    Both mine are on the ground floor, on quarry tiles, so a flood, while inconvenient, would not be major problem. And I don't babysit them even in the daytime - we have mains-powered smoke and heat alarms so we'd be as alerted to any fire problem as quickly overnight as at any other time (probably quicker than if we were in the garden: no-one could sleep through those things!)

    I do have a delayed start gizmo on white goods and I might start to use it.

    With the tracker, if seems, for London, that wind speed is the main determiner, not so much demand levels or time of day. Here the wind picks up on Friday (pictured in green). Other areas of the country might well be more affected by other factors. 

    Red areas of the graph are high intensity, amber medium and green is low.

    Ah that's interesting - I'd noticed that but not worked out why. Glad you're on the case, @Fire!

    I can't say that's it definitively, but watching over the week, there does seem to be a pattern (for London).

    I would say that with the organising partners involved, the data and efficacy should be pretty kosher  (National Grid, Oxford and WWF), though lord knows Harvard does kick out some dodgy stuff. It's worth watching.

    I was looking at the Drax energy stats site, trying to map on the Oxford data. I'm not sure it's useful - all very complicated, with so many variables. It seems that changing wind speeds (at least nationally) are not reflected in changing energy prices, even though wind speeds seem to make a huge difference to level of carbon use intensity.

    Perhaps here wind supply does track national emissions levels. When wind falls national emissions rise and when wind rises emissions tend to fall. (?)

    This is gas supply against emissions over the past year, and they do seem to track each other pretty well.

    UK national average was 6.2 in 2020 (just checked the BEIS latest figures and updated)

    I haven't done one of those for ages, but you've prompted me to do this one: https://www.ecotricity.co.uk/carbon-footprint-calculator (I don't know how the different ones compare). 2.84 tonnes apparently. I imagine most of that is having a gas boiler and eating meat.

    it says I'm over 11 tons. but some of the questions are a bit odd. You can click either detatched house, or bungalow , but not both.
    There was no option to say 0% food waste, so I had to say 10% .
    I've not flown in years,but said when i fly I fly economy. A bit confusing there too as it was historical, and not now.
    It asks how I heat my home, but now to what temperature, or how often. 
    I've had to say i drive 14 hours a week, but only to visit Husband, usually it's less than 1 hour. 
    Not the best thought out survey, so I can't see how it can be accurate.
