Summary & screenshots of Ntl Geographic's interactive module for comparing biofuel sources. Will it be corn, sugarcane, scum (algae) or nought? Ladies & gentlemen, place your bets!

Corn will drive up cost of food, etc. There's got to be something better.

It also shows comparison of each source’s greenhouse gas emissions and energy balance (ratio of the amount of fossil fuel required to make each biofuel to the amount of energy the biofuel itself can produce).  Naturally, it uses gasoline cost and output as benchmarks.  Concise audio commentary provided on each source rounds out the snapshot analysis.</P></blockquote><div style="border-bottom: solid 1px #dcdcdc; white-space: nowrap; margin-bottom: 8px; background-color: #eeeeee ;background-image: url(http://clipmarks.com/images/source-bg.gif); background-repeat: repeat-x; height: 24px; line-height: 24px; vertical-align: middle; padding-bottom: 4px; color: #666666; font-size: 10px;" ><a href="http://clipmarks.com/clip-to-blog/" title="see clips that are hot right now"><img src="http://content8.clipmarks.com/images/clip-icon.gif" alt="" width="19" height="19" border="0" style="vertical-align: middle; margin: 0px 4px; display: inline; border: none; float:none;" /></a>clipped from <a title="http://akuse.com/Blog/blog_pics/tech/BioFuel2.png" href="http://akuse.com/Blog/blog_pics/tech/BioFuel2.png" style="font-size: 11px;">akuse.com</a></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://akuse.com/Blog/blog_pics/tech/BioFuel2.png"><div align="center"><img src="http://content9.clipmarks.com/blog_cache/akuse.com/img/AC27BE4C-F2FF-41C0-8FB5-B6E27E03F39F" alt="The image “http://akuse.com/Blog/blog_pics/tech/BioFuel2.png” cannot be displayed, because it contains errors." /></div></blockquote><div style="border-bottom: solid 1px #dcdcdc; white-space: nowrap; margin-bottom: 8px; background-color: #eeeeee ;background-image: url(http://clipmarks.com/images/source-bg.gif); background-repeat: repeat-x; height: 24px; line-height: 24px; vertical-align: middle; padding-bottom: 4px; color: #666666; font-size: 10px;" ><a href="http://clipmarks.com/clip-to-blog/" title="see clips that are hot right now"><img src="http://content6.clipmarks.com/images/clip-icon.gif" alt="" width="19" height="19" border="0" style="vertical-align: middle; margin: 0px 4px; display: inline; border: none; float:none;" /></a>clipped from <a title="http://akuse.com/Blog/blog_pics/tech/BioFuel3.png" href="http://akuse.com/Blog/blog_pics/tech/BioFuel3.png" style="font-size: 11px;">akuse.com</a></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://akuse.com/Blog/blog_pics/tech/BioFuel3.png"><div align="center"><img src="http://content7.clipmarks.com/blog_cache/akuse.com/img/9EFD241D-6645-4F47-8FC4-BD965CEB8502" alt="http://akuse.com/Blog/blog_pics/tech/BioFuel3.png" /></div></blockquote><div style="border-bottom: solid 1px #dcdcdc; white-space: nowrap; margin-bottom: 8px; background-color: #eeeeee ;background-image: url(http://clipmarks.com/images/source-bg.gif); background-repeat: repeat-x; height: 24px; line-height: 24px; vertical-align: middle; padding-bottom: 4px; color: #666666; font-size: 10px;" ><a href="http://clipmarks.com/clip-to-blog/" title="see clips that are hot right now"><img src="http://content8.clipmarks.com/images/clip-icon.gif" alt="" width="19" height="19" border="0" style="vertical-align: middle; margin: 0px 4px; display: inline; border: none; float:none;" /></a>clipped from <a title="http://akuse.com/Blog/biofuels-compared/" href="http://akuse.com/Blog/biofuels-compared/" style="font-size: 11px;">akuse.com</a></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://akuse.com/Blog/biofuels-compared/">every biofuel consumes crops that could be used for food (UN says 25,000 people die of hunger every day, most under age five).   However, non-food source of ethanol (eg grass as opposed to sugarcane) is currently just 45% efficient (amount of energy extractable per unit) compared to 85% for crude oil.  Others see biofuels as a total waste that deters from what should be the real goal; conservation.</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://akuse.com/Blog/biofuels-compared/"><div align="center"><img src="http://content9.clipmarks.com/blog_cache/akuse.com/img/26409735-1289-4E6F-9319-9E9B20499F1C" alt="BioFuel4" /></div></blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/5B23DE2A-3D57-423F-B6B0-C220181042C7/blog/" title="blog or email this clip"><img src="http://content6.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
