In Denmark, it’s probably intuitive to say:

1. We consume less energy on warm days between 0100 and 0300 hours.
2. We consume more energy cold days between 1800 and 2000 hours.
3. As temperature drops, the consumption increases. This increase is marked at 5 to 10 degrees.

But it’s really cool to watch it in 3D. Click on the image to get a 3D figure that you can play with :)
