 (a) The Bureau of the Census classifies establishments using the 2012 North American Industry Classification System (NAICS). 

 (b) The 'Establishments' column includes those units which reported any of the five listed cogeneration technologies in use anytime in 2014, plus those units where usage of those cogeneration technologies was not ascertained.

 (c) This count includes only those establishments that reported any of the five listed cogeneration technologies in use anytime in 2014.

 (d) This count includes only those establishments that reported this cogeneration technology in use anytime in 2014.

 (e) This includes establishments that have the equipment but are currently not in use as well as those establishments that do not have or never have had the equipment during 2014.

 (a) The Bureau of the Census classifies establishments using the 2012 North American Industry Classification System (NAICS). 

 (b) The 'Establishments' column includes those units which reported any of the five listed cogeneration technologies in use anytime in 2014, plus those units where usage of those cogeneration technologies was not ascertained.

 (c) This count includes only those establishments that reported any of the five listed cogeneration technologies in use anytime in 2014.

 (d) This count includes only those establishments that reported this cogeneration technology in use anytime in 2014.

 (e) This includes establishments that have the equipment but are currently not in use as well as those establishments that do not have or never have had the equipment during 2014.

 * Estimate less than 0.5.

 W=Withheld to avoid disclosing data for individual establishments.

 Q=Withheld because Relative Standard Error is greater than 50 percent.

 NA=Not available.

 X=Not defined because RSE corresponds to a value of zero.
