Equinor

Originally called Statoil, Equinor was established in 1972 by the Norwegian government, which retains a majority stake in the business. Headquartered in Stavanger, Norway, Equinor is primarily involved in oil and gas exploration and production, as well as energy trading, distribution and marketing, but has significantly expanded in renewable energy, particularly offshore wind. The company has expanded internationally, with direct operations in Brazil, the U.S., the U.K. and Poland, and a presence in about 25 more countries.
