A new age of energy company

In addition to leading the ranking in the U.S., NextEra Energy was also the leading electric utility worldwide in terms of market value as of that month. Along with companies such as Iberdrola, Enel, Orsted, and EDF Energy, NextEra Energy is part of a new generation of energy giants nicknamed green supermajors. With large investments in renewable electricity capacity, these utilities have seen their market value soar recently, challenging established energy companies operating in the oil sector such as Chevron and Shell.
