Countries are facing interconnected and cascading crises, including COVID-19, climate change, wars and military conflicts, and disruptions in geopolitics. To address these global challenges, it is necessary to introduce eco-innovations, and implement renewable energy. The purpose of the article is to analyze the countries' eco-innovative development, determine the impact of factors on alternative energy sources consumption, and consider models for eco-innovation network management. The dynamics of the Global Innovation Index, the European Innovation Scoreboard, and the EcoInnovation Index were analyzed. The research implements the analysis of 27 EU countries for the period 2013-2020 by indicators that influence the eco-innovations development. The model of the impact of countries' investment development and economic growth indicators (such as foreign direct investment; GDP per capita), management level and the willingness of the government to invest in eco-innovation (total tax and contribution rate; government effectiveness; control of corruption; rule of law; research and development expenditure), and the level of income inequality (income share held by highest 10%; Gini index) on the consumption of alternative energy sources, energyefficient technologies, and waste management and recycling implementation was built. The linear and cybernetic models for eco-innovation network management were considered. The pace of eco-innovation is strongly influenced by the effectiveness of state eco-innovation policies, the availability of a comprehensive information base, and the mechanisms of interaction between the science and production sectors. Effective eco-innovation networking implies that between the participants there are different types of relationships, the main of which are economic; legal; administrative; technological; social; and informational.
