No al bioetanol (II)
February 9th, 2008 Posted in Cooperación internacional, EE.UU., Economía, Europa, Medio ambiente
Hace unos dos meses expliqué en Netoratón por qué me opongo al bioetanol como sustituto de gasolina; en su comentario, Pablo Moreno Galbis apuntó a su post anterior reseñando que — además de reforzar los desequilibrios no sostenibles con países en vías de desarrollo como sostengo yo como argumento principal — además el bioetanol tiene un efecto neto negativo sobre el medio ambiente.
Ayer, Stephen Leahy escribió sobre dos recientes estudios que demuestran que el bioetanol causa un 93% más de emisiones nocivas que la gasolina.
Mientras la UE revisa su política de promover el bioetanol, aún hay quienes se empeñan en dejarnos ya no estancados, sino peor parados.
Bioetanol ¡no gracias!

Hola NV1962, here is my story on bioetanol en espanol.

Wow - I think it’s absolutely fantastic that you share your reports in English, French, Portuguese and Spanish; a highly commendable and in my opinion extremely helpful way to reach out and let independent, cogent and critical reviews based on sound research reverberate on the many critical issues that we face on a global scale.
Getting back to this topic, it’s beyond me how, for one example, the obvious links with agrobusinesses are so often overlooked, particularly in the USA albeit also within the EU, and in spite of the troubling and just as obvious implications for an honest assessment of how to confront and meet our energy needs responsibly and sustainably, given the fast evolving and enormously rapidly growing global economy.
Another topic that I might broach, although on the non-vehicular energy front, is the surprising and staggeringly vast potential for geothermal energy - which unlike solar and wind energy is a steady, predictable and continuous source, over an increasing period of decennia for newly tapped wells. Technology has made enormous strides to make it a far more affordable, profitable and in short attractive major supplement, ironically thanks in no small part also to advancing research and technology used in the fossile fuel extraction industry. Within the US, there’s not just an enormous potential, but a very promising pool of know-how and resources available (e.g. through the Geothermal Resources Council, see that earlier link).
But there’s still that pesky problem of a massive and ever growing global fleet of vehicles — I shudder thinking of the nearby future in China and India — and as such at least in the short term I believe the urgent pursuit of conservation strategies (i.e., mandating much, much more ambitious fuel efficiency standards) is a necessary first, albeit in the end insufficient step in the right direction. Substitution of problems with bigger ones clearly is not a feasible avenue, no matter how much corporate interests get in the way of doing right by our (grand)children.
So, in short: thank you for your help and efforts in making that understood to a wider audience. Muchas gracias por su visita, es todo un honor.
