The project of large-scale stage-by-stage implementation of energy systems based on solar energy and other renewable energy sources (RES) in rural settlements of Russia has been worked out. Research was made based on the analysis of regional, climatic, social, economical and technical factors, proposed complex approach to energy supply of rural buildings and predictive estimates. Priorities, sequence of actions and the values of interstage and final indicators have been defined. The issues of RES implementations and measures on energy saving over vast, mainly poorly populated, rural territories have been considered.
