Another Elon Musk Bet: Half of All Cars Built In 2032 Will Be Electric
New submitter cartechboy writes "Ears perked up when Elon Musk made another bold statement he'd be 'willing to bet on.' This time he says that in 20 years, half of all new cars sold would be plug-in electric cars. Believe him? The math looks a little fuzzy, and one research analyst is willing to take Musk up on the bet. 'It expects the U.S. plug-in market to grow at a 32-percent average rate from now through 2020. That takes sales to roughly 200,000 units in 2020. Even if that rate continued for another 12 years, which Hurst considers unlikely, that would only take plug-in cars to roughly one-third of the market in 2032, or about 5 million sales. But Hurst thinks 8 or 10 percent annual growth in plug-in sales is more reasonable, taking the total to 480,000 or 574,000 plug-ins sold in 2032 in the U.S.'"
2008 - The Tesla Roadster is a $110,000 (base price) sports car with a 244 mile range.
2012 - The Tesla Model S is a $57,000 - $77,000 (base price) sedan with 160 - 300 mile range.
2015 (estimated) - Tesla Gen III Sedans are targeting $30,000 base price with comparable Model S ranges.
In addition, Tesla is rolling out a "supercharge" network to support changing away from home in convenient locations in target markets. The Model S has also been promised to include a 5-minute battery quick change option. Once that is available at (for instance) gas stations, it'll take as much time to refill your electric as it does to refill your gas car, except it'll cost a whole lot less.
This guy is actually delivering functioning, functional electric cars and building the infrastructure to support them. I wouldn't bet against him; everyone who's done that so far has been proven wrong repeatedly.

The amount of electricity required to travel a certain distance with an EV is roughly the same as the amount of electricity used to refine the gas for a regular vehicle that travels the same distance. According to DOE:

Developments in Lithium-Air batteries are rapidly making them viable, and are conservatively estimated to give ten times the power/weight of Li-Ion.
There's also been a number of advances in high-surface-area electrodes that dramatically increase charge and discharge rates. Some of these have already made it to market, such as the MIT spinoff A123 Systems - which coincidentally enough has developed a Lithium Iron electrolyte that handles extreme temperatures very well..
There's a great deal of industrial interest in improving battery technology, and claiming that there's been no breakthroughs in years is simply ignorant, I'm afraid. If you're paying attention, the future of batteries looks pretty rosy.
Why would anyone engrave "Elbereth"?
I worked with fuel cells for about 7 years, and I'm fairly certain they will never be used in cars on any appreciable scale. They were used as an excuse by the auto industry for a while. ("Don't make us do battery cars. Wait for fuel cells!") Now that battery cars are about to become economical, the excuse is no longer needed, so automotive fuel cell programmes will be scrapped. (There are applications where fuel cells do make sense, but cars is not one of them.)
The main arguments agianst fuel cells are:
* Efficiency. Making hydrogen from electricity on an economcial scale has an efficiency of about 50 %. Charging a battery is better than 90 %. Converting hydrogen back to electricity in a fuel cell is again about 50 % efficiency (so 25 % round trip). Discharging a battery is again better than 90 % (so 80 % round trip). * Complexity. A fuel cell needs a supply of moist air to function. This requires a compressior, a humidifier, a water tank, lots of pipes, etc. All of this costs money, adds weight, and introduces potential problems.
* Cost. Fuel cells require platinum catalysts that are expensive.
* Reliability. Fuel cells just aren't as reliable as batteries.
* Lifespan. Again, batteries are better than fuel cells in automotive applications, and since they are also cheaper, they have a much better price/lifespan ratio.
Modern batteries can actually re-charge quite quickly if you have a powerful enough charger. (A car draws much more power than a house, so residential chargers cannot be very powerful.)
I imagine in the future there will be robots at gas stations that switch batteries in your car faster than you could refill a gas tank.
This is simply not true. The DOE and other groups have studied this over and over again. There is no problem generating enough power to switch over almost all of the US's vehicles to electricity, except a small shortfall in the pacific northwest** if everything was switched. The issue is that power plants spend most of their time sitting idle (in order to be able to meet peak demand), while EVs predominantly charge in off-peak hours. The net result is that EVs increase power plant utilization percentages and are thus a huge boon to grid operators (who unsurprisingly are big supporters of electric vehicles), as they get to sell more power without having to build new plants, and the power that they're selling is a nice even, steady draw.
There is one weakness in the link, but it has nothing to do with generation, or even bulk distribution. It's the final leg of the journey, neighborhood distribution. Several studies have shown that once neighrboods hit 10-20% penetration or so (which is still a long time from now!), you can start having problems with too much load on the local circuits. But this is nothing extraordinary; local circuits are upgraded all the time as neighborhoods grow and power usages change.
** - The pacific northwest, due to its heavy use of hydropower, doesn't have as much idle capacity sitting around at night as other regions. Hydropower doesn't care whether you use it during the night or the day; it's generally energy-per-year-limited, not peak-power-limited.

