In January of this year, billing for used city gas and electricity began. On the 14th, at a public bathhouse in Seongbuk-gu, Seoul, the owner shows the city gas bill for January this year and last year, saying, “I was hit by a gas cost bomb.” The gas rate, which was 4,561,570 won in January of last year, jumped 95.8 percent to 8,931,000 won last month, a year following the city gas rate was raised four times due to a surge in international natural gas prices. According to the National Statistical Office, city gas rates last month rose 36.2 percent from a year ago. Surprised by the increase in heating costs last month, many households have tried to save money, but as the cold wave continues, it is expected that many households will charge higher heating costs than the previous month.
