  1. More efficient Cars Dr. Ron Lembke

  2. More efficient Cars

  3. Hybrids vs. plug-Ins • Hybrid: Toyota Prius, Honda Insight, Ford Fusion, Chevy Tahoe • Mainly gasoline drivetrain, some use of electric drivetrain • Plug-In Hybrid: Chevy Volt • Electric powertrain, gas backup generator • Electric Car: Nissan Leaf, Tesla Roadster • Electric powertrain, batteries only Volt: $39,145 Tesla: $109,000 Leaf: $35,000

  4. Fuel Cell Larry Burns

  5. Aka Suzuki Swift, Cultus • EPA 55/60 mpg

  6. 2011 EPA Mileage ChampToyota Prius • MRSP $23,810

  7. Camry Hybrid

  8. Green SUVs? Isn’t that an oxymoron?

  9. 2011 MSRP Info from cars.com

  10. Electric cars = $1/gallon? • $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

  11. Electric = GREEN, right? • Suppose 40 miles a day = 14,600 / yr • Volt = 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

  12. Cost of PV? • 4kw system in Reno would yield 6,135 kwh • Upfront cost $30,000 • With rebates $16,000 • Lease cost of $110

  13. $1/ gallon? • If that’s correct: • Me: 18,000 miles per year • Chevy 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.

  14. Summary • 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
