exercise

Turn everything off in the house then go for a family walk.

You get fit, power gets saved and you can do something together as a family.

In the evenings, turn off all the lights (and heaters and TV etc) in the house and play "scary monsters hide and seek".

If you work four floors or lower to the ground, abandon the lift and take the stairs - up and down. If you work with people one floor away, abandon the lift and take the stairs both ways.

We have newly moved house into what could be called, hmmm, a frozen old villa?

When my lawns need mowing, I wait for a nice day (there's still plenty of those even in winter!) and mow them by hand with my hand mower instead of using my electric mower.
