I have heard that in Sweeden there are even busses that use water instead of fuel… We should try to give up the fuels that pollutes the atmosphere and use the ones that don't.inchirieri apartamente clujhttp://www.edil.ro/noreply@blogger.comtag:blogger.com,1999:blog-25163458.post-45582476181827498772008-02-13T19:04:00.000-05:002008-02-13T19:04:00.000-05:00True, biofuels are not inherently evil.

If production does not require clearing forests or grasslands -- either using degraded lands or reducing other crop uses (like animal feed) -- some of the existing and many of the proposed (jastropha) might make sense.Simon Donnerhttps://www.blogger.com/profile/01844831377442275615noreply@blogger.comtag:blogger.com,1999:blog-25163458.post-87214288523167092192008-02-13T13:22:00.000-05:002008-02-13T13:22:00.000-05:00These studies do seem to be extremely valuable, an...These studies do seem to be extremely valuable, and the land-use cascade idea very useful. Investing in demand reduction, and setting higher efficiency standards look all the more the first best way to go, for transport fuels as for other kinds of energy use.
