It’s a start:
A move to undo Minnesota's 17-year-old ban on new nuclear power plants easily cleared its first committee Tuesday as Republicans who run the Legislature make the proposal a priority.
Now, it’s worth noting that overturning the ban does nothing but allow Minnesota to consider nuclear energy among its options going forward.
While the Bloomberg story chooses to focus on this as a Republican issue, it isn’t really so. Appearing to give testimony before the committee were both union and business representatives, which covers a fairly large swath of a given electorate.
“Currently, the Department of Energy has more than twenty applications for construction of nuclear power plants throughout the United States. These plants would supply carbon–free, low–cost base load power for the energy grid as well as creating good paying jobs both during construction and in the operation of the plants,” said Harry Melander, President of the Minnesota Building and Construction Trades.
And a little more from Mr. Melander:
“We feel that Minnesota should lift the moratorium on nuclear power plant construction and that nuclear energy should be part of a balanced Minnesota energy policy that curbs greenhouse gas emissions and addresses global climate change.”
As you can see, he not only wants Minnesota to be able to consider building plants but he wants the building to start, and now.
And on the business side:
Bride Seifert, an energy policy specialist with the Minnesota Chamber of Commerce, argued the focus of the bill was not to immediately build a nuclear power plant but have all energy options open.
I’m not going to say it was a feast of love – certainly, there were voices raised in objection – and the bill could, of course, die on its way through other committees or in the Senate or on the governor’s desk. All true.
Because Minnesota is one of the last states that doesn’t allow nuclear power to be part of the energy discussion, this little success carries more weight than it would normally. So let’s keep an eye on it.
Over at Climate Progress, Joe Romm has up an interesting post on how to contain carbon emissions. Generally speaking, I don’t expect much from that quarter – Climate Progress is a project of the Center for American Progress, not a very nuclear-friendly venue – but Romm is usually a very interesting and engaged writer, if sometimes wrapped in too much certainty.
Humanity has only two paths forward at this point. Either we voluntarily switch to a low-carbon, low-oil, low-net water use, low-net-material use economy over the next two decades or the post-Ponzi-scheme-collapse forces us to do so circa 2030.
The Ponzi scheme is the global economy. I suspect the infrastructure investment needed to change the profile of the energy sphere would not be possible following economic collapse, but who knows? In any event, Romm uses the idea of energy wedges that might stabilize carbon before (climate not economic) disaster strikes.
And what is a wedge? In this context, it’s a very specific idea:
Physicist Professors Robert Socolow and ecologist Stephen Pacala, Co-Directors of The Carbon Mitigation Initiative at Princeton University have come up with a surprisingly clear-cut way to approaching the dilemma of global warming called stabilization wedges. The theory aims to demonstrate how global warming is a problem which can be solved by implementing today's technologies to reduce CO2 emissions.
And each technology, if it passes muster, gets a wedge or at least part of one. And what does that mean?
A wedge represents an activity that reduces emissions to the atmosphere that starts at zero today and increases to 1 giga ton per year of reduced carbon emissions in 50 years, a cumulative total of 25 giga tons of emission reduction over 50 years.
Al Gore uses wedges in An Inconvenient Truth, though, sadly, nuclear energy did not get a wedge.
But nuclear energy does get a wedge in Romm’s formulation:
- 1 [wedge] of solar photovoltaics — 2000 GW peak
- 1 wedge of nuclear power – 700 GW
- 2 [wedges] of forestry — End all tropical deforestation. Plant new trees over an area the size of the continental U.S.
This is just a selection – the full set of wedges is on the site – but electricity generation covers only some of the wedge set and other cultural changes cover the rest (not quite sure how to get consensus on the trees, but fine). That nuclear power gets its foot in the door is the surprise here.
Here’s some more from Romm on nuclear energy:
The 1 wedge of nuclear includes a half wedge of next generation nuclear post-2030. Why not more than 1 wedge? Based on a 2007 post on the Keystone report, to do this by 2050 would require adding globally, an average of 17 plants each year, while building an average of 9 plants a year to replace those that will be retired, for a total of one nuclear plant every two weeks for four decades — plus 10 Yucca Mountains to store the waste. It is also increasingly unlikely it will be among the cheaper options. And the uranium supply and non-proliferation issues for even that scale of deployment are quite serious.
That’s like the hokey-pokey. One foot in, one foot out. But at least one foot is in.
Do read the whole thing – it’s a bit complicated to grasp but well worth grasping, as stabilization wedges is an idea with currency in the climate change arena. Romm has some notably individual ideas about this, but it’s a good starting point for exploring the issue.
