To both of your points I'd say the major difficulty is in separating out a fully ethanol/re-newable energy supply system from one that produces ethanol, but uses non-renewable energy for production. For example, it's very conceivable that combinations of ethanol, solar, wind, and other renewable energy sources can be the only energy used in ethanol creation. In that case, even if you use more energy than ethanol contains, it doesn't matter because you're not using fossil fuels. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Message: http://www.houseoffusion.com/lists.cfm/link=i:5:208758 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/5 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:5 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.5 Donations & Support: http://www.houseoffusion.com/tiny.cfm/54
