While Trump wages war on the Woke Environmental Climate Change Hoax China will continue to fill the void. They see the opportunities in investment in renewables and electric vehicles etc. and strategically work toward those ends. Even while they continue using Fossil Fuels, they are rapidly deploying climate solutions in their country and will eventually pull the plug on FF leaving the US, who is investing in the dying industry, high and dry.

Truthfully, haven't we been subsidizing the ICE motor car industry for decades by allowing them to legally externalize costs, and various other taxpayer subsidies? But investment in the future shouldn't be a burden shouldered only by the current generation. Requiring future generations that will potentially benefit to chip in through the use of borrowing/bonds, etc. to contribute their share seems reasonable to me. The glaring flaw in this article (a rather short one) is that McQuillan fails to answer the question, are Tesla's subsidies and externalized costs greater, percentagewise, than the traditional auto industry's?

By Lawrence J. McQuillan • Thursday January 28, 2016 10:53 AM PSTDuring a January 19th panel discussion at the Federal Trade Commission (FTC), Tesla Motors general counsel Todd Maron said: “We make money from one thing: car sales and car sales alone.” In reality, electric vehicle (EV) manufacturer Tesla Motors loses more than $4,000 on every car it sells on a “full-cost” basis (keep in mind that some of Tesla’s costs are heavily subsidized). Tesla’s losses per vehicle are even greater using generally accepted accounting principles. CNBC and Reuters explained: Tesla reports its finances in a different way from the Detroit automakers. Using the generally accepted accounting principles, or GAAP, used by GM or Ford, Tesla’s operating losses per vehicle have steadily widened to $14,758 from $3,794 in the second quarter of 2014.
(...) Instead of making money from car sales, Tesla survives by participating in many government subsidy programs. One lucrative program is California’s zero-emission vehicle (ZEV) credit program. Phil Kerpen explained how the program works: ZEV credits are a mandate dreamed up by the bureaucrats at the California Air Resources Board (CARB), which requires manufacturers to build and dealers to sell an arbitrary number of “zero-emission” vehicles each year. . . . Tesla’s Model S generates four credits per unit sold. This means the company can sell $20,000 in ZEV credits to other manufacturers for each Model S sold—a cost borne by purchasers of other cars.
ZEV credits, pioneered in California, have spread to nine other states. Tesla has collected more than $517 million from competing automakers by selling ZEV credits to those who fail to sell enough zero-emissions cars to meet arbitrary mandates. Charles Lane of the Washington Post said: “Tesla owes its survival to subsidies from taxpayers, who are usually less well-heeled than its plutocratic customers.” The average household income of Tesla owners is $320,000, according to Strategic Visions, a consumer research company. Tesla buyers have also raked in $38 million in California government rebates (they receive a $2,500 rebate for each Tesla bought) and $284 million in federal tax incentives (they receive a $7,500 federal tax credit for each purchased Tesla). The Los Angeles Times calculated that Elon Musk’s three companies, Tesla Motors, SolarCity, and SpaceX, combined have received a staggering $4.9 billion in government support over the past decade. As Kerpen noted: “Every time a Tesla is sold . . . average Americans are on the hook for at least $30,000 in federal and state subsidies” that go to wealthy Tesla owners. This is crony capitalism at its worst. Tesla is in the business of capturing government subsidies, not making cars that people actually buy. At the same FTC panel, Tesla’s Maron said: “It’s imperative are replaced entirely by electric vehicles.” What’s the plan for achieving this? Buried in its 2013 annual report Tesla admitted: “Our growth depends in part on the availability and amounts of government subsidies and economic incentives.”

Until we change the structure of our cities, heck, our lives, all the improvements to individual vehicle efficiency are just window dressing.

I've had a look for the BBC article, but can't find it. Here is an interesting article - in that the $9,000 price tag touted by Nissan for the Leap batteries is actually $18,000 - and that is what they cost to produce, presumably retail would be somewhat more, indicating the BBCs figure of £17,000 is not wildly out bearing in mind we usually pay in pounds what you pay in dollars for consumer goods..

Assuming 10K miles/year would mean it's about $0.33 per mile for batteries.

