Energy efficiency trends for households in the EU
- Energy efficiency, as measured by ODEX, improved by around 29% (1.9%/year) over the period 2000-2018 (ODEX equal 71 in 2018), mainly thanks to improvement in space heating. Significant slowdown since 2015.
- ODEX aggregates energy efficiency gains by end-use, measured by the reduction in unit consumption. ODEX is calculated on the basis of 11 end-uses or large appliances: heating (toe/m2) (separation between new and existing dwellings), water heating, cooking, lighting, cooling (toe/dwelling), refrigerator, freezer, washing machine, dishwasher, dryer and TV (kWh/appliance).
- Decreasing energy efficiency gains since 2008 at EU level and in two thirds of Member States. Very significant slowdown for Romania, Slovakia, Austria, Germany and Slovenia. On the opposite, increasing trend in 10 countries such as Ireland, Portugal or Lithuania.
