“…Approved exploitable resources for the Uniejów PIG/AGH-2 well amount to 120 m 3 /h, the water temperature at the wellhead reaches 69.2 • C and the static pressure under artesian conditions amounts to 2.6 bar [31]. The water exhibits an elevated mineral content ranging from 6.8 to 8.6 g/L [32]. The total thickness of the sandstone series from which water is extracted in Uniejów is around 120-150 m. The effective porosity of the sandstone ranges from 12% to 20%.…”

The paper presents a review of the geological and hydrogeological data of the Lower Cretaceous aquifer in the Polish Lowlands and discusses the possibilities for the utilisation of geothermal water resources in existing and new district heating systems. Based on experience related to the use of thermal waters in existing geothermal systems, and using data from the literature, assessments have been made of the energy and environmental effects of the application of low-enthalpy geothermal resources from the Lower Cretaceous aquifer as a source of heat for urban district heating systems. The authors concluded that the implementation of such solutions could result in the production of approximately 4 PJ of geothermal energy annually. To date, these resources have only been developed in three locations—Mszczonów, Uniejów and Poddębice—with the total amount of energy generated annually reaching 100 TJ/year. Similar district heating networks in 120 nearby localities have been also identified. Here, specified geological and hydrogeological conditions enable the extraction of heat from the investigated Lower Cretaceous aquifer, with the aim of using this for heating purposes. To achieve this goal, multiple measures are required, including the following: raising public awareness through appropriate education programmes aimed at the youngest school children; systemic, efficient energy management measures at the central, regional and local levels, and providing financial support and ensuring regulations and laws aimed at improving the development of geothermal resources.

“…The fact that this resource is practically limitless and renewable, together within contrast to the solar option -its independence of changing climate and weather conditions, present clear advantages in favour of its enlarged utilization. Irrespective of the obvious climate protection benefits, the direct and indirect development of these resources for heating, agriculture and horticulture, should also respect other elements of the natural environment (Tomaszewska et al, 2016). Table 1.1 shows global installed thermal capacities, thermal energy utilization and capacity factors for different applications in agriculture and the agri-food chain using geothermal resources and their change from 1995 to 2015.…”

“…The desalination of geothermal waters used for energy purposes could be seen as a one of the methods of securing high-quality water for various purposes. In countries with warm climates it is mainly used for the irrigation of agricultural crops (Kabay et al 2004a(Kabay et al , 2004b(Kabay et al , 2009Koseoglu et al, 2010;Tomaszewska et al 2016). Given the increasing deficit of freshwater worldwide, the possibilities for desalinating and treating geothermal waters for drinking and household purposes should be considered (Gallup 2007;Bodzek, 2013a, 2013b;Gude 2016).…”

Energy audits are a crucial part of farm energy management (Chen and Baillie, 2009a). This type of audit refers to the systematic examination of a farm, facility or site, to determine whether, and to what extent, it has used energy efficiently. An energy review determines how efficiently it is being used. It also identifies energy cost saving opportunities and highlights potential improvements in productivity and quality. An energy check may also assess potential savings through strategies such as fuel switching, tariff negotiation and demand-side management (e.g., by changing to alternative farming systems and farm layouts). An energy assessment may be undertaken as part of a broader plan to manage production inputs on-farm (Chen and Baillie, 2009a). The objectives of energy audits include: • Conserve energy inputs. • Reduce greenhouse gas emissions. • Achieve operational and cost efficiencies with improved productivity and profitability. Extensive research has been conducted on both energy use and conservation in agriculture. Recent results of energy efficiency programs have shown considerable variation in energy use between different crops and also different farms of similar production systems (Chen et al., 2015). Pellizzi et al. (1988) found that in Europe, the range of field energy consumption for wheat-like cereals varied from 2.5 GJ/ha to 4.3 GJ/ha. For cotton, a study by Chen and Baillie (2009b) showed that the direct energy inputs for cotton production in Australia ranged from 3.7 to 15.2 GJ/ha. Diesel energy inputs ranged from 95 to 365 liters/ha, with most farms using between 120 to 180 liters/ha. Dryland cotton was at the lower end of this range. The direct on-farm energy use of some nursearies may be up to 20,000 GJ/ha (Chen et al., 2015).

“…Natural geothermal water, as the critical carrier of geothermal energy, has been widely exploited for physical therapy and power generation because it is extensively distributed and practically limitless as well as renewable [28] . The exploitation of geothermal water utilized for energy purposes is increasingly regarded as a valid method of dealing with the energy crisis and alleviating the pollution of environmental [29,30] .…”
