This was one of my first maps, made it about a year ago. And it’s still one of my favorites.

"A grid-aware website responds to the cleanliness or dirtiness of a user’s electricity grid, i.e. whether it's currently using more renewable energy or fossil fuels."

This is not CSS grid-aware, but energy grid-aware websites. Websites that respond to the “cleanliness” of the user’s local electricity grid. A very interesting read and concept.
