Nordex SE is a European company that designs, sells and manufactures wind turbines. The company's headquarters in the German city of Rostock while management is in Hamburg. Nordex produces at sites in Germany, Brazil, India, Mexico and Poland and, until 2022, in Spain. The main production facility is located at the headquarters in Rostock. Nordex has branches and subsidiaries in 19 countries. According to the company, it had installed wind turbines with a total capacity of around 50 GW in over 40 countries worldwide by the end of 2023. The company was founded in 1985 in Give, Denmark. Since then the company steadily grew. In 1995 Nordex was the first company to mass-produce a 1 MW turbine booster. The company Südwind Babcock-Borsig has been fully implented into Nordex on October 1, 2001. Nordex began also producing the turbines of the manufacturer Südwind, which had previously gone bankrupt. Nordex started producing turbines in the 1.5 MW class from 2001 - originally from "pro + pro Energiesysteme" developed the S70 and later the S77 - under license.

A wind turbine is a device that converts the kinetic energy of wind into electrical energy. As of 2020, hundreds of thousands of large turbines, in installations known as wind farms, were generating over 650 gigawatts of power, with 60 GW added each year. Wind turbines are an increasingly important source of intermittent renewable energy, and are used in many countries to lower energy costs and reduce reliance on fossil fuels. One study claimed that, as of 2009, wind had the "lowest relative greenhouse gas emissions, the least water consumption demands and the most favorable social impacts" compared to photovoltaic, hydro, geothermal, coal and gas energy sources.
