摘要：The energy perspective of the near future relies on the use of natural gas and renewable energy resources and for the distant future hydrogen energy is shaping up. In order to provide the correct information necessary for a high-performance option in the case of the availability of photovoltaic panels or cogeneration generators, this paper addresses energy performance and environmental impact in the case of the two systems based on different primary energy resources. The comparison method is based on the calculation of energy balance elements and the results obtained are used to calculate quantitative and qualitative performance indicators. Based on the obtained indicators, the level of response to the requirements of a sustainable energy is verified, for the analyzed variants.
