Minding the (partisan) gap: partisan divisions in support for nuclear

Via NEI's twitter feed comes this story of a new Gallup poll on energy and environmental issues similar to that released by Pew which I dissected a few weeks ago.

For the most part, the trends are indeed quite similar - especially in the respect that public opinion on the issue of nuclear energy appears to be quite "sticky," consistently polling at a slight majority of Americans favoring its continued use (and even expansion). Unsurprisingly, support for the expanded use of nuclear energy is riven by partisan divides, with much broader numbers of Republicans favoring its expansion over Democrats.

Indeed, this partisan fissure is consistent with Pew's prior polling, with Democrats and Democratic-leaning voters strongly favoring measures including more stringent environmental regulations and more funding for alternative sources such as wind and solar, with much weaker support for the development of new nuclear or fossil fuel exploration. (Interestingly, support for new nuclear among Democrats is weaker than that of opening up federal lands for oil exploration.)

The Republican side naturally shows the inverse, with Republicans generally favoring policies to expand energy supplies (with the relative strength of support for opening up additional land for oil exploration as Democrats show for conservation and regulatory measures). A notable difference in this poll is much stronger support among Republicans for expanding nuclear energy, being the second-favorite choice among Republicans and Republican-leaners at 64% of respondents favoring, compared to 54% in the similar Pew poll.

	% in favor
	National Adults	Republicans	Democrats
Setting higher emissions and pollution standards for business and industry	70	54	85
Spending more government money on developing solar and wind power	69	51	84
Spending government money to develop alternate sources of fuel for automobiles	66	51	81
Imposing mandatory controls on carbon dioxide emissions/other greenhouse gases	65	50	82
Opening up land owned by the federal government for oil exploration	65	84	49
More strongly enforcing federal environmental regulations	64	47	80
Setting higher auto emissions standards for automobiles	62	49	76
Expanding the use of nuclear energy	52	64	41

Getting back to the issue of "stickiness" in public opinion, while support for expanding nuclear has been steadily growing among Republicans since the early 2000s, among Democrats support appears to be stuck around 40%, after briefly spiking around 2006 (incidentally, around the time of Al Gore's most famous work, An Inconvenient Truth was released).

Given the need to develop new domestic sources of energy and the general drive to phase out dirtier sources like coal, it provokes a nagging question - why such a stark partisan divide over one of the largest clean energy sources in the U.S. by share of electricity (around 20%)? Indeed, it's one thing to expect broad divisions overall (given the relative weight individuals assign to factors such as economics, waste management, safety, and so forth). And indeed, some of the split will be driven by familiarity with energy sources overall (i.e., the feasibility, not to mention practicality of providing electricity from intermittent sources at the caprice of nature). An of course, splits along other lines are perhaps more obvious manifestations of priorities - take the split over fossil exploration. But what explains nuclear?

One explanation (which I will cover in a follow-on post) is the influence of cultural factors - specifically, cultural factors which influence risk perception. There is an entire field of study devoted to this, such as the Cultural Cognition Project at the Yale Law School. Ultimately what it boils down to is that how individuals perceive risk and respond to new information is dramatically influenced by their value systems. And, perhaps unsurprisingly, the same patterns of values which tend to divide liberals and conservatives also tend to divide across issues such as the perceived risk of nuclear energy production (along with related issues, such as nuclear waste management).

However, this can cut both ways as well, a matter which should be of key interest to those committed to action on global climate change. A teaser for next time - one particularly interesting finding is those of value persuasions typically found in conservatives that if expanded use of nuclear energy is presented as a necessary solution to global climate change, these individuals become more open to evidence of the risks of climate change, as compared to greater regulatory control over industrial activity - precisely due to the issues of concordance of values. Food for thought.

Support for nuclear: Broad but shallow?

Coming just upon the heels of a recent post about public opinion on energy sources, I couldn't help but also notice this poll by Gallup which NEI points to, indicating a relatively constant support for nuclear following Fukushima. The takeaway? Despite a small uptick in opposition to nuclear following the events at Fukushima (from 38% to 40%), public support for nuclear is still high, sitting at 57% in favor or strongly in favor of nuclear energy. While Republicans (and Republican-leaners) more strongly favored nuclear energy (65% supporting vs. 34% opposed) compared to Democrats (and associated leaners - 50% support / 45% opposed), support across the Gallup poll appears to generally be broad across parties.

The starkest reported differences in opinion were between men and women - 74% of men vs. 42% for women.  Tellingly, a nearly parallel trend occurs for the perceived safety of nuclear (with 72% of men believing nuclear is safe compared to 43% of women).

