It depends how you define ‘consistent’. If that means full supply every time you want it for as long as you want it in a domestic environment, maybe that’s not an option anymore?Quote:

People were learning to use electricity at certain times and to ration their use. Showers at certain times.Quote:

I’m sure there are many other examples, not limited to electricity supply but use part of the same wider pattern. It’s not always about shivering in some cold post apocalyptic wasteland of Green austerity or some gammony cliche , but making conscious choices about what’s necessary and what isn’t.
Suspect so, especially with Torness set to decommission in 5 years time. It provides baseline 1.3GW 24/7/365 (except for planned refuelling), which with fag packet maths is 45-50% of Scotlands usage. For comparison you'd need 2.5 Whitelee's to be running 24/7 with the ideal wind conditions to get the same output.Quote:

I guess in conjunction with gravitational energy storage such as the one down the Leith Docks it could fill the gaps for renewables (https://www.engineernewsnetwork.com/...-demonstrator/)
If anyone has any decent reading or viewing on what we're going to do with all these spent lithium-ion batteries from cars and storage plants I'm be keen to see them. Not something I've looked into but keen to learn on it :aok:
Obviously the production process has a carbon footprint and as you say the spent batteries will need to be disposed of. I suppose one reason why they are considered green is they don’t contain toxic metals so won’t pollute after use.Quote:

You can get batteries for your home than will store a full days supply. They can also help you only pay the overnight cost of electricity. Cost about £5k I think but if enough people had them then storage issues could be alleviated.Quote:

This is the future imo. More self generation and less reliance on the grid. It obviously won't work for all or mean we need to completely abandon mass energy generation but micro renewables and battery storage are the way forward.Quote:

Your right that the challenges are much harder for say urban dwellers in a block of flats, and personally that's why we'll always need some form of mass generation through wind farms, nuclear etc. But we need to start shifting the balance. Technology is going to make some of this much easier if its deployed in the correct way (that's a big if though!)Quote:

I think solar panels are a requirement of new builds, for recent sites anyway (2018/19?). Not sure battery storage is standard though.Quote:

Another interesting carbon capture/removal idea that seems to be showing promise.
Obviously we have to be wary of putting too much trust in stuff like this and just carrying on as now but I suppose it could be argue this kind of thing buys us more time and smooth the transition to a lower carbon economy.
They're going to need an awful lot more of these types of things: https://www.power-technology.com/pro...hydro-project/Quote:

I'm not sure if it is part of planning applications now but there really should be a condition of granting permission for new on and offshore windfarms that investment is made into storage solutions like this in order to assist the grid instead of them being paid to shut their turbines down.
Interestingly, the scheme near me is one of the things that Inverness Caley Thistle are banking on assisting with their financial issues that they are encountering at the minute. I'm not sure what sort of stake they have in it though.
I don't think it is an absolute requirement in the sense that it isn't mandatory to have PV panels, however it certainly is one of the most straightforward ways to get a house through the requirements of section 6 of the Scottish Technical Standards.Quote:

Whilst PV panels might provide a solution in terms of local power generation and reducing grid reliance, there's an argument that they aren't actually that green a technology given the high embodied carbon and energy that goes into the manufacturing and disposal of silicon PV systems. Traditionally the high embodied carbon of silicon PV panels was offset by the high grid carbon factor such that you'd be in the positive in terms of carbon reduction after a few years, but given that grid decarbonisation is rapidly reducing the grid carbon factors, it's getting to the point where the embodied carbon of a typical silicon PV panel is more than the carbon is saves by not using grid electricity over the life of the panel.

I found this really interesting (particularly if you’re of the ‘practical solutions to climate issues without the culture war’ ilk). I had given no thought at all to the possibility that MoD land could be a haven for biodiversity, but of course it is. I wonder if there’s ever been surveys of the shooting range areas in the Pentlands? The DMZ between the two Koreas is a much more extreme example of no-go areas that become havens-there are species extinct elsewhere on the peninsula (a rare deer, rumours of Siberian tiger) on that narrow strip of land-A reminder that in the darkest times nature can find wee niches.
I suppose it is obvious when you think about it. The less humans that touch a place the better it becomes for nature and the planetQuote:
