The poor uneducated serf population are steered by companies and governments to go 'green' or environmentally friendly.
In the United States of America a Tesla Model 3 started at $35,000 while in Australia the first batch was up for sale at $108,000 before on-road costs and Luxury Car Tax, even though apparently today Tesla has slashed $70,000 from the price, to a more affordable $50,000 landed in Australia.
Is the bleeding the general population for cash really doing the right thing by the environment?
Let's see what some learned people have to say on this subject as documented by abc.net.au on the 7th of March 2018 of the headline:
Fact check: Does a Toyota Corolla emit less than a Tesla?
The claim
Since the summer break, tensions have
been simmering within the Coalition over electric vehicles. Although
Environment Minister Josh Frydenberg has
thrown his support behind electric cars, some on the government benches are yet to be convinced.
In a debate with UNSW's Gail Broadbent, who specialises in electric vehicle research, on
ABC's RN Drive,
Craig Kelly, a Government backbencher who sits on the House of
Representatives Standing Committee on the Environment and Energy,
challenged the notion that electric cars should attract a
taxpayer-funded subsidy to encourage their proliferation.
Mr Kelly
argued it was unfair that someone driving a vehicle in the outer
suburbs of big cities or regional areas should be subsidising people
driving electric cars in the inner city.
He also questioned the environmental benefits of subsidies, referring to the Federal Government's
Green Vehicle Guide, which is run by the Department of Infrastructure, Regional Development and Cities.
He said:
"Look
at the [Green Vehicle Guide] website. A Tesla has a (sic) carbon
dioxide emissions when charged the average of the Australian grid —
that's higher in Victoria, that's higher in Sydney — of close to 200
grams per kilometre travelled. A Toyota Corolla on the same government
website shows only 171 grams of CO2. So, the Toyota Corolla is
significantly less than the Tesla and that doesn't include the
manufacturing emissions."
Does a Toyota Corolla emit significantly less carbon dioxide than a Tesla? RMIT ABC Fact Check investigates.
The verdict
Mr Kelly is cherrypicking.
The
data on the Green Vehicle Guide website shows only the more powerful
Tesla models emitted "close to 200 grams" of carbon dioxide per
kilometre. Most emitted less, some considerably less.
Mr Kelly
referred to "a Tesla" and "a Corolla". However, the website lists 27
different models of Tesla, with emissions varying depending on the
model.
At the time Mr Kelly made his claim (the website has since
been updated), emissions for the various Tesla models ranged from 174 to
212 grams of carbon dioxide per kilometre.
For petrol Corolla models, emissions ranged from 171 to 191 grams of carbon dioxide per kilometre.
Eleven models of Tesla had higher emissions than the
most polluting Corolla (191 grams of CO2 per kilometre), compared with 16 that were less polluting.
All 27 models of Tesla listed at the time of the claim had higher emissions than the
least polluting petrol Corolla (171 grams of CO2 per kilometre).
However,
according to experts, the data for the emissions intensity of the
energy grid was out of date at the time the claim was made.
The
website has been updated since Mr Kelly made his claim with data
reflecting the 2015-16 electricity mix between coal, gas and renewables.
This
resulted in a significant improvement in the reported environmental
performance of the Tesla compared with petrol Corollas, such that five
models of Tesla had higher emissions than the most polluting Corolla
(191 grams of CO2 per kilometre), compared with 22 that were less
polluting.
After the update, 17 models of Tesla had higher
emissions than the least polluting petrol Corolla (171 grams of CO2 per
kilometre), while 10 had lower emissions than even the most
environmentally friendly petrol Corolla.
Mr Kelly does have a point — not all Tesla models are cleaner than Corollas.
However,
it is a stretch to suggest — even using out-of-date 2013-14 data for
the emissions intensity of the electricity grid — that Corollas have
"significantly" lower emissions than Teslas.
And experts said it was misleading to compare high-performance cars with mid-performance ones.
They
pointed out that a fairer comparison for a Corolla was a small electric
car such as a Renault Zoe, which according to the latest data on the
website emits between 121 and 136 grams of carbon dioxide per kilometre —
less than any of the five petrol Corollas.
Context to the claim
Mr
Kelly has been leading a group of Coalition MPs to argue against
subsidies for the industry, warning that providing taxpayer-funded
support could increase emissions.
