Here's a question that I've not heard anyone ask before: Gasoline prices in countries such as the United Kingdom and Norway can sometimes reach $5 per gallon-because of high taxes. According to the Wall Street Journal, taxes in the United Kingdom account for 80 percent of the pump price, while the Europe-wide average is between 60 and 70 percent. In Germany, gasoline taxes account for a whopping 20 percent of all government revenues. Cool. So every 48 aluminum soda cans that you recycle are the equivalent in energy savings of one gallon of gas. Therefore, you should make one of these.