Also, the Prius has an 8 year 100K mile warranty so any failure in that time frame wouldn't cost the owner anything. There is a prius taxi in Vancouver that has 200K+ miles on it, so cycles don't seem to be an issue with the nickle batteries. The new cost of an array for a Prius is between $2500 and $4,000 - that's at most about 20% of the cost of the vehicle vs. the 74% in your quote above. There are also used arrays available and a lot of people are finding that some that were replaced simply need some corrosion cleaned up to be perfectly serviceable again. Again, cost of technology will come down as more are produced, so I'd expect that cost percentage to drop further.
I know I'm talking about Hybrids instead of pure electrics, but there just isn't that much info on pure electrics (real production ones) available. I know there are a lot of other factors, and that still won't be effective for all people. But for many it is a good solution. I think we need alternatives, and more importantly - I think we need to look at real numbers instead of hyperbole from either side.

I think other alternatives have more to offer - the Japanese had a 50cc ceramic engine a few years back that ran at ridiculous temperatures and rpm, but with gearing could produce a remarkable amount of power from little fuel - but the catalytic converter killed that off. Perhaps it's time to review other/older ideas without the current emissions regulations and see where that can go?

islander wrote: It looks a lot like the study that was done a couple of years ago that tried to prove a Hummer was a better alternative than a Prius for the environment. They included all conceivable carbon costs for the Prius (including manufacture, delivery, repair, energy to operate, and distribution for that energy), and only included the energy to operate for the Hummer - and surprise: the Hummer wins!
As with most things, it depends a lot on the assumptions and where you draw the boundary lines for your evaluation. Yes, Batteries have a higher carbon cost to manufacture, but there are batteries in conventional cars as well (and they need to be replaced more often than the arrays in electric cars due to different technologies and less optimum charging).
Just think about the fueling infrastructure. The power grid exists now for all our homes. Large scale electrical generation is more efficient per unit of work than a lot of smaller internal combustion units. Plus you have to have a whole different set of internal combustion engines running to move fuel around to the distribution stations. This is why you can recharge an electric car for a couple of dollars worth of electricity vs. 60+ dollars in gasoline. So your range is half - that is still far more efficient.
I'm all for looking at the full stream cost of all the solutions, but lets be sure we use the same boundary conditions for each and not use data sets that were selected to push an agenda (on either side).

beamends wrote: This isn't really news to engineers and others who have thought through the whole process, though it's good to have real numbers to back it up. When people talk about 'green' cars they mostly seem to make implied comparisons with 20 or 30 year old car designs. Most of the current generation of small cars look to get around 60 to 70 mpg (diesel). To put that in context, when at my first job in 1979 in a motorcycle shop people bought Honda C90s to get that sort of mpg! It seems to me that car designers are keeping well ahead of 'radical' solutions for now. That's not to say alternatives should not be followed up, the oil is going to run out sometime, but are electric cars really the way to go yet when electricity generation is still far from being renewable?
It looks a lot like the study that was done a couple of years ago that tried to prove a Hummer was a better alternative than a Prius for the environment. They included all conceivable carbon costs for the Prius (including manufacture, delivery, repair, energy to operate, and distribution for that energy), and only included the energy to operate for the Hummer - and surprise: the Hummer wins! As with most things, it depends a lot on the assumptions and where you draw the boundary lines for your evaluation. Yes, Batteries have a higher carbon cost to manufacture, but there are batteries in conventional cars as well (and they need to be replaced more often than the arrays in electric cars due to different technologies and less optimum charging). Just think about the fueling infrastructure. The power grid exists now for all our homes. Large scale electrical generation is more efficient per unit of work than a lot of smaller internal combustion units. Plus you have to have a whole different set of internal combustion engines running to move fuel around to the distribution stations. This is why you can recharge an electric car for a couple of dollars worth of electricity vs. 60+ dollars in gasoline. So your range is half - that is still far more efficient. I'm all for looking at the full stream cost of all the solutions, but lets be sure we use the same boundary conditions for each and not use data sets that were selected to push an agenda (on either side).

When people talk about 'green' cars they mostly seem to make implied comparisons with 20 or 30 year old car designs. Most of the current generation of small cars look to get around 60 to 70 mpg (diesel). To put that in context, when at my first job in 1979 in a motorcycle shop people bought Honda C90s to get that sort of mpg!

I'm waiting for Tesla to make that economical car they promised when they brought out the Roadster (yes, because everyone has $120,000 to spend on a vehicle), and the GM EV1 was around $35,000 before they recalled and destroyed them. I see it as this - find me a car that can: a.) get 300 miles on a single charge, b.) be able to quick charge in 10-15 minutes (if one has to wait, then so be it), c.) be around $20,000. This is what most people want when it comes to a fully-electric vehicle, something that does the same as a gas-powered one.
