Electric Cars - An Extraordinarlily Bad Idea

Forbes Louis Woodhill

President Obama has announced a goal of having one million electric cars on American roads by 2015.  The administration has allocated $2.4 billion in “stimulus” money to subsidize production of them, along with the batteries and other components that they use.
Unfortunately, electric cars are about to do a barrier crash into economic reality, and all the airbags in the world won’t be able to save them.  The taxpayers’ $2.4 billion is destined to join Obama’s $535 million investment in solar-panel manufacturer Solyndra at the bottom of the crony-capitalism “stimulus” rat hole.
The Nissan Leaf is the first mass-produced “battery electric vehicle” (BEV).  It uses state-of-the-art lithium batteries.  Despite this, the Leaf makes no sense at all.  It costs much more than($28,550 vs. $17,250) a comparable Nissan Versa, but it is much less capable.  The Leaf accelerates more slowly than a Versa and has only about 25% of the range.
At $0.11/KWH for electricity and $4.00/gallon for gasoline, you would have to drive the Leaf 164,000 miles to recover its additional purchase cost.  Counting interest, the miles to payback is 197,000 miles.  Because it is almost impossible to drive a Leaf more than 60 miles a day, the payback with interest would take more than nine years.
However, cost is not the biggest problem with BEVs.
On Wednesday, Jan. 26 a major snowstorm hit Washington D.C.  Ten-mile homeward commutes took four hours.  If there had been a million electric cars on American roads at the time, every single one of them in the DC area would have ended up stranded on the side of the road, dead.  And, before they ran out of power, their drivers would have been forced to turn off the heat and the headlights in a desperate effort to eek out a few more miles of range.
This illustrates the biggest drawback of BEVs, which is not range, but refueling time.  A few minutes spent at a gas station will give a conventional car 300 to 400 miles of range.  In contrast, it takes 20 hours to completely recharge a Nissan Leaf from 110V house current.  An extra-cost 240V charger shortens this time to 8 hours.  There are expensive 480V chargers that can cut this time to 4 hours, but Nissan cautions that using them very often will shorten the life of the car’s batteries.
No doubt some conventional cars ran out of gas while trapped in the massive traffic jams that occurred in and around the nation’s capital the night of January 26.  However, a two-gallon can of gasoline can get a stalled conventional car moving again in a few minutes.  In contrast, every dead BEV would have had to be loaded on flatbed tow truck and taken somewhere for many hours of recharging before it could be driven again.
The short and highly variable range of a BEV, coupled with its very long recharging time, creates the phenomenon of “range anxiety”.  The car takes over your life.  You are forced to plan every trip carefully, and to forgo impromptu errands in order to conserve precious electrons.  And, when you are driving your BEV, you are constantly studying the readouts worrying about whether you are going to make it through the day.
Reviews of the Leaf are filled with accounts of drivers turning off the A/C in the summer and the heat in the winter.  Some drivers even decided that they couldn’t risk charging their cell phones, using the radio, or turning on the windshield wipers.
Between subsidies and fuel economy mandates, the federal government may be able to force auto companies to manufacture 1,000,000 electric cars by 2015.  However, it won’t be able to force people to buy them.  As the economics and operating characteristics of BEVs become more widely understood, interest in BEVs will wane.
What is truly tragic about all of this is that there is an alternative for powering cars that makes far more sense than electricity.  It is compressed natural gas (CNG).
Thanks to new “fracking” technology, natural gas is cheap and abundant in the U.S.  On an energy content basis, wholesale natural gas is almost 80% cheaper than wholesale gasoline right now.  And, it is possible to build CNG vehicles that do not provoke “range anxiety.”
The Honda Civic GX, which is a vehicle that was adapted for CNG rather than designed from the ground up to use it, will be available in all 50 states for the 2012 model year.  The Civic GX has a range of 200 to 250 miles, and takes only a little longer to refuel than a gasoline-powered car.
It would be possible to design a CNG car that has a much longer range than a Civic GX, and that could also burn gasoline when CNG was not available.  Such a vehicle would be much cheaper to build than a Chevy Volt, and it would have better performance characteristics.
2015 Review US News & World Report:
The 2015 Nissan Leaf ranks 22 out of 42 Affordable Small Cars. This ranking is based on our analysis of published reviews and test drives of the Nissan Leaf, as well as reliability and safety data..
The Leaf can travel 84 miles on a fully charged battery, and some critics note that the Leaf’s driving range may limit its appeal to some shoppers.
The 2015 Nissan Leaf possesses everything necessary to placate environmentalists, technophiles and any forward-thinking consumers looking to cut back on high fuel bills." 
If you have an unpredictable driving schedule, travel more than 100 miles per day or live in a residence without 220-volt power support, better options are the Chevrolet Volt, Toyota Prius Plug-in or Ford C-Max Energi. These plug-in hybrids can travel hundreds of miles thanks to their onboard gasoline engines."
