You are in the Garden of England, not the cesspit of ex-industrial Cornwall.

Not sure where this is going. Isn't it more a case that we, as a society, have tried to turn market failures into markets. This is quite simple to do, just charge a lot for something that was cheap before, and that is before government legislation throws a spanner in the works. This Tory government (well the last few years of it) has always stated that it want to keep consumer prices low, then, probably out of ignorance rather than malice, puts in legislation that makes that hard to achieve i.e. now new onshore wind, higher connection fees for PV, stopping grants for building improvements etc. But interesting, the markets has risen to all this and achieved what we thought was impossible a decade ago, and at a relatively low price to the consumer.

Current demand and supply (well capacity potential) is already know to the national grid. It is what they use their predictive models for. The hard part is getting the customers to take advantage of it.

The angle between atoms when they form a molecule. See above where I quoted a few (not going to remember them).

If you already have PIV, then you are a third if the way to MVHR. Does anyone make such a bit of kit that can be added to as renovations progress?

Is that set by the distance between nucleus and electrons? Or does the angle set the frequency?

At the moment. Supply is matched to demand with a statistical model. It is why frequency is not the perfect indicator to over or under demand. I would suspect that in the future, similar models are used to control the grid. So you can charge a store at known times of over capacity, rather that trying to balance 60 million meters to a few million generators.

Of cause you are welcome @tonyshouse. You should be able to explain something I have been pondering. As atoms have different masses, different nuclei to electron orbital distances and at different angles (and I appreciate that is just one model, it can also be described statistically). Do they all absorb the same amount of photon energy? Regardless of what they emit afterwards. So like a big mattress. Thin and fat people can both lay on one, they just sag different amounts. Regarding water vapour, climate scientists make a distinction between the condensing and non condensing parts of the atmosphere. That bit is well understood.

Or buffeting at the local level. This morning I looked at last year's usage (a bit higher than I hoped). But what did striked me is that I use, on average, 1.5 kWh/day, on day rate, with a standard deviation of 0.8 kWh and a maximum of 7.5 kWh/day (no idea what I did that day). So if I was to install 3 kWh of storage, with a 5 kW power delivery, that charged whenever it is cheap, I could probably manage quite nicely. Then just a case of replacing resistance heating with an HP if some sort. May have to run some numbers to see what is cheapest overall. I suspect that a heat pump would give me the best return as 85% of my usage is DHW and space heating.

Beer and wine would be more fun.

That is why I picked Wind as the RE source. A lot of the E7 period is linked in with nuclear. Now there is a problem. We have to get those locals in Cumbria to keep the waste. Everyone knows it is going there long term, they are just holding out for more money.

I did the maths (roughly and quickly as I am on way out). Seeing we have about 22.3 GW installed capacity (wind only) and that produces around 60 TWh/year. So doubling the wind capacity should just about do it. That is quite achievable in the next decade, the last decade we have installed, on average 13.7 GW. But as @Ed Daviessays, with a bit of management, it could be less. We could currently charge about 3.5 million BEVs without any change, 7.5 million by shifting to night charging. That is for the whole grid supply, not just the renewable element.

I work on 0.25 kWh/mile.

If they are keen gardeners, get them a Dobbies Club membership. It costs nothing, and they may go out for the afternoon. Having said that, I did NOT ask a woman out because she suggested that we met at a garden centre.

Except, for the foreseeable future, BEVs are best because of the better efficiency. Noticed that last year, over 50% of our electrical energy came from renewable and nuclear sources. https://news.sky.com/story/more-power-came-from-renewable-energy-than-fossil-fuels-in-uk-in-2019-11898806 Just got to increase that by 60 TWh/year to cover personal transport.

Had a look, only found one in Norway. One of which is in Redruth, which seems an odd place to put one. Though it has been described as the new Shoreditch (Redruth, not a gas pump).

Would they not just pull the main fuse and leave the, what I assume is euphemism, behind.

How about evening classes in a totally unrelated thing. Something to take the mind off the build. I had a good laugh learning British Sign Language. Now I can get approving looks from a few people when I call someone a noisy wanker. Suspect most if use can do that, but I can finger spell it as well.

It is really about risk, the risk of the initial accident, then the risk of s fuel leak. Then the risk of a fire. Then finally the risk of bring burnt. Probably lower than a liquid fuel car. Ethanol burns with a clear flame. I was at Pocono speedway and wondered why they were cooling the driver with buckets of water. An odd sight.

Perceived is a better description.

There is a testing scorecard for modules https://www.pvel.com/pv-scorecard/ Not bothered to download it.

That is the main reason, apart from shading, I would choose them. I would think that not many installers that fitted them are still around, and how long will the service be supported by the manufacturer.

Apart from installation damage, has anyone every had a PV module break? I have seen one solar slate install that got hit by lightening, but that is the only one I know off.

It is the mas of the thing. One of the criticisms of EVs is that they are heavy because of the battery pack. Mirai has a mass of 1850 kg, Tesla 3 is anywhere between 239 and 3 kg lighter. Now I know it is very hard to compare like for like, but at the moment, HFCEV are just heavy bits of kit. Makes me wonder what they are bothering with all the other drawbacks of hydrogen. I also wonder how fast the hydrogen is produced if done on site. Is it really worth pumping in 100 kW to crack water when it could be shot into a BEV. I know these are relatively short term problems, but there must be a reason why car manufactures have gone down the BEV route, especially considering that lithium cell technology is a lot newer than fuel cell technology.

That could be the Renault influence, which is really the French government, who own most of EDF. I wonder who is pushing hardest for EVs to be the only choice, not that it is a bad thing.
