Towards the end of the BBC TV news report on this, they spoke to a Dutch company who can manage to make the switchgear without using this particular gas, and have been doing so for many years. I expect it costs more and therefore isn't as widely used as the cheaper alternative.

Its funny with all these things going on its the lowly motorist that gets demonised for their cars.
A report here that says a Tesla 3 produces 11 to 15 tons of CO2 in the manufacturing of its batteries and when you add the CO2 produced generating is electricity over its life its more than that produced by a Mac diesel.

Electric cars are good in the cities but thats about it.

Well who do you believe?. In truth I don't believe either of them till I know who funded the research, who it was for and what their brief was. If there is any conclusion I would take from this it would be along the lines of, if electric cars are greener then its not by a huge margin.

Not really an electric cars issue at all, more about high voltage switchgear.
While changes to generation/distribution may be a consequence of CO2 concerns they don't have much to do with electric cars. IIRC we're actually needing less electricity of late because of efficiency of modern electricals.

I believe the Skeptoid one - I have known the site for years and know that they are very thorough with their research.
Also when looking at electric cars the type of generation does need to be looked at when comparing but as more and more renewable electric cars will be more and more the better choice for reducing carbon emissions.

One of the biggest problems when comparing ICE cars to EVs is that quite a bit depends on factors outside of our control - namely how the electricity the latter uses is generated and other factors such as where all the raw materials come from and how the energy to manufacture the car is made. The other issue is that currently there is a finite generation capacity for electricty from each source, so everyone can't be on a 'green' tarriff for the domestic supply.
Additionally, how the car is to be used makes a big difference, and for most people, their car usage changes over the course of a few years, because they move home, jobs, get married/have a family etc, thus what may seem a good choice today is not in the future, and not everyone can afford or wish to keep changing cars (which will always lose them money) when that happens.
I don't think there is one definitive answer to what is better yet - it's still, for me at least, a 'horses for courses' argument, adding in the large difference in the purchase price that mostly means you'll have to do a huge amount of driving to make it back, as for most people, the environmental aspect has to take second place (at least) to the overall cost of ownership over the period they are likely to own it, including the purchase and selling price.

Just purely from an environmental point of view it's been shown that electric cars are better than fossil fueled cars at least here in the UK based on how the electric is generated and more and more renewable/low carbon generation is always being added.

Not if additional factors such as what the turbines etc are produced using (raw materials and energy) and that they don't last anywhere near as long as purported, needing a LOT of maintenance (I bet all those maintaining them don't drive there using EVs either). As I said, its also HOW you use them. It's not just as simple as you state, as those saying how green EVs are conveniently forget to add in all those factors.
What would make a huge difference is if as many homes and business/public buildings had PV panels (especially new ones - particularly the latter categories), meaning that charging vehicles would be much less expensive and reducing the price of panels, encouraging further R&D. As it stands, very few of them do. Solar enery is free and requires far less maintenance that turbines, and can be of benefit to everyone, including financially. Turbines still have to be heavily subsidised by the taxpayer.

Have you allowed for the costs for building the fuel refineries, oil rigs, transportation of the fuel round the country in your calculations for fossil fueled cars?
Saying that the people that maintain don't use electric vehicles is just a nonsense argument - they have to use the vehicles that gives them access to where the turbines are located - at the moment as you know electric vehicles can't replace all forms of transport.
Solar can (and should) be used but not as useful as wind turbines particular in the UKs climate.
Turbines don't need to be subsidised to be installed - the government chooses to encourage businesses to install them and quicken their uptake.

