OPINION: Russian attacks on Ukraine’s infrastructure has provided a dramatic reminder of the critical importance of the energy industry to economic and human wellbeing.

More than a million households were said to be left without electricity after widespread missile and drone attacks on facilities across the country.

One third of Ukraine’s power generation stations have been hit or put out of action in what is thought to be Russian retaliation for setbacks on the battlefield.

The missile strikes follow threats to Ukraine nuclear plants and the unexplained bombing of the Nord Stream 1 and 2 pipelines, which link Siberian gas fields with Germany.
