[Digestion] Bio methane economy?

[Paul Harris]

G'day All,
 
What we really need to work towards is an "Energy Economy", independent of
different technologies and arbitrary monetary values - a Joule is a Joule is
a Joule in USA, Europe, India or China and can be neither created or
destroyed (it is also a bit harder to "bank" than a
dollar/euro/yen/etc/etc).

Happy digesting,
HOOROO

Hi everyone,
I agree "hydrogen economy" is a losing proposal, but how much better is
biogas? How does its economy and energy balances comparing with other
biofuels, or other renewable energy resources?

There is a recent trend to blame food increase prices or  rainforest cuts
and even increased greenhouse gases upon the increased demand of "evil"
biofuels - like ethanol or biodiesel. Can biogas be considered more
food-crop friendly?

thanks,
cezar
