Green PA Hire

Environmental concerns have risen in profile in the last few years, and few companies or individuals can choose to ignore these completely.  I've read people suggesting that hiring the most efficient speakers (i.e. those that produce the most sound for a given power input) is the most environmentally friendly approach.  This suggestion does not however take into account that efficient boxes (often point source) can sometimes be the heaviest and largest.  Transportation is surely a massive factor if green concerns are paramount.
Line array system can offer a greener option as less equipment is typically required to cover the same number of people.  Of course a lot depends on the exact set-up in question - from an environmental perceptive, less is more, but from a rock'n'roll perspective, MORE is more!

A 10KW PA system will only use an average of around 2000W, with odd peaks above this.  This of course depends on how hard the system is driven.  But moving this equipment on a 200 mile round trip does have an environmental impact.
The solution, at least in some instances, may be to use firms local to the event where possible.
