* DALY—the number of years spent in the disease or lost at all, PDF-m\({}^{2}\)/a—potentially lost part of plant species, PAF-m\({}^{2}\)/a—a potentially damaged part of these species, MJ surplus energy—additional energy needed for future use of substitutes, inferior quality, sources of material or energy supply.

Table 1: Results of characterization of the environmental effects that occur in life cycles of land-based and offshore wind farms. Authors’ own research. substances (879,423.9 PAF-m\({}^{2}\)/a--land-based wind farm, 1,320,083.6 PAF-m\({}^{2}\)/a--offshore wind farm) were found to be the most harmful to the environment. In turn, fossil fuel extraction processes (2,437,145.9 MJ)--land wind farm, 1,752,643.1--offshore wind farm) contributed to exhaustion of natural resources to the highest extent. In terms of nonecological impact, it w the offshore wind power plant that is characterized by higher levels of adverse effects on human health and the environment, whereas a land-based wind power plant is more harmful in respect to natural resource depletion (Table 1). Nonsozological impact is referred to as a summary negative impact on benefits and environmental costs for four categories: emission of radioactive elements, processes connected with land use, processes of minerals, and fossil fuel extraction. In this type of impact, it is the excessive exploitation of fossil fuels that causes the most negative impact (2,437,145.9 MJ)--land-based wind power plant, 1,752,643.1--offshore wind power plant). In this impact area, it is the land-based wind power plant which poses a bigger threat to the environment and natural resources depletion, whereas an offshore wind power plant is more harmful to the human health (Table 1). The second stage of LCA analysis was normalization of the characterization results and their grouping and weighing, according to the earlier accepted assumptions (particularly European environmental conditions). Among eight categories of the nonergonomic impact, the highest level of negative effects was found for the processes connected with fossil fuel extraction (58,004 Pt--land-based wind farm, 41,713 Pt--offshore wind farm) and for emission of inorganic compounds causing respiratory system diseases (31,528 Pt--land-based wind farm, 24,846 Pt--offshore wind farm).
