Think about the city you live in. Everyone uses a lot of electricity to power their lights and electronic devices. The WWF (World Wide Fund for Nature) started a global event called Earth Hour. They designate an hour every year and ask households and businesses to turn off the non-essential lights and electronics for an hour. In 2011 all seven continents participated and electricity use was greatly reduced. What if there was a city that rarely ever used electricity if at all? It’s carbon footprint would be a lot less.
