Abstract
"The article considers two options for autonomous power supply using both traditional and non-traditional fuels. The efficiency of using renewable energy sources is described depending on the climate, geographical location and method of energy production. The relevance of this topic is caused by increasingly high environmental requirements for production. Moreover, decentralization with the use of unconventional sources allows the energy system to be more flexible in an autonomous mode, taking into account the time of day, the intensity of solar, wind and hydropower. The use of renewable energy sources is also possible in combination with solid, liquid and gaseous fuels. Combined systems are very convenient for power supply of small objects. These can be settlements remote from centralized power supply, autonomous industrial facilities, peasant farms, livestock farms. One of the energy supply options is more suitable for the northern region of the country with a long cold period and the presence of large coal reserves, there is an opportunity for the consumer to receive gas, as well as heat and electric energy when using coal as a feedstock, a kind of local gas network. The second method will ensure the disposal of animal waste and organic waste. Keywords: alternative energy sources, biogas, gaseous fuel, coal processing, autonomous power supply."
