विशेषज्ञों का कहना है कि परमाणु संलयन की लागत के मॉडल व्यवहार्य होने के लिए बहुत आशावादी हैं

The recent analysis from ETH Zürich challenging the economic viability of nuclear fusion presents a critical juncture for global energy policy, particularly for nations like India committed to aggressive decarbonization targets. While the allure of limitless, clean fusion power is undeniable, this research underscores the imperative for pragmatic resource allocation in climate mitigation efforts. Overly optimistic cost projections for nascent technologies risk misdirecting substantial public and private capital that could otherwise accelerate the deployment of proven, cost-effective renewable energy solutions.

India's energy strategy must prioritize a balanced portfolio. Investing in advanced research like fusion is essential for long-term energy security, but it cannot come at the expense of scaling up solar, wind, and hydropower. The 'experience rate' concept, demonstrating how solar and battery costs plummeted due to mass production and technological learning, offers a valuable lesson. Fusion's inherent complexity, large-scale requirements, and custom-built nature inherently limit its potential for rapid cost reduction through mass manufacturing.

Policymakers must demand rigorous, evidence-based cost-benefit analyses for all major energy R&D projects. Public funds, often scarce, must be deployed where they yield the highest impact on emissions reduction and energy access in the near to medium term. Diverting funds from established green technologies, which are already competitive, would be a strategic misstep, potentially delaying India's climate goals and hindering economic development.

Therefore, while maintaining a strategic interest in fusion and supporting foundational research, India should intensify its focus on accelerating the deployment of existing renewable energy technologies. This includes strengthening grid infrastructure, improving energy storage solutions, and fostering domestic manufacturing capabilities for solar panels and batteries. A pragmatic approach ensures that India's energy transition remains robust, economically sound, and aligned with its ambitious climate commitments.
