Roll your powered windows up before parking the car. It wastes fuel when you park the car and then you have to keep the car running to roll the windows up. Yes, you could turn off the engine and use the battery to roll up the window, but that electricity is generated by the engine to begin with.
The energy taken to roll up the windows comes from the engine. If it must go back into the battery because you rolled the windows up with the engine in park or if it had to come from the engine while driving to your parking spot through the alternator it makes little difference. I do agree that it uses more fuel to idle the car just to roll up the windows.

Similarily you could shut the engine off and coast into the sport.
