Compare and contrast.

When then-Senator Barack Obama took the stage in Denver four years ago to accept the nomination of the Democratic Party, he delivered what many saw as a powerful and pitch-perfect speech that contained an ambitious plan to correct course after eight years of President George W. Bush. But to this reporter, sitting amongst the cheering throngs at Mile High, one point hit a decidedly sour note.

In the section on energy, which began with the understanding that the country’s economy, security and energy futures are intertwined, Obama pledged to “end our dependence on oil from the Middle East” in ten years, and also spoke of investing $150 billion in renewable energy over that same decade. But then the Democratic nominee added this:

As President, I will tap our natural gas reserves, invest in clean coal technology, and find ways to safely harness nuclear power.

And with that, at least from where I sat (politically more than physically), a soaring speech came crashing to the ground. Even four years ago, “tapping natural gas reserves” was an ominous gloss-over for dangerous drilling techniques and increased carbon emissions. “Clean coal” had already proven to be nothing better than a marketing laugh line, something the Senator from coal-producing Illinois had to say. And “find[ing] ways to safely harness nuclear power,” well, funny that, both because it, too, felt like campaign-trail noblesse oblige for some of Obama’s biggest contributors, and because it implied that a safe way to harness nuclear power was something that had not yet been found.

But there it was–what would eventually come to be known as “fracking,” plus the myth of “clean coal,” and a big nod to the moribund nuclear power industry. One, two, three strikes in Obama’s energy pitch.

Fast, uh, “forward” four years, move indoors and 2,000 miles east, and listen to what President Obama had to say about America’s energy future in his 2012 convention speech:

We’ve doubled our use of renewable energy, and thousands of Americans have jobs today building wind turbines, and long-lasting batteries. In the last year alone, we cut oil imports by one million barrels a day, more than any administration in recent history. And today, the United States of America is less dependent on foreign oil than at any time in the last two decades.

So, now you have a choice – between a strategy that reverses this progress, or one that builds on it. We’ve opened millions of new acres for oil and gas exploration in the last three years, and we’ll open more. But unlike my opponent, I will not let oil companies write this country’s energy plan, or endanger our coastlines, or collect another $4 billion in corporate welfare from our taxpayers. We’re offering a better path.

We’re offering a better path, a future where we keep investing in wind and solar and clean coal; where farmers and scientists harness new biofuels to power our cars and trucks; where construction workers build homes and factories that waste less energy; where — where we develop a hundred year supply of natural gas that’s right beneath our feet.

Yes, despite a concrete acknowledgement two minutes later that “climate change is not a hoax” and “droughts and floods and wildfires are not a joke,” the president still brags of opening “millions of new acres for oil and gas exploration in the last three years”–and then he promises to open more. And, yes, there is still a reference to the fool’s anthracite, “clean coal,” this time incongruously grouped with “wind and solar.” But notice what is not there–not in this section, not in the paragraph about the climate, not anywhere in the entire 38-minute speech.

President Obama no longer promises to “safely harness nuclear power”–that likely would have sounded like a cruel joke in a world now contaminated by the ongoing Fukushima disaster–but beyond that, he does not promise anything about nuclear power at all. There was no platitude, no carefully crafted signal to the industry that has subsidized much of Obama’s political career, no mention of nuclear power whatsoever.

That is not to say that the entire 2012 Democratic National Convention was a nuclear-free zone. A few hours before the president took the stage at the Time Warner Cable Arena, James Rogers, co-chair of the Charlotte host committee, and oh, by the way, CEO of Duke Energy, stepped to the lectern and endorsed Obama’s “all of the above” energy “strategy” (they keep using that word; I do not think it means what they think it means):

We need to work even harder toward a future of affordable, reliable and cleaner energy. That means we need to invest heavily in new zero-emission power sources, like new nuclear, wind and solar projects, as well as new technologies, like electric vehicles.

Well, if you are looking for a future of affordable, reliable and cleaner energy, you need look no further than nu–wait, what? If you are looking for those three features in an energy future, it is hard to imagine a worse option than the unsustainably expensive, chronically unreliable and dangerously dirty nuclear power plant. And, as has been discussed here many times, nuclear is not a zero-emission source, either. The massive carbon footprint of the nuclear fuel lifecycle rivals coal, and that doesn’t even consider the radioactive isotopes that facilities emit, even when they are not encountering one of their many “unusual events.”

But the CEO of the Charlotte-based energy giant probably has his eyes on a different prize. Rogers, who has been dogged by questions about a power grab after Duke’s merger with Progress Energy and his lackluster performance as fundraiser-in-chief for the DNC, sits atop a company that operates seven US nuclear power plants, and is partners in a plan to build two new AP1000 reactors in Cherokee County, South Carolina.

That last project, which is under active review by the Nuclear Regulatory Commission, awaiting a combined construction and operating license, is one of a small handful of proposed new nuclear facilities currently scrambling for financing. The South Carolina plant, along with a pair of reactors in Georgia, two slated for a different site in South Carolina, and possibly one more in Tennessee, represent what industry lobbyists like to call the “nuclear renaissance.”

But completion of any of the above is nowhere close to guaranteed, and even if some of these reactors are eventually built, none will be able to generate even one kilowatt of commercial power until years after President Obama completes his sought-after second term.

Which, if you really care about America’s energy future, is, of course, all for the better. As even James Rogers noted in his speech (and he gets props for this):

[W]e cannot lose sight of energy efficiency. Because the cleanest, most efficient power plant is the one we never have to build.

That Duke’s CEO thought to highlight efficiency is interesting. That President Obama, with his well-documented ties to the nuclear industry, chose not to even mention nuclear power is important.

In the wake of Fukushima, where hundreds of thousands of Japanese have been displaced, where tens of thousands are showing elevated radiation exposure, and where thousands of children have thyroid abnormalities, no one can be cavalier about promising a safe harnessing of the atom. And in a world where radioisotopes from the breached reactors continue to turn up in fish and farm products, not only across Japan, but across the northern hemisphere, no one can pretend this is someone else’s problem.

Obama and his campaign advisors know all this and more. They know that most industrialized democracies have chosen to shift away from nuclear since the start of the Japanese crisis. They know that populations that have been polled on the matter want to see nuclear power phased out. And they know that in a time of deficit hysteria, nuclear power plants are an economic sinkhole.

And so, on a night when the president was promised one of the largest audiences of his entire campaign, he and his team decided that 2012 was not a year to throw a bone to Obama’s nuclear backers. Obama, a consummate politician, made the decision that for his second shot at casting for the future, nuclear power is political deadweight.

This is not to say that the Obama administration has thoroughly abandoned nuclear as part of its energy plan, or even its kitchen-sink rhetoric. There is no shortage of well-researched analysis detailing where the president’s deeds have failed to match his words, and it will take more than a significant omission in one speech to turn around the federal government’s policy of protecting and propping up the nuclear industry.

But the fact remains that at a convention underwritten by the head of a large nuclear energy conglomerate, nuclear energy didn’t even rate head-of-state lip service. That in a country where the nuclear industry tries desperately to brand itself as an energy of the future, the president decided to, at least rhetorically, leave it in the past. And that in a time where apostles of the atom claim that there is a nuclear rebirth, Barack Obama decided, on one of his biggest nights, that nuclear power would be better left for dead.
