Because none of them are as cheap and efficient as burning fossil fuels, whether its coal, oil, or gas.

But the problem with cost and efficiency is that people won't buy it if its not cheap and effective.
San Ramon, Calif.-based Chevron said the well set a variety of records, including the deepest well successfully tested in the Gulf of Mexico. Chevron said the well was drilled more than 20,000 feet under the sea floor below 7,000 feet of water for a total depth of 28,175 feet.

Great question. Why not answer it and become rich by constructing geothermal plants all over the world?

Coal $0.0531 per kwh
Wind $0.0558 per kwh, or 1.051x coal
Natural Gas $0.0525 per kwh, or .98x coal
Nuclear $0.0593 per kwh, or 1.12x coal
Solar $0.30 per kwh, or 5.65x coal
Biomass $0.075 per kwh, or 1.41x coal
Geothermal $0.075 per kwh, or 1.41x coal
How much does geothermal energy cost per kilowatt-hour (kWh)?
Answer: A power plant built today would probably require about $0.05 per kWh.
What does it cost to develop a geothermal power plant?
Answer: Costs of a geothermal plant are heavily weighted toward early expenses, rather than fuel to keep them running. Well drilling and pipeline construction occur first, followed by resource analysis of the drilling information. Next is design of the actual plant. Power plant construction is usually completed concurrent with final field development. The initial cost for the field and power plant is around $2500 per installed kW in the U.S., probably $3000 to $5000/kWe for a small (

A word on price of geothermal. There is some dispute apparently.
That means the coal plant is $1,350,000 cheaper. But for how long?
At a savings of 2 cents per kilowatt hour for the geothermal power, times 500 kilowatt capacity, you make up 10 dollars an hour with the geothermal plant. That means it will take 135,000 hours for the goethermal plant to pay for itself (assuming that the price of coal doesn't go up). 15.4 years if the plant is being run at full capacity full time. Obviously that's not practical but that gives you a baseline.
So realistically, in may places, geothermal stabilizes prices immediately, helps the environment immediately, hurts the saudis immediately (i realize the saudis are producing oil, not coal, but oil is also used, and its even more expensive than coal) and starts yielding a net profit in less than 10 years.
