Before the war, Russia supplied between 40 and 50 per cent of natural gas imported by the EU.
Residential gas and electricity prices have surged as a result.
This winter, temperatures are expected not to be extreme either way, compared to recent decades, and it is also expected to be a typical flu season.
The model found that, if weather is average, a 10 per cent increase in electricity prices is linked to a rise in deaths of 0.6 per cent.
Italy would suffer most extra deaths.
Results showed that Italy, which has an older population and particularly high electricity prices, would suffer the most extra deaths.
It also found that Estonia and Finland would suffer a large rate of extra deaths this winter.
Britain and France, having introduced price caps, would fare better.
And, in Austria, which imposed a very generous price cap, winter deaths were expected to go down.
The model for the effects of high energy costs did not include Ukraine.
It noted that, because of Russian attacks on infrastructure, Ukraine would suffer more extra civilian deaths than any of the countries in the model.
