Geothermal Power as Alternative Energy
We should be doing everything possible to develop geothermal
energy technologies. This is a largely untapped area of
tremendous alternative energy potential, as it simply taps the
energy being naturally produced by the Earth herself. Vast
amounts of power are present below the surface crust on which
we move and have our being. All we need do is tap into it and
harness it.
At the Earths' core, the temperature is 60 times greater
than that of water being boiled. The tremendous heat creates
pressures that exert themselves only a couple of miles below
us, and these pressures contain huge amounts of energy.
Superheated fluids in the form of magma, which we see the power
and energy of whenever there is a volcanic eruption,
await our tapping. These fluids also trickle to the surface as
steam and emerge from vents. We can create our own vents, and
we can create out own containment chambers for the magma and
convert all of this energy into electricity to light and heat
our homes. In the creation of a geothermal power plant, a well
would be dug where there is a good source of magma or heated
fluid. Piping would be fitted down into the source, and
the fluids forced to the surface to produce the needed steam.
The steam would turn a turbine engine, which would generate the
electricity.
There are criticisms of geothermal energy tapping which
prevent its being implemented on the large scale which it
should be. Critics say that study and research to find a
resourceful area is too costly and takes up too much time. Then
there is more great expense needed to build a geothermal power
plant, and there is no promise of the plant turning a profit.
Some geothermal sites, once tapped, might be found to not
produce a large enough amount of steam for the power plant to
be viable or reliable. And we hear from the environmentalists
who worry that bringing up magma can bring up potentially
harmful materials along with it.
However, the great benefits of geothermal energy would
subsume these criticisms if only we would explore it more. The
fact that geothermal energy is merely the energy of the Earth
herself means it does not produce any pollutants. Geothermal
energy is extremely efficient—the efforts needed to channel it
are minimal after a site is found and a plant is set up.
Geothermal plants, furthermore, do not need to be as large as
electrical plants, giant dams, or atomic energy facilities—the
environment would thus be less disrupted. And, needless to say,
it is an alternative form of energy—using it would mean we
become that much less dependent on oil and coal. Perhaps most
importantly of all—we are never, ever going to run out of
geothermal energy, and it is not a commodity that would
continuously become more expensive in terms of real dollars as
time passes, since it is ubiquitous. Geothermal energy would
be, in the end, very cheap, after investigation and power plant
building costs are recouped.
