We should be doing everything achievable to develop geothermal free energy technologies. Though largely untapped, this form of energy has immense possibilities and it is created from the earth itself. There is huger amount of free energy lying just below the surface of the earth on which we live, and saddling it is the greatest job.

The temperature at the center of the earth is 60 times greater than the boiling point of water and the heat emanating from it make pressures which can be felt only a few miles under the surface of the earth. These pressures contain huge amounts of free energy and superheated fluids in the form of magma, which we see in the power and energy of whenever there is a volcanic eruption. These fluids also filter to the surface as steam and come forth from vents.

We could also make these vents and simultaneously build appropriate chambers where the magma can be held for later conversion to free energy, which would produce electricity to light or heat up our homes. A geothermal plant can be created if we dig a well on the ground where there is a rich source of magma or hot fluid, then fit the well with a pipe which would pump up the hot fluid to ground level for the production of required steam. The steam would turn a turbine, which would produce the electricity.

There is lots of skepticism regarding the tapping geo-thermal free energy sources, which is preventing large-scale production of this free energy. Critics claim that finding the right area for tapping these resources would be cost-prohibitive as well as time-consuming. Then there is more great expense required to build a geo-thermal power station, and there is no promise of the plant turning a profit. It might so happen that a geo-thermal site becomes incapable of producing enough steam which makes it unfeasible and unreliable.

Several conservationists are of the opinion that when you bring out magma, it is feasible that some dangerous materials also accompany it. However the benefits of geothermal energy far outweighs such comments if only we explored it deeper. We must realize that since the root of the energy is the earth, it can never carry any contaminant. geo-thermal energy is an cost-efficient free energy source - easy to produce after site identification and the set up of the plant to develop it.

A geo-thermal plant is also not as huge as say a dam or an atomic free energy unit, making it a lesser risk to the environs. Using this alternate source of free energy would naturally reduce our dependency on fossil fuels. Perhaps most importantly of all, we are never, ever going to run out of geothermic energy, and it is not a commodity that would forever become more costly in terms of real dollars as time passes, since it is naturally occurring. The use of geothermal free energy would be extremely inexpensive and the cost of creating a power station can be recovered expeditiously.
