Indeed (give or take the correct to units that Detlef has mentioned)Call it 10w for the router, run for 24 hours that will be 240w/hours. I000w/hours generally costs around 28p, so your router costs you 6.72p per day to run. Is it worth your effort to turn it on and off, morning and night, to save what might be the 2p overnight running costs?
Very much so. For example, for those using a 10.5 kW electric shower, the same saving (~2p per day) could be achieved by reducing the total duration of showers by about 25 seconds per day. I can't be bothered to do the sums, but imagine that at least the same amount (probably more) could be saved by not boiling more water in kettles than one needed ... etc. etc.Your nest, running cost figure will be similar. There are much more effective ways to reduce consumption and save money, which you ought to implement first.
If you switched your kettle off just before it boils (96c instead of 100c) lets say 4 seconds early
2200w / 60 / 60 x 4 x 28p = 6.8p per boil
lets say you boil the kettle 10x per day, so just switching it off 4 seconds earlier (better temp for coffee) this could save a whopping £248 per year (this is a worthwhile saving)
if all kettles in europe were designed to switch off at 96 instead of a 100 we could probably tell putin to shove his gas where the sun does not shine.
That would be nice but, unfortunately ...If you switched your kettle off just before it boils (96c instead of 100c) lets say 4 seconds early

pesky decimal point thingies - I blame the weather for mad error - scorchio hereThat would be nice but, unfortunately ...
2.2 kW / 60 / 60 x 4 x 28p = 0.068p per boil
Nevertheless, as I recently wrote, there are appreciable savings to be had by not boiling more watre than one needs.

... and here! No problem, and I was not 'criticising' (hands up anyone who has never got a decimal point in the wrong place ) - but I thought I should put things right, for the benefit of other readers!pesky decimal point thingies - I blame the weather for mad error - scorchio here
Indeed, even if his calculation had not made the potential saving 100 times greater than it actually would be However, again, I think appreciably savings are to be had by not wasting energy boiling more water than one needs to boil.Problem is, kettles use the boiling of steam to reliably switch themselves off and so need to boil to trip.
