but you appear to contradict yourself a bit with saying biofuels are a really bad idea but then say bio-gas, which is a type of biofuel, is a good idea under certain circumstances (which I agree with. And I would describe those circumstances as when biofuel is made from waste and used for most purposes other than fuel for most types of transportation other than aircraft)
To clarify, I am not against all biofuels. I am against developing biofuels or subsidizing them specifically for use in transport. There are a number of problems with doing that:
1. It typically uses productive land that could be put to better use.
2. It is often a scam whereby significant amounts of fossil fuels are used in the production process.
3. It continues to promote the internal combustion engine whose day has come and gone.
Its time for electric cars. (and soon after that, planes)
I accept that countries like Brazil with large biofuel production already in place should not discontinue it suddenly, but I do think that as electric cars replace fuel based cars they should gradually phase out biofuels.
Note that the article you originally linked pointed out that one of the drivers for biofuel production in the US is a desire to be energy independent. There are better ways to achieve this. The problem is the farm lobby in the US is extremely powerful as is the automotive industry lobby.
