One of the amazing sources of energy generation
is the incredible geothermal source. As we explore
the continental crust, temperatures
increase about 30 degrees C per km.
A wonderful description of the source
of heat controversy is presented in
Hancock and Skinner who suggest
two different heat gradients in the
core and the mantle. They present
the possible heat source as
radiogenic due to the decay of U-235,
U-238, Th-232 and K-40.
Recent reports suggest the impact of
geothermal energy fracturing subsurface
formations as effecting earthquakes
in CA, Germany and Switzerland. But
geothermal generation of energy is
a deeper, no pun intended, problem.
Issues including material balance (water)
and radioactive waste need to be
Broad interdisciplinary chemistry will
be essential in discovering how to best
tap this resource. (geochemistry,
