FRANKFURT, Germany (AP) — Europe is staring down a winter energy crisis. Russia has reduced natural gas supplies as Europe supports Ukraine, and the continent’s ability to get through the winter may depend on how cold it is and competition from Asia. The lights of the Eiffel Tower are turning off earlier than normal and shop windows across Europe are going dark to save energy. High prices mean households and businesses are trying to use less heat and electricity, but they’re running into the hard truth that cutting back only shaves a little off their bills. Governments are rolling out relief and have been able to bolster natural gas storage. But analysts say Russia still has leverage with energy prices high and supplies tight.
