Major investments in energy efficiency for factories and apartment buildings could reduce by half Ukraine’s gas consumption during the 2020s,

said Vitaliy Shcherbenko, Naftogaz Director of Energy Efficiency, tells Den news site. This reduction could eliminate Ukraine’s need to import 10 bcm of gas every year, he says. Investments are needed in energy efficient boilers and insulation. Increasingly, EU and Scandinavian aid to Ukraine targets raising efficiency in Soviet-era buildings.
