A one-day "gas out" means nothing. If you want to make a difference, cut your fuel usage by 1/4 PERMANENTLY. If everyone would do that, demand would deline so much that the supply would be able to handle it, and the price would plummet.
Easy ways to do this:
Only go shopping at markets close to you, and only shop once a week, buying everything that you need.
Move closer to where you work. More than half of all driving is work commute. If you cut the distance you drive to work in half, then you cut your fuel usage by 1/4 automatically. I live 5 miles from my office, intentionally.
Move to Buenos Aires, and walk to work. LOL
