Today supporters of the WWF will be turning off the lights for Earth Hour. When it turns 8:30 in your neck of the woods consider doing the same.
This video from late last year talks about futurisitc and energy saving highways that might start to be built in the Netherlands this year. It’s a good match for Earth Hour as it’s all about using lights only when they’re needed.
The recharge lanes, I suspect, will be a while coming but the photo-luminescent paint and the wind lights both feel very do-able with today’s technology.
