Its interesting that oil is at $87 a barrel and yet gas is about $4 a gallon. In 2008 oil was about $147 a barrel and gas was $4 about gallon. Anyone else notice that when oil goes up the cost per gallon goes up quickly as "a result" but it never really comes back down. Its also interesting to hear reports of studies that say that $4 a gallon seams to be the breaking point for people where they will drastically change their habits/life to reduce their gas purchase. Anyway the reason I want one is I believe they will over all produce less pollution, which is nice, and will be more insulated from the rising cost of gas, my main reason. I am in Illinois now and there is a coal powered plant nearby, yet in oregon my previous state there was so much rain last winter that they had to shut down some of the power plants because hydro was producing way more than they could even use.
