There will soon be 800 million vehicles on the world's roads, this is 1/2000th. That is one in 2000 cars are this type. When you only sell a few, twice as many is 100% growth. This is why we need synthetic and bio synthetic fuels, for those 800 million vehicles.

When everyone drives EVs the price of electricity will skyrocket on taxes alone.

The most useful comparison would be to the penetration rate of conventional hybrids (Honda Insight, Toyota Prius).  The Prius family was first marketed in 1997, but didn't reach 1 million total sales until 2008 (the Insight never got close).  The plug-in market is expanding many times faster.

If this follows a logistic curve, we'll continue to have annual near-doublings for several more years, with the growth rate slacking off after that.  Once the production rate is in the millions per year, there will also be network effects and economies of scale (e.g. sufficient volume to devote new engine families to hybrids and PHEVs) and that will accelerate the trend.

WITH MICRO CAR LIKE TOYOTO I ROAD WE COULD SEE SALES IN MILLIONS ESPECIALLY IN EUROPE, CHINA AND INDIA. IT SHOULD BE A VERY AFFORDABLE AND ECO FRIENDLY CAR. ELECTRICITY FOR EVS COULD COME FROM SOALR AND WIND.

The situation is special in Norway, the yellow segment, NOR. When you buy a BEV, there is no VAT, no CO2 tax, no tax on weight or horsepower. An ordinary VW Golf, these are approx 40% of the price. So an e-Golf (115 hp) costs 252000 NOK while a Golf TDI (105 hp) costs 299000 NOK. Diesel is 13 NOK per litre, equivalent to approx 1,3 NOK/kWh, while power at home costs 0,85 NOK/kWh. Charging at public stations are free for BEVs, no road toll (also free ferries, free parking and you are allow to drive in the bus/taxi lane to avoid ques. These benefits will be evaluated in 2017 or there are 50000 BEV registered. 1413 Tesla were registered in March this year, a record number of registrations for one car in one month since start of statistic in 1992.

Predicting the future is a fickle game - a black art.

It follows the biological model in those systems which relate to organisms and neural paths that incorporate the full gammit of number sequences and as such are chaotic and unpredictable.

To make a meaningful prediction involves trying to filter the most likely relevant future factors as per statistical information net
gathering.

That is like saying 'your guess is as good as mine + B.S. in B.S. out.
Good statistical information is highly dependent on operator insight.
What is relevant from 'just noise'.

From my perspective the political social world interfacing with environmental and technology sciences is a pretty interesting place to try and make a projection.

We can try to make assumptions on past experience or evidence assumptions but that only holds in steady state scenarios so not really applicable.

My own take on this is that we have a good start on the technology but there could be an order of magnitude left across all associated possible grains in as little as 15years.

The politics are particularly fast acting as by decree can impact in much faster time frames say less than 5y.

I would assume that social adaption could work much faster.
That's not to say it will or that resistance to change or the 'dark forces or greed and personal interests the fear or indeed the reality of financial jeopardy can cause stagnation and inaction.

We can see many examples of this behavior in recent history.

I.E.Information or nationalist propaganda cold and hot as well as religious wars based on misinformation'

Climate 'denial' practices including industry interests funding 'denialism and esp 'jobs and economy'.

Scare tactics are effective tools to influence public opinion.

Plainly the various matters mentioned will not resolve by themselves and we should note the efforts of simple bloggers such as ourselves and the site administrators as amongst millions of similarly concerned people in assisting alleviate the worst outcomes as best as we can.

Whats the answer?

Your guess is as good as mine but despite the gloomy prognosis there are signs of lite.

I would hope the more rational 'towards best outcome' from proportional response and action scenario has a chance. It certainly won't hurt.

There is a rather sad end note however and that is the ongoing study and understanding of history of climate and biological extinctions has increasingly boxed predictions in black and white and that' not a good look.

I share with E-P the notion that future market penetration rates of PHEV need not follow current anemic trend, but will accelerate real fast once the MFG's will make dedicated, clean-sheet PHEV designs that will make PHEV's far more attractive than they are today.

First of all, ditch the large and heavy 4-cylinder engine and use small 2-3 cylinder engines of no more than 600-1000 cc displacement. This will give ample of space under the hood to store at least 1/2 of the battery pack, leaving more room in the trunk for luggage. The fuel tank will be downsized from 12-14 gallons to 5-6 gallons, thereby freeing up more space for luggage.

Do away with 5-6-speed transmission by using a pair of motor-generators to simulate a CVT when condition calls for it, like when climbing long slopes with a nearly-depleted battery pack. During typical cruise with the engine running, with significant charge on the battery, the engine can simply be clutched to the differential unit to transfer torque directly to the wheels. The engine can be allowed to provide constant torque when the motor will supplement the engine torque for climbing uphill, while the motor/generator will absorb the engine's torque when going down hill, thereby allowing the engine to operate at the most efficient point in the map all the time.

