PV & Global Warming [RE-wrenches]

[Eric Smiley]

CO2 emmisions in the US for 1999:

Output Rate (pounds CO2 per kWh)
Coal . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .2.095
Petroleum . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1.969

In LA an optimally oriented array should produce about 1400 kWh/kWpeak
of PV (Source: A Simplified Guide to PV System Design and Installation,

Therefore:
(pounds of CO2 offset per year per kWpeak of PV)

Coal. . . . .2933
Petroleum . .2757
Gas . . . . .1849

Average . . .1877
