Why don't Americans use electric kettles? - YouTube
Another take on boiling water, this time from USA.

That's a 25 minute video! What's the main point?

It's not just any 25-minute video, it's a Technology Connections 25-minute video.

Thy're usually great entertainment, if you're a bit geeky.

Edit 30 minutes later:

Well that was a fun video, we should make sure it gets posted every time one of these threads comes around.

Main points:

• Americans rarely have electric kettles because they don't often make hot tea.
• Electric kettles are more efficient than electric hobs, which are in turn much more efficient than gas hobs.
• Even a 1500W kettle will boil faster than a stovetop kettle on a 2kW electric ring or a 5kW gas one.
• An induction hob is a little less efficient than an electric kettle.

I just boil enough water for the required cups of tea. Filling flasks is just absurd. LOL.

But the question is... should I replace my 20+ year old kettle for an up to date modern more energy efficient kettle?

Only if the new one has a snazzy blue light

The point is that he's done the experiments and come to a definitive answer. - leccy is faster and uses less energy, however you need to decide whether the higher cost of leccy offsets the waste of gas  . Off course its up to you whether you are interested enough to watch it = https://www.youtube.com/watch?v=_yMMTVVJI4c

Actually it already does  infact it lights all the water up blue while it's boiling, it has a large viewing window, it's cordless and swivels 360 on it's base. Think it was top of the range when new although I didn't buy it.

so for maximum savings always refill the kettle after using it, not before using it.

Nooo.....for a decent cuppa it has to be freshly drawn water each time and don't reboil.  I can live with putting an extra jumper on to save a few pennies but not with a lousy cup of tea just to save less than a penny extra a time

So water that has been sitting in a pipe for 6 hours is perfectly fine, but not water that's been sitting in a kettle for a couple?

The water in a kettle is still water whether it has been boiled none or 20 times.

Some say that for the best cuppa you should only use bottled water that was extracted from a natural spring by naked virgin females... I bet that costs a bit...

It's the dissolved air that's lost on boiling, or something like that. It definitely tastes different.

It really depends on the quality of the water you are drinking, all water will taste different - bottled water vs tap water for example.

The chemicals found in tap water do change if you reboil water which may cause a taste difference, but my original comment didn't mention reboiling water: I said refill the kettle after making a brew to save money. The idea is that water at room temperature will take less time to boil and so cost less.

And the water used to refill straight away will get heat from the still hot element and inside kettle surface.

Full kettle. 
Make a full pot of tea. (1 tea bag, if you like it strong leave a while) take out once at required strength. Leave pot on side.
Then as you need a cup of tea. Fill cup & just put in Microwave for 30 secs. 👍

Heating the water twice certainly isn't energy saving!
