The plans at Pocono call for a system comprised of a whopping 40,000 photovoltaic panels to be installed on what used to be a parking lot across the street from the track. The raceway’s president, Brandon Igdalsky, ensures that “the solar farm is expected to generate 3 megawatts once it is completed in spring 2010” and “the project is expected to cost $15 million to $17 million but [will] more than pay for itself over time.

The Nationals Stadium, the present ballpark for the Washington Nationals is here to make a difference with its eco-friendly sports. Dubbed the Nationals Park, the $611 million baseball stadium includes energy-efficient lighting, low-flow water features, and a 6300 square foot green roof that covers the concession area. Other interesting features embrace a water filtration system built directly underneath the stadium, which is made using sand filters pollutants from the water. The unique filtration system also separates water used for cleaning the ballpark from rainwater that falls on the ballpark, treating both sources before releasing all the water to the sanitary and storm water systems.
