Reducing Energy Use

From: andrew cooke <andrew@...>

Over the last 3-4 years we've reduced our electricity use from about 270KWh to
170KWh a month.  That's a reduction of 37%.  As far as I can tell it comes
from:

 - A more efficient fridge
 - Getting rid of the TV
 - Changing to a more efficient main computer
 - Turning off the laser printer

170KWh a month still means that we're burning electricity at an average rate
of 236W.  I don't know what's the main culprit now - I should try find a power
meter (or turn everything off and use the supply meter one at a time, I
guess).

Hi,

170kWh that's exactly where we are, with two laptops, a decent fridge =
and two cups of coffee brewed  every morning with the help of an =
electric kettle. I believe the fridge is the number one consumer but the =
kitchen was fully equipped and I cannot change it. There is also the =
wifi router, which always feels a little too warm. I don't see much room =
for improvement from there unless I move the fridge outside onto the =
cool fire escape during winter. =46rom a certain point, saving more =
means to impose such a strict regime on the use of all devices - meaning =
to turn off the monitor every time one walks away, shutting down the =
wifi whenever one leaves the apartment, minimize fridge door openings - =
that it simply becomes impractical.
