Approaching comparing apple to oranges here, so I have to agree with
Kirk. The loss associated with the transportation of electrical power
are known expected loss, loss that little can be done to prevent. The
loss of water in the transportation of the water in this example is due

Hey Doug,
Good point, the majority of coal plants are in the 40% ballpark, but I
was being generous and including the combined cycle coal-fired plants.
I've been to one in Columbia, SC that achieves 50% from coal. It
also uses cool water from the bottom of the lake for cooling, so that
increases
You're over-optimistic. A really good, modern coal fired power plant
gives 40% thermal efficeicnecy at a high power rating. The line and
transformer losses come after that. A combined-cycle natural gas fired
plant (gas turbiine with a steam turbine working off the turbine exhaust
gases ) will g
yes, but they represent reasonable engineering. The water mains are deferred
maintenance. A different kind of engineering I suppose.

Funny thing, that's not funny is, about 50% of the energy contained in
coal makes it to the power outlet.
The rest is lost to heat loss, line losses and transformer losses.
