The subject of the study is geo-ecological aspects of geothermal energy. It is revealed that the high dependence of geothermal resources utilization on the state support makes the development of geothermal deposits dependent on the economic situation in the country or in a particular region. The way out of this situation is to diversify the use of geothermal resources, for example, by creating geothermal energy-biological complexes that combine the integrated use of energy and thermal potentials of geothermal deposits. The main characteristics of such a complex are given on the example of Ternair geothermal field in the Republic of Dagestan. It is shown that the potential efficiency and investment attractiveness of projects of geothermal energy-biological complexes promotes attraction of private investments for their realization. It is concluded that the main geo-ecological risks are reduction of groundwater temperature, depletion of geothermal resources, deformation of surface relief and activation of microseismic activity, chemical pollution of surface relief, corrosion of well equipment and surface circulation system, deposition of minerals from groundwater. Modern technologies make it possible to effectively solve these problems.
