#157 of 165 More studies showing ethanol bad for environment by gagrice Sep 23, 2007 (7:10 am)
This one from the UK.   A renewable energy source designed to reduce greenhouse gas emissions is contributing more to global warming than fossil fuels, a study suggests.   Measurements of emissions from the burning of biofuels derived from rapeseed and maize have been found to produce more greenhouse gas emissions than they save.   Maize for ethanol is the prime crop for biofuel in the US where production for the industry has recently overtaken the use of the plant as a food. In Europe the main crop is rapeseed, which accounts for 80 per cent of biofuel production.   Professor Smith told Chemistry World: “The significance of it is that the supposed benefits of biofuels are even more disputable than had been thought hitherto.”   It was accepted by the scientists that other factors, such as the use of fossil fuels to produce fertiliser, have yet to be fully analysed for their impact on overall figures. But they concluded that the biofuels “can contribute as much or more to global warming by N2 O emissions than cooling by fossil-fuel savings”   http://www.timesonline.co.uk/tol/news/uk/science/article2507851.ece

#159 of 165 Energy Bill Passes by pf_flyer HOST Dec 19, 2007 (6:21 am)
The energy bill passed the house and has been sent on to be signed. As always, the Devil In The Details factor remains. Replies to this message: jeffyscott (Dec 22, 2007 5:05 am)
#160 of 165 Sacrifice stinks sometimes! lol by blkbr0tha Dec 21, 2007 (9:12 am)
From all of the articles I have read on Ethanol- A LOT.. things appear to be healthy for the environment. Especially when using the cellulosic method. Unlike corn ethanol- there are plenty of renewable resources such as switchgrass, paper sludge, and other biomasses. However, I think there are some main questions to ask about the legislation in the long term - not just for our environment but for our Economic Health as consumers. What about vehicle prices? They are sure to sky rocket What about the price of Ethanol? (it is already close to the current price of gas) What about the BIG OLI companies? (Do you really think they are going to let good ole Mr Clampett take over?   Yes, there are benefits to the plan- but at the cost of WHOM? Sacrifice is a mutha...

Replying to: blkbr0tha (Dec 21, 2007 9:12 am) Yes, there are benefits to the plan- but at the cost of WHOM?   It looks to me like you already know the answer to that question. WE are going to pay for any energy plan the FEDS concoct. And pay dearly.

Replying to: pf_flyer (Dec 19, 2007 6:21 am) The question I have about corn ethanol subsidies is - are the subsidies helping or hindering the development of cellulosic ethanol?   I could see it helping in that a market and distrubution system will, perhaps, be deveoped, but I could also see it hindering as the subsidies make taking the safe path of producing corn ethanol profitable, thus reducing the incentive to take the risk of investing in development of cellulosic.
#164 of 165 GREEN ALTERNATIVE FUELS by galvang May 29, 2008 (9:00 pm)
Some very interesting recent news regarding new fuels that are soon to be introduced. Now I do not know what type of volume they will produce however it is a good start.   The first starts with the "First Cellulosic Ethanol Demonstration-Scale Plant". Perfect for those anti-corn ethanol haters.   http://ir.verenium.com/phoenix.zhtml?c=81345&p=irol-newsArticle&ID=1151140&highl- - ight=   Second is 91 octane gasoline made from algae. They can produce it at $1.35 a gallon. Talk about green.   http://www.sapphireenergy.com/mediacenter/press_release/1   Again all these anouncements are a good start but in order for them to make a significant contribution to the energy sector it would have to build huge facilities to support this countries needs.
