Why is my electric bill so high in the summer?
Modern homes with new air conditioning and energy-efficient appliances are mysteriously consuming up to 37.7 kWh per day—reaching nearly 4,000 kWh and $800 a month. This unexpected surge makes it impossible to understand why energy usage is over 60% higher than typical household averages.
