Detailed Data Shows Complex and Shifting Attitudes Toward Nuclear Power in Weeks Following Fukushima Nuclear Incident

Infegy, provider of the industry’s most intelligent social media monitoring and analytics platform, today released results of social media and web analysis of public global sentiment towards nuclear energy over the month of March. The insight shows dramatic shifts and complex attitudes in the public’s perception of nuclear energy before and after a massive 9.0 earthquake hit Japan and caused ongoing problems at the Fukushima Daiichi power plant on March 11, 2011.

Social Radar’s analysis of over 40 million online conversations shows the public’s perception of nuclear energy was overwhelmingly positive on and before March 10, taking a sharp negative dive after the earthquake and problems began arising at the Fukushima Daiichi power plant. Analysis shows that:

  •     The majority of the public, 76%, held a positive perception of nuclear energy up until March 10.
  •     As of March 13, sentiment and perception had dramatically reversed, with 62% of online conversations surrounding “nuclear energy” containing negative sentiment and reaction that day alone, and remaining negative for the next four days.
  •     After March 17, public sentiment towards nuclear energy became more mixed, revealing complex and conflicting feelings and attitudes toward nuclear energy with a near 50/50 split of negative vs. positive perception.
  •     As news of conditions at the Fukushima Daiichi power plant worsened, negative sentiment grew, though positive sentiment regained the lead in conversations by the end of the month.

  •     On March 31, mentions were 300 times higher than at the beginning of the month, and over 1,000 times higher than one year ago.
  •     Positive and Negative sentiment towards nuclear energy within those conversations traded popularity once, on March 4, before the earthquake in Japan, and then multiple times since March 11, showing dynamic public response to the disaster.
