I would have thought reasonable clear
Look at the graph on a cellphone, without zooming into it. Then consider mottie's post said there were two lines on the graph; there are actually 4 relevant lines on the graph, but only two are clearly visible on a cell, which is why I told Mottie I couldn't understand his post, indicated what I could see/how I interpreted his words, and waited for the delivered clarification. I now understand the point Mottie was making
up to now the gamble is paying off, but still a gamble.
I dare say it's not an unreasonable strategy to have home storage(one is not prohibited from obtaining either) and a variable price tariff that you can use to fill up the storage when the price point falls.. I don't think it's gambling really, it's betting on horses that you know are going to win.. Likebbuying oat milk in bulk when you see it for 50% off in Aldi..
..but even if one didn't have home storage, it would still be possible to shift use to cheap times, timers on washer/dishwasher, batch cook etc
Everyone has their tolerance of changing schedule to a point where inconvenience is experienced and being offered the choice of operating anywhere in that range all the way up to behaviour another might seem crazy, that's fine by me..
The days of plentiful cheap energy may be gone, and better for the planet if so; getting people to adjust their behaviour to be more sympathetic to the environment they live in is a benefit and one we used to know well (seasonal fruit and veg etc, once upon a time you just didn't have strawberries in winter), then along comes industry and global commerce and says "you can have whatever you want, whenever you want it, we just have to use a whopping amount of energy to do so" - that was fine when you had a small population, but harmful at the scale it now runs at.. That needs to change; the expectation that we can always act as we have done the past 100 years, is just lunacy, and worse that the "third world" looks to follow in those destructive footsteps, as they strive to catch up with western ideals and life patterns.
