It is an interesting comparison, but measuring how much and where you use energy can help you to make unexpected choices.
Did You Know that... A full standard kettle (1.7 litre, 2.2kW) takes 280 seconds to boil and uses 616kJ (0.171 kWh) of energy. This is only 1.7p, at an electricity tariff of 10p/kWh.
This doesn’t sound much. But if you boil 10 kettles per day for 300 days per year, that is £51 per year. However if you use only half of each kettle because you only actually need water for two cups of tea then you will waste £25.50 in a single year.
One of my previous blogs suggests that I will save £51 each year having replaced all of my existing windows with double-glazed units, in a mid-terrace three-bed house. This is at a capital cost of £10,000.
But I can save half of this amount each year simply by changing one part of my daily routine and half-filling my kettle each time that I use it. Which is easier in your opinion; replacing my windows or remembering to half-fill a kettle?
I am coming to the belief that changing my pattern of behaviour is central to successful resource management.
Do you have other examples to share of simple changes that can create similar positive changes?
