The article highlights the focus on clean energy transition as the world celebrates Earth Day 2025 under the theme 'Our Power, Our Planet.' With nearly $2 trillion invested in clean energy globally last year, there is a significant push towards decarbonization. Despite the impressive progress, the question of balancing climate goals with national energy security remains crucial. Investments in clean hydrogen, battery storage, low-carbon fuels, solar, and wind are seen as vital components of the transition. However, challenges like supply chain bottlenecks and geopolitical tensions pose threats to this momentum. The article emphasizes the need for policymakers and investors to not only scale up renewables but also prioritize energy reliability and affordability through investments in grid infrastructure and energy storage. Emerging markets, despite their growing energy demand, receive disproportionately less clean energy investment, which hinders global progress and poses risks to achieving net-zero goals. Without adequate investment in clean energy infrastructure, these markets remain reliant on fossil fuel imports, impacting their energy security. The article stresses the importance of aligning finance and policy to mobilize capital and accelerate investments in clean energy, especially in emerging markets. Strategies like blended finance and transition bonds are highlighted as key to unlocking progress. The Sustainable Investment Forum Europe and Nature Finance Forum Europe are identified as platforms working towards a just energy transition and scaling finance for nature-positive solutions, aiming to translate ambition into action.
