In a worst-case scenario, blackouts were expected to reach 20 hours a day. Greenpeace warned in November that Ukraine’s power grid faced a "heightened risk of catastrophic failure.” But thanks to a combination of unseasonably warm weather, and Ukraine’s ability to adapt to a third year of Russian campaigns against its energy system, the worst has not come to pass.Since Russia began targeting Ukraine’s energy infrastructure in late 2022, the country has learned to better protect the power grid, figuring out how to make repairs in record time following Russian strikes. Climate change — which has been causing warmer winters each year in Ukraine — has also become Ukraine's unexpected ally in resisting Russia’s tactic of freezing Ukrainians into submission.“The fact that we have such warm weather of +6, +7 degrees Celsius (42-44 degrees Fahrenheit) is fantastically positive for us,” said Oleksandr Kharchenko, managing director of the Energy Industry Research Center, crediting the mild winter as a main factor for the lack of problems with power in Ukraine.
