It seems like one of the biggest challenges in the current energy issues, whether it's oil independence or global warming, is how to get people to use less energy. I think that there is a simple way to get North Americans, at least, to cut down on their energy uses if only I could convince all the planning and zoning committees to agree (we could always tie it to a bill, and say we'll withhold road funding or something if they don't do it...that's how come the legal drinking age is the same across the US).
Water & Electricity cost money. North Americans are notorious for always wanting to "save more" money. However, most North Americans have no clue how much water or electricity they use in a given day. So let's place water & electrical meters by the front door at about nose level where people can see the numbers changing daily. Better yet, make those meters look like your gas pump where next to the consumption level you have the amount of money that consumption costs. If people saw this daily I suspect they would immediately start to reduce their usage. Imagine if every faucet and outlet/light switch had a little meter by it that ran with amounts used and money charged by it? People would start turning off their lights when they left the room, they would stop leaving the water running while they brushed their teeth. Family members would start nagging each other to do these things.
What do you think? Would it work?
