Balancing wind with multiple renewable resources—including solar, which does not normally peak when wind does, and baseload power from geothermal and biomass—could mitigate the temporal variability in generation. Reaching the goal of 20 percent nonhydropower renewables by 2035 could be achieved by adding 9.5 GW per year of wind power and a total of 70 GW of solar PV and 13 GW each of geothermal and biomass. Using multiple renewable resources to reach this level would take advantage of the geographical variability in the resource base.

"Reaching the goal of 20 percent nonhydropower renewables by 2035 could be achieved by adding 9.5 GW per year of wind power and a total of 70 GW of solar PV and 13 GW each of geothermal and biomass."
We now have more than 10GW of solar capacity in the US, so most of this boom will be added to that within another 2 years. That puts us around 70% of the way to the 2035 solar level mentioned by NAS 20 years earlier than they hypothesized.
We have 60GW of wind capacity installed, but the performance of the wind industry is still a problem in that it is responsive to the existence of the Production Tax Credit, which the Republican House is sure to allow to expire at the end of this year. Every indication is that wind could deliver the 9.5GW of capacity easily if the Republicans in the House would stop screwing with the them and passed a stable policy that developers could count on when planning.
(How many times have you heard them attack the ACA by saying stable government policies are required for business growth? They aren't screwing with the PTC by accident.)

Electric Vehicles: Mobile Agents of the Grid Edge
Electric vehicles will serve a much larger purpose than just transportation.
November 29, 2013
Electric vehicles are the mobile agent of the grid edge. The interest in decoupling transportation from fossil fuel consumption is primarily driven by environmental and economic motives, but grid-edge considerations focus on the system benefits of a large EV fleet. Instead of creating additional peaks by simultaneous charging of large numbers of vehicles, electric cars could make use of excess wind power at night, serve as mobile storage devices, and create new revenue streams for car owners. The EV market segment includes plug-in hybrid and electric-only EVs, vehicle-to-grid technologies, and smart charging solutions.
Deployment and Growth Projections
Plug-in electric vehicles sold twice as well in the first half of 2013 than they did in 2012, according to the DOE. This rate of growth in the market appears to be much faster than in the early phase of hybrid vehicles. Many industry observers point to this as a harbinger of massive success to come. However, even if the share of EVs relative to total car sales is increasing rapidly, it is still small, as the following chart illustrates. The market is bound to reach a turning point in the coming decade. Polk Research found that the U.S. car fleet hit a new record age of 11.4 years in 2013, up 16 percent from 2002. During the same period of time, fuel efficiencies have risen from a miles-per-gallon perspective, so the gap between old models and newer models with better fuel economy could spur increased demand in the short term. The Rocky Mountain Institute predicts that 50 percent of all U.S. vehicles will be electrified by 2050.
Trends, Thought Leaders, Vendors, Ideas
The EV market mirrors many challenges of the grid edge at a smaller scale. Factors to consider include:
Standardization: Standardization is a major stepping stone on the pathway to a plug-and-play environment of charging stations. The importance of standards is not limited to charging stations: if electric vehicles are to be part of a dynamic grid infrastructure, standardized communication protocols are just as important as OpenADR for demand response, in terms of creating a single language with which EVs and energy service providers can communicate.
U.S. efforts around V2G remain rare, but they do exist....

Can 3-D Printing Turn Space-Based Solar Into a Reality?
NASA is investing, but cost is still the question.
Herman K. Trabish
November 27, 2013
“The overall vision is to create a ‘satellite chrysalis’ with compact, durable ‘software DNA’ assembly instructions, and the ability to fabricate space system components on-orbit instead of building them on the ground,” explained Rob Hoyt, CEO and Chief Scientist of startup Tethers Unlimited, Inc.
TUI has won two rounds of funding for its SpiderFab 3-D robotic printer from the NASA Innovative Advanced Concepts (NIAC) program. A $100,000 award allowed proving of the technical feasibility and value proposition of the technologies and won TUI a $500,000 award to continue development.
“Our analysis shows we can get orders of magnitude improvement in the stowed volume and mass of space systems,” Hoyt said. The transport of compact materials instead of bulky finished products, “could reduce stowed volume tenfold and mass by 50 percent to 80 percent.”
3-D printing and robotic construction of components on-orbit would allow a smaller, less expensive launch rocket that will “improve performance per cost by orders of magnitude,” Hoyt said.
Once in space, TUI’s Trusselator, the first step in the SpiderFab architecture, would ...

