Here’s my optimistic guess of how things will play out….

Stage 1. EV and PHEV introduction. The next 2-3 years.

Take a look at this page from Plug in America that tracks electric vehicles destined for the US and look at all the companies with plans to introduce electrics in the 2010-2012 time frame. Probably some will not meet their estimated introduction date, but a number should.

Stage 2. Getting to know you. Roughly five years.

A small number of EVs will be sold during the first couple of years to “true believers” and those wanting to make a statement or personally do something to aid the climate problem. Those people will be the real world test cases and their experience will be fed to a larger audience. I’m assuming that the majority of buyers will be satisfied with their EV driving experience.

Fuel prices will already have been climbing as the world economy recovers and desire for personal vehicles grows in the rapidly developing parts of the world. Differential annual “fueling” costs are going to begin to loom large in many people’s minds.

12,000 US average miles per year with a 0.26kWh EV and $0.105kWh power = $327.60.

12,000 US average miles per year with a 30MPG ICE and $5 gasoline = $2,000. Add in oil changes, etc.

Stage 3. Serious market penetration.

After the “first seven” battery prices should have more than halved. Range should be at 150 miles or more. Charge points and battery swap stations should be common in urban areas and along interstate highways.

Purchase price of EVs and ICEs should be roughly equal. Most of us should be able to do 98% of our driving without stopping for a battery swap or quick recharge, just plugging in at night. And the lower “fuel” cost and lower maintenance costs will tip the scale.

Summary. “10-20″ was you number, but I’m thinking it’s possible. Given that there is no intrinsic reason to stick with ICE vehicles, aside from nostalgia, economics will force the switch.

We’ll probably continue to build EV/ICE hybrids for those folks who truly need to drive long distances in more remote areas and for larger vehicles that would require massive battery packs. But I can’t see why we would continue to build pure ICE vehicles.

“THE AVERAGE ANNUAL TRAVEL PER VEHICLE WAS OVER 11,000 MI FOR VEHICLES UNDER 3 YEARS OLD, 9500 FOR VEHICLES 4 AND 5 YEARS OLD, AND ABOUT 4,500 FOR OLDER VEHICLES.”

Add in a skew favoring newer vehicles as many older ones have already gone to their deaths.

PCs didn’t become “office ready” until well into the 1980s. By the mid-1990s you would have been hard pressed to find offices using adding machines and typewriters.

In 2000 consumer digital cameras reached the two meg level which was not a 35mm film replacement. Now we’re at the 12 meg level and film is practically dead.

As far as I can tell almost no company is still making film SLRs. Canon and Nikon list one model but sales may largely be from warehouse stock.

And, no, “the original” is not the champ. There is almost no where that film outdoes digital and plenty of places where digital leaves film in the dust.

Film’s done. Color film will largely disappear in a few years. B&W will hang on a lot longer because it’s pretty low tech to manufacture.

Digital got “good enough” to produce what people wanted to produce. And with the other advantages that digital brings, film got pushed out in well under a decade.

Yes, people sleep at night. Offices and businesses shut down at night. Many industries don’t run 24/7. That frees up capacity that is needed when people are awake.

We can absorb all the EVs we can produce right now and utilities see EVs coming. The grid will be built up where needed to accommodate them.

–

The scarcity of “peak rare earth minerals” (lithium) is about current production levels, not occurrence. Lithium is no more rare than lead or nickel. As demand increases more production will come on line (as it already is).

On top of that, lithium batteries use very little lithium and it is not consumed. It is recyclable.

Nissan is in partnership with a company called eTec which is in the process of installing 12,500 charge points in five states by the time the LEAF comes to market in the US. A few weeks ago they already had 400 installed.

There are a bunch of other companies doing charge point installation as well.

Better Place is testing their battery swap technology in Japan with taxi fleets.

Then add in the drivers who have garages. Many/most already have 110vac outlets installed. And installing a 220vac outlet is not a big deal. It’s just like putting in a dryer outlet – a circuit breaker, a three prong outlet, some wire, and a few bits and pieces.

