Ever more power is what we must have to continue our current way of life cf. Footnote 5 . Iogen s plant delivers the power of 7 barrels of oil per day 68 kW . Average power of petroleum wells in the largely oil-depleted US was 10 bbl well-day -1 in 200612 98 kW . Therefore an average US petroleum well delivers more power than a city-block size Iogen facility in Ottawa and its area of straw collection probably 50 km in radius which at this time is saturated with fossil fuels outright and their products ammonia fertilizers field chemicals roads etc. . The petroleum well also uses little input power unfortunately soon petroleum will not be a transportation option. Such is the difference between solar energy stocks depletable fossil fuels and flows daily photosynthesis . One can calculate that an average agricultural worker in the US uses 800 kW of fossil energy inputs and outputs 3 000 kW. An average oil gas worker in California uses 2 800 kW of fossil energy inputs and outputs 14 500 kW. Due to fossil energy and machines these two workers are supermen each capable of doing the work of 8 000 and 28 000 ordinary humans respectively. These two fellows are about to become human again and we need to get used to this idea. Now you may want to go back to Section and rcread it. Where will the Agrofuel Biomass Come from Collectively the EU and the US have spent billions of dollars to be able to construct the inefficient behemoth factories which in the distant future might ingest megatonnes or gigatonnes of apparently free biomass trash and spit out priceless liquid transportation fuels. It is therefore prudent to ask the following question Call out using the new paragraph and gray background. The answer to this question is immediate and unequivocal Nowhere close to .
