The use of alternative energy sources in the planning of ecotourism facilities as one of the technological methods of environmental protection
The article presents the results of research on environmental, energy and economic efficiency of the use of alternative energy sources to provide heat to buildings located on the territory of nature reserves. Spending of time on the territory of the nature reserve fund gives the chance of various kinds of rest: use of bicycle routes, ecological paths, the organized places of recreation, etc. Therefore, in specially designated areas complexes are built for vacationers. They provide them with a comfortable stay and the opportunity to get the most out of the chosen type of recreation. Electricity networks are most often used to provide buildings with electric power on the territory of nature reserve facilities. However, this has a significant negative impact on the environment. Many of these facilities are located at a great distance from the settlements, that increases the cost of electrification and gasification. Such facilities require large investments in hot water and heat. Therefore, alternative energy sources are suitable for such cases. The main advantage of using solar panels and heat pump is their environmental friendliness and long period of operation without major repairs. It is established that for the installation of vertical probes it is enough to use four branches 106 m long. For this combined system it is necessary to install six solar collectors, which will provide monthly heat production in the amount of 514.03 MJ. The use of solar collectors and a heat pump to provide heat to the visitor center will reduce the annual operating costs by 4.63 times compared to the costs required for the operation of a system that would operate on the basis of a gas boiler. The use of a combined heat supply system will make it possible to abandon the use of 7156.3 kg of conventional fuel and as a result will reduce carbon dioxide emissions in the amount of 7871.9 kg. Our country is interested in the use of renewable energy sources by reducing the cost of traditional energy sources, the overall reduction of greenhouse gas emissions during combustion. The state receives direct income from the sale of quotas for harmful emissions.
