Back in 2008, when the banking crisis hit, an employer I worked closely with had to close. They had over 100 years of trading, and it wasn't that their product was shite (far from it), it was their overheads. Power/fuel bills etc.A Michelin-starred restaurant in Dorset has been forced to close with "immediate effect" due to rising costs.
The Fontmell in Shaftesbury, which was listed in the 2022 Michelin guide, explained that supplier costs had increased to such a point that it was "no longer able to pass that cost" onto its customers.
In a message on the pub's Facebook page, the owner revealed that the pub's utilities alone have increased by £58,000 per year.

The first law of thermodynamics is we don’t talk about thermodynamics.I’d like him to explain how it’s possible to improve the efficiency of a process where electrical energy is converted to heat. What is the energy byproduct that is wasted that could be reduced?
It’s not like going from a tungsten lightbulb to an LED where the saving is all the heat not generated. In a kettle, the heat is what you want.
I suspect he needs to familiarise himself with the first law of thermodynamics.
I kind of disagree with you here, a 1 bar electric fire uses 1 KW per hour and produces 1 KW of heat.I’d like him to explain how it’s possible to improve the efficiency of a process where electrical energy is converted to heat. What is the energy byproduct that is wasted that could be reduced?

If an element is more efficient, where does the wasted electrical energy in the inefficient element go?I kind of disagree with you here, a 1 bar electric fire uses 1 KW per hour and produces 1 KW of heat.
1 KW of electricity used by an air to air heap pump (like for instance a reverse cycle air conditioner) will give you 3KW of heat for 1 KW of energy used. (average COP is 3.2 KW).
An example of technical advances using electrical energy.
I've been saying for years that people in cold countries (like the UK) should be heating their homes with Heat Pumps, not inefficient Gas/Water systems. Much cheaper and instantaneous heat.
I think what Boris is alluding to is new kettle's are/can be more efficient than old one's, that could be through materials used, or the element being more efficient thereby needing less time to boil the water.
Some energy is lost through the heating of the kettle itself AND the surrounding air. Better materials with a more insulating effect can improve efficiency and eliminate these loses.
Technology is always improving and new appliances are generally much more efficient that old one's. Boris isn't wrong on this.
My new fridge/freezer uses about half the energy of my old one. Because it has Inverter technology rather than constant stop/start of the old compressor. It also has improved insulation all over it.
The element will not be any more efficient. If you buy a new 1KW kettle to replace your old 1KW kettle, it will make hardly any difference what so ever, assuming you have not decided to chop the top off the kettle for some unknown reason.I kind of disagree with you here, a 1 bar electric fire uses 1 KW per hour and produces 1 KW of heat.
