TOKYO, Jan. 5 — In many countries, higher oil prices have hurt pocketbooks and led to worries about economic slowdowns. But here in Japan, Kiminobu Kimura, an architect, says he has not felt the pinch. In fact, his monthly energy bill is lower than a year ago.

A reason is his new home fuel cell, a machine as large and quiet as a filing cabinet that sits in front of his house and turns hydrogen into electricity and cold water into hot — at a fraction of regular utility costs. But even with the futuristic device, which is available for now only in Japan, Mr. Kimura has not let up on the other shortcuts that leave him unscathed by last year’s oil squeeze.
