You may know that CA ushered in a Cap and Trade system on gasoline manufacturers under Assembly Bill 32, which became effective yesterday and is expected to increase the price of gasoline by $0.10 a gallon. As chance would have it there really couldn't be a better time to start doing this than right now, with the price of fuel nearing historic lows over the last few months and a (slowly) strengthening economy. Most will notice the increase in the price of fuel but may still be happy enough to be paying much less than they did a couple of years ago. Only those really clued in to what's happening are likely to understand why and (predictably) will either be OK with it or upset about it, presumably along political lines.
