Electricity
causes pollution
This chart shows where the U.S. gets its
electricity. Note that most of it was from burning
coal. (Source: Department
of Energy)
How much pollution?
Here's a calculator which will show you
how
much pollution is created from your electrical
use. The typical home accounts for more
pollution than the typical car.

I purchased a Kill-A-Watt meter to do some
testing a while back after reading your
pages. I couldn't believe it when it
showed that old fridge in the basement (GE
model from the early 80's) was using 6.13
khw per day ! I purchased a new fridge to
replace that old GE unit , bought and
installed few timers throughout the house
and stopped leaving my PC on 24/7. The
result is a 20% reduction in kwh usage for
a 33 day monthly cycle. I am now down in
the low 400's (415 to be exact) for
consumption which is the lowest ever since
I moved into this house in 1996. My next
purchase will be a tankless gas water
heater to replace the 33 gallon unit I
have now.

Just wanted to thank you for the page
on Electricity usage. It helped my
roommates and I get an estimate of how
much our four computers ate up each
month. Your page settled a huge
argument, Thanks.

I came across your site when I "asked
Jeeves": How much electricity does my
computer use? Simple question, right?!
Well, 5+ pages later I finally got the
answer - on your site!! All your
information is very simple and
exceptionally useful - my thrifty husband
will especially appreciate it! ;) Thanks
again for an easy to use, informative
site. I will bookmark
it!

This information is of limited practical value
I provide the following information because
readers have asked for it, not because I think it's
particularly useful. Nothing below will help you save
electricity or save money on your electric bill. And
while it's important to know that electricity generation
creates pollution, since that's one reason you should
save electricity, it's not important to know exactly how
many pounds of coal are required to create a
kilowatt-hour of electric. If you're interested in
pollution then this
pollution calculator is much more helpful.
Kilowatt-Hours
Electrical power is measured in kilowatt-hours,
abbreviated kWh. See the What's a
kilowatt? section for more.
Coal
Sources conflict on the number of pounds of coal
to create a kWh of electricity:
Transmission and distribution losses are estimated to
be 7.2% (source),
so our adjusted figures would be 2.25, 1.18, and 0.86
lbs. per kWh respectively.
An average household uses around 920 kWh/mo. If they
got all their electricity from burning coal, that's 2070
to 791 pounds of coal per month.
Water
(Hydro/Hydroelectricity/Hydropower)
According to El
Paso Electric it takes 800 gallons of water to make 1
megawatt-hour of electricity (1000 kWh).
Nuclear
(Hydro/Hydroelectricity/Hydropower)
According to Austin
Energy, the Southwest Project nuclear power plant
generates 2500 MW (megawatts) of electricity.
Oil & Natural Gas
I haven't been able to track down this
information.
Figures available from Baywinds
suggest that 0.03 therms of natural gas contains the same
amount of energy as one kWh of electricity, but it would
take somewhat more than 0.03 therms to generate 1 kWh of
electricity because of the inefficiency of the conversion
process, and I don't know how much extra gas is required
due to the inefficiency.
Pollution calculator
This
calculator will tell you how much pollution (sulphur
dioxide, volatile organic compounds, etc.) is caused by
your electrical use.
