How much do I pay for electricity?

So I’ve been looking at my own transaction information with Maritime Electric, pulled using the code I posted yesterday and here are some of the things I’ve learned:

• Over the last 11 years we’ve paid $13,457.99 for electricity for our home in total.
• The most we’ve ever paid for a month’s worth of electricity is $202.68 in February, 2003. That was the winter of a very bad series of winter snow and ice storms that caused ice build-up on our roof; one way we tried to mitigate the damage was with heating cables on our roof, which we ran pretty-well full-time for a month.
• Later in the spring of 2003 we were in Spain from May 3 to 17, 2003; our bill for the month covering that period was only $21.13, the lowest bill we’ve ever had (which isn’t quite as “we used almost nothing” as it seems because we’d paid an “estimated bill” the month before of $148.34 which was presumably inflated by the expectations our February demand placed on the amount).
• We use more electricity in February (average of $114/month) than in any other month; in June our average usage ($68/month) is almost half of that.
• I consider myself a pretty “pay my bills on time” kind of guy most months, but I’ve managed to accumulate almost $100 in interest charges due to late payments over the last 11 years.
• We contributed just over $700 to the Green Power Program that started in 2001 (I cancelled our contribution back in August; I figure wind power has enough legs to stand on its own now).
