If you're looking for examples of how companies are using Microsoft technology to help with environmental sustainability, visit the Microsoft Case Studies site. On the Case Studies home page, go to the “Business Need” tab then select “Environmental Sustainability”.  A new page will appear with a variety of relevant case studies that describe how Microsoft products help customers to reduce their environmental impact. For instance, the latest case study discusses how Eidsiva Energi, a Norwegian utility company, upgraded to Windows 7 and is using the power management features to help reduce energy and costs.
