Unfortunately, I don't think the consumer is ready to give up their car-dependent lifestyles or to take the kinds of steps it will take to really make a difference. We can't even get people to replace incandescent bulbs with flueroscents!


We found an interesting article about the problems with Ethanol on

"But there are some problems with increasing ethanol blends. Ethanol contains less energy than gasoline, so increasing the amount of ethanol in gasoline will likely result in lower fuel economy. Increasing standard fuel blends from zero to 10 percent ethanol, as is happening today, has little or no impact on fuel economy. In tests, the differences occur within the margin of error, about 0.5 percent. Further increasing ethanol levels to 20 percent reduces fuel economy between 1 and 3 percent, according to testing by the DOE and General Motors. Evaluations are underway to determine if E20 will burn effectively in today's engines without impacting reliability and longevity, and also assessing potential impact on fuel economy." would like to invite readers to post their own views and ideas in's Investor Forum:
