Abstract. This article analyzes the significance of the ecological crisis and economic changes in the context of green energy and renewable resources. In recent decades, climate change, air and water pollution, and the depletion of natural resources have intensified global environmental challenges. Simultaneously, economic systems are undergoing rapid transformations, with energy and production sectors facing sustainability issues. The article examines green energy technologies, including solar, wind, hydro, biomass, and geothermal energy, and their role in promoting ecological sustainability and economic development. Furthermore, it discusses how the use of renewable resources allows countries and enterprises to achieve energy independence, create jobs, and enhance economic efficiency. The study emphasizes that green energy and renewable resources are essential for ensuring environmental security, sustainable economic growth, and long-term resilience.
