missinformation and out-of-date thinking are ripe here, as CCdeniers and fossilfuel FUDs rule the worm riddling brains of the terminally thick...
People still talk about issues "with kettles turning on during the world cup" or during the advert breaks in East Eneders of what ever, but this is tragicaly out of date. The problem back them was two fold, 1) lots of people all doing the same thing at the same moment which is not true any more as we are no longer welded to our living room tvs at 7.00pm exactly syncronised by terestrial live telly and 2) our mostly coal fired powerstartions took ages to ramp up / down due to their massive thermal inertia. Our grid is much more dynamic and agile now, so the problem of it being a weekend with little industrial load (the major consumer of our electricity) and hence coal fired stations being at idle, and then everyone having a cup of tea at world cup half time are long gone.
We also have a much better arrangement of load spreading. Most loads are actually "shedable" at the right price, even loads you might consider important. Huge inductrial users are lined up for, and get a good cost saving from, specific deals that mean they get shed first, keeping the "lights on" for the general public.
It's also worth noting that "blaming everyone else and just moaning" doesn't get you anywhere in life. The grid powersupply to my house and this computer could stop right now and i wouldn't even notice, because i have a second hand EV battery and solar array that can run my entire house for several days (hint, EV batteries are massive, my Gen2 nissan leaf battery was 42kWH when new, and now some 7 years later at the C rates it sees for my domestic application it's still capable of buffering around 39kWh of energy, and it cost just £1,800. It actually has already paid for itself because i use no "expensive rate" 'lecy at all now. I use roughly 50% from the solar and 50% from the grid, but charging at the cheapest off peak rate has quartered by 'lecy bill.
So if you see "renewables" as a problem that's fine, but the actual problem is that you are stuck in the past............