400 km Range Nissan LEAF Could Become Reality
One of the unique features of the Tesla Model S is the option to order different size battery packs. You can order it with with a 60kWh or 85 kWh battery pack, the later offering range close to 500 km (NEDC) per charge.
The larger the battery pack, of course, the more expensive the car, but as Tesla is finding out, a lot of its customers are opting for the larger size and greater range, a trend that hasn't gone unnoticed at Nissan, makers of the LEAF all-electric car.
During an interview with Plug-In Cars at the recent LA Auto Show, Pierre Loing, vice president of product and advanced planning and strategy at Nissan, hinted that his company may offer a similar multi-pack size option.
At present the LEAF is rated at 200 km (NEDC) per charge, doubling the size of the pack to nearly 50kWh would push this to 400 km, although the price of the car would increase as well; either the sales price or monthly battery rental cost, if that option were offered.

Coal industry accuses UN climate chief of 'ignoring reality'
Coal lobbyist Milton Catelin says Christiana Figueres is too focused on climate change and misunderstands energy sector, reports RTCC
Sophie Yeo for RTCC, part of the Guardian Environment Network
theguardian.com, Monday 2 December 2013 10.07 EST
The head of the World Coal Association (WCA) has accused UN climate chief Christiana Figueres of ‘ignoring reality’, following her call to the coal industry to invest in more efficient technologies.
In an interview, World Coal chief executive Milton Catelin told RTCC that Figueres’ lack of expertise in the mining and energy sectors meant she “misses some of the fundamentals about the energy sector”.
He was responding to a speech Figueres made to a ‘Climate and Coal Summit’ on the sidelines of UN negotiations in Warsaw two weeks ago, where she told the audience that “coal must change rapidly and dramatically for everyone’s sake.”
Figueres called for the closure of all low-efficiency subcritical plants, a roll out of carbon capture and storage (CCS) technology and a collective decision to leave most coal reserves in the ground.
The UN climate chief was heavily criticised by green groups ...

Science Textbooks Across the Country Will Teach Real Science Because of A Decision In Texas
BY RYAN KORONOWSKI ON NOVEMBER 29, 2013 AT 7:02 PM
Because of a small meeting in Texas on Friday, science textbooks across the nation will teach high school students real climate science — and not the version of science advocated by the fossil fuel industry and conservative ideologues.
Last week, the Texas Board of Education voted to approve 14 textbooks used in biology and science classes. “These textbooks were recommended by the top scientists and teachers in Texas,” said Joshua Rosenau of the National Center for Science Education.
Texas is the second-largest textbook market in the country, and because the State Board of Education decides which books to purchase (instead of local school districts), publishers pay serious attention to which books the Board buys. These choices become the basis upon which standard textbooks are written across the country. A publishing executive told Washington Monthly in 2010 that “publishers will do whatever it takes to get on the Texas list.”
The fate of climate science was never certain. In September, some reviewers “insisted that there is no evidence for a human influence on the carbon cycle,” and asked that textbooks include disclaimers saying this.
After giving preliminary approval ...

Survey shows most S. Koreans fear safety of atomic power plants
SEOUL, Nov. 28 (Yonhap) -- An overwhelming majority of South Koreans oppose additional construction of atomic power stations due to safety concerns, a survey showed Thursday.
In the survey commissioned by the Korean Federation for Environmental Movement, a Seoul-based environmental group, 77.8 percent of the 1,000 adults aged 19 or older polled expressed concerns on the safety of nuclear power plants. Only 17.5 percent answered they didn't have fear for the nuclear plants, the survey showed.
The survey was conducted before the government is set to finalize its long-term plan for energy polices.
Last month, a consultation group comprised of private and government experts recommended the government maintain the ratio of power generated by nuclear energy in the range of 22-29 percent in the next two decades, according to sources. This is far lower than the 41 percent proposed for the 2008-30 period under the previous Lee Myung-bak administration.
The plan, if realized, would mean a significant turnaround from the country's decades-old energy policies...
Nuclear power safety
Old boy network forms a chain of corruption
As President Park Geun-hye said recently, it is an unpardonable crime to compromise safety in nuclear power generation in pursuit of personal gain. What kind of catastrophe a nuclear accident can inflict on a nation has been shown by the Chernobyl and Fukushima disasters.
Prime Minister Chung Hong-won shared the president's deep concern about nuclear safety when he promised on Friday to leave no stone unturned in the government's investigation into the provision of substandard parts and materials for nuclear power plants.
Now targeted for criminal investigations are those that are found to have been involved in falsifying test certificates for parts and materials used in nuclear power plants. They have put the nation under the threat of nuclear hazards by trading nuclear safety for their personal interest. None of them will deserve even an iota of leniency....
Arrest warrants sought for 13 in corruption involving nuke power operator
SEOUL, Aug. 7 (Yonhap) -- State prosecutors said Wednesday they have requested court-issued warrants for 13 people to detain them for further questioning on charges that they forged quality warranties of components used in local nuclear reactors.
The suspects allegedly supplied various critical plant equipment to Korea Hydro and Nuclear Power (KHNP), the state-run operator of nuclear power plants, after doctoring their safety tests and certificates, the Supreme Prosecutors' Office (SPO) said.
Releasing a preliminary probe outcome into a snowballing corruption scandal involving the nuclear power operator, the SPO said that two have been put in jail with court-issued warrants pending trial and a decision on warrants for 11 others will be made soon.
Additionally, some of the suspects allegedly took bribes from testing company officials in return for accepting substandard parts with fabricated safety tests, prosecutors said.
"We plan to wrap up the corruption investigation by end of this month...

