1. The values shown represent 1997 averages for the Mid-Atlantic region. Energy Source (Fuel Mix) Air Emissions The amount of air pollution associated with the generation of the electricity for the Mid-Atlantic region is shown in the table at right. CO 2 is a “greenhouse gas,” which may contribute to global climate change. SO 2 and NO x released into the atmosphere react to form acid rain. NO x also react to form ground level ozone, an unhealthful component of “smog.” For additional information about this label, contact [Company name] at (800) 555-5555. Label A: Environmental Information for Standard Offer Service Provided by [Company Name] The following environmental information is for [Company Name] customers with Standard Offer Service. Standard Offer Service, which commenced on July 1, 2000, is provided to those customers who have remained with [Company Name] and who have not chosen a competitive electricity supplier. Power plants can generate electricity from a number of different fuel sources, resulting in different emissions. [Company name] will report fuel sources and emissions data to customers twice annually, allowing customers to compare data among the companies providing electricity service in Maryland. In this first report, the standardized environmental data below are regional averages only of most power plants in the Mid-Atlantic region. [Company name]-specific emissions and energy source (fuel mix) data may vary from these averages, and will be included in future semi-annual reports. Renewable energy sources subtotal: 2.8%
