Yes Abd ul-Rahman,
I did a double-take this morning when reading the original post
mentioning the slowing of the earth's rotation due to wave/tidal power
generation. If such were true one would have to ask, would wind power not also
slow the earth's rotation? I have never heard of any argument for either on
even the smallest measures (from scientist's anyway), but I am no expert on
either system.
Just a thought, would solar power (to the nth degree) reduce or
increase the ambient earth temperature? I would have thought it would cool not
warm. It would reroute that natural solar heat from the earth's thermal systems
to a man-made system and insulate it from the surrounding environment, thus
reducing the earth's temperatures. It would not actually be removed from the
earth's thermodynamics but it would be rerouted and isolated from the natural
system. That was my thought anyway.
Sincerely,

I don't think this is correct. The source of tidal energy is primarily the
moon. The kinetic energy of the moon in orbit around the earth is pretty
large.... I doubt that tidal power generation systems would ever be used on
a scale such as to make a measurable difference in the moon's orbit, given
all the alternatives, including direct solar power.
