I turn off lights and appliances when they aren’t in use. I often don’t turn lights on unless it is absolutely too dark to function. Some people have this habit and some don’t. Though I can be smug about this (what I see as an) attribute, I can also be smug about turning off the lights when people leave them on.
I’ve spoken with people about this before and I asked how this energy saving mind set came to them. Some credit their Hippy parents. Some credit the energy crisis of the 70s. There are all sorts of reasons out there but mine is a little different.
I once had a bicycle with a headlight on it. I could have gotten a battery powered light however batteries were different in those days. They didn’t last as long as the Alkaline batteries we use these days. Sometimes twenty minutes was all you could get out of a battery powered lamp.
My bicycle light was powered by a generator which was a device that you clamped to the frame of your bicycle and when you needed to use the light you would slide and lock the turning wheel of the generator into place. The wheel would rest upon your tire and as the bicycle wheel turned the generator wheel would be spun by the bicycle tire. The problem was that these generators took so much energy to power one light bulb that it was tiring. You would even have to peddle while going down hill.
Yes, products now consume much less energy to get the same results, but still, can you imagine what sort of effort one would need to put out to power a toaster?
I’ve been to some museums that have devices that let the participant see exactly how much effort it takes to power a single light bulb. Everyone who tries this will think differently about leaving lights on.
