Pro-ecological exergy tax

Wojciech STANEK, Silesian University of Technology, Poland

The concept of the pro-ecological tax or support is presented. It could replace the existing subsidy mechanisms for renewable power technology or could represent the ecological taxes burdening the fabrication of consumer products based on nonrenewable resources, e.g., electricity from the conventional fossil fuel power plants. Moreover, the proposed concept for renewable power technologies could represent a new system of subsidy based on physical laws. The proposed pro-ecological tax or suport is defined as proportional to the thermo-ecological cost (TEC). TEC proposed by prof. Jan Szargut expresses the cumulative consumption of nonrenewable exergy burdening the fabrication of the considered consumption of the product with the additional inclusion of necessity of compensating adverse environmental effects due to harmful waste products rejection. It is assumed that calculating new exergy tax or subsidy for electricity, the total cost burdening the final consumer remains the same. This principle determines the coefficient of proportionality between the cumulative consumption of nonrenewable exergy (TEC) and the value of the tax or subsidy. The higher is the efficiency of power technology, and the lower is the TEC of fuel, the lower tax is provided in the case of non-renewable systems. In this presentation the example results of TAX calculation using the proposed exergetic method are presented.
