I see a number of people in this thread include biodiesel and wood burning with other renewable energy sources. While in theory biodiesel and wood burning are carbon neutral, the way they are used in Europe is anything but!
I wanted to warn you all that many countries in the EU currently enforce renewable resource quotas. This is what you want, however the incentives are incorrect, and the quotas are met by importing the wood/diesel from somewhere else. The EU does not oversee the reforestation/replanting of the combustible matter that is burned. So there's no guarantee that the wood/biodiesel consumed is actually carbon neutral. For all I know we're burning forests down but not planting them back. Not to mention that the biodiesel is competing with human food...
