Oyuki, I was taking the piss just a little but the problem with bio fuels does underline one of the issues I have with the global warming movement and that is its shallow popularism. So we get people and companies trumpeting their green credentials through the use of bio fuels or other superficial actions when all they are doing is swapping one problem for another. I also love the conumdrum the green movement faces when it tries to rationalise its objection to nuclear energy with the need to find practical alternatives to fosil fuel.
If thats how you see it, then i suppose it does look ridiculous.
However, i have never read anything but criticism from environmentalists for biofuel, well before it was popularized . If your problem with global warming is due to short-sighted responses to it, then attack the green-washers and people trying to make a quick buck off the hoopla.
Most serious environmentalists are trying to find ways to make 'sustainability' a workable solution, not a branding scheme. Some have looked at nuclear power seriously, like Lovelock. However, i just see it as switching problems again.
There are lots of solutions out there, and like i said, no one is a silver bullet by itself. Another problem is that they cannot be controlled easily by large companies who wish to make a profit and control markets. They are by and large small-scale, and especially in the energy-generation sector, have possibilites to be democratized and local.
Look at Greenpeace's energy plan for the UK. Its pretty impressive.
