As shown by various studies, the greater use of more efficient appliances did not result in a price increase for consumers, as producers were able to adapt and benefit from increased sales (“learning effect”). Programmes oriented toward motor energy efficiency appear to have produced significant and cost-effective results when of sufficient size and having enough resources to attract participation (IEA, 2006). However, none of the programmes introduced were able to reverse or stop the increase in electricity consumption in the domestic appliance sector.
