1:10 a.m.: Starting Jan. 1, Ukrainians will be able to exchange up to 5 incandescent lightbulbs for the LED variety, Euromaidan Press reported.

The program envisions swapping 50 million bulbs through Ukraine’s state postal operator Ukrposhta and digital platform Diia.

According to Economy Minister Yulia Svyridenko, replacing 50 million such bulbs can save Ukraine up to 1.5 gigawatts of electricity during peak hours.

The purchase of 30 million such bulbs will be financed by the European Commission.

This measure is being undertaken in response to a deficit in Ukraine’s power grid caused by Russian missile strikes on electricity infrastructure which are estimated to affect roughly 50% of all energy facilities.
