Energy demand in Italy

In 2009, according to preliminary figures, domestic energy demand amounted to 317,602 GWh, a decline of 6.4% from 2008. In order to compare 2009 figures with those of the previous year, a number of factors need to be considered. First of all, there is the variation in the calendar. Although there are fewer total days than the previous year (2008 was a leap year so there were 366 days), there was one more business day in 2009. Secondly, weather conditions were different. In 2009, the first three months were cooler on average than the same months of 2008, whereas the remaining months (from April to December) were slightly warmer than in the prior year. Therefore, adjusting for both number of days and temperature, the change in electricity demand came to -6.6%.
