While you have a lot of good points these ones are absolute crap.

I have been inside shut-down 200 tonne turbines and they didn't fall apart.
This is done on a regular basis to make sure they stay healthy.

Power compmaies do not turn up the voltage at nights. The voltage rises due
to less VA draw online and the line losses become a smaller factor of the
delivered voltage.

Excess generating capacity has nothing to do with voltage, at any time. The
voltages are maintained (regualted) at the generator, at the high tension
line receiving point, at the dustribution station and manually at your yard
trensfomer somtimes. The government specs are plus or minus 10% at any
voltage level.

Yes some utilities do reduce the voltage during over peak times. This is to
keep the peak load down to a manageable level to avoid having to drop
customers off, preserving the system from failures. It is still done withint
the 10% rule mandated.

 Also remember

that at night, voltage in most systems is at its highest because of the
excess generating capability, at least compared to the daytime load.  Does
having 122VAC at your outlet instead of 110VAC really translate into a
substantial emission savings?  I doubt it, but it's one of the ways power
plant operators cope with varying demand.


You can't simply shut down a 200 ton turbine:  if they aren't kept spinning
their main shafts will deform and become unbalanced and they'll shake
themselves apart.


Then there's the power factor issue to consider.  Are you really saving
money when the power company boosts the voltage at night to compensate for
the lower demand?
