Requires contractors and subcontractors performing construction work for covered renewable energy systems to use apprenticeship agreements

Reorganized the language to first establish general apprenticeship requirements for all covered renewable energy systems, then add specific requirements for thermal energy networks.

Removed the bracketed term 'thermal energy network' from the main definition and restructured to make it a separate, additional requirement rather than part of the general definition.

Added multiple sponsors to the bill introduction and included committee discharge and amendment history.
