    I have recently heard a lot about geothermal energy as a feasible energy source in the near future. I also hear that the cost and technology barriers of geothermal are holding it back from taking over as one of the main sources of domestic energy. Does anyone know more about this subject? Thank you in advance...

    Can Geothermal Power Compete with Coal on Price?: Scientific American

    Although the environmental benefits of burning less fossil fuel by using renewable sources of energy—such as geothermal, hydropower, solar and wind—are clear, there's been a serious roadblock in their adoption: cost per kilowatt-hour.

    That barrier may be opening, however—at least for one of these sources. Two recent reports, among others, suggest that geothermal may actually be cheaper than every other source, including coal. Geothermal power plants work by pumping hot water from deep beneath Earth's surface, which can either be used to turn steam turbines directly or to heat a second, more volatile liquid such as isobutane (which then turns a steam turbine).

    I think this is a great idea if we can get it done right(ie cost effective)

    Even the Evil George Bush thinks this is a good idea and uses it in his own home snopes.com: A Tale of Two Houses

    geothermal is weak power and non renewable.

    geothermal plants do not produce the power to smelt the metals they consume hence you need another power source to produce the metal that a geothermal plant consumes. That consumes as in the day to day operation, further geothermal does not have the power to make all the metal needed in the construction of geothermal.

    geothermal is the most expensive for a reason, its garbage.

    Study the history of commercial hydrocarbon development. If you don't like what you see then you're waisting your time.
