After decreasing steadily for years, household electricity consumption in 2010 reached its highest level in two decades, says a report by the European Commission.
Between 2005 and 2009, overall residential energy consumption in the EU member states fell after years of growing rapidly, reaching a peak of 1,192,536 kilotons in 2005.
Between 2008 and 2009 total final energy consumption decreased by as much as 5.2% in the residential sector.
But now, according to the Energy Efficiency Status Report 2012 by the EU Commission's Joint Research Centre, the figure is on the rise again. Between 2009 and 2010 residential energy consumption increased by 3.6%.
Household consumption accounted for 26.7% of total final energy usage in 2010 in the EU. Only the transport sector took a bigger share of the total (31.7%).
The industry and the services sectors are both smaller in terms of final energy consumption with a share of 25.3% and 13.2% respectively. The residential sector therefore plays an important role in energy efficiency programmes and policies, the Commission says.
Between 2005 and 2010, only six EU member states had negative growth rates in residential electricity consumption: Malta (-23.8%), Belgium (-22%), Slovakia (-7.2%), the United Kingdom (-5.6%), Sweden (-5.3%), and Denmark (-0.6%).
Data indicates that Finland has the highest residential energy consumption per capita and Malta the lowest.
The three countries with the highest consumption per capita – Finland, Luxembourg and Denmark – also have above average GDP per capita.
Higher GDP levels may mean homeowners to buy more energy intensive technology resulting in higher consumption, but economic growth can also lead to more energy efficient equipment resulting in lower consumption levels, the Commission says.
Uncertain cause of the rise
The authors of the report say the the increase in energy consumption could be related to weather conditions as the winter of 2009/10 was unusually cold in Europe. However, other elements have to be taken into consideration such as a growing population and economic factors, the report says.
Dr. Brigitta Huckestein, senior manager for energy and climate policy at German chemical giant BASF, said falling energy consumption was mainly caused by the economic downturn and not by policy measures to improve energy efficiency.
"The increase of energy consumption since 2009 is mainly related to an economic recovery after the financial crisis in 2008. Recovered growth creating energy consumption should not be considered as the wrong direction," Huckestein told EURACTIV.
To reverse the upward trend, she said BASF supports energy efficiency targets in all sectors, based on their respective economic potential.
At the same time member states should set energy efficiency targets for buildings and take measures to increase the rate of deep renovations to effectively reduce energy demand and create new jobs, Huckestein stressed.
The EU's Energy Efficiency Directive, which was adopted in October, will have positive effects for the building sector, she said.
"But we are concerned about the absolute cap on energy consumption set by the Energy Efficiency Directive. A cap is not an appropriate measure as it may limit energy supply and increase regional production costs", she said.
"Restrictions of absolute energy use set unnecessary barriers to growth in the EU which needs to recover to overcome the current crisis."