And don’t forget, we already have the distribution system in place. We don’t have to build fuel depots and tankers or gas stations.

The plug-in Prius conversion uses 0.26 kWh per mile. Average US electricity price $0.105 per kWh. $0.027 per mile.

(The Tesla uses 0.23 kWh per mile.)

A 30 MPG car with $3 gas. $0.10 per mile.

That’s 3.7x.

And gas will not stay at $3 for long.

It took PC’s 20 years to replace mainframes and guess what – the worlds most critical data is STILL run on mainframes.

Digital photography took many times longer than that to replace print – and again, the original is still the champ.

“the grid is ready now” – that’s ridiculous, come on. You’re right we have extra capacity at night, but people are sleeping at night and don’t need the electricity as much.

i’m sure that the battery cost will drop – but there is much more than cost to consider. there is “peak rare earth metals” which power those batteries, among others.

charging/swap may replace gas stations, but it took 50+ years to develop the sophisticated worldwide supply chain and infrastructure to deliver liquid fuels. Replace it in half the time it was built and you’re still talking 25 years.

Drive for 1/4 the cost? forget about it. you’re living in a fantasy land that doesn’t have multinational corporations, lobbyist, large government, or cheap oil. Now that I think about it, maybe you’re living in the future – 25-50 years from now.

I hope that I’ve at least given you pause on your timeline here. Please consider this input and revise your expectations to 20-50 years for mass electrification. I’ve enjoyed the discussion, but have nothing else constructive to add.

IIRC roughly 50% of US driving is done with cars five or less years old. People who drive a lot are buying new cars more frequently than those who drive little. Those people are also spending more than average for fuel. Give them a choice of a car that costs 1/4th as much to fuel and costs less to maintain and that segment of the market may switch quickly.

The grid is ready now. We’ve built our grid to service high peak demand – hot summer afternoons when air conditioning is sucking the power. The difference between maximum peak and low off-peak demand is somewhere around 3:1.
That means that we have lots of surplus capability during off peak hours.

Batteries have reached “good enough”, see “range” below. They will get better. And they will soon get less expensive. A study by Argonne National Lab projected battery cost to drop at least 50% when manufacturing volume hit 100,000 units.

Range. Nissan’s LEAF is offering a 100 mile range with < 10 minute 80% recharge and swappable battery packs (<5 minutes). The majority of US drivers drive less than 40 miles on about 85% of days. Range is already there for the vast majority of drivers.

(Tesla’s S is supposed to offer a 300 mile range, but the overall vehicle cost is going to be high for most people. The numbers might work for someone who drives a lot every day and spends something extra for comfort now.)

Interoperability. I don’t know how that comes into play. Tire shops will still sell and install tires. Body shops will still fix crumpled fenders. Midas will still do brakes, just no mufflers.

Service stations will gradually be replaced by charging/swap stations just like service stations replaced liveries.

You’re right about the Earth never being the same. We’re going to be able to drive just as much for 1/4th the cost while not pumping pollutants into our air and CO2 into our atmosphere.

And am I more optimistic about EVs than about algae? Sure. The EVs are being manufactured right now. Algae, still looking for a proven process at the moment.

You can’t just say that things “may happen” or most likely this or that. I can’t believe that you don’t see your overly optimistic scenario for electric vehicles is exactly the same as the overly optimistic scenario for algae!

Let’s make this transition happen by working together, not against each other. And by educating ourselves on the REAL challenges of paradigm shifts in a global economy that runs at a scale that most can’t appreciate, we can start to have intelligent discussions about what the advantages and disadvantages of the various technologies are.

There is no silver bullet, only “silver buckshot”. We are talking about displacing 300 BILLION gallons of liquid fuel per year, just in the US alone. The BTU content of that fuel is staggering. You don’t just go out and replace it – you spend a lifetime with incremental changes and hope that the whole house of cards doesn’t come crumbling down by risking the whole bet on one technology that has to be able to do it all. There will never be another free ride like we’ve had with petroleum oil, and life on Earth will never be the same when it’s gone.
