PG&E Info
A speaker from PG&E's Pacific Energy Center came in for a talk today, I gleaned some handy take-away bits and bobs:
PG&E is 31% renewable (a mix of small renewables and large hydro; <1% is photovoltaics); 20% is nuclear. Lots of natural gas (about equal to renewables total), and a sliver of coal.
Pacific Energy Center:
Water Conservation class (free, no registration) on 3/24
Most classes require registration, at http://www.pge.com/energyclasses
Other links:
http://www.wecandothis.com
http://www.csi-trigger.com (for PV rebate rates)
PG&E offers an insulation rebate of $0.15/square foot. This will be discontinued in 2011, probably.
Windows:
U-value of 1 is equal to a wall; SHGC value of 1 is equal to a hole in your wall.
SHGC of 0.32 is good for commercial buildings in CA climate
It may be that in desert-like areas of CA, a first generation Low-E window with tree shading outside is more effective than a 2nd generation Low-E window.
Fridge:
Typically 400kWh/year (was 2000 kWh/year in 1970).
Should aim for 10 year replacement cycle
