PG&E Home Energy Stats

Our energy provider is PG&E, though we opt-in to the MCE Deep Green program to ensure that 100% of the energy we use is sourced from wind and solar (it’s like having solar panels without having to own your own inverters). Went looking on PG&E’s web site last night to see how owning an EV has changed our electricity consumption over the past 1.5 years and was blown away by the quality of the data access and visualizations they provide. You can download billing and consumption data in CSV or XML for any date range, for import into spreadsheets or so you can build your own web app. But why bother? They offer a huge range of ways to view your usage data over time, to compare your usage to similar homes, to view electric, gas, or combined. They overlay weather data and plot-lines to help explain usage spikes. Super well done. You can fine-tune your home’s characteristics for better reporting accuracy.

The answer to my original question? Pretty much zero. Driving an EV has had negligible impact on our electricity consumption, which means I’m basically driving for free (though granted I sometimes take advantage of the charger in the work parking garage). Shown: How our natural gas usage increases in the winter months.
