What are the common causes of high energy bills and how can I reduce them?

Common causes of high energy bills can be attributed to various factors. One primary cause is inadequate insulation, which leads to heat or cool air loss from your home. Inefficient appliances, such as old refrigerators or HVAC systems, can also significantly contribute to higher energy consumption. Other common culprits include excessive use of electric heating, cooling, or hot water systems, as well as leaving lights on unnecessarily. To reduce energy bills, Duke Energy recommends taking several steps. These include sealing air leaks, improving insulation, regularly maintaining appliances, using energy-efficient lightbulbs, adjusting thermostats to optimal temperatures, and encouraging energy-conserving habits like turning off lights when not in use. Duke Energy offers various resources, including energy audits and rebates for energy-efficient upgrades, to assist customers in reducing energy consumption and saving money.