Given the somewhat less sunny projections from the recent Pew poll, how does one square the difference?

Digging into the Gallup data, one observes that strong support and opposition have both historically ranged around 23% and 21%, respectively; the bulk of support and opposition has been in the more moderated "somewhat support" (33%) and "somewhat oppose" (19%). How has this changed in the events following Fukushima? Overall, not much - overall support remains constant at 57%, although one observes some erosion in self-identified "strong" support. Meanwhile, strong opposition has hardened (growing from 18% to 24% in the last polling period). 

One might square this against the Pew data in the sense that Pew specifically asked about the expansion of nuclear energy (particularly in comparison to other energy sources), while Gallup simply gauged overall public support. If one takes both trends as true, it paints a picture of public opinion over nuclear as stuck in neutral - a public which overall supports nuclear energy but is divided about its expansion in light of other perceived alternatives. 

Meanwhile, going back to the Gallup results, overall public perception of nuclear safety is relatively unchanged (57% responding that U.S. nuclear plants are safe, while 40% respond that they feel U.S. nuclear plants are unsafe). While the continued (accurate!) perception of the safety of the U.S. nuclear industry is encouraging, it speaks to the need for further outreach efforts, as well as perhaps the unique perception of nuclear compared to other sources (i.e., where constant, elevated risk - such as hazards presented by sources such as coal - is tolerated much more readily than low-frequency, highly dramatic events, even if the ultimate public health consequences are minuscule).

Given the above, clearly nuclear is not in danger of a German-style phaseout. Yet the obvious challenge for public support of nuclear - beyond simply tolerating it, but in expanding it - is in making the case to the public that nuclear is both safe and essential - the latter of which comes down to arguments both over economics and the environment.

Not all energy is fungible - and it matters

Via the NYT Green blog comes a new survey by the Pew Center indicating that a smaller majority of Americans now prefer further federal funding of research into alternative energy technologies (specifically, wind, solar, and hydrogen) as a priority over additional exploration of oil and gas supplies. If the comparison seems to be a bit of a misnomer, then you've already caught on to the idea that not all energy, as we have it now, is fungible. Generally speaking, unless you are one of the very fortunate Americans who can afford an electric vehicle (with extremely generous taxpayer support at that), what is being posed is a false dichotomy. All the windmills and solar panels in the world do extremely little to curb demand for oil (and to a lesser extent, natural gas, which may also stand in as a transportation fuel).

Being generous to the poll, one can suppose some confusion arises over the fact that natural gas has been largely responsible for electricity capacity additions within the last decade in the U.S. Still then, one wonders why nuclear energy is excluded from the choice provided.

Public support of expanded nuclear energy production (adapted from Pew)

Digging deeper into the survey, nuclear does show up; what it reveals further highlights the dichotomy illustrated above. Despite rising energy prices overall (both at the pump and in the retail electricity sector), public support clearly shows a disconnect when it comes to fossil fuel exploration versus electricity production. In general, nuclear energy is still recovering in terms of public opinion one year later following the Great Tōhoku Earthquake and tsunami and resulting nuclear crisis at Fukushima.

Public support for off-shore oil drilling, from Pew

What is perhaps revealing is to contrast this to the trend in public opinion on offshore oil drilling following the Deepwater Horizon blowout and massive spill in the Gulf of Mexico - something much closer to home. Unlike nuclear energy, public opinion has generally settled back into its prior setting (enjoying broad majority support) within less than two years, with large majorities favoring expanded offshore oil drilling. While favorable opinion on nuclear expansion appears to recovering, it is still unlikely to achieve the broad support that offshore oil exploration has - again, despite the very visible risks of the latter.

Perhaps also noteworthy is the relative "stickiness" of public opinion - one observes that following a high-profile event (e.g., Deep Water Horizon or Fukushima), public opinion eventually gravitates back to its historical average, implying relatively firmly entrenched opinion with a handful of the public being swayed by major events.

Public support for increased federal funding for alternative
energy research, from Pew

For comparison, Pew also evaluated public opinion of increased financing for alternative energy sources, including solar, wind, and hydrogen. Interestingly, public support for such increased financing has been on a slow decline; thus, in spite of the lede in the New York Times blog that this is somehow a newly emerging phenomenon compared to conventional sources, it is a process which appears to have been dragging on for some time. Indeed, the trend appears to have begun well before high-profile events such as the Solyndra bankruptcy and resulting scandal; while public support slowly continues to drop afterwards, the decline began well before this and continues steadily afterwards. It is difficult to speculate what one may take away from this other than the fact that if the Republican nomination fight is any sign, Americans are notoriously fickle, constantly in search of an appealing hypothetical alternative which simply does not exist.

