In an effort to reduce energy usage by 25 percent in its restaurants, McDonald's opened a prototype restaurant in Chicago in 2009, intending to use the model in its other restaurants throughout the world. Building on past efforts, specifically a restaurant it opened in Sweden in 2000 that was the first to incorporate green ideas, McDonald's designed the Chicago site to save energy by managing storm water, using skylights for more natural lighting, and installing partitions and tabletops made from recycled goods, among other measures.