With charging sockets provided at most workplace parking to be mandated by laws upon increasing popularity of the PHEV's, a PHEV can be charged twice daily, hence will need no more than 15-20 mi of range on battery alone, in order to keep down the battery size and to reduce weight, cost, and increase luggage space.

MFG's can do much better job of promoting PHEV's by providing for optional plug-out, in which the PHEV can serve as backup generator for home or businesses in case of power black out, or for outdoor trips.

The high reliability of PHEV's by virtue of having dual power plants in one vehicle should make it more appealing for a lot of people who don't want to be stranded on the road. The ICE unit may never need tuneup since it will only be used occasionally, perhaps at only 1/3-1/4 of total mileage. So, by the time the engine is ready for a 100k mile tuneup, the vehicle will have traveled 300,000 to 400,000 miles and ready to be retired. The brakes will probably never need servicing, either, and there is no transmission to breakdown or to maintain, nor will there be any conventional starter, generator, water pump, lead-acid battery, and accessory belts to replace, as these are the most trouble-prone items keeping one stranded on the road.

The advantages of PHEV's over ICEV are too numerous...Not too long from now, people will wake up to these advantages of the PHEV's just like they have discovered the advantages of smart phones over the old-style flip cell phones and almost no one will buy flip cell phones anymore, even though smart phones are much more expensive and a lot more bulky to carry. The current trend now is for bigger and more powerful smart phones...The transition toward smart phones took well under a decade...and so will the transition toward PHEV's...perhaps a little longer, but it will happen.

And then there will be FCV's soon to be commercially available that will be able to utilize CO2-free energy. FCV's will have all the conveniences of an ICEV or an HEV, with rapid fillup and long range and never need plug-in, while FCV's are capable of a plug-out to back up the grid. One major advantage of FCV over ICEV is that the fuel tank of a FCV is so strong that will never rupture in an otherwise survivable crash. H2 from RE will someday be much cheaper than petroleum, perhaps will cost less 1/2 per mile travel in comparison to ICEV of today. That will be another incentive for buying a near-future FCV.

So, the near future will look bright for EV's, in both forms of PHEV and FCV, and, with proper marketing, will become MUST-HAVES, just like smart phones of today!

Roger, both Ford and Toyota have dispensed with shifting gears in their hybrid transmissions and have gone to electric CVT.  The major opportunities for recovering trunk space in the near future probably involve the volume beneath the front seats, as well as improved battery energy density.

Ubiquitous charging helps everything, everywhere.

Herman, you're begging the question why plug-in growth today is moving so much faster than hybrid growth in the late 90's.  Tesla alone is moving to volumes of hundreds of thousands, Volkswagen's MQB architecture allows seamless handling of PHEV demand by customers, and Ford at least seems to have a growing stable of products.  Advances in battery chemistry are topics of almost daily posts here at GCC, and those will find their way into vehicles just as fast as they can be proven well enough to write a warranty.

It must have been like this as the internal combustion engine replaced livestock.  Now we're watching it on its way out:  not all at once, but by degrees.

The EV market will grow faster than the hybrid market for two reasons. The first is savings. The potential cost savings for EVs is much larger than for hybrid which still use gasoline. The price of gasoline will do nothing but go up except in the case of a major economy crisis, and in that case the price of gas is the last thing anyone will care about. The second is that despite all of the spin put on the topic in the media and in blogs like this, there are a lot of people who know the reality. We live in an economic empire built around oil, guns, and drugs and the corporations and our leaders who profit most from that system have no intention of changing it. Thus many will choose them simply to do what they can to not be part of the problems created by our facist corporate and political system. Yes, most americans and europeans actually believe in the old colonial facism, but not everyone does, and that's a large enough number so that EVs will grow faster than simple hybrids did.

Massive ground vehicles electrification is a step by step issue:

1. Basically, it started in 1997-1998 with the Prius HEV. Twenty years latter (2017-2018 or so) the world will have about 10,000,000 HEVs. Sales of HEVs have already stared to go down in favor of PHEVs and BEVs.

2. Mass produced PHEVs and BEVs started some 15 years latter (2011-2012 or so). Twenty years latter (by 2011-2033 or so) the world may have 20,000,000+ PHEVs and 40,000,000+ BEVs.

3. Mass produced FCEVs will probably start by 2017-2018 or so. Twenty years latter (by 2037 or so) the world may have 50,000,000+ small, mid-size and large FCEVs

4. It may be 2040 or so before the majority of ground vehicles are electrified. The final mix may be BEVs + EVs with FC range extender.

BEVs were mass produced 10 years before adequate, low cost batteries were available.

By 2020 or so, BEVs with 5-5-5 batteries will start to make sense and sales will pick up.

Meanwhile, PHEVs with smaller ICE or FC range extenders will fill the gap.
