[Digestion] Bio methane economy?

[Cezar T]

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