That first point makes my point from earlier - no-one on either side of the debate has ever allowed for ALL these ancilliary factors, hence why it is so difficult to analyse and certainly not if you are comparing someone who runs a car for 3k miles a year to 20k, for example.
My maintenance comment was about wind turbines, NOT EVs - doing so in remote areas (especially offshore) is NOT cheap, nor is their installation. And whilst the UK does get a lot of wind (though mainly consistently only in the North - meaning it is not evenly distributed throughout the UK), it is often very variable, meaning some days we get none, other days the wind is too strong and the turbines have to be switched off for safety reasons. Wind turbines are also a blot of the (otherwise very picturesque) landscape.
Even though the UK gets far less solar enegery from the sun than nearer the equator, with advances in the tech, we can still get a reasonable amount from PV panels all year round, even when it is a dull day. Obviously we can't get any at night, but then we have similar issue with wind turbines when the wind is too weak or strong.
I've also read many articles from reputable sources saying that large scale wind turbine tech is still not profitable unless governments heavily subsidise them. Solar is relatively cheap, unobtrusive and can be retrofitted to most buildings, directly benefitting their owners/users and without the need for installing huge amounts of infrastructure at a cost of £Bns in one go. Now we find they use chemicals in their machinery that are tens of thousands worse for global warming than CO2 and which DO leak.
If taxes (lowered on equipment and work), planning and the Building Regs were changed to force new build and to encourage existing building owners to put up PVs, think how quickly our energy dependencyon (foreign) fossil fuels etc could be reduced. it would also be a shot in the arm to the UK construction industry and we could become a bigger player in the tech (especially R&D) generally.
The same goes for increasing the take up (where possible and practical) of cavity wall and roof insulation on older homes/buildings, which, compared to our Northern European neighbours, is woeful and contributed a huge amount to the demand for fossil fuel-based heating.

I've thought this for a long time, decentralising our power generation (and making it less susceptible to attack should the worst happen), also incorporating geothermal heating in new estates, but will it happen? Usually, someone somewhere has to make a unreasonable profit. I don't have any faith in governments in this country to be forward thinking enough to make big decisions and take advantage of the potential that we have on our doorstep. I've mentioned tidal power before (some of the strongest tides in the world here, and they are predictable), and some projects are now getting off the ground in Scotland.

There is very little scope at the moment for reducing the UK's carbon emissions.
Look at the figures as of now - 24.00 hrs today, from gridwatch uk in % age of total generation capacity.and source of the power.
Nuclear 27.5%
CCGT - gas fired 44.4% - (lot's of CO2 emitted)
Wind 5.%
Where are all these renewables?

Where are all these renewables?
The numbers quoted come to 80%. What made up the other 20%?
Right now at 09:00 BST solar/biomass/wind/hydro are around 16% with another 12% (probably mostly nuclear and wind) coming from French Dutch and Belgian interconnects.
Obviously the CCGT figure should be being reduced over time but it's much more CO2 efficient than the oce dominant coal so UK electric's contribution to worldwide emissions are on an improving curve.
|
"so UK electric's contribution to worldwide emissions are on an improving curve"
In a practical sense the UK's contributions to worldwide emissions are negligible at 1.5 to 2% .

What's your point? Add up all the EU countries and it's a decent chuck of emissions - and they need to come down...thankfully I think we are reaching a peak and serious investment is being put into bringing them down.

Electric cars are good in the cities but that's about it.
We visited a very small town in the wilds of Northumberland last spring, and found a car park able to take about a dozen cars, and intended for walkers to a local 'beauty spot'. Somehow this car park had acquired a charging point. I am still wondering how it was at the top of someone's priority list.

Someone thinking ahead...it's the kind of thing that will be required to ensure electric cars will be come the default choice for people over time. Also I'm not sure why you think it was a priority? Was something else required at the car park?

<< Also I'm not sure why you think it was a priority? Was something else required at the car park? >>
Didn't look like it, unless someone had marked out a few parking slots.

Car buyers are often ruled by the heart rather than the head. It's sometimes a case of 'I want one of those'. Look at all the big SUVs and high performance cars on our roads. People don't buy those because they need them, they buy them because they want them. The same goes for electric cars, or rather it soon will do.
I never thought to myself 'I want a Nissan Leaf' or 'I want a Renault Zoe' but I definitely do want a Tesla Model 3. Sadly I can't afford one, nor any of it's petrol or diesel rivals, not brand new anyway!

As above, people buy the car they want, not necessarily what they need.
My feeling is the "tipping point" on range is about 350 miles. Some are pretty much there. Once this is about the norm and the prices come down 20% or so to equal with ICE models then I think they'll go mainstream pretty quickly.
All the major manufacturers have a deluge of models coming in the next few years so there will be plenty of choice.

Someone spotted a grant opportunity and had it fitted for free - is my guess.
