EV Road Trip
NPR’s Mary Louise Kelly is about as good as it gets in the news radio biz, but she conducted a very weird interview the other day with reporter David Ferris of E&E News, an online news site that covers energy and environmental issues. A few observations:
• The purpose of the trip was to “inform ourselves, not just to what it’s like to be in the car, not just to what it’s like to fuel to charge the car but actually how it’s going to affect the whole economy – manufacturing, cities, jobs.” Really? That’s a big expectation for a road-trip.
• Re: eco-friendliness, Ferris says, “We’ve been rigorously calculating the carbon emissions of the charging we’re doing, and that has to do with the power mix in that individual state. If that state uses a lot of coal, the emissions are going to be higher. If it’s a state that uses a lot of hydropower or wind or solar, it’s going to be lower. And in either case, it’s still significantly lower emissions than gas, but it does vary a lot.” Not completely accurate. The cleanliness of electric transportation is a function of what resource is tapped when an incremental load is put on the grid at that particular moment in time, and this fluctuates depending not only on location but the time of day. The average grid-mix in a particular state is a different thing.
• Apparently, in North Dakota there are signs for electric vehicles that say “powered by coal.” Ferris explains, “As it happens, the Lignite Energy Council, which is the advocacy group for North Dakota coal, has embraced electric vehicles as a way to create a market for itself in the future. The writing is on the wall that it’s going to get tougher for coal. And they’ve realized that electric vehicles need to charge and that they could be a good market for coal power.” That’s pathetic, of course; it’s like seeing a cigarette vending machine in a hospital lobby.
• It also would have been worth adding that we could power every car and truck on the road with electricity and the result would be a mere 14% increase in grid capacity; this is due to the dramatic increase in efficiency that comes with batteries and motors vs. internal combustion engines.
• Charging takes perhaps 30 minutes rather than say 5 for a gas tank fill-up, and the suggestion was made that this will mean that drivers become more calm and deliberate, and less impatient as people generally. Sorry, that doesn’t seem probable in the least. It may make drivers stay with gasoline, but I would think that it’s insanely unlikely to change their basic personalities or basic modes of living.
Strange couple of minutes. Wish she had called me.
Craig,
” Wish she had called me” .
Why? You neither own, nor drive an EV ! How could you discuss your real road experience as an owner?
No EV takes only 15 minutes to charge.
Optimum Tesla charge times
Charging Point Max. Power Power Time
Wall Plug (2.3 kW) 230V / 1x10A 2.3 kW 48h45m
1-phase 16A (3.7 kW) 230V / 1x16A 3.7 kW 30h15m
1-phase 32A (7.4 kW) 230V / 1x32A 7.4 kW 15h15m
3-phase 16A (11 kW) 400V / 3x16A 11 kW 10h15m
3-phase 32A (22 kW) 400V / 3x24A 17 kW 7hours
Charging Point Max. Power Time
Supercharger v2 Shared (75 kW DC) 70 min
Supercharger v2 (150 kW DC) 42 min
Tesla have the the fastest charging times of all EV’s.
The point of driving an EV is not how the electricity is generated, but the potential an alternate fuel vehicle offers.
Even if the electricity is generated by coal, so what? That could still be very beneficial for the environment as it would encourage investment and adoption of the latest hi-tech clean coal technology in the generating process.
Any increased economic viability of clean coal technology would encourage coal fired generating plants to modernize and produce the various by-products that help reduce emissions in other essential, but heavily pollutant, industries such as cement, concrete etc.
But most likely, the main attraction of EV adoption is among home owners with large arrays of solar panels who are noticing a drop in the price utilities are paying for feed in tariffs.
The benefits of owning an EV are far beyond just not “saving the planet” by not using gasoline.
“Riding on electrons” for many people is a joy in itself. Very few serious EV buyers are attracted by puritanical sermonizing.
When you abandon seeing energy production through the narrow prism of ‘tribal’ political/ideological warfare, you become liberated and able to appreciate the wondrous opportunities being created by the astonishing advances in environmental technology.
