Nuclear debate

Lovins v. Richter

Posted by David Roberts at 3:27 PM on 08 Jun 2007

Read more about: energy | climate | nuclear power | Amory Lovins

Energy guru Amory Lovins and Nobel Prize-winning physicist Dr. Burton Richter face off, mano a mano, debating the merits of nuclear energy for addressing the climate crisis. MongaBay offers a blow-by-blow account. No one will be shocked to hear that I would call the bout for Lovins, though it was far from a TKO.

Cogen?!?

Cogen is a small-step-forward technology.  You're still burning fossil fuels for heat, you're just generating some electricity while doing it.  I also think the concept that efficiency can be responsible for 75% of carbon reduction is just silly.  I think Amory at least forgot to factor increased demand.

The land of unreality

There are two seperate bunches of maniacs in the Global Warming debate.  The global warming skeptics, and the anti-nuk environmentalists,  It is hard to tell which group is more insane, or which group constitutes a greater danger to life on this earth.  My money is on the anti-nuk environmentalists who will protect the coal lobby more effectively than the deniers will ever do.

Nuclear power is the only proven technology that can replace coal fired steam plants, despite all the anti-nuk claim about wind and bat guano saving the planet.      

Charles Barton

Nuclear power is declining???

National Academy of Science says the US can displace 19% of new GHG from electricity by wind (+solar is about the same) by 2020-- it will be a while before these can displace current GHG emissions from fossil fuels. The US is a wind- and solar-rich country (compared to Germany and most of Europe).

Whenever Lovins says we can solve it without nuclear, I wonder what it is.

From the discussion:

Lovins said that micropower (i.e. distributed energy generation) now accounts for one-sixth of world power, surpassing nuclear as a source of electricity for the first time in 2006. He noted that in 2005 micropower added four times as much output and eleven times as much capacity as nuclear added.

Micropower is, of course, mostly fossil fuel, so I wonder if Lovins is addressing the incredible death rate from direct pollution and climate change that accompanies fossil fuel, or is more concerned about the size of the plant.

Lovins often uses different facts than do other analysts. China added 100 GW in coal power in 2006, much of it micropower. Then he talks about 75% efficiency and 25% demand and extols China's focus on efficiency.

Why will carbon pricing penalize nuclear power plants? Why would  it benefit solar over nuclear?

One question I have every time I read Lovins: for wind to supply more than 10 - 20% of the power, we need to upgrade the grid incredibly to schlep wind power from all over -- hundreds of miles at least. The grid will be much more under central control than it is now. Why will using wind power protect the grid from power failure when A) the grid will be much more centralized, and B) intermittents like wind are much more likely to cause grid failure? (Because if power out doesn't equal power in, the grid can crash, and forecasting power in from wind power is still not all that reliable.)

Lovins says that investment in nuclear power in India is flat? Perhaps, but why the special deal with India so that it can acquire nuclear power? Actually, I frequently hear from people who are anti-nuclear power that nuclear power is dead, can't make it in the market place, etc. If I go to an industry site, I see that China intends to add 300 GW of nuclear power this half century (triple the current US amount), and that they are not alone.

Well, Lovins will always be able to use his 2005 micropower numbers, even as the situation continues to change for nuclear.

Nuclear isn't that big

Nuclear isn't that big on a world scale.

Low-carbon lightning rods

AB Lovins attracts nuclear defenses through misunderstandings of his messages.  Lovins is not an antinuclear dirty hippie.  RMI has big energy consulting contracts.  He sees the business benefits of smart energy thinking.  

Whether or not one is for or against nuclear, it is clear that as carbon market investments grow, investors will seek low-risk and low-cost projects.  That means that as carbon prices go up, renewables will benefit in the private sector, while the nuclear industry's best chances come from heavy government subsidies and mandates.  The long risks of nuclear investments are too high in a fast free market. The energy market is so big that subsidies of expensive big energy are not sustainable.

Efficiency from new infrastructure can get us 75% of the 80% carbon reduction (60% energy reduction).  Supply of 25% of the reduction is just 20% of current fossil supply (plus population growth), not a lot, and can be delivered with known low-carbon technologies.  High voltage DC lines will smooth out demand and supply fluctuations.  Low-carbon energy supply (not just electricity) should be diversified and reliable.


Supply and demand, again

GreyFlcn wrote: Nuclear isn't that big

Yes. The presence of today's dirt-cheap oil means it does not yet make economic sense to produce oil/gasoline/ethanol synthetically from nuclear energy.


