Our household participated in Earth Hour today by turning off all the lights, computers, and TVs between 8:30 and 9:30pm. What to do, when you would rather be bookbinding? I planned ahead, made sure that my solar-powered book light was charged, and spent the hour reading some Szirmai.
This book light is a handy gadget - check it out on Useful Things. (The bendy wire can be argumentative but the light is good and stays charged for a full earth hour and more.)
Happy Earth Hour! What did you do during earth hour?