Why the quicker"snap back" in public opinion (or faster-acting amnesia, if you prefer) for oil and gas exploration, in particular? A likely culprit is the higher visibility of rising fuel prices (directly connected with the price of oil); particularly strong is the correlation between public support for oil and gas exploration and the price at the pump. 

Average retail electricity prices, from EIA

Retail prices for electricity have also been on the rise, but such a rise has been much more of a slow creep; with the average rising slowly over a matter of months rather than weeks. Plausibly, electricity consumption is perhaps seen as something consumers can exert some degree of influence over, be it through conservation or efficiency improvements, while demand for gasoline is relatively fixed (at least with respect to workplace commuting).

Meanwhile, yet another interesting artifact comes out of the Pew poll: a breakdown of support for various energy policies by self-identified party, with some of the highlights as follows:

	% in favor
	Rep	Dem	Ind
Allowing more oil & gas drilling in U.S. waters	89	50	64
Giving tax cuts for oil & gas exploration	61	38	42
Promoting the increased use of nuclear power	54	37	45
Requiring better fuel efficiency for vehicles	67	88	77
Spending more on mass transit	52	74	67
More federal funding for alt. energy research	52	81	70

What the above data puts to lie is the myth that members of either major political party are interested in an "all-of-the-above" energy strategy, something frequently invoked as a toll to political correctness (by countless nuclear advocates included) but not reflecting anyone's actual opinions. Indeed, among self-identified Republicans, while a much larger number favor nuclear energy expansion compared to Democrats, it is still a far less popular option than most scenarios involving either the development of additional fossil fuel resources or extension of existing supplies (i.e., fuel efficiency mandates). With respect to Democrats, overwhelming majorities seem to place their faith in measures such as conservation (including vehicle efficiency) and alternative energy research, particularly compared to the use of nuclear energy (again, issues of numeracy be damned). Only self-described independents might be considered to favor an "all of the above" strategy, although their support of such is divided at best.

In other words, despite the popularity of declaring favor for an "all-of-the-above" energy strategy, such a mantra is typically invoked simply as a cover-all in order to push forward an individual's energy priorities without having to engage in inconvenient discussions like practicality, cost, or environmental impacts. And again - this is something which occurs across the board - a token statement given which if the above is any indication, few actually believe (at least with any fervor).

What is perhaps most evident from the above is sharp evidence for the hypothesis that in the political conversation over energy, Americans are talking past one another. Again - given the fact that very little oil is burned directly to produce electricity, most of the conversation on fossil fuels comes down to energy for transportation, with natural gas coming along for the ride in the sense that it may conceivably occupy both sectors. Meanwhile, absent dramatic advances in battery technology, renewables show nearly zero intersection with the transportation sector.

Meanwhile, the lesson in this for advocates of nuclear, both looking at the historic trend in public opinion of oil drilling compared to nuclear energy as well as divisions among party lines is that in order for nuclear to command strong majorities of public support, the issue of ever-rising electricity prices (rising in tandem with global demand for overall energy resources, including coal and natural gas) must be continuously hammered, along with nuclear energy's role in providing affordable, base load electricity. The issue of electricity prices can and does motivate groups - and indeed, sometimes in the wrong way. An example would be the AARP's opposition to Iowa's recent legislative action toward allowing construction-in-progress financing of small modular reactors. The reason? Concerns over electricity prices for those living on fixed incomes. Again, despite the fact that the conclusion is logically perverse in this case, the connection is quite clear.

So what does all of this come down to? Ultimately, it reinforces the issue of fungibility in energy. For nuclear to enjoy the same resilience as fossil fuel sources with public opinion, it must also share the same perception of indispensability. Right now, nuclear is viewed as a fungible energy source - again, one can refer back to the way in which both Republicans and Democrats appear to be making a mental substitution (natural gas or renewables, respectively), thus making nuclear expansion appear to be an "optional" energy strategy for a resource (and carbon)-constrained energy future. Until advocates drive home the essential nature of nuclear energy production with respect to both future energy prices and the environment (i.e., demonstrating that nuclear energy is not so easily substituted without unacceptable economic and environmental trade-offs), it is likely support for nuclear will languish at its historic value near 50%, with sharp and persistent divisions among partisan lines.
