Per year
Implementation of Ecodesign and Energy Labelling directives will lead to 3 TWh energy savings 2030
Despite rise in population and ownership of appliances
Results are based on study of 10 appliances
Survey in 2000 householdsTechnical information on appliances
2. Ecodesign and energy labellingTotal energy demand of the appliances
National energy agencyEnergy efficiency and GHG reductions
Support schemes -all sectorsIndustry, transport, buildings
Market transformation, demo, pilots
The schemes give substantial savings
3. Schemes and funding from Enova
Source: Enova
3. Schemes for research –Centres for Environment- friendly Energy Research (FME) - (2017-2024)
Norwegian CCS
Research Centre - NCCS
Norwegian Research Centre for
Hydropower Technology- HydroCen
Centre for intelligent electricity distribution –
CINELDI
Centre for an Energy Efficient and Competitive
Industry for the Future - HighEFF
The Research Centre on Zero Emission Neighbourhoods in
Smart Cities – ZEN Centre
Mobility Zero Emission Energy Systems - MoZEES
Research Centre for Sustainable Solar Cell Technology
Norwegian Centre for Sustainable Bio-based Fuels and Energy - Bio4Fuel
Research Centre on Zero Emission Neighbourhoodsin Smart Cities – ZEN

Heat pumps
Solar PV systems
4. Local energy production
Foto: L. Henden
Large growth since 2003Mainly due to support schemes and regulation
Air-air pumps dominant in households
Estimated heat production in 2030 -> 15-18 TWh,
Of which ambient heat > 10 TWh
Huge rise in installation of heat pumps
Solar PV - Massive growth, but the volumes are low

Important learnings
Design and management of schemes are important Must meet actual needConsumers addressed must have possibility to respondMeasure, follow up, redesign and cancel (..) schemes
Don’t forget rehabilitationin 2040, the majority of the area in the buildings sector is still “old”. Use opportunities when houseowner are in decision processesCompetence in building sector important – poor work can spoil good technology
Research and pilots should meet needsEnforce technology and market mechanisms
Some final remarks
