response to JPZiller:  Dear News Sentinel, it is incorrect to
write 'megawatts of energy.' A megawatt is a unit of power, a
megawatt/hour is the unit for energy.   Watt is not the unit for
energy, it's the unit for energy USE (or production). Joule is
the unit for energy. Consequently Watt is Joule per second. So
Watts of energy is sloppy indeed, but it does tell you that
(mega)Joules are produced per second. And that's the defining
characteristic of a powerplant: how much electric energy it can
produce per second.  Therefore (mega)Watt*hour (and not
Watt/hour!) is the total energy used and that's why your bill
reads in (kilo)Watt*hour.
