Forty years after Chornobyl, military strikes and near-misses at nuclear sites in Ukraine and Iran show the same catastrophic risks remain. The 1986 reactor explosion killed at least 30 people; later studies link tens of thousands more deaths to radiation-related illnesses, and birth defects rose roughly 200–250% in the worst-affected zones. Hundreds of thousands were displaced and large areas remain contaminated — recent strikes, and an IAEA confirmation that impacts reached within 75 metres of Iran’s Bushehr plant, underline that these dangers are not only historical.

Chornobyl's long shadow

The 1986 Chornobyl accident created a geography of loss that still affects land use, health services and budgets. At least 30 people died immediately; later studies link tens of thousands of additional deaths to radiation-related diseases, and birth defects rose roughly 200–250% in the most affected areas. Hundreds of thousands of residents were displaced and contamination, chronic illness and long-term costs have persisted across generations.

Those outcomes illustrate how a single failure in a centralised system can produce consequences that are hard to contain: cleanup can take decades, land can be removed from productive use, and medical and social costs can carry on long after the event.

New risks at active nuclear sites

Nuclear risk is current, not only historical. Forces occupied the Zaporizhzhia Nuclear Power Plant in Ukraine and a Russian drone attack damaged the New Safe Confinement at Chornobyl. The International Atomic Energy Agency (IAEA) has confirmed strikes reached within 75 metres of Iran’s Bushehr Nuclear Power Plant. These incidents show nuclear sites can be threatened by military action as well as accidents.

How fossil fuel fragility compounds the problem

Conflicts have also exposed weaknesses in global fossil fuel systems. Disruptions to key routes such as the Strait of Hormuz have driven up oil and gas prices, which push through to transport, food and household energy bills. Both nuclear and fossil systems concentrate risk in large, centralised infrastructure — single points of failure that are easier to disrupt during geopolitical tensions or extreme weather, with both local and global consequences.

Decentralisation and storage as an alternative

Shifting from concentrated systems toward distributed energy backed by storage offers a practical policy response. Core benefits include:

  • Resilience: Rooftop solar, community wind and other local generation reduce dependence on a small number of large plants or chokepoints, making it harder for a single event to cut power to large areas.
  • Security: Smaller, dispersed sources are less attractive and more difficult targets in conflict scenarios; they can continue to serve local needs even if major infrastructure is damaged.
  • Market stability: Paired with batteries or other storage, distributed systems smooth demand spikes and reduce sudden pressure on fuel supplies, helping to limit price volatility.

Combined, decentralised generation and storage lower both the security risk posed by concentrated infrastructure and the economic risk that comes from brittle fuel supply chains.

The IAEA’s confirmation that strikes reached within 75 metres of Bushehr underscores the ongoing danger to nuclear sites. Decentralising energy generation and adding storage would reduce both the security risk of concentrated infrastructure and the economic fragility that makes societies vulnerable during conflict.
