Ukraine, including Kyiv, is struggling to cope with a new wave of rolling blackouts after relentless Russian attacks took out half the country’s power generation capacity.

Residents and businesses of Kyiv are adapting to the absence of electricity using generators, power banks, and flashlights and even recalculating their bathroom visits. Heavy damage inflicted to the country’s power system has left millions feeling uncertain about Ukraine’s ability to meet the national electricity demand after the warm weather months are over and the weather turns cold.

The circumstances force businesses and households to rely on alternative sources of electricity and light to get through a day as the summer heat makes more and more people use air conditioners. And many are worried the situation could get even worse.
