Michael VanDaniker found that his energy provider, Baltimore Gas and Electric, provides customers with an easy-to-use tool to export their home’s energy usage by the hour. So he downloaded the CSV and had a look back at 2015, through the eyes of heating and cooling. Fun.
By the way, is this data availability a normal thing these days? I was surprised that BGE provided an export tool, but then I checked my energy provider PG&E, and they have one too.
