Some local opposition to nuclear power emerged in the early 1960s,  and in the late 1960s some members of the scientific community began to express their concerns.  These concerns related to nuclear accidents , nuclear proliferation , high cost of nuclear power plants , nuclear terrorism and radioactive waste disposal .  In the early 1970s, there were large protests about a proposed nuclear power plant in Wyhl , Germany. The project was cancelled in 1975 and anti-nuclear success at Wyhl inspired opposition to nuclear power in other parts of Europe and North America.   By the mid-1970s anti-nuclear activism had moved beyond local protests and politics to gain a wider appeal and influence, and nuclear power became an issue of major public protest.  Although it lacked a single co-ordinating organization, and did not have uniform goals, the movement's efforts gained a great deal of attention.  In some countries, the nuclear power conflict "reached an intensity unprecedented in the history of technology controversies".
