinking that at some point the plunging price of coal might
make investing in coal mines a wise choice , now I am not so sure .

Apparently gas driven ''Combined-Cycle Power Plants'' are a supper
efficient alternative and gas is now very cheap . More reading needed .

If anyone has cost comparison data please do make a post .


Quote:
A combined-cycle power plant uses both a gas and a steam turbine
together to produce up to 50 percent more electricity from the same
fuel than a traditional simple-cycle plant. The waste heat from the
gas turbine is routed to the nearby steam turbine, which generates
extra power
