Münster (Germany) – The RENIXX continued its upward trend for much of last week and marked new annual highs. On 06/05/2026, the index reached a new intraday high of 1,423.41 points. Already on 05/05/2026, a new annual high on a closing basis was recorded at 1,413.45 points. Towards the end of the week, however, a consolidation set in with noticeable declines.
Green stocks between AI-driven electricity demand and falling system costs
The current week once again highlights the high dynamics in the global energy sector. Increasing attention is being paid to the rapidly growing electricity demand from data centers and AI infrastructure, which is creating new demand impulses for flexible and decentralized energy supply.
At the same time, the International Renewable Energy Agency (IRENA) sees a turning point in global electricity costs. According to the new report “24/7 renewables: The economics of firm solar and wind,” combined wind and solar systems with battery storage are now cheaper than new coal and gas power plants in many regions.
The drivers are sharply declining technology and storage costs. Since 2010, investment costs have fallen by 87% for solar energy, 55% for onshore wind, and even 93% for battery storage, according to IRENA. This is shifting the cost structure of power systems increasingly in favor of renewable energy and flexible storage solutions.
