In recent years we have seen real benefits from energy efficiency. In 2016, in China, the average household saw a 25 percent drop in energy bills due to efficiency efforts. In the same year, German consumers saved nearly USD 580 per person, due to home and vehicle-related efficiency programs. Countries that have already reached relatively low energy intensities, such as Japan and Italy, continue to make progress, too. Yet, despite the cost-effective savings and wide-ranging health and environmental benefits, few countries are prioritizing energy efficiency in their economies. Also, investment in energy efficiency is nowhere near the required levels. We need to see larger gains in the residential sector, which is the fastest growing energy-consuming sector, especially in low-income countries.
