The article considers the significance of the problem of renewable energy and energy saving technology development. The potential of solar and geothermal energy in the Russian Federation, the feasibility of using stable and inexhaustible renewable energy sources for implementation in buildings and structures are discussed. Construction, operation of buildings and structures consume up to half of all generated energy in the world. The efficiency of enclosing structures significantly affects the energy saving of buildings and generates up to 30% of heat losses. Using renewable energy technology in construction is effective with enclosing structures with high thermal insulation characteristics. Territories of the Russian Federation with decentralized energy supply, characterized by low consumer power, lack of access to power grids, lack of fuel, harsh climatic conditions, and low population density, have a high potential for the implementation of renewable energy sources (RES) into the buildings.
