Gene Therapy for Diseases. Gene Therapy has made important medical advances in less than two decades. Within this short time span, it has moved from the conceptual stage to technology development and laboratory research to clinical translational trials for a variety of deadly diseases. Among the most notable advancements are the following:
Duke Energy's merger with Progress Energy, completed in July 2012, created the largest electric utility in the United States. In fact, two of the three largest U.S. utilities are the result of recent mergers. Exelon, third on the list of the 10 biggest U.S. utilities, merged with Constellation Energy in March 2012. Duke will now service 7 million retail customers across six states.
Investor-owned utilities (IOUs) are private electricity and natural gas providers. California Public Utilities Commission (CPUC) oversees IOUs. Pacific Gas and Electric, San Diego Gas and Electric, and Southern California Edison comprise approximately three quarters of electricity supply in California. Publicly owned utilities (POUs) are subject to local public control and regulation. POUs are organized in various forms including municipal districts, city departments, irrigation districts, or rural cooperatives. Municipal districts may include territories outside city limits or may not even serve the entire city.
