This map supplements a National Geographic Daily News article about Arkansas power plants. The EPA's new power plant regulations require Arkansas to reduce their carbon emissions by 44.5% over the next two decades, a notoriously coal-heavy state. With no formal plan to invest in clean energy, Arkansas has fired up two new coal plants in recent years and continues to receive more than half of its electricity from coal.
