  Putin's Ukraine war has caused gas prices to skyrocket. Because of Europe's
dependence on Russian gas supplies, we all pay significantly more for heating,
involuntarily helping to fund Russia's war against Ukraine. Based on an
analysis of real-time gas price data, we present a calculation that estimates
every household's financial contribution for heating paid to Russian gas
suppliers daily at current prices - six euros per household and day. We show
ways everyone can save energy and help reduce the dependency on Russian gas
supply.
