There are 25 winners from 14 countries across the three categories featured in this year's edition of the energy efficiency awards managed by the Joint Research Centre, the European Commission's in-house science arm. These award schemes are part of three JRC programmes aiming to encourage organisations in both public and private sectors to cut energy consumption by using innovative and energy efficient technologies. Under the GreenLight programme, the winners include the Delhaize supermarket chain (Belgium), which reduced its annual energy consumption for lighting across more than 130 supermarkets by a total of over 20 000 Megawatt hours (MWh), a 60% reduction. Typically, a household consumes 4 MWh per year. Under GreenBuilding, one of the best refurbishment projects, Alfred Arnold Verladesysteme (Germany), has achieved over 78% energy savings in its office and workshop building, while the new Vasakronan AB Riga 2 office building (Sweden), has pared back consumption to only 40% of that allowed by law. In the third category, Motor Challenge, SATA Fiat group (Italy), obtained energy savings of nearly 15 000 MWh in its production plants (car painting). The three programmes between them save more than 837 000 MWh of electricity each year – roughly equivalent to the total consumption of all households in Luxembourg.
