The knock-on effects of the conflict in the Middle East are awakening ghosts of crises past that shook the European Union.

Seven months into Russia's full-scale invasion of Ukraine, the President of the European Commission stood at her podium in the European Parliament and accused Russia of manipulating the EU's energy market.

They prefer to flare the gas than to deliver it, proclaimed Ursula von der Leyen, as spiralling energy prices hit consumers across the continent. This market is not functioning anymore.

Fast forward four years and deep energy-linked frustration rumbles through Europe once again.

We swore we'd learn. We promised things would change but here we are, a frustrated European diplomat shared anonymously.

Europe's growing energy shock, triggered by the burning conflict in the Middle East, threatens to dominate a summit of European leaders in Brussels.

Instead of concentrating on much-needed long-term plans for improving competitiveness, European heads of state are panicking over energy prices, scrambling for immediate solutions.

A lot has changed since 2022, when Europe decided to phase out its reliance on Russian energy resources following Russia's invasion of Ukraine. The EU succeeded in cutting its dependence but now finds itself reliant on other suppliers like the US and Norway.

As energy prices skyrocket in 2022, countries like Italy and the UK felt pressured to aid consumers. The term diversification became a buzzword in Brussels corridors, with the EU vowing never again to rely solely on one energy provider.

However, four years later, the dependency remains, and with events in Iran threatening to disrupt global energy markets, Europe's energy security hangs in the balance.

Energy-hungry Germany, for instance, now depends heavily on US liquefied natural gas (LNG), raising questions about its own autonomy and stability.

As tensions rise again in the Middle East, European energy leaders meet to assess the threat posed to their energy supplies and the socioeconomic implications for their citizens.

This crisis highlights the need for Europe to reconsider its energy strategy, not just in terms of suppliers but also in terms of sustainability and resilience against global price shifts that threaten economic stability.
