Ok, let me explain something. By environmental costs I mean energy.
The left-wing government that preceded the current made it very difficult to create new power plants. Oil/coal/nat gas plants need to be fitted with a form of carbon capture that hasn't been invented yet. Nuclear power plants take ten years to build, and people have problems with nuclear waste. Also, everyone (wrongly) seems to think that nuclear fusion will be a feasible source of power in the near future. Renewable sources: wind is very unreliable and insanely expensive, solar is also unreliable, tidal is extremely expensive and not enough studies have been performed to determine efficiency.
UK power stations work 100% 24/7 through the winter, at day supplying the houses and at night transporting water up into massive lakes so that instant hydroelectric power can be provided when it's needed. Which is at least five times a day.
Now I hope you understand that when (not if) we finally exceed our power capacity in the UK and need to employ rolling cuts, I don't want oversized freezers to be in operation while houses, streetlights, railways (particularly underground), security systems etc are cut.
I'm just as against all the other fridges in the UK, but I'll still use them because they're there and I can't stop that.
Also remember that this is a minor point in my argument.
