Hope to buy an EV once we get a subsidy. Two items translated from German:
1.85% of all emissions come from only three countries: China, India and USA.
1,400 coal-fired power stations are being built at the moment
147 nuclear reactors “ “ “
Germany’s contribution of CO2 worldwide: 0.0004712%
But Germany wants to save the world by switching everything off, forbids everything, makes everything dearer and wrecks its key industries! (Sounds familiar, ours is 1.2% due to not having nuclear in the mix!)
2.“A study by a physicist and others has shown that the combined CO2 emissions from the manufacture of the battery and the German mix of electricity means an E-car emits 11 to 28% more CO2 compared to a diesel. (Study by Info-Institut Munich)
A Tesla 3 battery costs the climate 11 to 15 tonnes of CO2 due to the energy used for the winning of lithium, cobalt and manganese.
Assuming a life of ten years at 15,000 km/year, that is a cost of 73 to 98 grams/km; authors are Buchal, Hans-Dieter Karl and Hans-Werner Sinn.
Emissions from electricity cost between 156 to 181 grams of CO2/km for the Tesla and therefore much more than a comparable diesel.
The European Policy judges E-cars as Zero-Emission vehicles, which is patently incorrect. A CO2 limit of 59 grams/km has been promulgated for 2030, which corresponds to a consumption of 2.2 litres of diesel or 2.6 litres of petrol and is “ingenieurtechnisch unrealistisch” or unrealistic as seen from a technical engineering viewpoint.” End of quote.
3. My comments gleaned from the internet:
To convert all the vehicles in Germany would need 2.5 Million tonnes of lithium, present yearly worldwide production is 250,000 tonnes.
Drivers in cold countries, like Alaska and Canada report only half the range during cold weather.
Owners have been fined for using fast chargers as those chargers draw as much as three houses and that is not permitted in the contract of the electricity supplier.
As you cannot switch off coal-fired power stations, to charge the vehicle at night may reduce power costs; power stations can already produce electricity cheaper at night plus usage and their profits will increase – benefits passed on – pigs fly!
It has been alleged Japan is trending towards hydrogen fuel cells, where the hydrogen can be produced via electrolysis from surplus electricity. At the moment your solar PV inverter will switch off once the voltage reaches 240VAC + - 7% or 256 Volts at around lunch time, when few people are home to use it and then you also lose your generous 4c/kWh in WA!
Tesla and GM (?) are both losing the US federal subsidy due to producing more than 200,000 cars/year; when are we getting one?
Taxation as a means of achieving prosperity is like a man standing inside a bucket trying to lift himself up.
