Day 20: What you can do today
This is a hard one: Keep your highway driving speed between 55 and 60 mph today. For most vehicles, 55 mph is the most fuel efficient highway speed and will save you up to 20-30% in fuel costs compared to driving at 75 mph. Automobile emissions are one of the leading causes of greenhouse gases. Don't idle your car at traffic lights and drive-up windows. If you have to stop for more than 10 seconds, you will save gas and reduce greenhouse emissions by turning off your engine. |
