Russia has launched a widespread drone attack across Ukraine, targeting the country's energy network, with an unprecedented number of drones reaching Transcarpathia following the end of a Moscow-requested ceasefire.

Russia has struck Ukraine's energy grid 2,500 times in four years, leaving millions without heat in freezing weather.

Attacks on Ukraine's energy grid have accelerated a shift in its energy model, leading to the construction of a more resilient network with less centralization and more renewable sources.

The United States and Ukraine are discussing plans for post-war reconstruction, even as Russia continues to target and damage Ukraine's energy grid.
