Electric Usage and Temperature

Figure 3. Temps (blue) given on the left vertical. Electric usage (red) given on the right vertical

When the temperature (blue) is high, the electric use (red) is low. Contrariwise, when the temperature (blue) is low, the electric use (red) is high. They have opposite seasonal trends.

Heating Electricity Usage

I was surprised. This chart of our electricity usage by average outside temperature shows a wide variance in our usage at the same temperature.
