“Things you know that ain't so”: “electric
cars have a bright future”
No.
The reality is that electric cars are a solution in search of a problem. Electric
cars exist because they have attract large subsidies for their development and
for tax rebates and grants on the sale price. The subsidies paid in the USA,
UK, Germany, Norway and other countries are costing taxpayers billions of
dollars.
Governments
decided to subsidise electric cars because they had been told that they could
lead to a substantial reduction in carbon dioxide emissions, they would reduce
air pollution in cities and they would conserve our dwindling supply of fossil
fuels.
On
the carbon markets, carbon credits can be bought for $7.50 per tonne and
substantial savings can be made at no cost at all simply by switching from coal
to gas-fired generation or by encouraging nuclear power. Emission savings
arising from electric cars cost more than $1000 per tonne.
Most
electric cars are in countries where coal and gas-fired generation provides a
large proportion of the demand. The additional demand of every electric car is
met by increasing the output of these-stations. On average, US power stations
produce about 700 g kg of carbon dioxide per kWh generated. A typical electric
car uses 44 kWh/100 miles producing about 42 kg of CO2 while a typical petrol
driven car uses 3.8 gallons/100 miles and emits 34 kg of carbon dioxide. So, in
the US at least, electric cars increase carbon dioxide emissions. (These
calculations are based on information from the US Environmental Protection
Agency.)
Electric
cars can cause serious problems with electricity supply. In general, most
people will charge them when they get home from work and this is will
substantially increase the household electricity demand over the critical
system peak demand period. In the USA, where each transformer supplies four or
five houses, a couple of electric cars could burn out the distribution
transformer.
Some
people claim that the electric car batteries could be used to support the grid
during peak demand periods. Peak demands occur in the early evening in colder
regions when the battery will be significantly discharged and in the early
afternoon in hotter regions when the car is unlikely to be parked at
home. The cost of battery storage is also high because, for instance, a Nissan
Leaf battery stores 24 kWh, costs $15,000 and lasts for about 1000
charge/discharge cycles. The cost of one cycle is $15 or 62 cents/kWh – three
or four times the cost of power from the US grid.
So
we are left with the fact that their only substantial advantage is the
reduction in emissions. But, as motorcars become cleaner and cleaner their
emissions reduce to harmless water vapour and vegetation enhancing carbon
dioxide. So even that advantage is small and declining.
In
spite of government encouragement and subsidies and the fact that many people
regard the ownership of an electric car is evidence of their “clean and green”
credentials, the uptake of electric cars has been very slow. In the US, it was
predicted that 1 million would be on the road by now: the actual figure is
about 200,000. Most of them are in the warmer south and west because heating
electric cars is a heavy drain on the battery.
It
is highly likely that when the day comes that you can use your cell phone to
call up a driverless shuttle car to provide personal transport it will be
electrically driven because it will be quiet, reliable, convenient and it can
take itself to the nearest recharging station whenever necessary.
So,
as with almost everything involved with the belief that man-made carbon dioxide
causes dangerous global warming, the huge subsidies for electric cars are based
on bad science, even worse economics and place a large extra burden on the
hapless taxpayer and electricity consumer.

Yep, and being electric, they require copper - currently the most conductive material.
Where does that come from? Copper mines. No issues around environmental contamination there, of course...
Electric Cars...What a shocking Story!
“Bryan Leyland to the corner and stand there till I tell you to move (or recant at once)!!!!”
Fads are instantly acceptable, especially if the public can be fooled into thinking they will be a natural part of it. The fad for electric cars, also the hybrids and other such ventures such as our ill directed Humanitarian Aid; the idea that we can take in refugees, illegal immigrants ad lib, are based solely on emotive grounds. A product supplied principally by a Media/ TV coverage designed to have the most impact.
The fact that most of the West has been conned into the great Global Warming scenario shows how emotion can supersede truth, provided its coverage, meets both the Politicians agenda, as of course the scenario prescribed by the United Nations.
As Bryan indicates large subsidies cloud the issues, and no more so, when sanctioned by the authority of a Parliament and by well swayed media opinion. The Clean and Green slogan together with the “pollution” of the airways, the effects of an increase of CO2, the present scary and costly earthquake prone building problems we have now in New Zealand, not to mention the rising sea levels. These are symptoms of a ever growing manifestation of the power produced by that single word FEAR.
The continual use of this word of fear, is bound up with an abundance of confident articles of our future written by bureaucrats sweeping in their generality; which seeing their bias sources, are a most disreputable forms of public utterance and propaganda. Yet they work, simply because they are not challenged enough, and the faint, but obvious factor that our Media is far from being free to publish any contrary viewpoint.
Just how much waste of time and money has been spent on the above we will never know, but as we all know it would be suicidal for any Government to admit that they have been mistaken, let alone wrong!!!!

So, this means I can keep the 350 Holden... good I thought so. One day O offered to take Rod Donald to Blenheim in it. Poor blighter he couldn't cope
Good response Brian.
The carbon footprint, the fluoride in water, the LED push( dangerous 480 nano/m emission),Chemicalised refined food, chem trails, HAARP, Medical drugs and vaccines etc All bad ideas. But what the hell, what can we expect from a pretend democracy. It fosters an education system that turns most of us into zombies who know a lot, but can't understand anything. That includes some of the best educated idiots on the planet. They are a bunch of indoctrinated slaves and make a heap of money to stay that way.
