$0.10/kwh - May 9, 2012 submitted to Public Utilities Commission PG&E proposed new rates for charging electric cars at night

Driving a Nissan Leaf (or similarly efficient electric car)

$1.00 gallon equivalent in a 30 mpg gasoline car

ELECTRIC CARS = $1/GALLON?

Suppose 40 miles a day = 14,600 / yrVolt = 35kwh / 100 mi,

5,110 kwh, 0 gal. gasoline Where does the electricity come from? NV Energy, 0.66 kg of CO2 per kwh 3,773kg of CO2 per year

Prius Mpg = 51 14,600 /51 = 286 gal 8.8 kg CO2 / gallon of gas 2,516 kg CO2 per year

ELECTRIC = GREEN, RIGHT?

4kw system in Reno would yield 6,135 kwh Upfront cost $30,000 With rebates $16,000 Lease cost of $110

COST OF PV?

If that’s correct:Me: 18,000 miles per yearChevy Traverse 19 mpg avg

=947 gallons of gas @ $4/gal = $3,789/yr

Leaf would cost me $947 / year = $2,842 savings/yr

Can’t pull a trailer, though.

$1/ GALLON?

There are fuel-saving vehicles that save enough fuel, and come at a low enough premium, to pay back very quickly But there are lots of vehicles that don’t But that’s not the only reason people buy them

If: price of gasoline goes up, and electricity stays affordable, and Electric cars get better range They might get a lot more attractive
