OK, have a little time from my projects, will try to catch up a bit...
See full exchange below, I'll pull out a few excerpts here, but this demonstrates to me that
oneill225 is not really committed to a meaningful exchange. For example:
oneill225: "
I do recall you citing a flawed study that grossly overstated the use of coal to generate electricity. "
See, it is just too simplistic and easy to just say the study is flawed and try to claim a 'win'.
Show me the flaws and how they affect what I'm claiming. Since you didn't do that, it leads to me think that you can't do it, or you would have in order to make a strong point.
Hint: The study certainly is not flawed in the way you state, It actually showed a comparison for each fuel type separately, there was no forced assumption of any amount of coal. There were multiple examples of zero coal. Try again, but this time read and understand what I provided.
Go back to post #739 in this thread:

You tried to make the same 'average grid' argument back in Sept/Oct of 2018. It still doesn't matter, and it still is not what that study shows.
oneill225: " You cannot seriously argue that a car powered by a natural gas plant is less green than a car powered by gasoline (hybrid or ICE). "
I'm not arguing it, I'm showing you the numbers behind it. It depends on a lot of factors, mpg of the ICE/hybrid, and source of the marginal electrical generation to charge the EV. For a 100% NG source, and against their reference hybrid, the EV does show to be better. But not by a lot, and we also don't know what mpg was used for that hybrid. But hybrids have improved a lot in the past few years, EVs still use about the same kWh/mile (there's really not a lot of room for improvement). So I would not be surprised if the best hybrids today are better or as good as an EV on NG.
The important point is, EVs aren't so much better even in that case, that it makes sense to hold them up as "planet savers" or to subsidize them. And, if even a little coal is used to supply that extra demand, it wipes out the EV advantage pretty quickly. And remember, grid operators throttle down their coal plants at night. If a fleet is charging, they will keep the coal plants running a little higher to meet that demand, as long as the marginal coal plant operation is cheaper than the marginal NG plant operation.
oneill225: "I am talking about how the government will tax EVs to replace gas taxes. As it stands, EVs are avoiding those taxes. When that changes, I contend that it will be done in a way that still incentivizes EV sales. Common sense."
It is not 'common sense', it is only your opinion. You might be correct, but there is some evidence to the contrary (posted recently in this thread). I still see no reason why we should subsidize EVs, and since those subsidies are dependent on government, to paraphrase Tina Turner
"What's sense got to do with it, do with it?"
Now, if you want to challenge the above, fine - but can we play by some helpful rules please? Like -
A) Please answer within the context I provided. I see a lot of diversion tactics in this thread. It appears that when the facts become inconvenient, the technique is to change the subject, and try to answer a different question.
B) Provide facts, figures, sources where applicable.
C) No 'appeal to authority' or other logical fallacies - the statements should be able to stand on their own.
D) Just admit when/if you are wrong.
Thanks.-ERD50
oneill225: "I'll pass on the gotcha game, but since this thread is devoted to whether Tesla is a good investment, can you tell us whether you believe Tesla is a stock worth investing in?"
This is why I say you are not being serious. There is nothing about points A-D that has anything to do with a 'gotcha game', just the opposite. Are you saying that facts, figures, context, and good logic have no place in a meaningful discussion? I'm actually starting to believe you
do believe that!
Prove me wrong.
I have no opinion worth discussing on pretty much any individual stock, or even the market in general. I don't have a crystal ball, and I don't have enough understanding of how the other non-car pieces of the puzzle fit into Tesla. I do think there are many obstacles to Tesla in maintaining their stock price, but I don't have enough information, nor the P&L analytical skills to put any money on that. Anyhow, this thread is called "Thoughts on TESLA", not "Thoughts on TSLA", so I think overall discussion of the company and its products, separate from its stock price, is fine. If you disagree, you can report about 98% of this thread to the mods
...Speaking of the above - can you go back and review post #1611? I got lost, what exactly were you trying to say about an ICE owner having trouble finding a gas station? It seems to me you never clarified that. And I think you tried to change the subject from gas stations being hard to find to some general statement about EV sales - IOW, changing the topic instead of addressing the issue. I don't want this post to just go open ended like that, that's a waste of time. So please close that #1611 gas station conversation out and explain yourself before we continue. Thanks.-ERD50
Again, I'd really like to finish that conversation before going on another. It does look to me that you avoid things when they aren't fitting your world view. So what's up on that gas station thing?

Hint: As I've probably mentioned recently, an EV is additional marginal draw on the grid. The grids in the US rarely (most are never) have an excess of RE, so to 'fuel' that EV, a non-RE power plant somewhere on the grid must increase its output. That plant is most likely a gas peaker, but if a fleet of EVs charge each night, it's likely that a grid operator will meet that expected demand with the cheapest fuel available, which may mean keeping a coal plant operating a bit higher overnight than they would w/o that added demand from EVs. Yes, your EV is mainly running on fossil fuel. Average generation on the grid does not matter - it is that extra marginal generation that matters. Any source dealing with average RE on a grid is missing the point.
I do recall you citing a flawed study that grossly overstated the use of coal to generate electricity. Any more recent studies showing hybrids are cleaner? Regarding "marginal" increases in electricity generation, those will be gas plants, as you suggest, not coal plants. So, if we are already using those coal plants, why do you include them in the "marginal" increases? If the "marginal" increase in electricity is met with gas and not coal, then we are talking about a more eco-friendly solution over hybrids and ICE vehicles. You cannot seriously argue that a car powered by a natural gas plant is less green than a car powered by gasoline (hybrid or ICE).
And why should any government encourage their use? If they are so great, they will expand on their own merits.
EVs will no doubt increase over the next few years. After that, who knows? The competition (hybrids, who knows what next?) is not standing still, and maybe more people will understand that EVs are not as green as they have been willing to believe.
Why? It is irrelevant, because they are (I think it has something to do with carbon emissions). By the way, I am not talking about the current incentives, I am talking about how the government will tax EVs to replace gas taxes. As it stands, EVs are avoiding those taxes. When that changes, I contend that it will be done in a way that still incentivizes EV sales. Common sense.
