[Biofuel] 12% renewable energie in electrical production

[Fritz]

Hello Keith,
as always you are able to put my thougths in better words,but than,thats 
what journalists du best!
My poor english does not help either
but at least there are some idias on the table andto say it bothered me 
always to see so much waste not put to good use!
By the way,my TDI runs beautiful on BD
All the Best
Fritz

[Biofuel] 12% renewable energie in electrical production by 2025

[Fritz]

When i read your post,it seems to me that Biomass is wether woodchips 
or  sweetgrass  or
how about putting thins together and combine all of it.Including Manure 
and  humanwast !
The 8% agricultural could be replaced by wood or other forest dropings

Hello Fritz

>or  sweetgrass  or

You mean switchgrass? It's much touted for so-called 
second-generation biofuels production (fuel for transport), but 
that's just pie in the sky (like oil from algae). I suppose it'll 
burn though.

But that brings us back to the "How much land?" question. Have you 
read the link I referred to?
"How much fuel can we grow? How much land will it take?"


>how about putting thins together and combine all of it.Including Manure
>and  humanwast !

Human waste is the only kind there is, all waste is human, nature 
never wastes anything. That's relevant in a discussion about energy, 
since most energy used in the US is wasted. I also reffed a quote by 
Lovins, saying that the biggest gains are to be made in improving 
energy efficiency.

But you mean sewage eh? "Humanure". It's a good point - do wastewater 
treatment plants produce excess methane that could be used for power 
generation?

Something like half the food supply is also wasted, and most of that 
probably ends up in landfills. There are projects that are harvesting 
methane from landfills. Is there any opportunity for that in Adams 
County? And if so, even if it were optimised for energy production, 
wouldn't it make for an even more favourable energy equation if all 
that food weren't wasted in the first place?

I agree with you about putting it all together, especially at the 
household level, and much more is possible than just persuading 
consumers to switch to compact fluorescents. A lot of people, for 
quite a long time now, but especially recently, are questioning the 
whole basis of consumerism itself, and whether they really want to be 
a part of it, and deciding that they don't want to be a part of it, 
and don't need to be, there are alternatives. That can and will 
change the whole nature of the marketplace, and to my mind at least, 
that's the best way to cut energy use. The greater the efficiency and 
the lower the demand, the easier the conversion to biofuels/biomass 
will be.

Best

Keith

It's all hype Jim. It just doesn't exist yet. See:

Sorry about that.

couldn't agree w/you more, keith.  you reffed a quote earlier fron the
rocky mtn inst, about efficiencies being the fossil fuel savings in
recent decades, and that mostly those efficiencies didn't require
behavioral changes.  this is precisely the problem.

Yes, a contstrained solution. But people are prepared to make 
behavioural changes now, IMHO. So much the better. With a little help 
from the empowerers that be, surely much can be achieved. Not much I 
can do about it though, from the other side of the world, so I 
brought it here.

All best

hi, keith.  sorry if my last post had a "negative nelly" tone.  didn't
mean for it to sound that way, but didn't have the time to consider
composition.  well, not now either.  not even in bed yet and i have to
start all over again in 4 and a half hrs!  anyway, i hope you're right
about ppl being ready.  doesn't really matter, though.  like the
saying goes from hide and seek, "ready or not, here i come!"

I didn't think it was negative Chris. Four and a half hours isn't 
enough - but I know the feeling! I hope you get some rest soon. Take 
care - all best, Keith
