Volodymyr Agafonkin and his family live in Kyiv, Ukraine. He visualized when the power went out over the past two months:
As you can see, we spend 4–8 hours in blackout during a typical day. You can notice some stepping patterns in the data — this is our energy workers trying to stabilize the blackouts into some kind of schedule, although it’s often overridden due to emergency shutdowns. More blackouts happen in the evening time because of the increased load on the grid, with everyone getting home after work and cooking dinner. There’s usually no need for blackouts at night because people go to sleep, and the load falls sharply — that’s usually the time for us to charge devices, turn on the washing machine & dishwasher, and occasionally bake something nice in the oven.
