Originating in 1968, the Irish Government gave renewed effort to the plans after the 1973 energy crisis. The plan envisaged one, and eventually four, nuclear power stations, but was (discreetly) dropped in the late 1970s after opposition by environmental groups, including the Wexford group the Nuclear Safety Association and others. The campaign against the proposed plant also gained some international support, including that of Petra Kelly, who gave a speech at Carnsore. One activist against the plant who later became notable was Adi Roche. Roche focused on the relief of suffering experienced by children in the wake of the 1986 Chernobyl nuclear disaster, and founded Chernobyl Children International.
