ComEd will have a presence at the ballpark during Earth Day activities. The ComEd Solar Power Station and ComEd CARE tent will be featured at Gate 5 of U.S. Cellular Field from 5-7 p.m. The ComEd "Energy Doctor" also will be on hand to provide fans with tips to help reduce energy usage and save money.

Earth Day is just one of several green initiatives the White Sox have facilitated in recent years. Other initiatives include:

• Recycling: U.S. Cellular Field recycles all plastic and paper gathered during and after each home game; recycling bins are placed throughout the ballpark. Since 1992, the White Sox and Waste Management have recycled over 570 tons of materials, including plastic cups, office paper, aluminum cans and corrugated boxes. One of the three compactors at U.S. Cellular Field is dedicated solely to recycling items.

• Conservation: A computerized "motherboard" regulates lighting inside U.S. Cellular Field, distributing power from areas where it is not being utilized to areas where it is needed, in order to conserve power.

• Transportation: Fans who choose to ride bicycles to White Sox games are provided with bicycle racks, which are monitored by security during games.

• Lights Out: On March 29, the White Sox and ISFA observed Earth Hour, shutting off electricity throughout U.S. Cellular Field - with the exception of emergency power - including the White Sox marquee board visible from the Dan Ryan Expressway.
