Overall, Germans are using more energy at home again – despite all efforts to save money. There are several reasons for this.

Since 2014, households have been using more heating energy per square meter of living space again.

Dhe energy consumption of private households for space heating, hot water, lighting and electrical appliances rose again last year. In 2017, a total of 679 billion kilowatt hours were used for this, as the Federal Statistical Office announced on Thursday. That is around 1.5 percent more than in the previous year.

The lion’s share is the energy used for heating – more than 70 percent of household energy is used for this. This is followed by hot water with 14 percent and household appliances with 8.2 percent. The statisticians put cooking, drying and ironing at a share of 5.6 percent of the total energy consumption of private households. Lighting, on the other hand, only accounts for 1.5 percent.

With the increase in 2017, the trend of the past few years is solidifying. While energy consumption fell significantly between 2000 and 2014, it has steadily increased again since then.

More one- and two-person households

There are several reasons for this increase in spite of all energy efficiency efforts: For example, heating energy consumption has increased by 2.1 percent since 2010. However, the energy consumption per square meter of living space – the so-called energy intensity – fell during this period.

According to the Federal Statistical Office, the fact that absolute consumption nonetheless increased is mainly due to the fact that the population grew by three percent between 2010 and 2017 – and energy consumption increased with it.

In addition, the proportion of one- and two-person households that have a higher per-capita energy requirement than multi-person households increased. Since 2014, however, the energy intensity has been increasing again: households are again using more heating energy per square meter of living space.
