I understand that the little things count. But the op is asking about what changes can be made to save money on his power bill. At 10w it would take 4 days to use 1kwh. 16 days roughly to cost 1$. Heaters, return pump, and lighting are the worst aquarium related. If he wants to make an impact on his power bill, the rest of the house needs to be looked at. A 3 bulb light fixture with incandescent bulbs draws as much as a return pump. I have 4 in my 860sq foot house. How long are lights like that run in a day?changing to cfl bulbs (twistys) draw less than 1/4 the power. Electric range and oven? Probably draw 10+ amps when running. That's 1200w. Electric dryer, same story. These aren't ran continuously mind you, but these add up. Natural gas is far cheaper to run these things.
Those are the changes that are going to make an impact. If your talking about environmental impact, then again, how effective is cutting 8w out of daily power usage when there are so many things worse. I used to work on a drilling rig that used diesel generators. In the winter with the boiler running that rig would burn 2800 liters PER DAY in diesel fuel. This is a larger rig mind you, but there are over 700 running in Alberta last time I heard. These are thtw kinds of things that need to change. Alternative renewable fuel sources. I'd hate to see what kind of pollution 2800l of fuel burn would produce.
I'm not saying that its not worth looking into the little things, but my point is the big things need to be looked at first. 250w down to 100w has me now saving for a new return pump now. I've already switched to leds which for me went from 260w of power compact lighting to 160w of leds.
The next big question is heating. 400w of heaters running is worth looking into.
