Dear BEST society,

      Energy efficiency strategies are often hammered as ‘here and 
now’ improvements... what might be on the horizon?  As my fellow 
interns have pointed out, energy efficiency is gaining interest and 
support, prompting developments in new technologies.

      Modern lighting and heating/air-conditioning systems are 
imperative in new buildings, but now New Energy Technologies is creating 
a product to offset energy costs from the outside in.  This company is 
in the process of commercializing a transparent surface that can utilize 
light energy: the SolarWindow.  The SolarWindow technology utilizes a 
spray-on film made of tiny solar cells, replacing the metals 
traditionally used in solar tech with translucent “organic” 
compounds.  It can be powered by artificial light, direct and indirect 
sunlight, thus allowing for installation on all sides of a building.  
The New Energy Technologies website claims that the annual value of 
electricity produced by the SolarWindow [($/kWh)/yr] is potentially 
twice as productive as alternative options.

      The SolarWindow will be of most use in sizeable structures with a 
large surface areas of windows, such as skyscrapers.  There is a focus 
by New Energy Technologies to install their windows in Florida; a 
fifty-story commercial building here could generate enough electricity 
to power 100 homes and contribute to carbon emission reduction.  
However, concerns have been raised about damage from severe weather, 
since Florida is prone to hurricanes.  And what about shading from other 
buildings?  Perhaps this tech would be most efficient in upper levels.

      Buildings utilize enormous amounts of electricity.  In the pursuit 
of efficiency, we should not only look to reduce the amount of energy 
these structures expend, but seek also for methods of energy production.