In January he told The Australian:
"We need to be very careful that any subsidies or concessions we give
to electric cars in Australia will not increase CO2 emissions rather
than decrease them. The risk here is you'll have the rich person in
Balmain buying a Tesla, subsidised by a bloke in Penrith who's driving a
Corolla."
"And the Tesla will have more carbon emissions than the Corolla."
How green is my car?
The
Green Vehicle Guide is designed among other things to help consumers
understand how much carbon dioxide a car generates over its lifetime on a
per-kilometre basis and allows users to compare vehicles across a
number of measures to assess environmental performance.
To get the
data, cars are driven on a set of rollers inside a test laboratory and
follow a set of acceleration and deceleration patterns over a set period
of time dictated by the
European Test Cycle.
The tailpipe emissions are captured and analysed, and the fuel consumption is precisely measured.
For
electric or hybrid vehicles, the consumption of electricity by the
vehicle from the battery is recorded during the same test cycle.
These numbers are then broken up into a range of categories,
including the "fuel life cycle CO2" of a vehicle, which is expressed in
terms of grams of carbon dioxide per kilometre driven.
This is the measure Mr Kelly used in making his claim, as he made clear during his interview.
Up
until recently some of the information on the Green Vehicle Guide
website was out of date, using the 2013-14 mix of coal, gas and
renewables in electricity generation.
The department told Fact
Check the website had been updated with the most recent figures, after
the interview with Mr Kelly took place.
In 2013-14, Australia's
energy grid produced an average of 0.94 kilograms of carbon dioxide per
kilowatt hour. The latest figures show this has fallen to 0.91 kilograms
per kilowatt hour.
Experts contacted by Fact Check said even
updated numbers on the website should be treated with caution, given
that lab-testing using a dynamometer method does not always reflect on
road use, which often results in higher carbon intensity numbers for all
vehicles.
UWA Professor and Director of the Renewable Energy
Vehicle Project Thomas Bräunl told Fact Check: "It is not just since the
Volkswagen scandal that we know these things are not correct. These
numbers are a rough guide but you know all the cars have emissions that
are higher and all have fuel consumption which is higher."
However, in
opinion piece published by Fairfax, Australia's Chief Scientist Alan Finkel used the Green Vehicle Guide to compare emissions of electric cars and petrol cars.
Life cycle emissions
The website's life cycle emissions calculations include an assessment of the carbon dioxide generated by driving.
For conventional internal combustion vehicles, this is produced by burning fossil fuels to power the vehicle.
For
electric vehicles, emissions are embodied in the electricity drawn from
the grid (or potentially from other sources such as rooftop solar) to
charge the vehicle.
This
electricity is produced in a variety of ways, including through coal-fired power, renewables, or a mix.
Victoria,
which relies heavily on brown coal for its electricity, has the most
carbon-intensive power. Tasmania, which relies on hydroelectric power,
has the least.
The calculation also includes the emissions
created by the extraction, refining and transport of fuel from
refineries to a petrol station.
These figures are then divided to calculate average emissions per kilometre driven.
Some
life cycle measures also include emissions from the manufacturing
process. However, this is not included in the Green Vehicle Guide's
calculations "because objective, numerical values for these different
factors do not exist at an individual model level and are never likely
to, given the complexity, uncertainty and high costs associated with
life cycle analysis".
Because Mr Kelly did not identify a
specific model of Tesla or Corolla, Fact Check compared 27 Teslas listed
on the site with five petrol-only Corollas.
The following graph
shows that at the time Mr Kelly made his claim, the data on the website
suggested the small petrol Corolla outperformed the small Tesla models.
Medium
Tesla models had comparable emissions per kilometre, while the largest
Teslas listed on the website had higher life cycle emissions than petrol
Corollas.
Although Mr Kelly appeared to be referring exclusively
to petrol Corollas, Toyota does produce a hybrid version of the vehicle,
which, according to the website, produces 97 grams of carbon dioxide
per kilometre — significantly less than all models of Tesla.
Former government official and Director at Green Energy Markets Tristan Edis led the team who created the Green Vehicle Guide.
"Craig
Kelly is using emissions that are not reflective of the life cycle of a
Tesla, in fact they're already out of date," he said.
Solely
relying on the government's Green Vehicle Guide in January, it would
have been impossible for Mr Kelly to get an accurate comparison between
the vehicles, he said.
