No-one ever needs to mine coal, drill
for oil or gas, dig up and refine uranium or anything else to burn or
react: all the energy we could ever need is below our feet.
If people want to have electricity made
in big installations that can run 24 hours a day seven days a week
that do not emit any pollution, burn anything or create toxic or
dangerous waste material there is only one answer: Geothermal power
stations.
All of the technology needed to make
this work almost anywhere on the Earth's surface has already been
tried and proven.
All we need to do is drill a deep
enough hole, pump water down it and steam will return which we can
then use to generate electrical energy. The only “waste product”
is heat, which every other type of power plant (apart from
hydroelectric) creates too.
The drilling might cost something but
the hole does not close up or “run out of heat” (unlike an oil
well) and the water we sent down the well to heat up and drive the
generators can be cooled in radiators and sent back down again so
there is no need for a continuous supply of water or heat pollution
of rivers. It is cheap in terms of generating systems and safer than
any other power system (apart from maybe solar panels). All of the
generator parts are available off the shelf.
So why isn't this happenning? Why
aren't all of the countries of the world installing geothermal power
plants?
There is no technical reason why not.
