In recent times, agriculture has become a major fossil fuel energy user.
The impression given is that fossil fuel use will continue to rise, and that coal is the fuel of the future.
Our calculations indicate that rotation and no-till systems use substantially less fossil fuel in comparison to conventional systems.
For each farm type (conventional, rotation and no-till) we estimated average yearly fossil fuel energy use.
As fossil fuel reserves diminish, alternative renewable sources of energy will be needed to sustain economic growth.
Our model of baseline fossil fuel consumption allows autonomous energy efficiency improvements.
The model's dynamics derive from fossil fuel depletion, productive capital accumulation, and the putty/semi-putty specification of technology.
This however will be weighed against the effect of more expensive fossil fuels, as a result of the fossil fuel tax.
