This is the political way....as are the Ethanol subsidies, (Iberdrola). (Top state/local subsidy recipients) "Of all the state and local subsidy dollars tracked, half went to the top 30 companies, led by Boeing. The aerospace giant alone has received $13 billion in subsidies. Chip-maker Intel and metal giant Alcoa each received nearly $6 billion. General Motors scored $3.7 billion and Ford secured $2.5 billion. All told, 19 large corporations have received at least $1 billion." Obama doesn't mention these icons of industry having to be subsidized....and the left wants to put a ban on energy?
In other words, ethanol is a carbon based fuel.