Way too expensive

Nuclear costs.  Add the 6 dollars per watt basic construction costs to another 6 bucks per watt waste disposal and decommisioning.  Add another 2 for insurance.  Add how much for groundwater contamination from already leaking facilities?  it can't be cleaned up either.  

How much is groundwater worth?  how much to add for even one accident at a used fuel rod storage pool that would release 7 to 18 times the radiation of chernobyl, contaminating whole regions?

Basically the costs from nuclear power are so high they are incalculable.  How much are the additional deaths from cancer going to cost, from strontium 90, plutonium, tritium and more all leaking as we blog in numerous locations known, unknown, and known but undisclosed by corrupt nuclear cvontractor/government collusion for big $$$?

Solar pV is cheaper than that right now.  And as solar PV and wind are mass produced, watch the already cheapest power source wind drop in price.  So will solar.  Concentrating solar uses 10% of the PV cells for 3 times the power output already.

Solar cogeneration collects heat as well as electric power.

Biogas could provide all the distributed backup the grid needs, and then there is pumped hydro storage.  Gar calculates 50 square miles of resevoir will do the entire backup job for a 100% wind powered grid.

Amory needs to read this blog.  His arguments would be much sharper.

Do you mean that I could have a 2-kilowatt concentrating solar-photovoltaic system with battery-back-up installed on my property for $4,000? That is interesting since, in 2001, Kenneth Adelman spent $360,000 ($421,000 in 2007 dollars) for his 27-kilowatt system.

Nuclear costs

Of course mass producing reactor units will decrease per unit costs, as will use of recent design concepts like passive safety features.  Recent estimates of the cost of electricity generated at new nuclear plants are that it will be less than the cost of coal generated electricity.  It will certainly be less than the cost of coal generated electricity if you add the social cost of uaing a carbon based fuel.    

The capital costs of using either wind or solar power increases with increased peek load penetration, while per unit capital costs of each reactor generator decreases with each added unit.    This was demonstrated in France when the French Government built 34 identical power plants, creating significant per unit savings.  

In addition VI generation reactors promise enormous construction savings, because they are much safer than current reactor designs.    They are also cheaper to operate than coal fired plants, or generation IV reactors.  Thus the outlook is for the cost of reactor generated power already competative with coal, to have a significantly greater coast advantage in the future.  If the true social costs of coal fired steam plants is factored in, reactor power is far cheaper.    

The demand for added generating capacity in India and China during the next 60 years are enormous,  Current plans call for meeting those needs primarily through use of Coal.  For this to happen would be a tremendous disaster.  This enormous disaster is the train wreck which the anti-Nuk nut cases are trying to push us towards.

Nuclear costs II

Amazngdrx claims "6 dollars per watt basic construction costs" for reactor power.  Where did this claim come from?  Recent Chines raactor costs have run from a reported $1500 per KW to $1300 per KW. Westinghouse claims its Advanced PWR reactor, the AP1000, will cost $1400 per KW for the first reactor and fall to USD $1000 per KW in mass production.  Even these costs could fall dramatically with generation VI reactors.  
Duke Energy Corp. recently quoted a $1.8 billion cost to build a single 800-megawatt coal-fired power unit.

What the anti-nuks won't tell you is that 150 coal fired geenerating plants have been proposed nationwide.  In Texas we fought back a plan to build 18 coal fired plants. We have got to go to the nuclear alternative to coal now.    

Once again the anti-Nuks are peddling ignorance.  

Charles Barton

Last nukes built

The last plants built in the US were 6 bucks per watt.  That's total construction cost, turn key.

The lower estimates touted here are just for the actual reactor parts.  Maybe in russia nukes would be cheaper?  We'll find out, pooty poot is a-building floating chernobyls on barges right now, with duuhbya's enthusiastic support of course!  Coming to beachfront location near you soon!?!  

Who wants a KGB mob power company parked offshore near them?  Everyone!!!  Obviously they will be much less objectional than Cape wind for instance.

Unless government could outlaw NIMBY lawsuits (negating the rights outlined in the US constitution, which the administration is working on) the cost of domestic US nukes will be more like 10 bucks per watt now.  A lot of inflation has transpired since the last plants were completed too.  

Start a nuke today and 10 years from now you might generate some power?  It's a slow process.  Too slow to stop GHG climate disaster.  For that 1000s of plants would be needed.

