Spaniards could reduce their energy bills by 27.4% with improvements in their habits and equipment. Slight modifications of the uses and customs would save 4.352 million euros to Spanish households in energy bills each year. These are data from the latest edition of the Home Energy Efficiency Index of the Naturgy Foundation, based on 3,600 surveys nationwide.
2018 was the first year that there was an increase in the Efficiency Index since 2011, standing at 6.4 points, 1.1% more than in the previous edition, an improvement that although slight implies a change in trend. Citizens are increasingly aware of the benefits of saving and efficiency measures, as reflected in the fact that last year, they had a greater potential for energy savings in equipment (43.3%) and heating (25, 3%), while the percentages were lower in lighting (20%), air conditioning (18.3%) and hot water (13.7%). «The energy that can be saved is almost 50,000 GWh, equivalent to 18% of the total electricity demand in Spain in 2017. With this saving, it would also avoid the emission of 14.7 million tons of carbon dioxide into the atmosphere , the same emissions made by 4.8 million passenger cars a year, 21% of the existing mobile fleet in Spain », explains the general director of the Naturgy Foundation, Martí Solà.
The habits that have improved in the last year, according to Naturgy, are as follows: Practically half of Spanish households had appliances of class A or higher (49.4%) and improved knowledge about labeling. The use of the short program in the washing machine also evolved positively and the tendency to select that the dishwasher automatically choose the washing program increased, improving the efficiency.
39% of the bulbs in Spanish households are led, followed by those with low consumption (34%) and the least efficient bulbs, incandescent bulbs, and only represent 9%. There is 27% more households that have contracted the hourly discrimination and a greater energy culture is reflected, since three out of four respondents know that, adjusting to their needs the tariff and the contracted power, they can pay less.
Among the negative aspects, the teams have increased in "stand by" in the homes and the number of houses that completely turn off the equipment before going out or going to bed has decreased. In addition, the systems for the reduction of air output in all windows in homes have worsened, the use of household appliances of greater consumption has increased simultaneously and the number of households without thermostats has grown to regulate individual heating.
The most efficient
The Naturgy Foundation also offers data on the most efficient homes. They are located in the Valencian Community, with a score of 6.61 points, followed by the Catalans (6.57%) and the Cantabrians (6.52%). Behind are Andalucía, Aragón and Murcia (6.50%) and Extremadura (6.49%). At the same level as the national average (6.46%), Madrid and Castilla-La Mancha are located. On the opposite side, below the average, Castilla y León, País Vasco (6.40%), Galicia (6.36%), La Rioja (6.34%) and Baleares (6.31%). The regions with the least efficient households are located in Asturias, Navarra (6.23%) and Canarias (6.01%). The profile of the most efficient households corresponds to a family of medium-high economic level, where he or the person in charge of the household is over 50 years old and the house is located in a municipality of between 10,000 and 100,000 inhabitants.
