Don't ask why - just switch it off!

I was interested to hear on Scottish radio ads from the fire service urging people to turn off and unplug all their electrical appliances at night in order to reduce the risk of fire. Of course, this will also stop them drawing power when not actually in use - but how many of us actually do this? Is the risk of fire a bigger motivator than the risk of climate crisis? And if so, how many other environmentally preferable actions could we be persuaded to take if they were presented to us under the guise of an entirely different benefit?
