Well, that's the problem. It's not just that one manufacturer's bread
that is supersized. It's that many toasters cannot fully accommodate
slices from any large loaves.

I blame the EU myself.

It's not the EU but if they pass energy use rules for toasters, the obvious approach to conformance will be to reduce the slot size.

The idea that they considered energy rules for kettles is almost amusing. Water takes the same amount to reach boiling no matter what you do, and ambient heat loss is trivial.


* Variable heat kettles - not everyone needs boiling water (weird teas
for example);
* Quicker auto-off. It does not take all kettles of the same rating the
same amount of time to reach boiling and swithc off;
* Decreased minimum fill;
* Improved heat retaining insulation.

Bosch do one IIRC, for a price. As (I'd guess) one of the biggest
consumers of domestic electricity, I think it's a very good idea to take
a look at kettles.

Whether the EU does it, or the UK, I don't really care.

2-3 minutes to boil 3x a day at 2.4kW. That's 0.24-0.36kWh/day or 3.1-4..7p/day = £11.38-£17 a year.
Now what are those features going to save, 50p? £1?
What are they going to cost? £10? £20?
How long is the kettle going to last?

Wrong questions..

how much can you reduce the peaks in demand and will that save investing
in another electric mountain?

Those features aren't going to make a significant difference to peak power use. Let's be optimistic and say a quicker stat cuts 5 seconds off boil time out of 2-3mins, that's at best 1.7-2.5% trimmed off the peak. 40 million superkettles is an extra £400-800 million.
