Hvis Rumænien importerer omkring 14 mio. tons olieækvivalent russisk gas hvert år, betyder det f.eks., at der hvert år spildes næsten 1 mio. tons olieækvivalent som følge af utilstrækkelig isolering i boligblokke.
This means, as an example, that if Romania imports around 14 million tonnes of oil equivalent in Russian gas annually, almost one million tonnes of oil equivalent are wasted annually due to defective insulation in blocks of flats.
