I don't think it's so much that people refuse to make changes. It's more that we often don't know what difference any changes could make. I didn't really know how the eco wash worked until reading that other thread. To me, eco wash equalled the not washing properly wash. I thought it was just that the temperature was lower, not that the drum agitated less and so needed less electricity.
Other changes aren't possible for people to make. Lots of people just have one set of bedlinen so they need to wash on a quicker wash setting and use a tumble dryer. I've got more than one set so can line or air dry but have myself contributed to climate change because of the bleaching needed to make cotton white, buying more bedlinen than I actually need etc.
I heard a good interview with Brenda Boardman, an expert in domestic energy use, the other week. She said that private households are only responsible for 25% of UK energy use - fitting in with what others have posted above. However, she phrased it positively in the sense that we might all (might not must) be able to make changes.
The key thing is for manufacturers to use technology to make changes to appliances to make them need less energy. For instance, the motors in vacuum cleaners now use less energy and I can't say I've noticed a difference in performance.
Other things aren't in our control. I didn't choose to build out of town retail centres, large district hospitals, and housing estates which mean that people don't have any choice but to have a car. There was another thread this week about schools and the petrol crisis and a decision by one secondary school to insist children and teachers living fewer than 6 miles away should walk unless they had a physical disability. 12 miles for an unknown number of days in a row. I was quite relieved not to work there!
As a childless woman, I thought the comments about having children a bit
. We do need to replace ourselves to survive! I'm grateful for other people's children who provide health care, educate the next generation, deliver groceries, and all the other things we need to keep society going.
For me, changes are more about helping us make educated choices (wear clothes more often but use a hot wash or wash more often but on an eco setting). I accept that almost all of us do what we can. What's feasible for one person doesn't work for another.
