The aim was to use a simple model as a basis for gathering and discussing some central points in the debate on the advantages and disadvantages of energy taxation in relation to, for example, Denmark`s economy. These points could be the negative effects on resource utilization that arise when renewable energy is indirectly subsidized via taxation on oil, and on the other hand the advantages of stability of prices and supply. The conclusions of the model are restricted by the preliminary conditions and therefore are not in any way surprising. The main goal was to survey the ``losses`` (non-optimal resource locating, or promotion of ``expensive`` renewable energy sources) and ``gains``(supply stability and more stable prices). The conditions are described and the model constructed, and then the problems, first for an oil importing economy and after this for a situation where the economy changes to comprise oil exporting (in other words a situation like the Danish one) are discussed. The actual development in oil prices and economy are then dealt with by setting up a simple test relating to the possible connections between oil price and economic development. (AB).
