About this update from Duke Energy Corporation (holding Company)

ST. PETERSBURG, Fla., June 19, 2026 /PRNewswire/ -- While summer heat has already settled across Florida, the astronomical start of the season is observed this Sunday, June 21. Duke Energy Florida is helping customers manage their energy use – and their bills – by offering practical tips focused on the five appliances that use the most energy in the home: air conditioners, water heaters, refrigerators, washing machines and dishwashers.The big five: Air Conditioners: Set the thermostat to the highest comfortable temperature and raise it a few more degrees when leaving home.

For additional savings, use cold water whenever possible.Dishwashers: Use the dishwasher's "eco-mode" and/or the air-dry or overnight-dry settings (instead of the heat-dry setting) to save water and energy.Our view:"Duke Energy Florida is here to help our customers take control of their energy use this summer," said Melissa Seixas, Duke Energy Florida state president.
