Happy Earth Day!

The Washington Post celebrates Earth Day as it might, with an editorial about the failure to make a cap-and-trade regime work in the European Union. Let’s let that slide off the side a bit, though, and focus on this paragraph:

Germany is irrationally shutting its nuclear power plants — which produce lots of steady, reliable electricity and no carbon dioxide emissions — and promising that renewables will somehow pick up the slack. Perversely, that approach has led power companies to ramp up coal burning, the dirtiest fossil fuel, in a country that has also lavished its public money on the solar industry. Spain, too, has over-invested in expensive renewables. To its credit, France hasn’t decided to shutter its nuclear plants, but it is one of many countries that refuse to open up natural gas reserves, a resource that could help wean the continent off coal.

This is actually pretty rough on renewable energy, more so than one usually sees from the Post. It’s also correct, especially as regards Germany. Irrational doesn’t begin to say it.

The gist of the editorial is that the United States, which seemed a few years ago way behind Europe on the issue of climate changes, is now way ahead. The ramped-up use of natural gas gets a lot of the credit for that, but the Post doesn’t ignore that nuclear energy also helps in the effort to displace carbon emissions. One can reasonably expect this displacement to accelerate after V.C. Summer and Plant Vogtle open two new reactors each over the next eight years or so.

Only a few years ago, it would have been outrageous to claim that the United States would ever be on a better emissions trajectory than Europe. Yet it is now burning less coal even as Europe burns more. That partially reflects the fact that the United States is only now taking steps mandating greater fuel efficiency for cars. But it is also the result of a practical embrace of natural gas and the continued use of nuclear power.

If electric/hybrid cars take off, the sky, so to speak, is the limit. More nuclear energy to power them wouldn’t go amiss either.


The Heritage Foundation’s Jack Spencer also takes a crack at Earth Day by reminding us that the nuclear project is embedded quite deeply in the principles that motivate those that want a cleaner plant.

More so than any other energy source, nuclear technology makes possible the production of massive amounts of clean, reliable and affordable power. In fact, nuclear power — which now provides 20 percent of our nation’s energy — does more to preserve Senator Nelson’s prized environmental resources (land, water and air) than any other energy source, “green” or otherwise.

The Nelson mentioned is not Sen. Ben Nelson (R-Neb.), by the way, but Sen. Gaylord Nelson (D-WI), who helped found Earth Day in the U.S. in 1970, rooted in a UNESCO effort to create an Earth Day on the first day of Spring. Nelson won the Presidential Medal of Freedom for this and it serves as his primary legacy. You can watch the Senator speak on the first Earth Day here. Nelson died in 2005.

Spencer gets into some more specific points that are startling when put so plainly:

A traditional nuclear power plant takes up only a few hundred acres. New reactor technologies are even less land-intensive. The power produced by a single nuclear reactor is often enough to keep the lights on for millions of people. Wind and solar, on the other hand, can take thousands or tens of thousands of acres to produce the same amounts of energy. For instance, in order to generate the same amount of power as a single nuclear reactor, wind turbines would have to cover the entire area of the Great Smoky Mountains — that’s over 900 miles.

Also add in that wind energy still has a challenging capacity factor issue compared to nuclear energy (or any baseload energy) – it can deliver about 40 to 50 percent of its total potential capacity while nuclear energy is around 90 to 95 percent (over 100 percent if you count uprates). So make that two Great Smoky Mountains.

Now, let’s concede that energy choices are more complex than either Spencer – or I – are allowing. Capacity factor and land use are important but not necessarily determinative. Wind farms are less expensive than nuclear energy facilities and benefit from the approval of the environmental movement, which gives them a exceptionally benign profile. That may not give enough of the whole story, though, which is what Spencer is demonstrating – and doing an exceptionally good job of it – reminding everyone that Earth Day achieves some of its goals via nuclear energy.

In conclusion, Happy Earth Day. There are a lot of sites out there to help you with ideas of how you can make your segment of the planet earthier, but why not start with the Earth Day Network and work outward from there.

The people in Vermont are beginning to realize that wind farms don't have a benign profile. They're suddenly horrified to see many of their picturesque ridgelines and mountaintops lopped off to make room for the industrial-sized wind turbines. All that for an energy source that has maybe a 30% capacity factor. Yet they seemingly go after an utterly benign energy source that uses a few hundred acres nestled nearly out of sight, with a 90+% capacity factor (Vermont Yankee).

Nicely done, NEI! Keep up these great blog posts.

A Billion Miles Under Nuclear Energy (Updated)

And the winner is…Cassini-Huygens, in triple overtime.

The spaceship conceived in 1982 and launched fifteen years later, will crash into Saturn on September 15, after a mission of 19 years and 355 days, powered by the audacity and technical prowess of scientists and engineers from 17 different countries, and 72 pounds of plutonium.

The mission was so successful that it was extended three times; it was intended to last only until 2008.

Since April, the ship has been continuing to orbit Saturn, swinging through the 1,500-mile gap between the planet and its rings, an area not previously explored. This is a good maneuver for a spaceship nearing the end of its mission, since colliding with a rock could end things early.

Cassini will dive a little deeper and plunge toward Saturn’s surface, where it will transmit data until it burns up in the planet’s atmosphere. The radio signal will arrive here early Friday morning, Eastern time. A NASA video explains.

In the years since Cassini has launc…

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?

Missing the Point about Pennsylvania’s Nuclear Plants

A group that includes oil and gas companies in Pennsylvania released a study on Monday that argues that twenty years ago, planners underestimated the value of nuclear plants in the electricity market. According to the group, that means the state should now let the plants close.


The question confronting the state now isn’t what the companies that owned the reactors at the time of de-regulation got or didn’t get. It’s not a question of whether they were profitable in the '80s, '90s and '00s. It’s about now. Business works by looking at the present and making projections about the future.

Is losing the nuclear plants what’s best for the state going forward?

Pennsylvania needs clean air. It needs jobs. And it needs protection against over-reliance on a single fuel source.

What the reactors need is recognition of all the value they provide. The electricity market is depressed, and if electricity is treated as a simple commodity, with no regard for its benefit to clean air o…
