Dirty Electricity; The New Oxymoron

A recent Headline from the NYT Sunday paper-How Green are Electric Cars? Depends on Where You Plug In.  suggests that EVs may not be the cleanest form of transportation available and cites a soon to be published Union of Concerned Scientists study.   As an example of the tone- “[W]here generators are powered by burning a high percentage of coal, electric cars may not be even as good as the latest gasoline models — and far short of the thriftiest hybrids.”

(Portland General Electric’s Boardman Coal Fired Plant, now slated to close.)

I re-raise this issue of whether an EV from well to wheel is the greenest transportation alternative because we are now parsing it down region by region, yielding some very interesting variations. See the national graphic found at Carbon In, Carbon Out, Sorting out the Power Grid. For example, Buffalo, NY’s electricity has THE highest per mile equivalency of any region in the country, which means that its kWh generation is the cleanest in terms of carbon emissions and it would take an ICE vehicle having 86 mpg to equal the carbon emission of a Nissan Leaf charging in that region. (Thank you, Niagara Falls) Which zipcode(s) are the worst? Hmm. Think Red States- a swath that cuts from the Dakotas to the midwest to the Southeast.  These are regions heavily reliant on coal generation.  Perhaps most interestingly, Hawaii had one of the worst carbon equivalencies- it would only take a 37 mpg vehicle to equal the carbon emission of a Leaf in Hilo, HI.  Apparently Hawaii needs to accelerate its transition away from non-renewable, imported oil and coal if it is to truly benefit from BEV’s zero emission potential.  And I believe that will happen, as it has adopted several progressive laws incentivizing consumers to buy EVs and landowners to get charging infrastructure in place.  [Note- Denver apparently has a coal problem and is the dirtiest electricity in the country, needing only a 33 mpg vehicle to equal a Leaf.]

But back to the point.  I see that even a 37 mpg ICE is a high efficiency engine compared to the national average, which in 2008 was 25 mpg.  So, even in a region hosting the most dirty electricity out there, in order to beat the emission savings of a Nissan Leaf,  a consumer would still have to buy a small economy car capable of very high mileage.  In most other jurisdictions, few mass marketed vehicles exist (other than a hybrid Prius perhaps 53/46 city and highway mpg) that are capable of attaining the 50 mpg range equivalency.

The transition to renewable energy and away from coal burning plants will continue to raise the mpg equivalencies, region by region. It will also mean that EVs will get cleaner the longer you drive them.  Consider the other benefits.  All the money we spend on electricity, in even the dirtiest jurisdiction, stays in the United States and gets fed into a virtuous loop of economic activity.  Electricity  is domestically produced, comes from diverse and renewable resources and has traditionally been viewed as a quasi-public resource such that it’s pricing structure is extremely stable.  Charging station infrastructure uses an existing electric grid and utilities already have built in excess capacity to meet the load demands of millions of EVs.

We just need consumers (and National newspapers) to start recognizing that clean coal and dirty electricity are both oxymorons.

 

 

 

Thank You for Not Smoking

While I do not smoke, smoking has been a part of my life.   While I could be referring  to my wife’s prior position as Director of Maine’s Center for Tobacco Independence,  I’m really thinking of the thousands of miles through space I’ve been encased in an internal combustion engine (ICE) vehicle, spewing carbon dioxide, carbon monoxide, hydrocarbons and other combusted byproducts.  The closer you look, in fact, the more you see how gasoline is like nicotine.  You need it. You spend money on it, no matter the price.  It gives you a rush.  There’s a supplier on every corner.  And most importantly, you can’t envision your life without it.  Like all addictions, it starts innocently and grows beyond itself until you are no longer in control.

Quitting cigarettes requires stages of awareness– thinking about quitting, seeking the best methods to quit, trying to quit, helping others quit.  Scolding and shaming are not the answer.   Altering one’s lifestyle requires making a commitment to economic and behavioral changes, sometimes painful ones. While nicotine is often referred to as the most addictive drug available, whether over or under the counter, I suspect that we would view gasoline the same way if the pump was empty when we drove up to it.

It is clear to me that smoke free driving is one of the unexpected pleasures of the entire EV driving experience. Though it sounds kind of ridiculous and overstated, when I drive this car, I really do feel somehow cleaner and healthier.  I still own an ICE.  I still use it- occasionally.  But I actually feel guilty when I do, perhaps like a smoker feels exhaling second hand smoke at the person sitting next to them.   I now appreciate the fact that I have a transportation choice and the more I change my behavior, the healthier I feel and the price you and I have to pay is less.   I choose to go smoke free  whenever I can.

You can kick the gasoline habit too.
