Geothermal Heats Up At The Geysers

Welcome to The Geysers

The Geysers, comprising 30 square miles along the Sonoma and Lake County border, is the largest complex of geothermal power plants in the world. Calpine, the largest geothermal power producer in the U.S., owns and operates 15 power plants at The Geysers with a net generating capacity of about 725 megawatts of electricity - enough to power 725,000 homes, or a city the size of San Francisco.

Click image to enlargeThe Geysers meets the typical power needs of Sonoma, Lake, and Mendocino counties, as well a portion of the power needs of Marin and Napa counties. In fact, The Geysers satisfies nearly 60 percent of the average electricity demand in the North Coast region from the Golden Gate Bridge to the Oregon border. The Geysers is one of the most reliable energy sources in California delivering extremely high availability and on-line performance and accounts for one-fourth of the green power produced in California.

Renewable Power Solutions Awarded First State of California-approved Exclusively Solar Apprenticeship Program

Exclusively Solar Apprenticeship Program in California

Renewable Power Solutions, Inc., a leading provider of solar energy installation services for residential, commercial, non-profit and governmental buildings, announced today that it has been awarded the first exclusively solar apprenticeship program by the State of California. The company has partnered with the San Jose Metropolitan Education District's Central County Occupational Center to organize the in-classroom portion of the program.

"As the renewable energy industry, and solar panel installations in particular, are poised for explosive growth in the years ahead, we felt it was necessary to address standards of workforce qualification and ultimately the quality of solar installations. These standards will provide the industry with the necessary and systematic training for a successful future of the solar workforce."
The State of California apprenticeship program allows for learning while earning, combining training on the job with related and supplemental instruction at school. The new program developed by Renewable Power Solutions provides accredited training to individuals seeking a career in the photovoltaic industry. The curriculum includes on-the-job learning, classroom teaching and homework. The program requires the successful completion of 4,000 hours to achieve photovoltaic journeyman status and will typically take up to two years to complete.

Glen Forman, acting chief of the Division of Apprenticeship Standards, added, "DAS offers an earn-while-you-learn model for talent development. It is an age-old solution to workforce training that fits for today's innovative businesses. Partnering with business, DAS creates standards to establish uniform skill sets for positions within an industry, helping to strengthen California's workforce."

According to John Fox, director of CCOC, "The Central County Occupational Center, a unit of the Metropolitan Education District, is looking forward to partnering with Renewable Power Solutions to serve as the Local Education Agency for the solar apprenticeship program."

Nuclear Dilemma

Saturday marks the anniversary of an event that changed the direction and history of American electricity generation. Thirty years ago, the nuclear power plant at Three Mile Island suffered a partial core meltdown in Unit 2 when a stuck valve allowed coolant to escape. The accident on March 28, 1979, sparked safety concerns that effectively shut down an industry many had touted as the answer to America's future energy problems. 

Since the TMI accident, only one nuclear power plant has been built in the United States. The high cost of building nuclear plants, coupled with concerns about their safety, made this futuristic technology all but extinct. But concerns about nuclear power are now being replaced by concerns about global warming.

A number of prominent scientists and politicians - including President Barack Obama - insist nuclear power must play a role if the United States is to wean itself from foreign oil and reduce carbon emissions. Nuclear already a plays a significant role in the production of electricity. Nearly 20 percent of the nation's electricity is produced by nuclear power plants; 34 percent of Pennsylvania's electricity supply is derived from nuclear power. In 2008, TMI's Unit 1 set an operating record.

A spokesman for the Nuclear Energy Institute said nuclear power plants are operating more efficiently than ever because of technical improvements in turbines and generators. To that end, TMI plans additional improvements, as evidenced by last week's announcement that Exelon, which now owns TMI, intends to install two new 510-ton generators. Nuclear power plants also are staying online longer than previously forecast. TMI is expected to apply for a permit extension to operate through 2034. 

Citing safety improvements and 30 years of accident-free domestic operation since TMI, proponents argue that nuclear power plants are safe. Nuclear and coal-powered plants supply nearly half of the nation's base-load electricity supply. If the United States is to meet reduced carbon emissions goals and expand electricity capacity, nuclear has to be part of the equation. Preparations are now being made to build four or more nuclear power plants within the next 10 years. Some of these plants are expected to be sited at existing facilities. Nuclear power generation is not carbon-free - it emits about one- fourth as much pollution as coal-fired plants. As the debate over greenhouse gases grows, however, nuclear power looks greener all the time. Surveys show that more than half the public favors building more nuclear power plants. Nuclear might have even greater support if not for the waste it produces. And that is what this debate ultimately must be about. Spent fuel rods have a radioactive half-life of hundreds of years. With the Obama administration's decision not to pursue Yucca Mountain, Nev., as a national repository for spent fuel rods, the question is where these rods will be stored. 

