Nästan pinsamt tjat.
Men när det börjar mörkna på hösten är det väl dags att ta upp detta med energisparlampor igen (CFL, Kompaktlysrör). Och att fråga oss själva (vi effektiviseringsnördar) vad vi gör för fel när glödlampan fortfarande dominerar i hemmen som ljuskälla. Avkastningen på investeringen i energisparlampor är ju bedövande och slår alla aktieklipp med råge. 100% minimum!