The one true statement in this paragraph, but not for the reason you think.
Remember what cell phones looked like 20 years ago? Remember that giant brick of a battery? Compare that to the battery on your smartphone today. Now look at what your smartphone is wasting power on beyond just maintaining a cell signal.
It's a common but utterly false myth that batteries haven't advanced much. They've been advancing dramatically and show no signs of stopping. Now, increasing power *consumption* on electronics tends to waste a lot of this, but as for storage, it's had a pretty consistent 8% energy density by mass gain per year. Power density has risen even faster.
Most automotive-style li-ions are rated for much more extreme temperature curves than lead-acid. I've seen some rated for as low as -50C, although -30C is more common. Ever tried to start a lead-acid vehicle in -50C weather? Yeah, that's what a block heater is for. And guess what? The block heater concept works with EVs, too. And yes, the same applies on the upper end of the temperature spectrum.
Again, automotive-style li-ions (which are a different chemistry than laptop-style li-ions, they're more akin to the li-ions in power tools) don't do this; they're amazingly durable. Something you don't seem to get is that there's not just one chemistry available in each family. Battery manufacturers have an array of tradeoffs they can make in chemistry selection, chemistry details, DOD (depth of discharge), and so forth. This radically alters the ratios between price, energy density, power density, and lifespan. For most consumer electronics, they're thought of as disposable. Hence price and energy density are typically highly optimized at the expense of power density and lifespan. For vehicles, lifespan is fixed at a target (usually something in the 7-10 years to 20% capacity loss range), power density is fixed at whatever the demand is (high for hybrids, medium for plug-in hybrids, low for pure EVs - basically, the more batteries you have, the less power you need per cell), and then the price/energy density tradeoff is adjusted for the vehicle's particular market niche.
Simply not true. Grid operators are dying to get their hands on used batteries from the EV industry which they could snatch up at bargain-basement prices. As if they care that they're only 80% capacity or less; energy density is practically irrelevant when your batteries sit in a warehouse in a fixed location, and 50-80% of the density of a li-ion is still way more than a lead-acid anyway.

Fascinating link.
Alas, it's carefully overlooking a few key details.
One of which is that the energy of crude oil is in no way related to the electricity required to refine said crude oil.
What they're actually making a guesstimate to is the amount of electricity that could have been generated INSTEAD of making the gasoline.
And they're overestimating that by assuming that the making of electricity is 100% efficient.
Which it's not, in case you were curious.
"I do not agree with what you say, but I will defend to the death your right to say it"
I may be getting old, but I always hear about some catastrophic effect that new technology will have. As CPUs approached 50Mhz, people were telling warnings about if their frequencies got faster, there would be widespread FM interference.
With the public availability of wifi, people made relations to the 2.4Ghz signal being so close to microwave ovens, that the world population would be sterile, we'd all die of cancer within a few years, and other false claims.
Ages ago, it was suggested if the population started (oh my gosh) having their own vehicles, the road infrastructure would fail. There simply wouldn't be room on the roads for all the cars, and if there were, there would simply be no usable area for anything but highways.
And lets not forget about oil shortages. The 1950's, 1960's, 1970's, 1980's, (I think we forget about it in the 1990s), were all going to be the end of the world, because there would be no more oil, or at least not enough to provide for consumer use. I doubt many people here remember WWII war rationing.
As for your assertion that there will be a conflict with electric vehicles and power grids, is irrational. Sure, if everyone bought an electric car today, and plugged them all in at 6pm, it would most likely cripple some areas.
We'll use the Chevy Volt as an example, since it is a newer plugin hybrid that is available to consumers.

For comparison, a 3 ton residential air conditioner draws about 14A@240VAC. A 4 ton draws about 17A @240VAC.
It could be equally claimed that building newer homes in excess of 3000 sq/ft with vaulted ceilings would have crippled the power grid. I may not have received the memo, but it looks like we all still have power for our computers, so I'm guessing the power grid survived. That gives a good impression of what the peak current is. For those who turn on their air conditioner (or heater, depending on location and climate) when they get home, make dinner, watch their big screen TVs, etc, etc, the peak power consumption is higher.
The only real problem would be if everyone bought new plug in electric cars within a *very* short time span. If I were to step outside, and look at my neighbors cars, I would see cars made from the 1970's through maybe 2010. I don't need to look right now, I did last night. I've also noticed similar trends just about everywhere I've been (which is an awful lot of places).
Just like the telephone and cable companies upgraded areas to support faster Internet speeds, the power companies will upgrade areas as needed to support higher demands.
The article makes a 20 year prediction that half of new cars sold will be plug-in electric. That doesn't mean half of homes will have them. That would indicate for half of homes to have them, you'd still be looking more like 50 years in the future. Now think, what was the spot you're sitting in now, 50 years ago? Where I am was a partially wooded rural area, a few miles off a 2-lane highway that was probably farm land of some sort. Now it's a residential neighborhood, surrounded by residential neighborhoods, off of a 6 lane highway, and a 4 lane bypass.
If you think back (or imagine, if you aren't old enough), households have grown, power needs have grown. A typical 1940s
