“…An exemplary emission factor for electricity generated in a gas power plant is 400 kg CO 2 /MWh, while for a coal power plant, it is 850 kg CO 2 / MWh [59]. Forecasts for the development of the energy sector in the 2060 perspective are varied (Olczak et al, 2020a;PARP, 2020). Depending on the variant, depending on the costs of emission allowances, gas prices, or the share of renewable energy, the share of coal energy in 2020-2040 changes from 62-56% for the variant with high costs of emission allowances from 51-14% with the possibility of reducing the emission level to 85 million Mg CO 2 .…”

Background: The growing consumption is what drives the development of unsustainable energy and material-intensive production technologies that emit large quantities of pollutants into the atmosphere, water, and land. Obtaining green energy allows reduction of the interference with the environment and, consequently, fits into a sustainable energy development strategy. In order to achieve the emission targets set by the EU for Poland, it is necessary to prioritize the development of renewable energy sources (RES) technologies within the energy sector.Methods: The purpose of the study was to present the results of the research relating to the return on investment of solar collectors for single-family houses in Poland. The research was presented on the basis of the legal conditions applicable to micro installations in the light of the amendment of the RES Act, and the impact of these amendments on the aspects of such investment was determined.Results: On the basis of the constructed economic model used to assess the return on investment of increasing the area of solar collectors, it has been shown that an operating installation will bring measurable economic benefits in the form of reduction in the amount of energy purchased annually in the amount of 6,756 kWh and environmental benefits in the form of reduction of carbon dioxide emissions to the atmosphere 2.4–3.6 Mg per year. An installation subsidized under the “My Electricity” program can reach an NPV of EUR 6,000 over 20 years at a discount rate r = 0 and assuming that the electricity is EUR 0.15/kWh. If the price rises to 0.2 EUR/kWh, the NPV will be 10,000 EUR. For the analyzed installation, the investment consisting in increasing the collector area in accordance with NPV is economically effective for the absorber area in the range of 5.6–7.6 m2 and reaches the maximum value for the absorber area of 6.6 m2, while the absorber area above 7 m2 contributes to reduce the value of the economic return on investment. The obtained results have been generalized, which allows to use them in the process of selecting the size of collector area for similar installations.Conclusion: The return on investment analysis carried out in respect of a detached house allowed to demonstrate that this project is fully justified. Furthermore, pursuant to the Renewable Energy Sources Act in force in Poland, treating a small entrepreneur as a prosumer who may generally take advantage of favorable conditions for discounting the produced energy leads to very favorable possibilities of settling electricity. Considering an entrepreneur as a prosumer who may use one-off depreciation of a solar collectors installation as a fixed asset and request for VAT refund is what makes such an investment very attractive in financial terms and makes it difficult to find a safe investment alternative characterized by such a high rate of return.

“…At the same time, most of the scientific works on similar topics concern countries in which the development of energy generation using photovoltaic cells is significant -mainly China, and in Europe, Germany or the Czech Republic (Roos (2021), in Poland, e.g., rural areas (Piwowar and Dzikuć, 2019), or the western part of the country. There are also studies presented in a similar approach, but calculated for an individual object Olczak et al, (2020). On the other hand, there are no scientific studies comprehensively covering the area of the Małopolskie Voivodeship in relation to the possibility of obtaining an ecological effect with the use of photovoltaic installations.…”

Renewable Energy Sources vs. an Air Quality Improvement in Urbanized Areas - the Metropolitan Area of Kraków Case

The premise for the selection of the topic discussed in this article is the lack of research on the level of reduction of air pollutant emissions by the use of photovoltaic micro-installations in single-family buildings, both in Poland and other countries of Central and Eastern Europe. Therefore, the Authors made an attempt to estimate the scale of air pollution reduction (in particular CO2) in the area of the urbanized Metropolitan area of Krakow, which is one of the most polluted regions in Poland. The installation of photovoltaic panels on single-family buildings, co-financed by the government My Electricity Program, is the investment cost in improving the air quality in this region, and thus increasing the well-being of its inhabitants.

“…The interest in renewable energy sources is also related to caring for the environment and searching for long-term potential actions for sustainable development (Lin and Ren 2020;Østergaard et al 2020;Canales et al 2020). One of the important renewable energy technologies is photovoltaics (Allied Market Research 2019;Olczak et al 2020a). The pace and nature of its expansion around the world vary, including across the EU.…”

In less than a decade, the photovoltaic sector has transformed into a global business. The dynamics of its development vary depending on the country. According to estimates, the value of the photovoltaic micro-installations market in Poland at the end of 2019 exceeded PLN 2.8 billion. In the first half of 2020, the PV sector recorded dynamic growth with a total capacity of the micro-installations of 2.5 GWp. Government subsidies were among the factors contributing to the expansion of the PV sector. In Poland, there are many financial ways to intensify the construction of new renewable energy source installations, among others: feed-in tariff, grants, and loans. An example of photovoltaic grant support in Poland is the "Mój Prąd" [My Electricity] program created in 2019 with a budget of PLN 1.1 billion. The interest in the "My Electricity" program in individual provinces may vary, depending on socio-economic factors, technological and environmental resources, and the level of innovation. The research motivation of this article is a comparison of provinces in Poland according to selected energy, environmental, innovation, and socio-economic indicators and to show how these factors affect individual interest in the "My Electricity" photovoltaic development program in provinces. The highest correlation is for the total installation power under the "My Electricity" program and Gross Domestic Product and Human Developed Index. The highest correlation coefficient from RIS indicators and photovoltaic data programs was achieved for "R&D expenditure in the business sector". The population was closely correlated with the total installation power and the grant value of the "My Electricity" program.
