Renewables vs. Nuclear: Do We Need More Nuclear Power?

Renewables vs. Nuclear: Do We Need More Nuclear Power?


...Let’s take a look at the last 10 years and the next 10 years…

New U.S. renewable and nuclear capacity added the last 10 years (output):

55 GW utility wind (22 GW)
17 GW rooftop PV solar (3.5 GW)
10 GW utility PV and solar thermal (2.5 GW)
15 GW biomass and biogas (12 GW)
3 GW Geothermal (2.5)
Total renewables: 100 GW (42.5 GW)
Total nuclear: Marginal increase from existing plants
(2004-2014 = approx 2.6MWe of up-rated nuclear generation - K)

.....

U.S. renewable and nuclear plan the next 10 years capacity and (output):

130 GW utility wind (52 GW)
75 GW rooftop PV solar (15 GW)
35 GW utility PV and thermal solar (9 GW)
60 GW biomass and biogas (51 GW)
5 GW Geothermal (4 GW)
Additional renewable power next 10 years: 305 GW (131 GW)
Additional nuclear power next 10 years: 5.6 GW (5.1 GW)

The above output numbers for renewables assume no advances in wind or solar efficiency and no grid storage. Both assumptions will become completely false, so the 131 GW number should be considered a minimum number....


There is much more to the discussion: http://www.renewableenergyworld.com/rea/blog/post/2015/04/renewables-vs-nuclear-do-we-need-more-nuclear-power?page=all

Now, about that minimum number and storage:
Tesla-Powered Wal-Mart Stores Attest to Musk's Energy Storage Ambitions

...

...

While companies like Coda Energy, Green Charge Networks and Stem have also applied for SGIP funds, Tesla accounts for almost half of all storage applications, Bloomberg New Energy Finance said in an April 2 report published for clients. BNEF also said Tesla accounts for about 70 percent of SGIP storage projects connected to California’s grid.

Jackson Family Wines, based in Santa Rosa, has a new partnership with Tesla involving battery storage and several vehicle charging stations, according to the February issue of Wine Business Monthly. The winery declined to comment.

Mack Wycoff, Wal-Mart’s senior manager for renewable energy and emissions, said the company is intrigued by energy storage. “Instead of pulling electricity from the grid, you discharge it from the battery,” he said. “Ideally you know when your period of peak demand is, and you discharge it then.”

Mike Martin, Cargill’s director of communications, declined to provide details about how the company plans to use Tesla batteries at the Fresno plant. The 200,000-square-foot facility, one of the largest of its type in California, produces nearly 400 million pounds of beef each year.

Janet Dixon is director of facilities at the Temecula Valley Unified School District in southern California, which plans to install solar panels at 20 of its 28 schools this summer. Dixon said that SolarCity is the solar provider, and five of the facilities will have Tesla batteries.

Floating nuclear power plants promise major savings for Arctic mines

Floating nuclear power plants promise major savings for Arctic mines
Diesel-fuelled power “not sustainable for the scale of development we want to see"


PETER VARGA



Mining projects in Nunavut are saddled with high expenses that could discourage development.

With that in mind, why not go for a tried and proven cheaper source of energy that can come and go on the high seas, and reach the territory’s coastal communities?

That’s just what Dunedin Energy Systems Ltd., an Ontario-based energy consulting firm, suggested when it pointed to “floating nuclear power plants” as an alternative energy source, April 16 at the Nunavut Mining Symposium in Iqaluit.

Nuclear power generators have been cruising the high seas in the ships of the world’s biggest navies since the 1950s, Peter Lang, president of Dunedin, told an audience at the symposium.

“Since then, civilian applications have come along,” Lang said ...

Firebombing of Tokyo: Introducing The Great Tokyo Air Raid

Saotome Katsumoto and the Firebombing of Tokyo: Introducing The Great Tokyo Air Raid

Translator’s Introduction
Richard Sams

March 10 is the 70th anniversary of the Great Tokyo Air Raid. Although Tokyo was bombed more than 100 times from November 1944 to the end of the war, the firebombing centered on the Shitamachi district in the early hours of March 10, 1945, was by far the most devastating air raid on the capital. In less than three hours from just after midnight, 279 B-29 bombers dropped a total of 1,665 tons of incendiaries.1 By dawn, more than 100,000 people were dead, one million were homeless, and 16 square miles of Tokyo had been burned to the ground.

More people were killed in the indiscriminate firebombing of March 10 than in the immediate aftermath of the dropping of the atomic bomb on Hiroshima. After the war, while Hiroshima and Nagasaki became symbols of Japan’s suffering and the peace movement, the Great Tokyo Air Raid was virtually excluded from public discourse. Hardly anyone wrote about the air raids that reduced the capital and most of Japan’s other cities to ashes, and the few articles that did appear in newspapers attracted little interest. For a quarter of a century after the war, while memorial services were held every year on August 6 and 9 for the victims of the atomic bombings and covered widely in newspapers and on television, the devastating firebombing campaign over Tokyo and much of urban Japan was quietly forgotten. While school textbooks, novels, poetry and films memorialized the atomic bombing and its victims, silence reigned with respect to the firebombing raids...