Bush offered to pick up the tab for delays from nIMBY suits with taxpayer dollars (borrowed from china).  He's a generous primate!  Ooo oo eee eee ahh ahh.

As far as 6 bucks for waste disposal and decommisioning that maybe a low estimate as well.  Of course pooty poot's reactors will be dumped in the ocean after 20 years, no problem!

Show my calculations buddy?  No thanks.  Work on that yourself, would you?  The burden of proff lies with the nuclear. thanks.  Hehey.

nuke fuel costs

Just to throw a few logs on the fire of the nuclear cost debate, here are a couple of interesting reports from the World Nuclear Fuel Market Conference.

This from Scott Melbye, vice president of marketing for Cameco Corporation:

According to Melbye, the uranium industry indeed has a future shortage, looming on the horizon -- beyond the imminent shortfall through 2009, and again around 2013. This one could occur in 2025.  This came about, he explained, because uranium miners suffered through years of baggage, the excess brought about opposite effects, and also because the industry is complacent about the future. His recommendation: Patience is required.

And there's this report about a presentation titled "Mythology -- Some Sad Realities":

Speaking of mythology, Dr. Haksoo Kim, Acting Director of Fuel Supply for Exelon Corp, decided to explode a few of the myths circulating around the uranium industry.

On Page 12 of his presentation, he announced "Some Happy Myths." We've all heard them and digested them as truth. These same myths have been posted on the websites of the more promotional 'uranium' companies hoping to lure the unwitting investors to buy their uranium exploration story.

Dr. Kim opened our eyes.

He told his audience that fuel is four to five times the 'hyped' cost of nuclear power - between 20 and 25 percent instead of the mere five percent.

He announced, "At $1000/pound for uranium, a nuclear utility's fuel cost would rise to $70/MWH compared to $5/MWH at legacy contract prices of about $20/pound.

Dr. Kim shot down the premature conclusion that utilities would rather pay the high prices instead of going through a costly decommissioning process. He said, "There is no compulsion to immediately decommission - stations can be held in standby or cold shutdown."

Finally, he took up the matter of `utilities not caring about fuel costs.' He pointed out, "Take $900 million from your company's annual net profits. See how happy your management is."

Because of what we've previously been led to believe, we questioned his numbers and conclusions. So we asked TradeTech's Gene Clark for a second opinion. Clark emailed back and confirmed Dr. Kim's calculations were accurate...

Nuclear costs III

amazngdrx - Not even consumer demand can make the wind blow every day in Texas.  it is too bad that we cannot use all of the hot air coming from Grist anti-Nuk bloggers to generate power in Texas. I note in an earlier comment the problem related to the cost of wind power as a factor of Peek Load generation.  Why don't you figure my comment out, rather than telling me how we are going to solve all our problems with the intermittent Texas wind.

The construction costs of second generation Nuks in the U.S. ran up to $5000 per KW.  The first two General Electric ABWR's commissioned in Japan in 1996 and 1997, costs about $2000.  A number of 4th generation reactors featuring dramatically different designs are quoted in the 1000 per KW range.  These include the CANDU ARC and the Pebble Bed Gas Cooled Reactors.  The Pebble Bed is touted for its outstanding safety.  

The latest estimate of construction time for a power reactor is three years. Many of the problems of first and second generation reactors had to do with designed flaws that had to be corrected during construction.  Other cost over runs were related to design changes that were mandated by changing regulations.  The custom manufacture of reactors, rather than using mass produced designs also contributed to the high costs of early reactors.  You would not expect a Ford to cost as much as a Ferreri, but the Ford might turn out to be far more dependable.  

Sweden reports reactor waist disposal costs of 0.13 cents per KW-Hr.  French authorities estimate that the cost of waste disposal and decommissioning will be 10% of the construction costs.  Some very old reactors, dating back to World War II have been very expensive to ddecommission, but recent reactor design has recognized decommissioning costs to be part of the package.

