Abstrakt | In the world renewable energy sector, including large hydropower, employed 10.3 million people, directly and indirectly, in 2017. This represents an increase of 5.3% over the number reported the previous year. The aim of the executed research is to determine the influence of harvesting renewable energy on the labour market in EU. Eurostat databases provided a source of empirical data concerning the amount of produced energy. The following sectors were considered: solid biofuels, biogas, liquid biofuels, geothermal, hydropower, municipal waste, solar photovoltaic, solar thermal, wind power and heat pumps. The research concerned 28 Member States of the EU between 2009 and 2016. Panel estimation was used as means of empirical indication of relations between the variables. The obtained models are adjusted to the empirical data, the rectified coefficient of determination equalled, depending on the sector, 0.828 (liquid biofuels) to 0.981 (solid biofuels). The analysed models show that throughout the examined period, the solar and wind power sectors were the ones that consumed the larger amount of work. As it was indicated above, these sectors are considered the most innovative and technologically advanced ones and thus, the employment rates seem to decreased in the shorter time. |

Title | Sustainable Development and Renewable Energy Sectors: Selected Indicators in European Union and Poland |
Słowa kluczowe | sustainable development, renewable energy, UE, Poland |
Key words | sustainable development, renewable energy, UE, Poland |
Abstrakt | The aim of this article was to show the position of Poland in the renewable energy subsectors among the European Union countries. The research covered the areas of biomass, solar heating and heat pumps, showing the degree of their utilization, power required to drive the system and their production in 2016. The provided information was supplemented with a revenues per employee in thousand euros in chosen subsectors of renewable energy sources in the year 2016. The main tool for carrying out the set objective was the use of descriptive and comparative methods. The results of the survey demonstrated Poland’s prominent place in the sector of liquid biofuels (1st place in EU), thanks to the significant supply of raw materials as well as development perspectives in solar energy, which is confirmed by the world's statistics indicating a record number of photovoltaic installations fitted (PV). |

Abstract | Average full (including capital, operation and maintenance costs) annual heating costs in a standard family house with 180 m2 of floor surface are compared for various heating systems under the Polish economic conditions. The compared heating technologies comprise water to water and ground loop heat pumps with both vertical and horizontal loops, a liquid gas combustion furnace, an earth gas combustion furnace, a coal combustion furnace, a straw combustion furnace, a wood combustion furnace and an electric stove. A sensitivity analysis with regard to the interest rate and the value of owner’s work did not change the general conclusion that in most cases heat pumps were the cheapest, while oil and coal burning furnaces or an electric boiler the most expensive solutions. The cost of own labour was decisive for the appraisal of labour intensive systems |
