I'm in the process of moving over to LEDs. Mostly because I'm not sure for how much longer I'll be able to get the incandescents that I like. But... also because LEDs are supposed to last forever (jury is still out on that one) and run more cost-effectively (that's certainly the case). Nothing eco-whatever in my decision process. Just a desire not to goof around on a stepladder any more than necessary, and save a few bucks while I'm at it....
But I think that Knarf was on to something with the "we're using less, so we're producing less". There's an awful lot of buildings sitting empty in my neck of the woods. Lots more manufacturing and retail-related empty property, as well.
Our church relamped with LED’s. The energy saving has been quite dramatic (I’m told close to 80%!)
In a related item, a wind turbine factory about an hour from here is closing up shop.