Your cost estimates are thus based on worst case experiences both in construction and decommissioning costs.  But why shouldn't we assume that the French experience with mass production of a standard reactor design, coupled with built in decommissioning plans, would still leave reactors as the cheapest option for eco friendly electricity.

fuel costs

Laurence Aurbach, I would like to call your attention to two sources of raw materials for reactors.  The first is U235 and Pu239 from retired atomic devices.  There is enough of Bomb grade materials in storage in the United States to run many many reactors.  There are also hundreds of thousands of tons of depleted Uranium in storage.  Depleted Uranium, by the way still contains, enough U235, that it can be reprocessed for More U235, or alternatively require less U235 for enrichment to reactor grand.  There is actually a good deal of Uranium in the fly ash of coal fired power plants.  Why not extract that Uranium to go into reactors, rather than lock it up in cement as is thew present practice.  There are other sources of Uranium and Thorium is an alternative to Uranium that will be used in VI generation reactors.

Nuclear is, of course, bigger ...

than it appears to be on the lying graph linked by 'GreyFlcn'. If that showed the true situation, it would hardly justify the Saturday-night efforts oil money has been making in this thread.

Last year's, IIRC, 2,658 billion kWh worldwide production was ~630 million tonnes of oil equivalent. The graph appears to scale fossil fuels' contribution according to the heat they produced without counting nuclear energy on the same basis; so although oil-fired power stations would have needed 4.2 billion barrels to produce as much electricity, the graph scales the nuclear contribution as if it had been, so to speak, only 1.4 billion barrels of electricity. As if this electricity were worth no more than the heat it might have produced in resistors. Also, the graph shows a nuclear electricity production decline in the next 20-30 years, which the environmentally concerned public is unlikely to allow, and uranium availability is unlikely to force, what with the rapid increase in proved uranium reserves between 2003 and 2005.

"Nevada Solar One", a concentrating solar thermal power station with a peak power of 64 MW started up in Nevada two days ago. Its expected year-round average production of 14.1 MW makes it, however, equivalent to an 18-MW conventional thermal station, and its capital cost more than US$14 billion per GW, with the understanding that significantly less than a GW would be yielded in the winter. I'm told this makes the per-kWh price more than US$0.20. This is a lot less than PV-solar prices, but high enough to explain why less than 30 GW of CSP plant are under construction.

"Nevada Solar One"

"Nevada Solar One" is 1970s era technology (troughs).  Solar industry leaders (like nuclear leaders) have abandoned old ideas for new systems that are more cost efficient and scalable.  In solar that means cogeneration power towers with heliostats.

Correction, 15.3 MW year-round average ...

not 14.1 MW. So only US$13 per watt. It's rapidly improving!

Big dishes ought to be keen

I agree that concentrating in only one axis is a relatively cheap and common spectacle, unable in principle to concentrate sunlight more than 215-fold, while two-axis concentration can do 215^2-fold. A heliostat is a dish that has settled piecewise onto the ground, like the Jodrell Bank radio dish only different, so should be able to produce very high temperatures.

Big dish people are moving into heliostats.

Because the sun is not a point source of light concentrations are: troughs 70:1, heliostats towers 500:1, and dishes greater than 1000:1.  

Heliostats and troughs have cosine losses (the angle of sun relative to mirror surface).  Dishes have thermal losses from pipes in the field.  The relative performance costs of heliostats and dishes are not clear.  

Heliostat systems are big (finance likes big) and heliostats can be scaled very quickly on rough terrains.  Dishes are good for small niche thermal markets.  Heliostats have advantages for big industrial process heat, district heating, and cogeneration systems.

Solar power plant explodes

DAGGETT, Calif., Feb. 26 (UPI) San Bernardino County authorities say a tank of chemicals at a solar power plant in Daggett, Calif., has exploded, spawning a fire that may burn throughout the night. Fire Department spokesman David McLees says all the employees at the SEGS2 plant were accounted for shortly after the explosion rocked the plant at about 6:05 p.m. today. McLees says the fire is being fueled by a 700,000-gallon tank of Therminol, a fluid used in heat transfer because it can be heated to 850 degrees. The fluid is heated on solar panels, where it reaches maximum temperature, then runs through pipes in a heat transfer area, where it turns water into steam. The steam powers turbines that create electricity. Sheriff's deputies say a 1/2-mile area along Interstate 40 near Barstow is being evacuated because of Therminol's slightly toxicity. McLees says firefighters have no estimated time of containment for the fire.

Where's that nuclear waste?

Last time I checked it's still sitting in cooling ponds scattered around the country for maximum radioactive dispersal and terrorist availability.

Hanford in Washington is still a leaky disaster. Please show me the site where concentrated solar power has permanently destroyed local groundwater.

My little county installs more solar capacity every year. There are panels on houses, gasoline stations, parking lots, college buildings, the brewery and the county jail. Total added nuclear capacity in California- zero. Total political objection to solar installations-zero. Congressman-R, Wally Herger.

