A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.
Possibly from allowing sunlight into the building which heats the interior. Air conditioning must work extra hard to overcome the heat.
But in the winter that takes the burden off the heating system, as long as they're using windows with decent insulation.
