AskPatty’s Tips to #Green Your Car and Save Gas: Park Green
Park in the shade or a garage whenever you can.
The cooler you can keep your car while it's parked, the less fuel you need to use to run the air conditioning to cool it off when you start driving again. Parking in a garage also decreases the energy needed to warm up on cold winter mornings. If you can't park in the shade, consider using an electric or solar car fan, or a reflective windshield shade to help keep your car's interior more comfortable.
