Given that most buildings will last 50 years or more, retro fit is the biggest market. Retro-fit wall insulation, double glazing etc. is very expensive and would cost much more than PV with a heat pump in many locations around the world.
I think that the main advantage of efficiency measures is that they do not have the supply-demand matching problem of solar and wind. The efficiency gain is always there whenever you create the demand.

At 40 cents a watt in cost to save energy in comparison to $2-6 a watt to build solar. Efficiency first should become the new mantra for the guru’s of renewables.
