[Noisebridge-discuss] PG&E Bill

[jim]

   probably good to start a lighting thread. 

   one conceptually easy fix is to separate the 
existing flourescent lights and switch each on or off 
separately. 

   we've estimated something like 1.5 Amps for each 
eight-foot fixture. also, it's possible that fixtures 
without bulbs are leaking some power. 
   i'm for LEDs but suspicious of the current crop of 
socket-ready lamps, mainly wrt mechanical aspects. 
   CFLs are probably more efficient, but we have only 
a few fixtures that'll take them. 
   note that there area bulb sockets in the ceiling 
that are likely switched--we'll have to do the PITA 
hunt to figure the wiring out. 

   maybe we can come up with a mix of LEDs for 
low-level general lighting and flourescents to 
illuminate particuar working areas. 

   as to other power aspects, the cold season is upon 
us, and it looks like "the kitchen" is coming 
together: both suggest greater power bills. 
   what's the possibility of using propane or similar 
room heaters? and what's the possibility of 
controlling the kinds of cooking and refrigeration 
appliances we add? also, we should be aware of the 
efficiencies of ventilation systems ("fart fans" in 
the toilet rooms, darkroom vent fan, others).
