5 star-rated appliances may only trim your energy costs

Demand for energy efficient appliances is rising as people look to reduce their electricity bills. Salespeople are promoting 5-star labelled air conditioning units as they consume up to 25% less energy than lower-rated models. Although these units cost more, they can help users save money over time. However, a study by the Centre for Science and Environment has found that during peak summer temperatures a 5-star AC can consume up to 28% more power.
