As the new Year arrived, the country of Ukraine shut off Russian natural gas supplies into Europe. Gas flow to Europe has halted.
A contract between Ukraine and Russia, to allow natural gas to transit through Ukraine into Europe, expired at midnight and Ukraine decided to not renew it.
Natural gas flows from Russia into Europe have now halted . . . . just as the northern hemisphere begins entering the coldest months of winter.
European countries were made aware of Ukraine's decision, and they took whatever steps they could to STORE-UP natural gas, mostly in liquified form in high pressure tanks, in advance, to get through the winter.
Some countries, though, do not have enormous storage capacity and those countries will see trouble with supplying gas for heating as February rolls around.