Nuclear power
plant shutdowns where used as part of the Enron plan to defraud California and extort increases in power prices. THAT'S the source of cheerleading for nuclear power; the capacity to hold population's hostage to political/economic demands.

Combine concentrated solar power and low-grade geothermal and you have a power source that will give you more power 24/7 than either source alone.
What's bizzare is that those solar plants in Nevada where built in an area of high geothermal power availability.

The nuclear power industry is a fraud.

Pangolin wrote: Total added nuclear capacity in California- zero.

Other than through uprates, is it legal to add nuclear capacity in California?


world-nuclear.org/info/inf17.html

Increased nuclear capacity in some countries is resulting from the uprating of existing plants. This is a highly cost-effective way of bringing on new capacity.

Numerous power reactors in USA, Belgium, Sweden and Germany, for example, have had their generating capacity increased. In Switzerland, the capacity of its five reactors has been increased by 12.3%. In the USA, the Nuclear Regulatory Commission has approved 110 uprates totalling 4700 MWe since 1977, a few of them "extended uprates" of up to 20%.

Nuclear waste

There will be asolution to the Nuclear waste problem when ever the political will emerges to solve it.  It is certainly possible to identify and use stable geological formations where nuclear wast can be safely stored for as long as we would ever want.  Incontrovertable empirical evidence shows reactor waste can be safely stored for up to one and a half billion years.  The anti=nuk crowd simply resists any practical solution to the nuclear waste problem out of their perverse and irrational hostility to nuclear power.

Charles Barton
Well

Well, if you could teleport the nuclear waste into place.  That'd solve a lot of problems.

The issue is when it's in transit.

Because of this, Nevada isn't to happy about having the nation's nuclear waste trucked to a facility an hour away from Las Vegas.
(i.e. Their cash cow)

This is probably why Nevada likes Geothermal and CSP so much.

Since both of them can compete with Nuclear on cost and performance.

What problems are associated with nuke-waste?

GreyFlcn wrote: if you could teleport the nuclear waste into place.  That'd solve a lot of problems.

Which problems are those that it would solve, and how do you figure it would it solve them?


"Peaceful Atom"=fraud.

In the late 1950's thorium fueled reactors were tested and proven to be viable. Unlike uranium reactors thorium reactors cannot produce bomb-grade plutonium or uranium. Thorium is more common in the earth's crust than uranium. There are no commercial thorium fueled reactors in operation in the US.

In the mid-1960's molten-salt reactors were designed, tested and proven to be operable. Molten-salt reactors are capable of consuming "nuclear waste" such as plutonium and actinides and do not produce additional waste in the form of spent fuel rods. Adding thorium to the fuel mix of a molten-salt reactor poisons the plutonium and makes it unsuitable for bomb making. Molten-salt reactors are also not susceptible to core meltdowns such as the one at TMI.  None are in operation in the US.

It is no coincidence that "nuclear waste" contains bomb grade plutonium. The reactors were designed that way. Larger volumes of more dangerous wastes provide permanent profits for corporations involved in the handling and protection of those wastes.

Production of fuel rods and handling of wastes are major profit centers for the nuclear power industry. Nuclear "waste" processing also produces the plutonium needed for nuclear weapons and the "depleted" uranium needed for armor-piercing projectiles.

Several reactor types that could have produced power without producing bomb-grade plutonium have been available. None of those reactor types are in use. Reactor types that could have consumed nuclear waste and reduced waste volume have been neglected in favor of reactors that produce more waste than was absolutely needed.

In California refueling of nuclear reactors was used as a pretext to extort money from the state and it's population by Enron. This would not have been possible with distributed solar/wind/geothermal power sources. Nuclear power is a tool for political control as much as power production.

There's the fraud. Nuclear power is about profits and politics not power.

Put the Carbon Back

The issue with nuke waste is not transit

Thorium reactors can produce bomb-grade uranium-233, or they can be tweaked not to. My impression of this complex matter is that this is the reverse of the case with today's uranium-burning ones, which produce plutonium that is not weapons-grade unless one goes out of one's power-producing way to make it so.

The issue with nuclear waste, or nuclear anything, is not transit. The issue is oil and gas revenue, especially tax revenue, that never was. That is why there are so many, many "issues".

