MADISON, Wis. (AP) -- U.S. Energy Secretary Steven Chu plans to tour a wind turbine manufacturer in Milwaukee and a biomass research center on the University of Wisconsin-Madison campus on Thursday.

The Department of Energy says in a release that Chu plans to join Milwaukee Mayor Tom Barrett to tour Ingeteam's expanded manufacturing facility. Chu plans to talk about extended clean energy tax credits.

Ingeteam received nearly $1.7 million in tax credits to build the new $21 million wind turbine manufacturing facility.

Chu also plans to visit the Great Lakes Bioenergy Research Center in Madison, which is doing work to develop biofuels as alternatives to foreign oil.
