Electric utility E.ON is one of the “Big Six” energy companies in the UK and a major power provider in Germany, where it is based. Back In 2009, Ruhrgas AG (a predecessor of E.ON) was fined €553 million for conspiring to fix prices of gas imported from Russia via the MEGAL pipeline.

Although it was historically a major fossil fuel provider, E.ON spun off its fossil fuel assets into a new company named Uniper in 2016. Subsequently it claimed to offer “100% renewable energy tariffs” to customers, despite nearly half of its energy capacity being powered by fossil fuels or nuclear power. In 2009, E.ON was accused of greenwashing for claiming to use an “integrated” technology approach after installing a few solar panels on top of the Ratcliffe-on-Soar coal-fired power station in Nottinghamshire, England. The panels were estimated to have saved 6.3 tonnes of CO2 emissions a year, equal to less than one millionth of the emissions from the power plant itself. In 2019, E.ON claimed that all its 3.3 million customers in the UK were being switched to 100 percent renewable energy plans. Good Energy, a rival electricity company, summed up the matter succinctly: "E-ON is moving its customers to a 52% renewable, 48% greenwash tariff."
