How much power does a 120v 15A lighted switch use anyway? - Page 10

 


  1/100 of 98 is .98.  That would mean KWH per year is 2.2 times .98,
which is 2.156.

You guys have cheap electricity!

I just pulled out my California PG&E bill to check the numbers (I can't
believe you guys pay only a dime per Kwh!!!!!. Lucky you!)

My baseline is 365.4Kwh at 12¢/Kwh
Then for 101% to 130% of baseline, it's 14¢/Kwh.
For 131% to 200%, it's 29¢/Kwh.
And, for the last few weeks of the month, at 201% to 300% of baseline, it's
43¢/month.

I averaged this to about 35¢/Kwh because I didn't know how to do the math
otherwise (I used over 150 Kwh at the 131% to 200% rate and 256 Kwh at the
29¢ rate).

.1W/bulb x 12switches x 20hours/day x 365days/year x 35¢/Kwh x 1Kwh/1000KW
= $3.00/year

It would be nice to see what others pay for 201% to 300% over baseline 'cuz
if it's 10¢, you have the deal of the century!

Well in the UK we pay around $0.25/Kwh.  Plus a fixed "meter rental".
Massive rises forecast for the near future.  To pay for our
replacement nuclear power stations.
The upside is our electrical appliances are more efficient.v  They
need to be.

My electricity bill is about $100/month on average. However I have no
gas/oil bill my house is zero heat needed.

in our area, the rate during the day is 2x the rate for nighttime or
weekends, so we try to schedule our heavy usage for off peak. nighttime
rates are in the .07kwh range.

i run a couple of kilns, at about 8kh each, which can run for 2-3 days
straight, so i couldn't afford to live in ca.

however, i just installed a 7.5kw pv cell array, so my day costs are 0.
