Green tags are purchased as a surcharge to your energy bill and are used to help offset costs associated with renewable energy sources and help cut back on the power required from traditional fossil-fired plants.  The surcharge is measured through meter readings.

White tags are created through actual reductions in energy usage that are measured through software and control techniques.
    Remember, too, that the IRS is offering incentives for becoming more green.  Go to
www.energy.gov/taxbreaks.htm to find information about federal tax breaks.  Each state also offers its own incentives.  www.dsireusa.org gives a rundown on what states and some localities are offering.
