Much better having just the waste heat from the USE of power, rather than
the waste heat from generation, also. Something like 40% of the fuel energy
is wasted before any electricity is produced - even with nuclear plants.
This alone should allow growth of power use without adding to the present
burden. This is of course not a long-term solution, but would help in the
interim. The loss of all those pollution and greenhouse gas sources cannot
