Digital Tools and Information Systems in National Strategies for Sustainable Green Energy Transition

Abstract

This paper analyses national policies for the move towards green energy, considering global tendencies, investment dynamics, and socio-economic policy instruments in place between 2013 and 2024. This study further investigates the main drivers of growing renewable energy generation, investment amount, tariff systems and policies, tax-justice policies, subsidies, technological innovation, and international inter-investment. The study uses statistics from international and national organizations, regression analysis, comparative analysis, and scenario forecasting methods to determine the most effective measures for promoting green energy transition. The findings demonstrate that countries succeed in implementing renewable energy if they combine economic tools, of which the annual investment amounting to over 500 BN USD takes a significant share. Not only does technological advances, especially the decrease in the cost of solar and wind technologies, considerably enhance the competitiveness of renewable systems. In addition, upgraded infrastructure and regulatory mechanisms contribute to long-term sustainability. Analytical tables and charts in the article show investment directions, modeling results, and projection contents for major global areas. The study offers, at best estimation, a theoretical and integrated approach to the literature that combines investment patterns, policy tools, and scenario types into a single analytical frame for evaluating national green policy strategies. By analyzing the systemic connections between financial flows, policy instruments, and renewable energy development, we build on previous research and address methodological blind spots in comparative strategy investigations. In practical terms, these results provide evidence-based advice to governments, policymakers, and investors. The findings could contribute to improving national policies, strengthening tariff and subsidy structures, and better informing public and private investments. These findings can inform how countries can enhance energy security, reduce emissions more quickly, and stay on track with their long-term climate goals. The report argues that the development of international relations and further investment in new technologies are crucial for achieving a secure transition to green energy.
