Europe’s Energy Crisis Tests the Limits of Scientific Advice
Expert evidence is abundant but political decisions still follow a different logic.
European governments are weighing subsidies, price controls and emergency measures as energy markets react to renewed disruption in the Strait of Hormuz.
Scientific advisers say the response follows a familiar pattern. Evidence on how to reduce exposure to energy shocks is well established, but it rarely determines decisions in moments of crisis.
Shipping disruptions linked to the conflict involving Iran have again pushed energy security to the top of the European agenda. Prices surged and remain volatile, even as signs of possible de-escalation have eased immediate pressure.
For policymakers in Brussels, the priority is short term: stabilizing prices, protecting households and maintaining industrial output. For scientific advisers, the diagnosis is longer term and largely unchanged.
A year ago, the European Academies Science Advisory Council warned that Europe’s reliance on imported oil and gas left it exposed to supply disruption and price swings. Its report argued that the only durable response was to accelerate domestic energy production through renewables, storage and grid modernization.
The analysis was widely circulated but carried no binding authority.
“That is both the strength and the limitation of scientific advice,” Alessandro Allegra, EASAC’s program director for energy, said in an interview with The Science Diplomat.
“Our most recent advisory reports on security sustainable energy supply have actually identified many of the vulnerabilities that we have seen in the most recent crisis and offered evidence-based advice on how to address them,” he said. “These are well-known vulnerabilities within the scientific community and also within the policy-making community, but the attention was not there.”
He said those risks had been recognized well before recent crises. “The risks of over-dependence from a single supplier of fossil fuels had been flagged for many years in the scientific community and in the policy community, but they were not acted upon.”
Advice without authority
EASAC brings together national academies to synthesize scientific evidence for policymakers. Its reports are independent and peer-reviewed, designed to inform decisions rather than direct them.
Scientific advice competes with electoral pressures, industrial interests and national priorities. Whether it shapes outcomes depends on how it fits those pressures.
“Many interests and voices are making themselves heard,” Allegra said. “It is important that the voice of science, channelled through the academies of Europe, is heard.”
Advisory work has also pointed to structural features of Europe’s energy system that increase risk, including a market approach to fossil fuel procurement that prioritizes the lowest price and leaves countries exposed when conditions shift.
Advisory systems have become more formalized over the past decade. The European Commission relies on a Group of Chief Scientific Advisors, and national governments have expanded their own advisory bodies. Consultation has increased, but authority has not.
When crisis hits
Energy shocks make that gap visible. After Russia’s invasion of Ukraine in 2022, scientific analysis supported efforts to diversify supplies and accelerate renewables. Technical coordination across European institutions worked effectively.
Political decisions remained national. Germany introduced a €200 billion support package. France expanded support for nuclear energy. Spain imposed price caps. Each response reflected domestic pressures as much as shared European goals.
The current disruption follows a similar pattern. Governments are again considering short-term measures while reaffirming long-term commitments to the energy transition.
Scientific evidence points to reducing dependence on imported fuels and expanding domestic capacity. Political systems, under pressure, focus on immediate relief.
Translating evidence into policy
Between evidence and decision lies a process of translation. Advisory bodies present findings in forms policymakers can use, but that process involves choices about emphasis and timing.
Allegra said scientific advice can identify options and trade-offs, including how different policy responses affect markets and behavior.
“Policy decisions are not based on facts alone,” he said. “Scientific evidence is fundamental to designing good policies which are effective and achieve the desired results, but it cannot alone guide policy decisions.”
Europe has no shortage of scientific advice on energy policy. EASAC, European Commission advisory bodies and national academies all produce extensive analysis. Yet evidence alone does not determine outcomes.
Scientific advice can identify risks and outline options, but political decisions reflect a wider mix of economic, social and national considerations. Nations retain control over their energy mix, and responses vary accordingly.
The immediate focus remains stabilization, even as officials acknowledge the need for structural change.
“Beyond managing the immediate energy crisis, our key priority is to structurally transition to an electrified economy, including by reducing the relative price of electricity compared to fossil fuels and by reinforcing grids,” the European Union’s economy commissioner, Valdis Dombrovskis, told a European Parliament committee.
“This is the only solution to permanently protect the E.U. from the volatility of fossil fuel prices and supply conditions.”
