Plays the chart through its history, period by period.

EIA Hourly Electric Grid Monitor (Form EIA-930), demand served by the grid as balancing authorities report it, summed by EIA region. Rooftop solar and other generation behind the meter lower it. Regions follow balancing authorities, not state lines, so each state takes the colour of the region that serves most of it.

Twelve months of electricity use against the twelve before, region by region. A full year in each window cancels the seasons, so the colours show where load is actually growing: data center clusters, new factories and electrification show up here first.
