RE: (ET) conversions

["Elie, Larry (L.D.)" <lelie ford com>]

Kilo-Watts are 1,000's of Watts; 1 KW= 1,000 W.

A Watt-Hour is 1 Watt used for 1 Hour.  A Kilo-Watt-Hour is 1,000 Watts 
used for 1 Hour, or 1,000 Watts used for 1 Hour, or any other combination 
of Watts times hours that equals 1000.  It's just the product of the Power 
Load (Watts & KW are units of Power) times the number of hours used.

A 60 Watt light bulb used for 1000 hours is 60000 Watt-Hours or 60 KW 
Hours.  A year is 8760 Hours.  If I use my 60 Watt bulb for 1000 hours of 
the 8760 hours of the year, my Duty Cycle is the % of that time used, or 
11.4% Duty Cycle.  Had I used my 60 Watt bulb 100% of the time I would be 
using 525 KW-Hours.

Since we're on the subject of conversions, perhaps you all can help me
with this one:

How do I convert "kilowatt-hours per year" into just plain "watts" (like
a light bulb uses 60 watts)?
