GenOn Energy
GenOn Energy, Inc., based in Houston, Texas, United States, was an energy company that provided electricity to wholesale customers in the United States. The company was one of the largest independent power producers in the nation with more than 14,000 megawatts of power generation capacity across the United States using natural gas, fuel oil and coal. GenOn Energy is headquartered in the Reliant Energy Plaza in Downtown Houston. The company, formerly known as RRI Energy, acquired Mirant on December 3, 2010. The corporate names and logos of both RRI Energy and Mirant were retired.
NRG Energy completed its acquisition of GenOn Energy in December 2012 for $1.7 billion. GenOn's stock ceased trading and was exchanged for NRG stock.
History
The company was originally known as Houston Industries (NYSE: HOU), and Houston Lighting & Power was its subsidiary. In August 1996 HI closed on a merger with NorAm Energy Corp, a natural gas utility. The combined company, as of 1997, had assets of $18 billion and annual revenues of about $9 billion. By November 1997 there was a published report stating that the company wished to acquire Central & South West Corp. HI declined to comment.

Relationship to energy in physics
Energy in this context is not, strictly speaking, the same as the conventional notion of energy in physics and the other sciences. The two concepts are, however, closely related, and it is possible to convert from one to the other:
For example, if x(t) represents the potential (in volts) of an electrical signal propagating across a transmission line, then Z would represent the characteristic impedance (in ohms) of the transmission line. The units of measure for the signal energy would appear as volt2·seconds, which is not dimensionally correct for energy in the sense of the physical sciences. After dividing by Z, however, the dimensions of E would become volt2·seconds per ohm, which is equivalent to joules, the SI unit for energy as defined in the physical sciences.

Seven Year Itch (Collective Soul album)
On September 18, 2001, Collective Soul released their greatest hits compilation Seven Year Itch: Greatest Hits, 1994-2001 (stylized as 7even Year Itch). The compilation includes songs recorded from 1994 to 2001 and included two new tracks; "Next Homecoming" and "Energy". Seven Year Itch received decent reviews and was relatively successful It sold 225,000 copies in the first year after its release and reached number fifty on the Billboard 200; in Canada, it reached number nine on its albums chart and went platinum. All the songs in Seven Year Itch had charted in the US on the Billboard Hot 100, Mainstream Rock Tracks, or the Modern Rock Tracks chart, except for "Energy", which debuted in this compilation.
The compilation has sold over 500,000 copies. It saw a resurgence in sales after Collective Soul began putting out albums on their own independent label, El Music Group, beginning in 2004.
Seven Year Itch was the last album Collective Soul released through Atlantic Records and their last album to feature guitarist Ross Childress, who had been with the band since its 1993/1994 debut.
