I have found very consistently that people who think bio gas is the solution to all kinds of stuff have never actually worked on bio gas systems and just read about it on the Internet.
A lot of industrial users who can make bio gas already are.
Where I work we produce over 100 million BTU per day and use it all.
To break that down an average home uses maybe 1 million BTU the heat water, cook food and use a gas dryer in warmer weather.
Over a real cold winter a home might use 10 to 25 million BTU per month.
Total natural gas use where i work per day is over 1 billion BTU.
Every little bit helps and it is only a little bit.
Then there is the electrical. We use something like 400 mega watt hours per day.
This is just one factory and it runs 24/7 about 360 days a year.
I understand some what it would take to replace fossil fuel since I have been formally educated on the wind, sun and diesel power generation and I do lots of power calculations, that's mostly what engineers do. Power, heat and mass transfer, some vibrations.
