Should I treat myself to a Chevy Volt?

Why can't I find a source that supports "largely using coal" that your POV hinges on? In addition to the one I posted yesterday from wiki, here's EIA, EPA, etc., and there are many more (Google). I am not omitting sources that show otherwise, I can't find any! Also note that almost all the power plant construction in the past 20 years has been natural gas, not coal.


Interesting graphs.... thanks for posting....

But I think you proved ERD's point... 49% of electricity is from coal per the charts... true, not as many new plants being built are coal, but it does not change the fact that we are largely getting electricity from coal...
 


Heck, this also proves his point... from the article...

"Worse, the most optimistic estimate is that fewer than 500 cars have been bought by individuals. There's no official data, but it's clear that most EVs have been sold to fleet-buyers."


If only 500 cars are purchased by individuals from a total of over 2 million, it is not a big adoption rate....

And I would be shocked if these "fleet buyers" weren't mostly government agencies.

Suit yourself.

Emissions from EV's and plug-in hybrids in coal power regions are slightly less than ICE cars. Emissions from EV's & plug-ins in all other fuel type power regions, more than half the country, are dramatically lower than ICE cars. Net benefit of EV's vs ICE is already positive and supposedly will increase (coal is already slightly less than half of US power gen, and projections are coal share will continue to decline).

Hybrids emit less than EV's & plugins in coal regions, but EV's & plugins emit less than hybrids in all other fuel regions. So maybe a push overall, but also improving.

And ICE cars are still overwhelmingly the baseline, so hybrids, plugins and EV's are all an improvement even if the entire country was coal powered, instead of less than half...

I was not making a comment on the emission aspect of his post, just the source of the electricity... I do not know enough to say one way or the other which is better... and reading the different articles is similar to the statin post... do you take them or do you not... both sides seem to have valid arguments and statistics to 'prove' their side...
 
Pollution of the world is a "tragedy of the commons" situation. France could adopt EVs on a wide scale given their own greener grid, but unless the rest of the world follows, it's not like polluted air and water will stop at their border.

Yes, my real point is that anything 'green' ought to be implemented where it will do the most good. Anything less is a lost opportunity. And it seems that an EV in France would do the world more good than an EV in some high % coal-fired power area of the US.

For example, solar panels should be installed in areas of electrical demand with the most available sunshine, maybe taking into account the 'dirtiness' of the power they would offset. It takes energy to make a solar panel, put it to best use.

We don't even have to go all in with "green" power. We have enough natural gas to last a century, maybe more, with just supplies from the US and Canada. Given that it probably pollutes 10% as much as conventional coal, if that... seems like "low hanging fruit" for a transition to greener renewables as the technology makes them more feasible and cost-effective.

One of these days I need to study the NG supply issues closer. It is far cleaner than coal, and probably less environmental impact to produce, but I'm wondering why my heating bills aren't coming down (I'm on a NG furnace) if we have so much supply. Ten or 15 years ago, my gas company was looking for people to try out a fuel cell in their home to make electricity from NG and heat the water, and I got on the list (though the payback seemed iffy, I was curious). They pulled that offer when NG prices went up, and I have not seen a return of that approach.

Yes, all I meant was in general, we get 'a lot' of our electricity from coal, more than from any other single source. I wasn't going for precision, just speaking in generalities.

And getting back to NG - I think we should base any environmental claims for EVs/plug-ins on where we are today. If it is different tomorrow, we can re-evaluate. I don't see any sense in pushing a technology ahead of its time. There isn't any huge learning curve for car cos to produce EVs, battery performance is the big red flag. Everything else is relatively minor (not that there won't be kinks to work out, but those can be dealt with later, some of them might even go away with newer battery technology.

The Wall Street Journal:
News Hub: GM pulls plug on Volt, stocks pull back and more.

Chevy Volt. There is a central European language in which the word volt=was. I do think of this thing in the past tense.

I think that car is phenomenal boondoggle foisted off on the unsuspecting AND uninformed environmental idealists.

It was developed at a cost of billions of taxpayer dollars, or using the old bait and switch routine will make the Chevy Spark instead, which likely will be made in Korea assuming Government Motors is forced to build more and more by the benevolent dictatorship of USA

Now contrast that electric disaster with the 2012 Skyactiv Mazda 3, with a 2 litre, 40+ MPG engine of direct fuel injection into the cylinder, with 12:1 compression. Plus a whole bunch more innovations, somewhat too technical to elaborate here. Price range 16K for basic to 25K or so for the GT model.
 
