Recently I was thinking that it would be interesting to take a look at the amount of energy I use (and generate) to see how it varies over time. I already had daily data for my electrical and gas use, but thought that it would be interesting to see if this correlated to the weather. Luckily I found a weather station near my house that had a treasure trove of data, including solar radiation numbers. It took me awhile to pull all the data together, but I was able to come up with an interesting set of charts. I'm also trying something new in this post by embedding the charts directly, which should make them interactive. Let me know how it works for you!
