Got electricity bill today, and I'm happy: 20% reduction in total electricity usage from last year. I'm not quite sure what helped, but I think that figuring out how I use my computers was a major factor. We now keep them off (or in hibernation) most of the time when they're not used, and my desktop just wakes up at night to run remote backups, after which it shuts itself off again. You can save a surprising amount of energy by spending an hour or two twiddling the computer power-management setup. Also, using laptops more (now that we have two) probably also contributes quite a lot: a typical laptop takes about what, one fifth of the power of a regular desktop computer (60W vs 350W)?
The in-house sauna also lost some of its novelty value, and we cut down on using it to maybe two-three times a month. This was also probably the other major power-saving.
Now, I know we can do better this year, though the upcoming kid is going to make it difficult. What I would like to do is to have better measurements with immediate feedback. I know there are already companies offering that, but it seems to be quite sluggish to get the equipment installed when you're living in an apartment block...
