Saving Energy?

There's a UK home energy crisis in terms of the ramping costs for electricity and gas, as well as the associated climate-altering emissions. It's consequently helpful to get expert advice on 'burning' questions (https://www.theguardian.com/money/2022/mar/29/cheaper-bath-shower-energy-questions-answered-reduce-bills). The following nuggets appear useful:- 1. money is saved on home heating, by turning it off when it's not required (reheating an abode from stratch, isn't actually a costly option); 2. more than 20% of UK home electricity, is used by 'vampire' devices (chargers left plugged in or items on standby); It pays to unplug mobiles, TV's, computers, electric toothbrushes, razors etc as soon as they are fully charged (it also extends the lives of their batteries); 3. it's cheaper to have a brisk shower than to wallow in a bath; 4. washing machine laundry can be efficiently done at less than 40 degrees Centigrade, if modern powders and detergents are used; 5. it's a good habit to turn off lights, when leaving a room but LEDs save lots of energy anyway and 6. when cooking, microwaves are more efficient than electric or gas ovens. Having said that, at current prices, gas hobs may be cheapest when boiling water to cook pasta. It all seems to involve a great deal of plugging and unplugging!
