Energy is a peer-reviewed academic journal covering research on energy engineering that was established in 1976. It is published by Elsevier and the editor-in-chief is Henrik Lund (Aalborg University). According to the Journal Citation Reports, the journal has a 2013 impact factor of 4.159, ranking it 13th out of 83 journals in the category "Energy & Fuels" and second out of 55 journals in "Thermodynamics".
In signal processing, the energy of a continuous-time signal x(t) is defined as
the energy of a discrete-time signal x(t) is defined as
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.
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.

A village in a distand land
Calling thier name
The spirit of the jemba drum
Guiding thier way
Into thier dreams the ship set sail
Bound for far away
In the search for the shores of her bay
Cape Town
Ohhhh, cape town
Rode the liberation wave
Away from the tide
Searching for a better day
Babies trapped to thier sound
Not knowing where the ship would sail
Faith was all they had
And they finally found thier way home
To the land of love and freedom
To the place where we belong
Truth and reconciliation
Is what's going on
It's a time for celebration
The night has just begun
So dance in the light of the land
That they call cape town
MUSIC.....
It's the land of love and freedom
To the place where we belong
Truth and reconciliation
It's what's going on
It's a time for celebration
The night has just begun
So dance in the light of the land of the sun
To the land of love and freedom
To the place where we belong
Truth and reconciliation
Is what's going on
It's a time for celebration
The night has just begun
So dance in the light of the land
That they call cape town
