Blackouts

We seem to be having a lot of electrical blackouts recently. Last night the power went down at 7:30, came back on for twenty minutes at 9:10, and then went out again until sometime after midnight. It is really hot at night in my room if the ceiling fan is not working. This morning there was power when I woke up, but then we lost it for about an hour between 10:30 and 11:30. We seem to be losing power more frequently and for longer recently. Maybe because it is hotter this time of year and there is more strain on the electrical grid from the running of air conditioning units.
