"Energy Conservation Urged by Ameren During Heat Wave"

Ameren is urging customers in Missouri and Illinois to conserve energy during the dangerous heat wave by raising thermostat temperatures, using curtains and blinds to block out direct sunlight, and deferring high-energy appliance usage until the evening hours. The company hopes to lessen strain on the grid and ensure safe and reliable service. A slight cooldown is expected, but high temperatures could still peak in the 90s.
