The anti-nuclear badge “Nuclear Power? No Thanks" (Danish: Atomkraft? Nej tak.), also known as the “Smiling Sun,” is the international symbol of the anti-nuclear movement. It was ubiquitous worldwide in the late 1970s and the 1980s. BBC News reported in 2005 that few symbols had become "as instantly recognizable across the world.". Even the nuclear power industry recognized the logo's "power and success," the BBC report said. Over 20 million Smiling Sun badges were produced in 45 national and regional languages. In recent years the logo is playing a prominent role once again to raise awareness and funding for anti-nuclear groups, especially in Germany, Austria and Switzerland where opposition is growing to plans for extending operation of old nuclear reactors and constructing new ones.
The Smiling Sun logo was designed in 1975 by Danish activist Anne Lund who was part of the Danish organization OOA (Organisationen til Oplysning om Atomkraft/ Organization for Information on Nuclear Power). By posing the question: “Nuclear Power?” and providing a concise answer, “No Thanks”, the logo was intended to express dissent and—by questioning nuclear power—to stimulate dialogue. In 2011, after the Fukushima disaster, a new version was released for renewable energy, with the statement "Renewable Energy", "Yes Please" (Danish: "Vedvarende Energi? Ja tak!") on a green background with a yellow sun.
The Smiling Sun logo is an internationally registered trademark. The purpose of the trademark is to protect against alteration and prevent use by commercial and partisan political interests. Anti-nuclear groups may apply for user rights to the OOA Fund in Denmark. An online shop sells Smiling Sun merchandise in 50 different languages. The Italian political parties Federation of Green Lists, Federation of the Greens and Green Europe have licensed use of the symbol for their party electoral materials and logos.
Nuclear Power? Yes Please
A network of pro-Nuclear physicists, software developers, and environmental activists drawing inspiration from the original "Nuclear Power? No Thanks" image, but that viewed Nuclear power as part of a sustainable and green-friendly energy option into the 21st century, devised an image similar to—but with a pro-nuclear energy connotation—as part of an ongoing effort that originated in 2008.
Some commentators in support of the 'Nuclear Power? Yes Please' movement have made arguments that Nuclear power should be regulated and safely conducted, but not outright banned, "The overwhelming priority for those who make decisions about energy must be to avert climate breakdown. They need to keep the lights on, but not by sacrificing the future welfare of humanity and Earth’s living systems. It is better to light a candle than to curse the darkness. It is also better to curse the darkness than to burn your house down."
