Silent running electric-car
I traded in our trusty Mercedez SUV for a Chevy Volt last August. Since then, our fuel costs have dropped 95% and our CO2 output is 82% less. And we get rock star parking. ------- Download and read the slide notes for additional information and calculations. For example: In August 2012, I traded in the Mercedez and leased a 2013 chevy volt. The smartest vehicle on the road today Volt is known as a plugin hybrid Large battery + electric motor. 35 mile range on just the battery Small gas engine that kicks in only when the battery is depleted. To calculate the cost/day of fuel to drive our Mercedez ML 430 to work Based on 20 mile commute each way: 40 miles daily. 40/15 mpg = 2.6 gallons of gas per day 2.6 * $3.95 = $10.17 / day http://www.slate.com/articles/news_and_politics/explainer/2006/11/how_gasoline_becomes_co2.html The carbon from the gasoline mixes with oxygen from the air. Gasoline consists mostly of hydrocarbons—chains of carbon encircled by atoms of hydrogen. When the hydrocarbons burn, they break apart and recombine with the air. This reaction produces heat, as well as two chemical byproducts: water and carbon dioxide. My commute is 14 miles each way, so 28 miles / day. The Volt’s electric range is 35 miles, so I get by on just electricity If I need to drive further during the day, I charge up at the grocery store around the corner Discount of 2.5 cents / KWh given by LADWP Time of Use Metering is an additional discount, so I only charge up after 8pm at night http://www.nytimes.com/2012/04/15/automobiles/how-green-are-electric-cars-depends-on-where-you-plug-in.html?pagewanted=all&_r=0 http://carma.org/company/detail/70989 (CO2 emissions by power plant locally) http://www.epa.gov/cleanenergy/energy-and-you/how-clean.html (look up your electricity by zip code) 659 lbs CO2 / MWh .659 lbs CO2 / KWh 400 KWh / month = 263 lbs If I purchase green power from LADWP or install solar panels on my house, I can drop this to 0 lbs of CO2 / month Then the question of CO2 is just about the embodied cost of the materials in the car, and their eventual disposal Global land-air temperature averages http://www.nasa.gov/pdf/719139main_2012_GISTEMP_summary.pdf 400ppm is higher than it’s been for at least 800,000 years http://www.guardian.co.uk/environment/2013/may/14/record-400ppm-co2-carbon-emissions 350ppm is regarded as the safe limit before irreparable harm is done Energy efficient. Electric vehicles convert about 59–62% of the electrical energy from the grid to power at the wheels—conventional gasoline vehicles only convert about 17–21% of the energy stored in gasoline to power at the wheels.* http://www.fueleconomy.gov/feg/evtech.shtml

- My wife and I inherited this from her family. I loved it. Great when we lived in Colorado: 4 wheel drive, solidly built, had 180k miles on when we traded it in. It had a good life and served us well.

- Overall plug-in hybrids and electrics are much cleaner
- In LA we see plenty of this. When we’re stuck in traffic, when we wake up in the morning and look out over the city we see smog, and traffic pollution is a major cause of global warming which is a contributing factor in wildfires, droughts and other extreme weather.

- But it’s not all doom and gloom. We can be sustainable and still have some fun
- Torque is immediateCompletely silent… you just hear some wind and the tires on the roadMisconception that electrics are slow
- Ralph’s around the cornerApps that look at your location, tell you the nearest charger, and if it’s in use right now.

- Imagine going on a trip, and coming back to a full tank of gas.
- And whole foods
- A $40,000 car ends up costing $32,500
- Assuming cost of .072 per kWhAnd average miles / kWh of 4.58And 15 MPG at $3.95/gal15/3.95 = 3.79
- The Department of Energy gave me a 220-volt fast chargerAnd LADWP paid for electricians to install it.In exchange, they get data about my charging habits
- Last month I spend less than $12 on electricity. And didn’t buy 28 gallons of gas.
- More and more vehicles are available now, across a wide range of prices. And within 2 years, used cars will be available (when today’s cars come off lease)
- Most of the energy needed to drive a car is used during accelerationWhen you hit the brakes you covert that momentum in to friction/heat and waste that energyHybrids recover this energy through regenerative brakes. Some of that energy is then used to accelerate the car again
- I take issue with cars like this. It’s a “lite hybrid” which means it has a small battery and a hybrid badge. But the MPG sucks, and it put out a lot of CO2… about the same as a normal gas car.
- Fisker, sadly now out of business.Beiber drives a chrome one around LA.
- I found a special lease, and traded in the ML. My lease price is $167/month. Which is less than what I spent at Renovo each month on lunch

- HOW MANY PEOPLE ARE PLANNING TO BUY A DIFFERNET CAR IN THE NEXT 2 YEARS?
- Battery technology is changing rapidly. And like laptops, electric cars will innovate quickly which reduces value of older electric cars. Batteries hold less charge with age as well.The smart thing to do is lease, so you can get a new car / new battery every few years.
