I'm going to make an unusual foray into environmental responsibility here.

Folks, everyone listening.

If there's a do, a simple thing you can do, two things.

Put on your appliances at times when there is an abundance of clean electricity.

You don't have to change what you do.

You just have to change when you do it.

Secondly, if you've got a dryer that doesn't have a heat pump, get a dryer with a heat pump.

Because, yep, it's slow.

I'm going to acknowledge that.

It's not as fast as an old-fashioned dryer.

However, the energy efficiency of a dryer with a heat pump, or better still, Americans, if you live in Arizona, dry your clothes outside.

Because this is something that's slightly bemusing, because in Britain, we didn't have the social stigma of hanging clothes up to dry.

to the same extent.

Now, we do now.

Nobody would hang clothes up.

But that's just a social stigma.

Now, in Britain, fairness, we've got a fairly climate.

You're Canadian, OK?

There are plenty of times of the year where your underpants can be hanging there for three months.

They might freeze, but they wouldn't noticeably dry.
