Variable speed-controlled exhaust air heat pumps save a lot more energy than older models with on/off technology, especially in buildings with a high energy use. This is shown by tests that have been carried out on exhaust air heat pumps by the Swedish Energy Agency.

A normal-sized house with underfloor heating can save up to 80 per cent of the building's heating requirement with the right geothermal heat pump. Tests show that geothermal heat pumps have been developed and become more efficient in recent years.

The Swedish Energy Agency and SoWiTec have signed an agreement on 600,000 CERs generated by the wind farm Minas I, located outside the town of Minas in southeastern Uruguay.

LED and reflector lamps are now subject to ecodesign requirements. Energy marking is being extended at the same time, so that it will be easier to purchase an energy-efficient lamp.

There was a significant increase in the share of renewable energy within the transport sector last year, and at present the preliminary figure for 2011 is 9.8 per cent. At the same time, the total energy use in the sector decreased.
