Given California's energy catastrophe, crisis, problem, glitch, opportunity (take your pick), EcoWorld decided to ask the following question:

If every single-family detached house in California was equipped with a photovoltaic system similar to what SMUD's Pioneer PV Program is offering, how much energy would that amount to and what would the numbers look like? (We assume with 6 million buyers the cost would drop to $5,000 per unit.)

Detached houses in California	6,800,000
Avg annual kilowatt hours used - household	7,200
Avg annual megawatt hours used - all detached houses	49,300,000
Avg annual mwh savings with photovoltaics - household	3,600
Photovoltaic system cost	$ 5,000
Price per kwh	$ .08
Annual electricity cost savings - per household	$ 288
System pay back time - years	17
Cost of systems - all - (billions of $)	$ 34.26
Cost savings - all - lifetime - (billions of $)	$ 33.55
CO2 reduction - per household - lifetime - lbs	83,800
CO2 reduction - per household - lifetime - metric tons	38
CO2 reduction - all - lifetime - (billions of lbs)	562
CO2 reduction - all - lifetime - metric tons	255,000
