    Just to be clear, installing solar photovoltaics and installing energy efficient building equipment are two very different methods of achieving the same goal. While both methods are important for reducing a buildings energy footprint, it is equally important to understand the difference between energy generation and energy efficiency.
    Here is why:
    Solar, wind, biomass, etc, produce "x" amount of energy, at a given up-front and lifecycle cost. That energy is used offset or directly power the building energy use, but does not reduce the overall building energy use. Energy efficiency does. Any smart project should start with energy efficiency upgrades (lighting, HVAC, plug loads, etc) and end with renewables. If you have to make a choice between solar panels and new lights, choose efficiency first. If you can do it all, tell the world about it, and keep up the good work.