Whoa, even though it's temporary for inventory essentially, that doesn't bode well! "Halo car" indeed...
GM stops building slow-selling Chevy Volts for 5 weeks

Sad to see 1300 workers furloughed for 5 weeks.

But they were so optimistic about 18 months ago (bold mine)...

Letters to the Editor: Electric Cars Make Sense Now, Their Future Is Bright - WSJ.com

October 25, 2010

The early enthusiastic consumer response—more than 120,000 potential Volt customers have already signaled interest in the car, and orders have flowed since the summer—give us confidence that the Volt will succeed on its merits. Electric vehicles will be an important part of the future, here and around the globe, and we are proud to help lead the way.

Signaled interest? Orders have flowed? Heck, that seems a lot worse than my admittedly loose wording of 'largely' coal based! What value is a 'signaled interest', and how do you measure that? Ummm, how many orders does it take for them to 'flow'?

120,000 potential customers! Geez, they sold ~ 7,500 last year, and won't commit to their 10,000 number this year. Maybe they were counting on 6 year old kids looking forward to a new car in 10 years?

And sorry to beat this drum again, but for the Volt to succeed 'on its own merits', they need to drop the subsidy, or we would never know.

I wonder if he's learned to avoid words like 'potential' and 'current' when commenting on the 'Volt', it makes for bad puns. :LOL: Perhaps he now speaks in more 'metered' tones (pun intended, hah, hah, hah).

I actually really like the idea of EVs. I would love having all that low-end torque, low 'fill up' costs, almost silent acceleration, and the elimination of a bunch of complex subsystems in an ICE powered car (that might be an illusion, considering the cooling systems and everything needed for those battery packs). But they just don't seem ready for prime time at this point. Maybe someday.

You mean they are not ready for prime time pricewise, right? If a Volt were $14K you'd buy it, yes?
 
I'd pay 5K for a used one with low miles.

Sure, price is all a part of the package.

At $14K I'd sure take a look. I'm not sure that is the size vehicle I'd be in the market for, so that's a factor. But other than that, it seems like a nice vehicle.

Battery replacement could be an issue for me, since I keep my cars > 10 years. My Volvo S40 is 12 YO, < 70K miles, and running fine, I won't be surprised if I keep it another 4 years.

Looking back at my post, I see my 'prime time' comment was geared more towards EVs than a plug-in hybrid (Extended Range EV as GM names it) like the Volt. The Volt solves the 'range anxiety' issue with the ICE backup. For a pure EV, that would be a major issue for me. Though the vast majority of my trips would be no problem, it absolutely would be a problem every month or so (and at unexpected times, one I think I mentioned earlier, when DD had to take my car to school for a month). That really lowers the value of that vehicle for me.

Price is only one part of the equation.

For me, since I live in a condo, I wouldn't have access to charge the Volt up which automatically rules it out.

But for those who have a garage to charge it up, and who seldomly travel more than EV mode only, the Volt can be a great fit.
 
Someone once told me that to make one Coke can would cost over $1,000. I wonder how much a volt would cost if they produced them in the same volume as Corollas.

Maybe more. Would it increase demand for lithium batteries, driving prices up?

The Coke can is a really poor comparison. You are comparing the mass production of a commodity item to a machinist hand-crafting one in a machine shop. The Volt is not a hand-crafted one-off. And they didn't load the full production cost into the first 1,000 units, they are amortizing it over some number (the 120,000 'potential' customers?).

Here's a homework project for you T-Al. The Volt has a 16 kWh battery. Laptop batteries are mass-produced. So add up the cost of 16 kWh worth of laptop batteries, and see what you get. Even then, you need to consider that laptop batteries often only last a few years, because they suck out a lot of watt-hours from that package. The Volt needs to be much gentler on its batteries to extend their life, so it takes more/larger cells to get that 16 kWh out w/o running them through such a wide charge/discharge range.

I think you'll find the raw batteries alone cost far more than any ICE, and anything with that many batteries will have to have a higher sticker price than ICE until battery prices come down.

The video clip that I posted awhile back said the cost of the batteries in the Leaf was $16,000... I would think the Volt is the same or more...
 
OK... someone posted that the Volt was the same as the Cruze... at first I was skeptical... but looking at the comparison it might be very close...

Interesting that the 5 year cost to own is about the same... Volt is first..
