Some people need a constant reminder to turn off the light (I will admit that I probably fall into that category). Now, with the Sustainable Habitat Reminder stickers from London-based Hu2 Design, you (and I) will never forget to flick the switch.

The Sustainable Habitat Reminder stickers are funky home decals meant to raise awareness about energy consumption. The motif shows the inner workings of standard plugs and switches, with images of lightning and generators added to the mix. Stick these to your wall (or toilet) and you'll never forget about energy efficiency again!
