"'Supermajor' has long been the term used to describe the world's largest oil companies. Increasingly, it is coming to define the globe's biggest producers of wind and solar power.
Large-scale renewable energy developers now boast valuations greater than the behemoths of the oil and gas industry.
NextEra Energy Inc., a Florida-based power company and the world's largest generator of wind and solar electricity, is now worth $138 billion. That's more than the likes of Royal Dutch Shell PLC ($112 billion), BP PLC ($71 billion) and ConocoPhillips ($40.1 billion)."