The 9 unbreakable rules of the Wile E. Coyote/Road Runner universe

The 9 unbreakable rules of the Wile E. Coyote/Road Runner universe


Rule #1: the Road Runner cannot harm the coyote. Warner Bros
The Road Runner and Wile E. Coyote, those cartoon favorites from Warner Brothers' beloved Looney Tunes, spent four dozen animated shorts engaging in ridiculous mayhem through the American Southwest.

Though the behavior of the two seemed spontaneous and silly, their comedic timing was a carefully constructed reality made by Chuck Jones, perhaps the most famous director at Warner Brothers' animation division.

Yesterday, Jones' rules for that reality went viral when film director Amos Posner tweeted a picture he had taken at the "What's Up, Doc? The Animation Art of Chuck Jones" exhibition at the Museum of the Moving Image in New York City:

:large

These rules come from Jones' 1999 autobiography, in which he wrote:

Just as I decided later that there would be no dialogue in the Coyote-Road Runner series because it seemed like a good rule, or indeed it would be a good rule if it was consistent; all comedians obey rules consistent with their own view of comedy. In my opinion, Jackie Gleason got more milage out of threatening to hit somebody than the Three Stooges ever did by doing so...

Carbon crash, solar dawn: ... why solar has already won

Carbon crash, solar dawn: Deutsche Bank on why solar has already won
By Giles Parkinson on 3 March 2015

...

...In a detailed, 175-page report, the Deutsche analysts led by Vishal Shah say the market potential for solar is massive. Even now, with 130GW of solar installed, it accounts for just 1 per cent of the 6,000GW, or $2 trillion electricity market (that is an annual figure).

But by 2030, the solar market will increase 10-fold, as more than 100 million customers are added, and solar’s share of the electricity market jumps to 10 per cent. By 2050, it suggests, solar’s share will be 30 per cent of the market, and developing markets will see the greatest growth.

“Over the next 5-10 years, we expect new business models to generate a significant amount of economic and shareholder value,” the analysts write in the report. Within three years, the economics of solar will take over from policy drivers (subsidies),

Their predictions are underpinned by several observations. The first is that solar is at grid parity in more than half of all countries, and within two years will be at parity in around 80 per cent of countries. And at a cost of just 8c/kWh to 13c/kWh, it is up to 40 per cent below the retail price of electricity in many markets. In some countries, such as Australia, it is less than half the retail price.

The case for solar will be boosted by the emergence of cost-competitive storage, which Deutsche describes as the “next killer app” because it will overcome difficulties in either accessing the grid or net metering policies. ...

The video sensation that could tip balance against coal in China

The video sensation that could tip balance against coal in China
By Giles Parkinson on 4 March 2015

For the past few days, the online community in China has been abuzz over a 104-minute documentary, Under the Dome, that has galvanised the population and even major investment banks who believe it may just tip the balance against fossil fuels in the world’s biggest polluter.

Under the Dome, a documentary on air pollution produced by Chai Jing, a former CCTV investigative journalist who had already reached celebrity status in China, has been viewed more than 200 million times in its first four days of release.

It has been widely applauded in the online community, and, most pointedly, drew praise from Chen Jining, the newly appointed Environmental Protection Minister, who thanked the film maker for bringing public attention to China’s chronic pollution issues.

Already, its potential impact is being compared – by investment banking giant Merrill Lynch – to Al Gore’s An Inconvenient Truth, and Rachel Carson’s A Silent Spring for its potential impact on the coal industry. Because of its endorsement by the Chinese government, Under the Dome could be even more powerful.

Indeed, Merrill Lynch said in a note to clients that the film’s impact could spell bad news for coal miners, coal generators, and oil refiners, and it could also cause ripple effects through the Chinese debt markets, even to the point where the Chinese currency might have to be devalued.

The anti-pollution ...

The Policeman Fell

It's possible the Tamir Rice shooting was an accident.

At 7:12 to 7:15
The shooting officer disappears the instant after Tamir goes down. He can be seen picking himself up from the ground as he emerges from behind the car at the trunk.

One possibility is that he exited the vehicle with weapon in hand, pointed it at Rice, slipped and in trying to keep his balance, pulled the trigger. The way he leans on the car for support makes me think he is in a state of shock.

I'm not trying to excuse the shooting, because even if it was an accident it almost certainly could have been prevented if the overall tone of police response were not so aggressive.



BTW, there is a news feed from http://www.killedbypolice.net/ that reports on every officer involved death on a daily basis. They are building a database from news reports.
Please subscribe and spread the word about it so that understanding of the scope of this problem becomes common knowledge Too many think it is far less frequent than it is.

MIT's Jon Gruber just got fired from the Massachusetts health care board

MIT's Jon Gruber just got fired from the Massachusetts health care board
Updated by Sarah Kliff on February 25, 2015, 5:46 p.m. ET @sarahkliff sarah@vox.com

MIT economist Jonathan Gruber has been fired from his post helping to oversee Massachusetts' health insurance marketplace, the Boston CBS affiliate reported Wednesday.
Gruber previously became embroiled in a controversy over video-taped remarks that showed him saying the health law only passed because of "the stupidity of the American voters."
More recently, Vermont's state auditor has accused Gruber of overbilling the state for consulting work he did on it's (now-failed) single-payer health care plan....
