| Abstrakt | In recent decades considerable attention has been paid to alternative and renewable energy. Among the alternative sources, the sun’s energy is most appealing. Therefore, the development of solar energy, in the long run, is one of the top priorities. In practice, there are numerous barriers to the growth of the solar energy market. First of all, economic: fairly high prices for solar systems and payback period; the absence of working capital from manufacturing enterprises, the absence of specific mechanisms for stimulating production in the form of subsidies, tax exemptions, preferential tariff policies, etc. Therefore, research into the development of solar energy, as a real tool for a comprehensive solution to economic and environmental problems, is becoming increasingly relevant. The paper considers the energy policy of the use of renewable energy sources in rural areas. The theoretically feasible and technically achievable potential of solar energy in the territory of Ukraine was characterized. It was noted that the sun is the most affordable supplier of energy on earth today. The use of solar radiation is expedient for the development of thermal and electric energy and is possible throughout the territory of Ukraine. The dynamics of the commissioning of solar power plants by private households was analysed. The attention is focused on the application of the ‘green’ tariff, which stimulates the increase in the number of solar projects implemented in households. A financial model of private households of choosing a solar power plant option was proposed. The problems were identified and the possibilities of using solar energy for ensuring energy independence of households and profit generation were assessed. The forecast for the development of solar energy of the period up to 2020 was made. |

| Title | POTATOES AS A POTENTIAL SUBSTRATE FOR A BIOGAS POWER PLANT |
| Słowa kluczowe | biogaz, energia elektryczna, fermentacja metanowa, ziemniak |
| Key words | biogas, electric energy, methane fermentation, potato |
| Abstrakt | Ziemniak jest zaliczany do surowców roślinnych mających wszechstronne zastosowanie, począwszy od branży spożywczej, aż do wykorzystania przy produkcji pasz. Klasyfikuje się go zarówno do roślin jadalnych, pastewnych, jak i przemysłowych. Odpady z przetwórstwa ziemniaków można wykorzystać do celów energetycznych, m.in. do wytwarzania paliw ciekłych czy skojarzonej produkcji energii elektrycznej i cieplnej z biogazu powstałego w wyniku fermentacji metanowej. Badania wydajności biogazowej dla czterech prób substratów przeprowadzono zgodnie z obowiązującą niemiecką normą DIN 38 414/S8 w Pracowni Ekotechnologii na Uniwersytecie Przyrodniczym w Poznaniu. |
| Abstract | Potato (Solanum tuberosum) is a very versatile vegetable, largely used as food for human, animal feeding and as well classified as industrial plant. Waste from processing potatoes can be used for energy purposes such as: liquid fuels or a combined production of electricity and heat from biogas production by anaerobic digestion. In order to test the biogas potential of potato waste an experiment were conducted at the laboratory of Eco technology of the Poznan University of Life Sciences. The treatments: I – control, II raw potatoes, III – steamed potatoes, IV – raw potato skins, V – steamed potato skins were tested in accordance to the German normalization DIN 38 414 / S8. Additionally, economic aspects concerning the revenue obtained from the sale of electric energy produced according to biogas yields observed in laboratory were estimated. |
