The EU a few years ago set “green” caps on the amount of power manufacturers could use in household appliances, cutting the power available to consumers in such items as microwaves, irons, toaster ovens, vacuum cleaners, crockpots, hair dryers, electric tea kettles, etc. There has been a huge outcry in the comments sections in British papers, with most observing that you have to use the appliance twice as long to get the desired result — not “green” at all. Further, the EU tried to junk all older appliances on a deadline, costing consumers a lot, just like our switch away from analog tv and incandescent light bulbs. I can imagine that Dyson’s re-engineering costs were substantial.
The EU set mandatory hot water temperature limits at the same time period: Makes coffee and tea colder, less palatable after a few minutes in the cup or thermos.
