In autumn 2024, Russia launched massive aerial assaults on Ukraine, pounding its energy system [1]. Several nuclear reactors were disconnected from the grid due to the assaults; one shut down entirely [2]. The attacks have damaged or destroyed more than half of Ukraine's power generation capacity [7]. The International Atomic Energy Agency has called the situation "the world's biggest threat to nuclear safety" [8].
Nuclear Vulnerability
Ukraine still depends on nuclear energy for more than half of its electricity [6]. Nuclear plants rely on constant external power supply to run cooling systems; if the grid fails, they switch to diesel generators [4]. Shaun Burnie, a Greenpeace veteran nuclear specialist, has warned of the risks [3]. The memory of Chernobyl looms: on April 26, 1986, a reactor at the Chernobyl nuclear power plant exploded [5].
The Case for Decentralized Renewables
Centralized power plants are easy targets. Chris Aylett, an energy specialist at Chatham House, notes that a single missile can take out a 250-megawatt coal plant, but it would require 40 to destroy the same capacity in wind generation [10]. Solar parks are more resistant to attacks than centralized plants [11]. Rooftop solar now covers hospitals, schools and public buildings in Ukraine [12]. In 2025, Ukraine installed enough solar to power over a million homes [13].
Ecoclub's Solar Aid Campaign
Lena Kondratiuk is a renewables analyst at NGO Ecoclub [14]. Ecoclub launched the Solar Aid for Ukraine campaign after the full-scale invasion in 2022 [15]. Kondratiuk has helped bring nearly 90 solar systems online [16]. Solar and battery systems keep water utilities running during blackouts in Ukraine [17]. Kondratiuk installed solar panels at a care home for women with mental health conditions [18].
"Renewable energy in Ukraine is not about the climate and sustainability; it's about surviving now," Kondratiuk said [19]. "I still want to help my country, still want to continue my work at the Ecoclub, and I still think that even after the war and after our victory, there would be even more work compared to now because we have to rebuild the country and rebuild it in a greener and better way" [20].
Lessons for Europe
Chris Aylett said the war and the conflict in the Strait of Hormuz have made the case for rapid decarbonization and renewables in "fossil-fuel poor" Europe [21]. But he added that in countries such as France, where nuclear is a major energy source, he sees no reason for that to stop [22].
What to Watch Next
As Ukraine rebuilds, the choice between centralized nuclear and distributed renewables will shape not only its energy security but also the template for other nations facing hybrid threats. The success of solar-plus-storage in wartime may accelerate Europe's shift toward decentralized, resilient grids.
