Ethanol does not belong in the list. It is not efficient to make and it doesn’t have all that much energy in it.
burning food for energy is an act of desperation, not a “green” act.
The trouble is it takes more than subsidies to make these turkey’s fly. They also need mandates for use and import duties to make get investors to invest.
I noted that this website is encouraging a no vote on prop 23..in CA that is a real vote not just a poll and I have already voted yes on CA to at least partially block CA’s crazy drive into alternative energy that doesn’t pay.
