Mika Mikkonen, a resident of Tohmajärvi, Finland, experienced a dramatically high electricity bill following a prolonged cold and windless period in January. The Mikkonen family, residing in a 174-square-meter electrically heated detached house in Tohmajärvi, is now proactively preparing for the coming winter. Their household consists of five children. The recent price surge in the electricity market prompted Mika to re-evaluate their energy consumption strategy. The family’s house does have a single heat-retaining fireplace, but relies predominantly on electricity for heating. Mika is now implementing measures to mitigate future costs and ensure a more financially stable winter in Tohmajärvi.
