A gent has created some software you can use in conjunction with your webcam to monitor your electricity usage. For £5.00, you load the Calc-Electric program onto your PC and point your webcam at your electricity meter. The cam optically reads the data and the program charts what is being used where at what cost. You can export the data into an Excel spreadsheet for long-term analysis. The only obstacle seems to be the location of your meter, which for most folks is not within spitting distance of the household computer.
