Three of Switzerland's five nuclear power plants are in the canton of Aargau (Beznau I + II and Leibstadt). Additionally, the many rivers supply enough water for numerous hydroelectric power plants throughout the canton. The canton of Aargau is often called "the energy canton". A significant number of people commute into the financial center of the city of Zürich, which is just across the cantonal border. As such the per capita cantonal income (in 2005) is 49,209 CHF. Tourism is significant, particularly for the hot springs at Baden and Schinznach-Bad, the ancient castles, the landscape, and the many old museums in the canton. Hillwalking is another tourist attraction but is of only limited significance.