"A Tesla Model S has very slightly
lower CO2 than a Corolla Sedan under the (January) Green Vehicle Guide
which uses out-of-date 2015 emissions factors," Mr Edis said.
"If
we then revert to the latest July 2017 emission factors put out by the
Department of Environment then the Tesla inches further ahead."
Fact Check compared all 27 models of Tesla listed on the website to the five petrol Corollas listed.
Applying
the 2013-14 electricity grid emissions data used by the website at the
time Mr Kelly made his claim shows 11 models of Tesla had higher
emissions than the most polluting Corolla (191 grams of CO2 per
kilometre), compared to 16 that were less polluting.
All 27 models of Tesla listed at the time of the claim had higher emissions than the
least polluting petrol Corolla (171 grams of CO2 per kilometre).
As previously noted, the updated data for the emissions intensity of
the electricity grid resulted in a significant improvement in the
reported environmental performance of the Tesla compared with the petrol
Corolla, such that five models of Tesla had higher emissions than the
most polluting Corolla (191 grams of CO2 per kilometre), compared with
22 that were less polluting.
After the update, 17 models of Tesla had higher emissions than the
least
polluting petrol Corolla (171 grams of CO2 per kilometre), while 10 had
lower emissions than even the most environmentally friendly petrol
Corolla.
In his claim, Mr Kelly did mention a Corolla which
had life cycle emissions of 171 grams per kilometre. This matches the
life cycle emissions of a 2015 five seat Hatch Corolla.
What do the experts say?
In his
opinion piece published by Fairfax,
Dr Finkel addressed the question of whether electric vehicles are
outperformed by some petrol vehicles when it comes to emissions,
including the Toyota Corolla, which he described as the best-selling
light vehicle in Australia.
He said using the latest figures for
emissions from electricity generation showed a Tesla Model S has lower
emissions than a Corolla sedan.
"The 2017 Corolla petrol sedan has emissions of 178 grams per kilometre," Dr Finkel wrote.
"The
much larger Tesla Model S 75 RP has lower emissions, at 168 grams per
kilometre, charged on the 2017 national electricity grid (910 kg/MWh
emissions). The comparison to the Corolla is even more favourable for
the similar sized electric Renault Zoe, which emits just 121 grams per
kilometre."
A group of researchers from MIT pointed out in
a recent letter to the Financial Times,
that comparing a high performance vehicle such as a Tesla to a
"sub-compact, low-power petrol one" is a "misleading" comparison.
Mr Edis told Fact Check that Mr Kelly's comparison was similarly flawed.
"If
we want to do an appropriate like-with-like comparison we see Tesla is a
substantially better performer than an equivalent car in size,
performance and features like the BMW 540i," he said.
"A fairer comparison [to a Toyota Corolla] would be the Nissan Leaf, which doesn't appear on the Green Vehicle Guide."
Key to the life cycle emissions from any electric car is the energy mix of the grid supplying the power to charge the vehicle.
When
charged using 100 per cent renewable energy, electric cars produce no
emissions other than those used to create parts and build the car.
When
calculating the emissions intensity of various vehicles, the energy mix
of the grid being used to charge the vehicle is key.
Since 2013-14, Australia's energy mix has changed, with a higher percentage of renewable energy.
Mr Edis said this change would continue because "we're adding several thousand megawatts of additional renewables capacity".
Dr
Finkel said the Corolla, like all petrol cars, would continue to burn
the same amount of fuel in the same way producing the same amount of
emissions for as long as you continue to drive it. On the other hand, an
electric car cuts its carbon footprint over time.
"If, as some
forecasts would have it, the national average grid emissions were to
decline by as much as half by 2040, then today's Renault Zoe in that
year would emit fewer than 61 grams per kilometre," he said.
According to UWA's Professor Bräunl, when using the current energy mix emissions factor as detailed in the
Government's National Greenhouse Accounts Factors from 2017, most Teslas register lower life cycle emissions than a Toyota Corolla.
Victoria is probably the worst case but I wouldn't really blame this
on the electric cars I'd blame this on the energy providers using coal
fired power stations."
Professor Bräunl told Fact Check that
in fossil-fuel reliant states electric cars could be charged during the
evening and use up electricity that otherwise would be wasted.
"You
have a number of power stations that you cannot shut off overnight so
they're going to be running and producing emissions whether you need the
power or not.
"So you can use that energy to charge cars but
you should maybe not attribute the emissions to the cars because the
emissions would be there regardless."
