Today I was knobbing around with performing some back of the envelope calculations on what would happen if all the cars in the USA were instantly converted to electric vehicles [EVs]. I also wondered if this happened, how much more electricity would be needed and how this would affect CO2 emissions. But then, after completing this calculation [summary of my conclusions are at the end of this post], I took a step back again, wondering if this infrastructure were fully realized and developed, how truly sustainable this would be…

It seems today, hardly anyone ever mentions the first step in managing the flow of electrons; energy reduction, conservation or elimination–in two words, behavioral change. It’s all about convenience. And as I brought up in a previous post, when did convenience become a human right?

  • Does one really need more light bulbs or more day lighting?
  • Does one really need the latest clothes dryer or a new piece of rope?

I would hope that those that aspire to go off the grid, first find ways to reduce dependence on electrical items, which can greatly reduce electrical needs, thus making going off grid that much easier. Once one minimizes one’s needs and usage, then a cost-effective system can be designed. Alas, so much of the marketing these days decouples conservation from energy efficiency, making perceptions that energy efficiency is a panacea–it is NOT! Ja, miff’d!

I think part of the problem is, a lot of people from a currency background keep delving into engineering and touting energy independence. Problem is, they don’t understand one of the biggest challenges with deploying an off-grid scenario is seasonal and dependent on geographical predisposition. This is especially HUGE in areas that experience winter, especially in the USA. And so, I would encourage all to look at this idea of electric vehicles, going off grid offerings from a bigger picture perspective, before getting overly excited. The problem we have is green fashionistas who don’t understand the thermodynamics make overly optimistic statements like this about green(er) energy solutions. At best, greener solutions can help ups avoid limits for a little while longer. Not to mention, these green fashionista fail to look at all externalities and the fact that a great deal of renewable energy systems technologies have been and still are predicated on oil–seriously, how do these massive wind turbine generators reach their intended locations? Think about it.

Then there is the matter of what is truly sustainable. Greener solutions are just pushing us from CONG (coal, oil, nuclear, natural gas) to other resources that are also likely to be problems in the longer term. In the matter of all this hype around electric vehicle [EV] batteries, depletion of high quality ores, metals, minerals like lithium, will only leave us with lower quality ores, metals, minerals later on in the future. Batteries that use these rare minerals are likely not very scalable, due to quantity limits and low recycling rates.

Aside: I think using batteries in tandem with renewable energy systems technologies is ‘sacrilegious’. I mean they are toxic, not recyclable, difficult to repurpose. What gives?

And so I say, this is all just a bunch of nuanced, well-intended sustainable development scenarios. When batteries exist that don’t get hammered with time and depth of discharge (DOD), when inverters can simultaneously juggle local production, the grid and a lot more batteries in EVs or other storage devices, then perhaps, real demand relief for the grid can start to happening. It’s going to be a long while for all this, folks, and I’m not expecting it to happen MASSIVELY in my lifetime. Better to PREPARE. to RESPOND. to ADAPT. to what’s coming down the pipe, be it financial or due to the ‘indifference’ of Mother Nature. Fleh.

Oh yeah, about my conclusions…

After looking at the USA energy consumption of gasoline, electricity consumption in 2012-2014, battery longevity, and the cost of switching to all EVs, EVs are not a good way to reduce CO2 emissions give today’s power mix. As a matter of fact, presently, this is pretty darn expensive. But hell, we can invest now or invest HELLA more later, ja?

And so, what I have been saying for over a year now is helping the ‘smoke stack’ industry reduce it’s CO2 emissions is just as good as any wind farm, solar farm or energy efficiency policy/directive. The only way that a massive EV roll-out makes sense is if it is accompanied by a MASSIVE roll-out of renewable energy systems technologies. And based on today’s generation markets, I’d say it’s going to take decades. And so, to me, this all remains to be seen if indeed, this intent to empower citizenry with energy independence by going off the grid will eventually stand as being sustainably developed. And so…

…this all just reaffirms my enquiry on a previous post, A thought about ethanol… if 6% less CO2 will be emitted from EVs, why not just make today’s current auto fleet more fuel efficient to reduce CO2 emissions in the interim future?
