Public Opinion on Nuclear Energy: Where is it Headed?

Ann Bisconti
The following is a guest post by Ann S. Bisconti, PhD, President, Bisconti Research, Inc.

As we await the results of the ongoing NEI Spring 2016 Public Opinion Survey on Nuclear Energy, two other surveys have raised the question: Where is public opinion about nuclear energy headed? Scientific American Plugged In, March 23, pondered the dramatically different results from questions about nuclear energy asked in polls by Gallup and the University of Texas (UT) and essentially ended puzzled, concluding that polls are faulty. But wait a minute. Both polls are accurate, and we can learn lessons about public opinion by studying them.

Gallup’s Annual Environmental Poll includes one question about nuclear energy, an NEI tracking question: “Overall, do you strongly favor, somewhat favor, somewhat oppose, or strongly oppose the use of nuclear energy as one of the ways to provide electricity in the United States.” Gallup found 44 percent in favor and 54 percent opposed in 2016, a big drop in favorability from 2015, and headlined that, for the first time, a majority of Americans oppose nuclear energy.

The UT Energy Poll asks: “Based on what you know, to what extent do you support or oppose the use of nuclear energy? (Strongly oppose, somewhat oppose, neither support nor oppose, somewhat support, or strongly support, not sure).” In contrast to Gallup, UT found that support increased from 2015 to 2016. Currently, the poll shows, 39 percent strongly or somewhat support nuclear energy, 26 percent strongly or somewhat oppose nuclear energy, and 35 percent neither support nor oppose.


Here are some lessons from these polls that are consistent with what we know from 33 years of comprehensive NEI research on public attitudes:
  • Public opinion about nuclear energy is, for the most part, not strongly held. The UT poll shows many people in the middle, and so do NEI surveys.
  • Public opinion is highly changeable and reflects a trade off people make—consciously or unconsciously—between perceptions of need and safety concerns, and the two polls illustrate how this happens. In the Gallup poll, the question about support for nuclear energy is asked after questions about hazards, triggering focus on safety concerns. In the context of questions about energy, as in the UT Energy Poll, a question about support for nuclear energy may trigger thoughts of how nuclear energy fits into the energy picture.
  • Energy concerns drive up support for nuclear energy. Gallup’s explanation for the downturn on the favorability question is primarily that energy is not currently on the public agenda. That is true. When energy is perceived to be abundant, as it is today, the perceived urgency for nuclear energy diminishes. Historically, resurgent strong support for nuclear energy coincides with periods characterized not only by electricity shortages but also by situations not especially relevant to nuclear energy such as high gasoline prices or conflict in the Middle East.
NEI’s surveys assess and track the many dimensions of attitudes toward nuclear energy, as well as the influences on these attitudes. As of 2015, U.S. public support for nuclear energy continued to be broad but not deep, and highly changeable; 68 percent in March and 64 percent in September said they favored the use of nuclear energy. A majority held middle positions, as 26 percent strongly favored nuclear energy while 15 percent strongly opposed (September).

Energy is likely to remain abundant for years, so continued support for nuclear energy will depend on a better public understanding of the urgent need not just for energy sources but for nuclear energy in particular. Our research shows that Americans want both reliable electricity and clean air. Most do not know that nuclear energy is the only source that provides both. Only nuclear energy is both a 24/7 baseload energy source like coal and natural gas and also a carbon-free energy source like solar and wind.

Challenges to building that awareness are considerable, NEI surveys showed:
  • In an open-ended question, only 10 percent of those favoring nuclear energy mentioned clean air, no pollution, or climate change as one of the reasons for their opinion (Spring 2015).
  • 67 percent of the public believed that nuclear energy releases greenhouse gases (Spring 2014)
  • 70 percent did not know that nuclear energy is the largest source of low-carbon electricity today—when, in fact, it is the largest source by far (Fall 2015).
After learning the real magnitude of nuclear energy’s contribution to the low-carbon mix, 84 percent said that nuclear energy should be important, and 50 percent said it should be very important (Fall 2015). Among those who said nuclear energy should be important after learning that information were 62 percent of those initially opposed to nuclear energy and 43 percent of those initially strongly opposed.

A Design Team Pictures the Future of Nuclear Energy

For more than 100 years, the shape and location of human settlements has been defined in large part by energy and water. Cities grew up near natural resources like hydropower, and near water for agricultural, industrial and household use.

So what would the world look like with a new generation of small nuclear reactors that could provide abundant, clean energy for electricity, water pumping and desalination and industrial processes?

Hard to say with precision, but Third Way, the non-partisan think tank, asked the design team at the Washington, D.C. office of Gensler & Associates, an architecture and interior design firm that specializes in sustainable projects like a complex that houses the NFL’s Dallas Cowboys. The talented designers saw a blooming desert and a cozy arctic village, an old urban mill re-purposed as an energy producer, a data center that integrates solar panels on its sprawling flat roofs, a naval base and a humming transit hub.

In the converted mill, high temperat…

Sneak Peek

There's an invisible force powering and propelling our way of life.
It's all around us. You can't feel it. Smell it. Or taste it.
But it's there all the same. And if you look close enough, you can see all the amazing and wondrous things it does.
It not only powers our cities and towns.
And all the high-tech things we love.
It gives us the power to invent.
To explore.
To discover.
To create advanced technologies.
This invisible force creates jobs out of thin air.
It adds billions to our economy.
It's on even when we're not.
And stays on no matter what Mother Nature throws at it.
This invisible force takes us to the outer reaches of outer space.
And to the very depths of our oceans.
It brings us together. And it makes us better.
And most importantly, it has the power to do all this in our lifetime while barely leaving a trace.
Some people might say it's kind of unbelievable.
They wonder, what is this new power that does all these extraordinary things?

Seeing the Light on Nuclear Energy

If you think that there is plenty of electricity, that the air is clean enough and that nuclear power is a just one among many options for meeting human needs, then you are probably over-focused on the United States or Western Europe. Even then, you’d be wrong.

That’s the idea at the heart of a new book, “Seeing the Light: The Case for Nuclear Power in the 21st Century,” by Scott L. Montgomery, a geoscientist and energy expert, and Thomas Graham Jr., a retired ambassador and arms control expert.


Billions of people live in energy poverty, they write, and even those who don’t, those who live in places where there is always an electric outlet or a light switch handy, we need to unmake the last 200 years of energy history, and move to non-carbon sources. Energy is integral to our lives but the authors cite a World Health Organization estimate that more than 6.5 million people die each year from air pollution.  In addition, they say, the global climate is heading for ruinous instability.
