Mario Lewis on the Renewable Fuel Standard. From Global Warming.org, EPA’s Renewable Fuel Standard Proposal Ignores Root Cause of Blend Wall
10% seems to be the limit unless they go to E85. USDA is subsidizing E85 fueling to the tune of $100 million. And if you go to E85? The annual estimated fuel cost estimate increases between $800 and $1300, depending on the vehicle. So, there is a limit, but the limit is how much we spend.
So even if every gas station has an E85 pump, consumers will avoid the fuel in droves, because it is a bad buy. Lower energy content, inferior fuel economy, and higher consumer cost are the root cause of the blend wall. The same factors also explain why the “choice” to buy ethanol must be mandated.
And the CO2 emissions from corn ethanol is higher than equivalent energy from tar sands. Such a choice we have.
