Alternative Energy Sources

Alternative energy sources, mostly related to “green” energy, are one of the promising trends in the development of energy generation, including for the global railway sector. This is due, firstly, to its desire to preserve its environmental advantages by reducing carbon dioxide emissions into the environment and increasing energy efficiency, and secondly, to a reduction in the use of such sources as oil and coal as fuel resources in the coming decades.In a world where 95 % of motorized vehicles use oil as fuel, the greenhouse gas emissions per passenger-kilometer for rail transport are five times less than for road transport and 20 times less than for air transport. Therefore, one of the key tasks in the development of railway transport is the creation of high-speed highways that will serve as an alternative to road and air communications over short distances.In addition to the well-known alternative energy technologies, the railway transport traditionally conducts scientific research to improve energy-saving technologies, which include the use of excess recuperation energy when rolling stock braking.Also, projects for the use of renewable energy sources — heat pump installations — have proved their effectiveness in railway transport: heating switches from the ground, use of heat from compressors of hill complexes to heat electrical centralization posts and heat transformers of traction substations for its own needs.The role of alternative energy sources in railway transport is constantly growing. The efficiency of using alternative energy sources at the Russian Railways is largely determined by a scientific approach that allows, based on own experience or experience in introducing innovations in related industries, to determine the place, time and degree of their implementation, taking into account technical and technological features of production processes inherent in a particular structural unit companies. Among the innovative technical solutions in railway transport, the most priority ones are solutions aimed at the development of high-speed lines, recuperation systems, as well as heat pump technologies.

The Cost

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.
