Talk Morgan Forums Community The Malvern Arms Electric Cars

Sadly the JEC Energy specialist disagrees with this "The other option was an Air Source heat pump, again not sure what size would fit until a full survey / design is done probably with a Vaillant Arotherm plus so rads would not change, only issue with this is the max running current cannot be more than 28.1Amps for your single phase supply, which includes Heat pump and bore hole pump." This is with a 100 amp, single phase supply. Maybe second opinion required.

For most of the last 60 years I've used electricity on the assumption that it is "there" at the touch of a switch. Now, from the discussion above, it seems to me that we shall have to get used to using electricity when it is made available to us, not when we want to use it. This is not progress.



Tim, you forgot EV batteries as part of the smoothing process: within the EV community there is an expectation that we will all plug our cars into the charge point when the car isn't in use so power can be drawn from the battery at times of peak demand and then replaced when there is excess power. Fine in theory, but not quite as simple as it seems. It assumes that the majority of homes will have a tethered EV charge point and that the car's battery life will not be shortened by a high number of charge/discharge cycles.

Who is going to pay for all the new hardware and enhanced infrastructure? The consumer, obviously!

I shall not be in a rush to change anything: we have gas and I'll use it as long as I can as the main source of energy. Yes, we have an EV nd an air source heat pump that is an A/C / Heater unit in our bedroom.
Somewhere I have an article from the 1970s that describes how to modify a mid sized petrol generator to run on natural gas. That could be worth trying!

My EV charger pulls 32 Amps, for up to 10 hours at a time. The SSE Engineer said that on each phase, with a 100A fuse, there is a limit to the number of 32A drawing units possible. So perhaps others on your supply loop have some high draw appliances, such as heat pumps and EV chargers, or pool heaters...

It's what you get when you run a nation's energy system in the short-term interests of the (mostly foreign) owners and shareholders rather than the long-term interests of the customers.

The CEGB might not have been the most efficient industry the world has ever seen, but to be fair that wasn't one of its key goals. It was charged with ensuring the whole country had a safe and reliable electricity supply that was engineered to grow to meet its needs, and it did very well indeed at that - including building truly world class nuclear generation in sensible timeframes. Sizewell B being a truly excellent example of how to do it. Then we privatised and let all the expertise drain away.

Is that a fair criticism? ..... large scale energy developments have lead times measured in decades .... up til now the forces driving increased demand have been well understood and planned for ..... even ten years ago, who would have predicted the current snap PR-motivated decisions around the abandonment of gas for heating and rapid phasing out of other fossil fuel use ... and the political rather than economic/technical decision to transfer to electric transport in a very short time span?.

I guess there's lots of crisis planning going on in the generation and transmission industries.

That's why I mentioned Sizewell. Announced in 1980, public enquiry 82 to 85, building started '89, synchronsed to the grid in'95. We had a well-designed energy strategy based on nuclear using the Sizewell design which had proved to be safe and reliable. All abandoned with privatisation as there were no quick profits to be had, so was replaced with the 'dash for gas'.

Even Thatcher was warning about the dangers of global warning back in the '70s. We've known about the issues facing us for decades, the only reason it's become a crisis now is because nobody listened to the scientists when there was plenty of time to sort things out.

As usual, forgive me if I'm slow, but where in the article does it provide any link to an actual Yale university study apart from the initial claim?
I rereaed it and it doesn't refer to anything I can find...

The Yale study was published in Nature. Here's a link

https://www.nature.com/articles/s41467-021-27247-y

I found it by Googling "Yale emissions study", it's the first hit.

There's a lot of good-quality ( ie properly researched, peer-reviewed) stuff on EVs available from the Technical University of Eindhoven.

I suggest you ask the people that published the article Nick i.e. the IET. If you PM your email address I'll send you the email.
