As gas prices soar, many people are already stocking up on wood to heat their homes this winter, De Volkskrant reports. However, firewood is also in short supply and becoming more and more expensive. One firewood supplier, David Wunderink, told De Volkskrant he might be running out of logs in the middle of the summer due to the rush. "You notice that people are getting nervous. Normally our customers only start ordering firewood in September," Wunderink said.
