Abstract
The increase in energy consumption in the world, with the decreasing resources of conventional energy, is increasingly leading to campaigns aimed at limiting the acquisition of energy from non-renewable sources to intensify the use of alternative energy sources. The paper presents the possibilities of obtaining heat energy using a heat pump for heating purposes, ventilation and hot water preparation. Hot heat sources for the heat pump are discussed and their energy possibilities in relation to the geographical conditions of the territory of Poland. Variants of heat pump cooperation with renewable sources in the form of air, soil and water were adopted for analysis. Two cases of co-operation of the ground collector with the heat pump are also considered, in the form of vertical and horizontal wells of the heat exchanger type. Based on the known methodology of seasonal heat demand, the final and primary energy consumption was determined for each analyzed case together with auxiliary energy. Based on the calculations carried out, the final emission of carbon dioxide was determined for individual cases and they were compared with the emission that would be generated when producing heat using a gas boiler and heating network.

Industry produces most of the energy needed from minerals
Alternative primary energy sources are another way of acquiring energy and let them include hydropower and such renewable energy sources as the sun, wind, heat within the Earth, sea tides, high tides and outflows, and other sources of energy that can be obtained in renewable processes [3]
On the basis of the calculations presented, it can be seen that the highest final energy consumption in the heating season will be with the air-source heat pump, while the lowest end-use energy consumption with the heat pump with a well
Summary
Industry produces most of the energy needed from minerals These are the basic sources of energy. Mining costs are continuing to grow and the demand for minerals is growing, especially in developing countries. All this translates into an increase in the cost of energy produced from traditional sources. The high requirements for the reduction of carbon dioxide emissions causes many countries to decide to significantly increase the share of energy produced from alternative sources in their energy balance, whose production does not have carbon dioxide emissions [1,2]. Renewable sources constitute a minimal share in the global energy balance, regardless of the rapid increase in production [2]
