Weekly Trends
The week of August 27 to September 3, 2025 reveals a global energy transition facing mounting geopolitical tensions. Oil prices remain volatile around $69/barrel for Brent, supported by US sanctions on Iran but pressured by OPEC+ production increases. Simultaneously, renewable energy investments reach record levels with $386 billion in the first half of 2025, while UK energy storage infrastructure adds 427 MW in August. This dynamic illustrates an energy reconfiguration where geopolitics and climate transition intertwine.
News
1. OPEC+ increases production by 547,000 barrels/day for September
The Organization of Petroleum Exporting Countries and its allies decided to boost oil production by 547,000 barrels per day starting September 2025, marking a complete reversal of previous cuts.
Analysis — This strategic OPEC+ decision reflects a delicate balancing act between preserving market share against rising non-OPEC production (US, Brazil, Canada) and the risk of creating a global surplus that would destabilize prices. The September 7 meeting will be crucial in determining the next phase of this strategy.
In brief — OPEC+ reverses its restriction policy to counter rising competitive production.
2. Renewable energy investments reach record $386 billion
The first half of 2025 sets a new record with $386 billion invested in renewable energy projects, representing a 10% increase from the previous year.
Analysis — This growth is driven by offshore wind ($39 billion) and distributed solar, while investments in utility-scale solar and wind decreased by 13%. This reorientation reflects risk reduction favoring smaller, more flexible projects in the face of regulatory uncertainties.
In brief — Investors now favor smaller renewable projects to reduce risks.
3. Brent price falls below $69/barrel despite geopolitical tensions
Brent oil closed at $68.99/barrel on September 3, down 5.10% from the previous year, despite US sanctions on Iran and Ukrainian attacks on Russian energy infrastructure.
Analysis — This paradoxical decline is explained by anticipation of a global surplus following OPEC+ production increases and the end of the US summer driving season. Geopolitical factors remain an upside risk but are currently dominated by supply and demand fundamentals.
In brief — Market fundamentals outweigh geopolitical tensions in oil price formation.
4. UK adds 427 MW of energy storage in August 2025
The British battery storage sector completed 427 MW of new capacity in August, notably including Statera’s 300 MW Thurrock project, which became the country’s largest.
Analysis — This massive expansion of British energy storage (bringing the total fleet to 7,582 MW) illustrates the necessary acceleration to support intermittent renewable energy integration. The UK is becoming a global laboratory for energy flexibility.
In brief — The UK massively strengthens its storage capabilities to support the energy transition.
5. Shell abandons biofuels¹ project in Rotterdam
Oil giant Shell cancelled its plans to build a biofuels¹ facility in Rotterdam, revealing the persistent challenges of transitioning to alternative fuels.
Analysis — Shell’s decision reflects the economic and technical difficulties encountered by oil majors in their diversification into biofuels. Challenges include feedstock volatility, competition with food supply, and the still uncertain profitability of these sectors.
In brief — Oil majors struggle to realize their biofuel ambitions due to economic challenges.
6. European Union approves five new cross-border renewable energy projects
The European Commission added five cross-border renewable energy projects to its official list, including a 1 GW offshore wind farm in the Baltic Sea.
Analysis — These cross-border projects represent the future of European energy integration. The Liivi Bay offshore wind farm (Estonia-Latvia) and the MedGen project (Algeria-Tunisia-Italy, 10 GW) illustrate how the EU diversifies its supply sources while strengthening its energy sovereignty.
In brief — Europe accelerates its energy integration through strategic cross-border renewable projects.
7. United States plans record 64 GW of new energy capacity in 2025
US developers are planning to add 64 GW of electrical capacity in 2025, with more than half from solar, setting a new historical record.
Analysis — This record expansion demonstrates the technological and economic maturity of American solar, particularly in Texas which becomes the leading state in solar capacity. Support from battery storage (5.9 GW in the first half) shows the growing sophistication of the US electrical system.
In brief — The United States is set to break its record for energy capacity additions, driven by solar.
8. American nuclear renaissance: policies and private investments converge
American nuclear energy is experiencing renewed interest in 2025 with regulatory reforms, private investments, and advanced reactor projects, notably to power artificial intelligence² data centers.
Source: The National Law Review
Analysis — This American nuclear renaissance, supported by the ADVANCE Act and orders from tech hyperscalers, responds to growing demand for stable energy for AI. Public-private partnerships and new modular reactor designs are transforming the American nuclear landscape after decades of stagnation.
In brief — American nuclear power is reborn thanks to AI energy needs and regulatory reforms.
Strategic Outlook
The convergence of geopolitical, technological, and climate factors is redefining the global energy landscape. OPEC+ adapts its strategy against rising renewables and non-OPEC production, while record investments in cleantech demonstrate accelerating transition despite geopolitical uncertainties.
The emergence of energy storage as critical infrastructure and the nuclear renaissance to power the digital economy illustrate the growing sophistication of energy systems. The next decade will be decisive in determining whether this dynamic can overcome geopolitical and economic resistance to energy transition.
