How is electric green, when most electric comes from a powerstation? It seems your stopping one pollution for another

I think the theory is that generated electricity comes from renewable sources like wind, hydro, etc. None of which can power a car as yet.

It's a sorry indictment of the government's 20-year+ efforts to educate people about the reasons for having more electric vehicles, that we still get a response like this.

Yes - when you think about it a bit, it's just another way of storing power to propel a vehicle, and yes, you could get that power from a coal-fired power station.

But it gives you the freedom to use completely renewable, polution-free energy sources (solar, wind, hydro, wave power) - petrol and diesel do not, in any way that is economically viable.

Surely - it is "greener" to make use of an "already produced" vehicle - considering the fact that lots of resources will have to be used in the production of a new electric vehicle.... ?
Even if the old vehicle is fairly polluting ?

It might, but not here, and I wonder how you would create the wind turbine blades without using oil and causing emissions, or mine transport and process the metal ores.

At the moment a recent think tank study in Germany says a Tesla in Germany and most other countries has higher overall lifetime CO2 emissions than a Mercedes running on diesel or on liquified natural gas.

Renewables currently account for 30% of our electricity and is set to double over the coming decade as we are aiming for net zero emissions by 2050 as recommended by the climate change committee.

This electricity is obviously fed into our national grid just like other forms of energy such as gas and nuclear so clearly it will be used for charging our EV batteries.

For two reasons,,
First, as said much electricity comes from renewables. And yiu can go witha supllier thatbdoes more. All of my electric comes from renewables for example.
Second, electric cars are very efficient,around 90% compared to petrol of about a third that. So, even if running on purely fossil fuels which is not possible in this country, an EV woudl be more efficient than pretty much any fossil fuel car.

Don't forget to include the efficiency of the electricity generation and distribution network.

And a think tank running in AJ Towers says that if you lock yourself in a garage with a Mercedes running on diesel or LNG you'll die whereas in a Tesla you'd merely get bored after you'd played all the games on the big screen,
Screw the CO2 emissions we are all being poisoned by carcinogens produced by lying manufacturers who sponsor "think tanks" to demonstrate the truth of the phrase lies, dammed lies, and statistics

The think tank you are maligning with your invented slurs of corruption is independent, attached to a university, and sponsored by public funds not business.

Let's try to have a sensible discussion without making up tenuous assertions, such as your implication that burning fuel might be several times more efficient in power station generators than in engines.
