World Wind exceeds US Nuclear

The United States is by far the global leader in nuclear power plants with technically 100 operating reactors (though if you remove Crystal River, two San Onofre units and Kewaunee from this list you only have 99 reactors).  France is a distant second with 58 operating reactors.  So it was with some pleasure that i read that the global fleet of wind turbines had reached the 300 GW level, which is equivalent to 114 nuclear reactors*.

Future so bright, i've got to wear shades

Also heartening is that in the first 5 months of this year the US built 29% of it’s new capacity in renewables.  This is even with historically very low natural gas prices.  Renewables installed capacity is more than twice the new coal capacity.

* Remember installed capacity is the maximum amount of power a generator can produce, to get the actual amount of power produced you need to multiply by the capacity factor.  For wind turbines this is about 35%, because they do not run all the time.  Nuclear reactors run about 90% the time.  A typical reactor is around 1 GW capacity.

Solar aint dead

i comment on lots of articles about renewables and efficiency and clean energy solutions and against reactors.  With some regularity i end up in debates with people who are pro-fossil fuel or pro-nuclear folks, who have recently been happily chirping that the biggest solar factor in China has gone bankrupt and solar is dead.

While i have more than my share of problems with industrial capitalism, after the industry shake up, it is choosing a rebound in total global installed solar photo voltaic panels from 31 GW in 2012 to an estimated 53 GW in 2015

In other renewable news, nuclear power continues its decline in the fraction of the total primary energy it produces in the US with 8.0 quadrillion BTUs in 2012, while renewable energy continued to increase its share and outstrip nuclear at 8.8 quadrillion BTUs.

CitiBank and General Electric are already claiming on shore wind power (where not endlessly delayed by bureaucracy) is already the cheapest form of energy on earth.

I can hear solar whispering the words of Mark Twain after hearing of his obituary in the New York Journal.

“The reports of my death are greatly exaggerated”

The last two nails in nuclear powers coffin

Two recent news items should be enough for serious investors to short sell nuclear power stocks.

The first piece is a cheery story from Germany.  Germany produced 22 gigawatts of solar power that were fed into the national grid on Saturday that met 50% of the nation’s midday electricity needs.  This is more electricity than 20 nuclear reactors at full production.  Germany only has 17 reactors total, 8 of which were closed after Fukushima, the rest of which will be shuttered by 2022.

Perhaps LA and Houston could follow Berlins lead?

Please remember that according to Whole Earth Catalog editor and heretic green guru  Steward Brand there are 4 reasons why renewables sources can not replace nuclear power:

  • Baseload: Wind and photovoltaics can’t keep the lights on because they can’t run 24/7.
  • Footprint: Photovoltaics need 150 times, and wind farms over 600 times, more land than nuclear power to produce the same electricity.
  • Portfolio: We need every tool for combating climate change, including nuclear power.
  • Government role: The climate imperative trumps economics, so governments everywhere must and will do what France did — ensure that nuclear power gets built, regardless of economics or dissent.

Germany is proving  these all wrong.  Clever Germans have optimized their power grid so it can handle up to 50% feed in from a completely intermittent source.  I’ve read several articles by critics of the German renewables strategy, none even mention footprint, this is a non-issue.  At these levels Germany can look seriously at wind and solar as dominant players in their energy portfolio.  And clearly the governments role by legislating the highest electricity prices in the world, including Feed In Tarrifs (FIT) to level the playing field for solar, is having the desired climate change effect.  Even with nuclear rapidly declining.

Also remember that despite the dismal colors on the above map:

It is worth talking about FIT a bit, because it is the strongest argument against solar.  German power users pay about $6 billion a year in solar subsidies.  The Japanese are looking at easily $250 billion for the cost of Fukushima.  That is all we really need to say  about Feed In Tarrifs.

The other piece of news is far less cheery, but possibly more important, despite being hidden away on the technology pages of most newspapers.

The Japan’s #3 cell phone maker, Softbank, has announced a mobile phone which detects and maps radiation.

This will map the demise of nuclear power

What the articles about these phones does not say, but is the clearly blaring future technological reality, is that this type of phone will spawn a social network.  In this new network there will be a tremendous independent shared data set about nuclear hot spots.  These phones, with casual and dedicated users will map millions of hot spots and long term uninhabitable locations.

Imagine yourself as an affluent retired Fukushima refugee.  Someone who can never go home, but still has money and anger.  What might you do?  You might start scowering the country side for hot spots.  You might even think “i will sacrifice my own long term health so my grandchildren know where this invisible poison is”  The more lethal locations show up, and there are already some mapped, the less likely it will be that the 50 closed reactors in Japan will ever re-open.

Imagine yourself the mom of a young child, you will network with your other mothers to find safe spaces for your kids to play and go to school.  And one day a bad storm blows in a bunch of radioactive debris and you have to leave your town which has been safe before.  Because it turns out fallout is just that fickle, only we did not watch it before.

Simply put, these devices combined with social networking will begin to map the real effect of Fukushima and when the world sees it, it will be very hard to build more reactors.

Japan just instituted their own renewable feed in tarrifs, they are twice as lucrative as Germany’s
