Therefrore its easy to see that 'energy saving' low power kettles
would actually increase energy consumption.



Who has suggested limiting the maximum power of kettles?Â* It strikes me
as a straw man.

The suggestions I've seen from the EU work may or may not prove to be
cost-effective but they are at least literate - eg

More concealed elements and more accurate scales to heat less water

totally pointless. Existing kettle can heat less than a cup of wtaer.


Reduce switch off time after reach boiling

Oh purlease! 2 extra kilowatt seconds? At ehat extr complexity and cost
and energy to manufactire?


Reduce thermal mass of kettle

Already minimal compared with water.

Reduce outer surface heat loss


Totally pointless. Kettle is only hot for a few seconds.




And how much energy will it take to manufacture a kettle with all that?
