Cross-cultural comparisons can prove helpful for pinpointing factors which underlie efficient energy use. This study examines differences in the attitudes of Swedes, Canadians, and Americans about energy conservation, as a vehicle for evaluating the energy policies of these nations. Although they are efficient energy users, the heavily regulated Swedes possess weaker perceptions of personal involvement and effectiveness with regard to their energy problems. Canadians seem to have a more realistic understanding of the energy situation, and are more sensitive to the economic rationale for conservation, possibly as a result of their government's conservation promotion campaigns. Implications of the findings for U.S. energy policy are discussed.
