Petrobras and Equinor are considering installing up to seven offshore wind farms in Brazil with the potential to generate up to 14.5GW.

The Brazilian and Norwegian oil & gas giants have signed a letter of intent to evaluate the technical, economic, and environmental feasibility of the sites, which could lead to investments of about $70bn.

The agreement comes as Latin America's largest economy is trying to recreate offshore the success of its onshore wind farms.
