On May 9, the Advanced Energy Legislation (AEL) Tracker was launched by the Advanced Energy Economy and the Colorado State University Center for the New Energy Economy. The database is designed to monitor energy bills in all 50 states. Bills are categorized by economic development, electricity generation, energy efficiency, financing, greenhouse gas emissions, infrastructure, natural gas, transportation, and other topics. According to the website, more than 2,100 bills are currently pending; 21 percent focus on clean energy development. The database plans to add legislation in Washington, DC this summer.
