Stephanie Kirchner's journey to work has gotten longer but, she says, cheaper: she has left her SUV at home and switched to real horse power. Stud farm owner and horse trainer Kirchner says she decided "it can't go on like this" after fuel prices jumped following the Russian invasion of Ukraine. "Since I also suspected hay harvesting and everything else will become much, much more expensive, we said --we have to save a little money,'" she said. So she has switched to traveling the roughly 6 kilometers (roughly 3.5 miles) from her home in western Germany by horse-drawn carriage. While it turns a one-way trip from 10-15 minutes into an hour, Kirchner estimates is saves her about â‚¬250 (about $264 US) per month.
