Also they tell us that electric cars are more environmentally friendly, producing less CO2.
I have to say I find that extremely difficult to believe. Extremely difficult.
First of all you have all the mining of the Lithium, the manufacturing of the batteries and shipping it all over the globe. Not to mention the environmental cost of disposing of all the batteries
But putting all of that to one side, the basic physics of it makes it hard to add up. Every schoolboy knows that conversion of any form of energy to another form is lossy - it's never 100% efficient. It's often only 50% in fact, unless special energy recovery techniques are used.
And since half of our power generation comes from burning fossil fuels, you just have to look at how does digging coal out of the ground, make its way to turning the wheels of an electric car?
It goes something like
Chemical energy
Heat energy(burning the coal)
Potential energy (pressuring steam)
Kinetic energy (moving steam)
Kinetic energy (moving turbine)
Electrical energy (generated from the alternators at the power station)
High voltage electricity ( for long distance transmission)
Lower voltage electricity (at substation)
Chemical energy (in your EV battery)
Potential energy (in the car's motors)
Kinetic energy at the wheels.
Vs
Burn the fuel in the car to drive the wheels.
The latter is massively more inherently efficient. The former wastes lots energy (as heat) at every conversion.
I think EVs are the biggest con going but the whole industry has emperor's New clothes about it and no-one has the bottle to call it out for being a sham.
(Not to mention the fact that the poor sod motorist contributes diddly squat to overall CO2 output anyway. The VAST majority of which comes from heating and industrial use.)
The only solid justification for EVs is inner city air quality.
Converts to
Excellent summary but for a range of reasons EV are here to stay and over time as technology improves the cost of production will come down.
I say you shouldn't subsidize one for the other and how are governments going to replace the tax or excise without taxable solutions.
bit like the free pass given to renewables at present which as its rolled out increases the cost to the consumer not forgetting its reliability.
We haven't even looked at transmission lines and phasing to accommodate batteries.
Look at California and the bushfires each year not because of climate change but the faulty infrastructure required to support renewables something the left is not talking about and as for wind turbines many species of birds in the US for example are on the brink as they erect more noisy turbines that no one wants to live near.
Agriculture , deforestation and transportation combines produces far more greenhouse gas than electricity generation and how you are going to replace fertilizer still is the no brainer in quality of food to lengthen our lives is an interesting debate.
you could on and on , yes the days of mass dirty brown coal will eventually wind down but you need dispatchable reliable affordable replacement.
We missed to boat on nuclear her in oz and where we would be in cancer treatment without it god only knows but better late than never.
Ideally we here in oz given our climate and population distribution we should move to 60 per cent nuclear , 20 per cent fossil and 20 per cent renewable ( including hydro ) IMO for the 22nd century.
Battery storage is just not viable until massive improvements in technology and delivery are achievable.
As for EV I know the vast majority of Australians won't be driving one in 2050 because they cannot afford them and an ever increasing number of Australians have no off street parking.
maybe they should research car implosion and extraction like they had on the Jetsons so when you look at the matchbox version it turns into a normal sized version (LOL).
its basically ideology IMO.
I laugh at the likes of Tim Flannery who back in the late nineties said parts of Sydney would be under water from rising sea levels and rainfall would reduce by 80 per cent if we didn't close down our coal fired power stations by 2010.
Well he got one thing right it is under water today because of the heaviest falls in some parts for 20 years.
I am sick of the likes of AL Gore and his agenda to make him and his mates rich off the back of ideology.
A bloke whose family made their fortune from selling tobacco and sold his media interests to a company that is only on air because of oil.
A complete an utter hypocrite of the worst kind.
At least Megan and Harry only want to make themselves heard through virtue signalling and other relatively harmless endeavours like playing the victim compared to massive divide between rich and poor that climate change " responses " will only increase.