Generation VI reactors = Molten Salt

Molten Salt technology is not quite ready for primer time - That is mass production of a parge power generating model - but it can be in about 15 years.  The concept was been proven at ORNL, which built and operated three generations of Molten Salt reactors in the 1950's and 1960's.  I have documented, in my blog, Alvin Weinberg's 1967 statement on Molten Salt Breader Power generating reactors: "WHY DEVELOP MOLTEN-SALT BREEDERS?"  

http://www.xanga.com/bartoncii/591431627/alvin-weinberg-o ...

I have also discussed Weinberg's integrity and vision:

http://www.xanga.com/bartoncii/591790491/alvin-weinbergs- ...

Weinberg was a real pioneer in concerns about anthropogenic global warming.  He discussed it in a paper he published in Science in 1974, and testified to Congress about the danger of CO2 emissions in 1975.  He was fired as director of ORNL because his concerns about reactor safety clashed with the "gung-ho" approach of the Nuclear establishment.  Three Mile Island vindicated Weinberg's safety concerns, but only in the 21th century is his last baby, the molten Salt Reactor being appreciated.

Charles Barton

Good point Pangolin

Maybe part of a nuclear compromise ought to be that we who are anti-nuke insist on a switch to non-proliferation risky thorium?  Sounds like a possibility.

http://amazngdrx.blogharbor.com/blog John Schneider, Northern Wisconsin
Economics of power

The cost of coal power is not the cost of coal, rather it is the cost of burning coal.  The cost of burning nuclear fuel is not cheaper than the cost of burning coal.

Plutonum and non-proliferation

Anti-Nuks have a number of bugaboos.  Non-proliferation is one.  North Korea proved that any moderately sized failed state can build nuclear devices.  The formula is simply starve your people.  Sell the food they would have eaten, and use the money to buy nuclear technology.    Most power generating reactors are going to go to states that either are members of the nuclear club, or could be if they chose to be.  So what is the big concern about non-proliferation?  

The point is not, I think, to create a perfect world, but to not do things that will make the lives of our grandchildren worse than ours has been.  By our grandchildren I mean any kid who will be born on earth, in the next couple of generations.  We are creating great problems for them by burning fossil fuels at rates which cannot be sustained both because the resources of our planet are limited, and because of the side effects of our burning fossil fuels for energy,  

Alvin Weinberg pointed out 50 years ago, Molten Salt reactors can bread Thorium into U233.  There is approximately 4 times as much Thorium on the earth, as there is Uranium, so a Thorium economy is going to last a long time.  But you can use PU239 as a fuel in Molten Salt reactors.  In fact another non-proliferation advantage of Molten Salt Technology, is that you can use up the world's current stock of weapons Pu239 as fuel in Molten Salt Reactors.  Decreasing the world's current stock of unused Pu239 would be highly desirable from a non-proliferation viewpoint.

I am however encouraged that amazngdrx's anti-Nuk resolve appears to be wavering.  Perhaps this debate is doing some good.

Churning Crust

I read a report yesterday that they had discovered the earths crust constantly "churns" or subducts in places -- pushes or sucks down parts of itself which then gets recycled after going down under the plates.

It seems to me we could bury nuclear waste in these areas of subduction (Chile) and then it would basically be gone after a while (no where near groundwater).

So That's How The G8 Will Do It

Richter pointed to France as an example. It produces only half the amount of CO2 emissions per unit of GDP relative to the rest of the world thanks to nuclear.

Ok, I wonder where they (G8) came up with the cut 50% figure.

They already know that France, with it's 80 percent nuke energy generating capacity, has already achieved a 50% cut.

So if we (at the very least) go with nukes until we get fusion going we can meet a 50% cut by 2050, hands down.

Oh, btw, here's a cool variation on fusion who's inventor (Robert Broussard) was invited over to Google to give a tech talk:

France: Vive Les Nukes

When much of the world spurned nuclear power, 30 years ago, the French, being French, decided to go their own way and embrace it. Paris, the "City of Light," is lit by nuclear energy, which powers just about everything else in France: its homes, its factories, even its high speed railroads.

Nearly 80 percent of the country's electricity comes from 58 nuclear power plants, crammed into a country the size of Texas. Pierre Gadonniex, the head "Electricite de France," the country’s national utility says it all began with a French obsession for energy independence.

"In France, we have nearly no coal. We have no oil. So clearly, nuclear appeared to be the best way," Gadonniex explains. "And 30 years later, it appears to be a very smart decision."
