MacCARES Wind Turbine Projects

Utility-Scale Wind Turbine
MacCARES is currently developing a proposal for Macalester to invest in a Utility-Scale Wind Turbine in the range of 2MW. Macalester would be joining schools like Carleton, St. Olaf, Grinnell, and UM-Morris in developing cost-effective, sustainable, wind energy projects.

Urban Wind Turbine
Macalester installed a 10kw Urban Wind Turbine on-campus April 23, 2003. It is one of the very few urban wind turbines in the United States and despite its small size was an important project for studying urban renewable energy applications. The turbine and tower were donated by Xcel energy and the installation was the Class Gift of the Macalester Class of '03. It is a work in progress, as we model the limited data we have recieved and receive recommendations for improving output. This Macalester project was reported on extensively.
