ЕКОЛОГО-ЕКОНОМіЧНА КОНВЕРГЕНЦіЯ: ПЕРЕХіД ДО СТіЙКОї ЕНЕРГЕТИКИ

Sustainable energy development is complex challenge, so only complex decisions and approaches could be possible to implement in the most efficient way. There is still open question what is the optimal volume of new energy resources using to support sustainabledevelopment and environment safety for any state of the world. Article deals with the availability of convergence to serve for the moreeffective usage of analytic and system approaches for modeling ecological-economic spillovers in the case of transition to sustainableenergy. The economic effects of sustainable energy transition are considered. The analysis of dynamic of energy consumption in thescale of different type of resources during 1820-2030 years depicted the situation of complicated analysis of "economy-energy environment" linkage. It arises the agenda of necessity to implement complex approaches for modeling and forecasting of new energy systems development. Different types of models and techniques to analyze economy-energy systems are listed and compared.
