Jono and then Graeme pointed me at Google’s energy information project, which looks very much like something I’d be interested in.
Specifically I was wondering if it was possible to take the data from something like Wattson and using some heuristics or some kind of Fourier analysis to detect what appliances were consuming electricity. And better still, compare that against what’s possible and, perhaps in some cases, suggest it’s time to dump that highly inefficient model of refrigerator and replace it with a new one 🙂
But anyway… I don’t know what Google are doing, but take a look at the graphs they want to produce. They looks useful to me.
Graeme also pointed me at HomeCamp: it’s a hack day/unconference, around the theme of energy monitoring.
