Yeah, this isn't entirely fair. We use the 3-hour cycle on our washing machine all day because that's the one designed to take a full 6-7 kg load (oddly enough, the "eco" labelled cycles on our washer only take 2-3 kg... not very practical for a family of five).
But we also drive SUVs because we need cars that large to take our entire family places, and they're older models because that is what we could afford to buy, even after taking out a loan. We each have a car because the public transport offering in our city does not meet our needs (in our case, the busses don't come frequently enough, all busses lead to the city centre, good luck if your office is in the suburbs on an industrial estate).
Our utility bills go to a company that supports renewable energy. But we use a gas boiler to heat the house. We do not have £10,000+ just sitting around somewhere that we could use to swap to a heat pump, hydrogen is years away from being rolled out, blue hydrogen is even worse in terms of total CO2e output, green hydrogen is still a concept rather than commercial, and the safety risk of hydrogen has yet to be communicated clearly to households. So... we could freeze, I guess? I already have the thermostat turned down to 17C, but eventually we need to burn hydrocarbons to heat the house and have hot water.
We can and have been eating more plant based meals. But we cook them on a gas hob.
Do our own personal habits need to change to make a better world? Yes, they do. But we also need to be set up for success, which AFAIK is part of the call for a "just transition".
I'd gut the house and put in a heat pump and associated pipework tomorrow if I had a grant for it. Or even an interest free loan with a long payback term. But at £10,000 minimum, that financial support has to cover far more than half the cost.
