Abstract
Basing on the first and second law of thermodynamics the fundamental
trends in the Polish energy policy are analysed, including the aspects of
environmental protection. The thermodynamical improvement of real
processes (reduction of exergy losses) is the main way leading to an
improvement of the effectivity of energy consumption. If the exergy loss
is economically not justified, we have to do with an error from the
viewpoint of the second law analysis. The paper contains a thermodynamical
analysis of the ratio of final and primary energy, as well as the analysis
of the thermo-ecological cost and index of sustainable development
concerning primary energy. Analyses of thermo-ecological costs concerning
electricity and centralized heat production have been also carried out.
The effect of increasing the share of high-efficiency cogeneration has
been analyzed, too. Attention has been paid to an improved efficiency of
the transmission and distribution of electricity, which is of special
importance from the viewpoint of the second law analysis. The improvement
of the energy effectivity in industry was analyzed on the example of
physical recuperation, being of special importance from the point of view
of exergy analysis.
