Energy and its consumption effects still remain a strategic factor in pursuing sustainable development objectives. In addition to the noticeable advantages connected with the development and upgrading of various products, energy consumption, through generating harmful gas emissions, also causes climate changes and acid rain as well as quality deterioration in health foods. This is the reason why the role of the process energy consumption (energy efficiency), translating into the product quality, is becoming really crucial. In Poland, GDP primal energy consumption is 2.7 higher than the EU-27 average and 3.2 times higher than the EU-15 average. Poland and most of the countries will not solve their problems connected with the improvement in life quality or the impact of the power industry on the environment without an increase in economic energy efficiency. However, an upturn in energy efficiency (energysaving) should not lead to a decrease in product quality. The objective of this paper is to present energy and the effects of its consumption as the strategic factors in pursuing sustainable development goals. (original abstract)
