 abstract={The interpretation of geothermal conditions in SW Poland presented here is based on temperature logs from 80 boreholes, acquired under steady-state conditions at depths exceeding 500 m. The recent and archived drillhole data is also considered. The wells penetrate several tectonic units, including the Sudetes and their foreland, the Fore-Sudetic Monocline and the Opole Basin, each representing a different lithology and structure. Our interpretations offer the spatial temperature distribution over the study area, depending on the depth and height coordinates of the measurements. Average temperature values were observed to increase from 22.8°C at a depth of 500 m, to 63.4°C at a depth of 2.5 km. The highest temperature of 97.7°C was measured at a depth of 1,870 m in the Jelenia Góra-Cieplice C-1 well. Average temperatures at various elevations increase from 16.5°C (0 m a.s.l.) to 61.5°C (–2,000 m a.s.l.). Over the Sudetic Block, higher temperatures can be achieved at the same elevations, while greater depths are required to reach these temperatures in other tectonic units. The results are crucial to planning investments aimed at sustainable management of geothermal resources. They facilitate the identification of locations for new thermal water intakes and thus new sources of renewable energy. The knowledge of thermal conditions of the area makes it possible to plan optimal use of water and geothermal energy in various sectors of the economy (heating, agriculture, recreation, balneotherapy) thus boosting economic development of the region, increasing energy efficiency and limiting negative environmental impact.},
