In 1929, municipalities and the Rhine Province combined their shareholdings into a holding company Kommunale Aufnahmegruppe für Aktien GmbH.
[6] In 1922, it expanded its coal business by acquiring three anthracite mines in Essen and a majority stake in the lignite company Braunkohlen- und Briketwerke Roddergrube AG.

The then First Mayor of Essen, Just Dillgardt, who was also second chairman of RWE's supervisory board, had reported Ricken to the state police.
Wilhelm Ricken was then arrested on 20 October 1943, and sentenced to death on 8 March 1944, by the Volksgerichtshof (People's Court), partly because of his statement that "the war would end like 1918".
Until its closure in 1985, this plant would serve as a source of important findings which supported the design and operation of commercial nuclear reactors.

RWE has long been among the top targets of climate activists, in part as a result of a long-running, high-profile battle to preserve a forest in western Germany that is threatened by the planned expansion of one of the group's coal mines.
[43] In October 2018, an estimated 50,000 protesters turned out against the company's planned continued forest clear-cutting for its open-pit coal mine expansion while a court order delayed the process until at least late 2020, to explore if it violated EU environmental regulations.
