Even when oilseeds (esterified, partially refined or crude) are used as diesel fuel extenders, the economic difficulty still persists and will continue until such time as diesel oil supplies begin to dwindle or until a more appropriate substitute fuel (renewable or nonrenewable) should emerge. Should diesel fuel supplies run out and an appropriate substitute fuel fail to emerge, tractors and other engine-driven equipment could convert to spark-ignition engines. These are more versatile in terms of fuel use (e.g. renewable alcohol, as well as nonrenewable hydrocarbons) even if less suited to the heavy workloads in agriculture.
Clearly additional investment in research and development is required to render the autonomous power supply options as economic and user-friendly as possible. Also, it should be noted that the purchased electricity supply, although not autonomous, could still be (at least in part) generated from renewable power sources. From a national perspective, renewable alternatives to diesel fuel for mobile equipment (e.g. oilseed fuels) (see also, Energy Sources: Renewable and Non Renewable) may also be considered as autonomous power.
