Abstract: The dynamics of total consumption of electric and thermal energy in agriculture and in the whole country is considered in the study. The analysis of developments in the field of solar and bioenergetics their current state and possible directions of research on the use of RES in livestock production is given. A mathematical model of a hybrid energy supply system based on a photo-solar-bio energetic installation is developed which makes it possible to reduce the energy intensity of agricultural production. Experimental results of studies of the effectiveness of the proposed hydro breeding system are presented.