"The lesson of Fukushima, Mr. Abe, is not the need for better public relations."
Imagining post-nuclear Japan
BY JEFF KINGSTON
SPECIAL TO THE JAPAN TIMES
NOV 30, 2013
Former Prime Minister Junichiro Koizumi has sent shock waves through the political establishment by calling for the end of nuclear power generation in Japan. “There is nothing more costly than nuclear power,” Koizumi was quoted as saying during an interview with Tokyo Shimbun — something Japanese taxpayers are coming to understand very well.
Koizumi may be a late convert to the anti-nuclear movement, but he remains popular, persuasive and, on this issue, absolutely right. Prime Minister Shinzo Abe might get some reactors back online in 2014, but he risks a powerful popular backlash because people are not ignoring the lessons of Fukushima. Koizumi is correct in saying that most politicians would go along with Abe if he stood up to the nuclear village and declared “Abenomics” meant tapping the green growth potential of smart, renewable energy. This is a sustainable and affordable low-carbon model that is far more suitable for Japan and developing nations than pricy nuclear reactors.
The old motto of the nuclear village — “safe, cheap and reliable” — now seems like a bad joke. It is hard to put a price tag on the overall consequences of the meltdowns at Fukushima and the ballooning costs of bailing out Tokyo Electric Power Co., but by some estimates it’s $100 billion and rising. There are still more than 100,000 nuclear refugees driven from their homes by the catastrophe. In early November, the government finally acknowledged that many can never return to their ancestral homes. Local farmers and fishermen have a deep hole to climb out of to regain consumer trust, while tourism has been hammered and faces tough prospects. Lingering stigma and health concerns are also exacting a stiff psychological toll on residents.
In the global lexicon, Fukushima is shorthand for nuclear disaster in much the same way as Chernobyl before it. It is indelibly tarnishing the Japan brand and will linger ominously despite Abe’s reassurances that the situation is under control. It doesn’t help that polls show that only 11 percent of Japanese believe Abe, and even Tokyo Gov. Naoki Inose has suggested that Abe mislead the International Olympic Committee. The lesson of Fukushima, Mr. Abe, is not the need for better public relations.
Problematically, Abenomics relies heavily on nuclear energy...

BMW to Electrify entire model range
BMW product chief Herbert Diess says “Electricification will be a central thread in what we do, be it plug-in hybrid, hybrid or full electrification".
Diess told Autocar "all BMW models will soon need to be sold with some form of electrification - be it in hybrid form or pure electric drive" as it is the only way of meeting stringent emissions regulations in the future.
“We are planning to have a plug-in hybrid in each and every model series,” BMW’s head of production for large vehicles, Peter Wolf, told motoring.com.au. “So far we have the 3, 5 and 7 Series as full hybrids, and at the other end of the bookshelf the i3 and the i8. We are planning to work on that with the X5 eDrive, but at this stage, the plug-in is a completely new concept, and the battery is very specific .”
Diess explained that European customers are likely to see most of the new electric-drive technology first, as regulations here are stricter than elsewhere....

In 2008 they rated the proliferation risks of the:
Once-Through Fuel Cycle
in 6 categories.
The Full Actinide Recycle approach is rated in the category
"Fuel Cycle:Inherent proliferation risk of technology"
"Highest risk: Capable of separating weapons-usable material, though some modification may be needed depending on the separations technology used."
And in the category
Highest: Removal of fission products and separation of actinides greatly reduces barriers to theft, misuse, or further processing, even without separation of pure plutonium. Fast reactor fuels have higher concentration of weapons-usable materials.
For the category
Highest cost and difficulty: Separation processes require continuous monitoring against diversion and novel bulk materials present new measurement challenges.
Whose judgement is that?
National Nuclear Security Administration (NNSA)
"NNSA has the best science, technology and engineering in the world, and we are fortunate to have dedicated professionals who are truly leaders in their fields working every day to promote our nuclear security mission."
Can you believe the gall of those antinuclear idiots and the degree they've infiltrated the government?