Currently spent fuel rods are stored in high-security casks at nuclear power plants. Although nuclear industry officials contend that the casks are safe, the fact that radioactive materials are stored at each of the 104 nuclear facilities in the country poses an enormous security risk. NEI officials say that removing Yucca Mountain from the discussions is sensible - that they now can look into alternatives such as regional repositories. Reprocessing the fuel, which could be used to generate additional energy, also is a possibility.

The promise posed by nuclear power generation - to supply much more of the nation's electricity while cutting carbon emissions - is enormous. But before that can happen, officials and politicians must craft a publically supportable permanent solution for the radioactive waste these plants produce. Until that occurs, this space-age technology will remain bottled up.

It happened 30 years ago: Three Mile Island accident

Three Mile Island accident

Three Mile Island 
Three Mile Island
A partial meltdown at the Three Mile Island nuclear plant near Harrisburg, PA, occurred thirty years ago today, on March 28, 1979. The cooling system in one of the nuclear reactors failed, causing overheating and a partial melting of the uranium core. Backlash from the incident brought protests and demonstrations against nuclear power; some 200,000 attended a rally in New York City. Nuclear plant production came to a halt in the US and the Nuclear Regulatory Commission established stricter guidelines and safety measures on the plants already in existence.

"None of us are nuclear experts, but we know that if there is a melt-down and breach of containment, that's clearly the most odious thing that could happen." — William Scranton 

Question of the Day

Can an improperly managed nuclear power plant explode like a nuclear weapon?
No, it cannot. No mismanaged nuclear plant, no nuclear plant accident of any kind, can cause a massive nuclear explosion like the blast of a nuclear weapon. To understand this, begin with the idea that fissionable material requires a certain minimum amount (critical mass) of it to be brought together to spontaneously initiate fission, to make it go critical. In a nuclear weapon, the subcritical masses are driven together and held together for an extremely short interval of time by conventional explosives. The result of driving and holding the critical mass together is that it goes critical and instantly right through that to supercritical. This causes the nuclear chain to build exponentially and the number of fissions per unit of time goes through the roof. Boooooom. Maximum fission burn and big yield. 

In a non-bomb situation, subcritical masses of fissionable material are brought together without being blasted together. They achieve criticality and fission begins instantly. Enough fissions will occur to generate enough heat to separate the critical mass to make the whole thing go subcritical. That will be the only goal of the fission reactions — to separate the critical mass into something subcritical. ... More

Gartner Says Too Many Enterprises Are in Denial About Carbon Management

Survey Indicates That Less Than 20 Per Cent of Enterprises Worldwide are Considering Carbon Pricing

A high proportion of IT professionals responsible for "green IT" programs are unsure whether their enterprises are considering carbon pricing, according to Gartner, Inc. A recent Gartner survey found that 36 per cent of respondents that were responsible for green IT programs in enterprises said it was possible, or they didn’t know, if carbon pricing was influencing their organization’s planning for the next 24 months.

A total of 45.7 per cent of respondents said that carbon pricing was not influencing their organizations planning, while 18.3 per cent said it was influencing their organization’s planning for the next 24 months.



The survey results indicate that for most countries, the percentage of enterprises planning ahead for carbon pricing goes beyond those obliged to consider it under established regulations. However, Gartner advised IT management teams that haven’t already done so, to start building the processes and information systems to gather the necessary data as this can be time-consuming and organizations are likely to be subject to carbon reporting and pricing in the future.

In an international survey completed in December 2008, Gartner asked 626 enterprises about their plans for carbon reporting and pricing, and current and future implementation of carbon reporting, tracking or management systems. The respondents represented an even spread of sectors and company sizes from 1,000 to more than 10,000 employees.

“While the number of enterprises using or planning to use carbon tracking systems exceeds those legally required to do so, given the inevitable requirements to support carbon reporting in the future, the percentage of enterprises preparing is low,” said Simon Mingay, research vice president at Gartner. “Regardless of actual or anticipated regulations, midsize and large enterprises should at least be building carbon information systems, because, whether in a developed or developing economy, pressure will come down the supply chain to be transparent about carbon emissions.”

The Obama administration is now talking about a carbon cap and trade scheme, along the lines of the EU ETC and Australian CPRS in which enterprises are obliged to buy and/or sell tradable carbon certificates —– trading at €12/metric tones as of March 2009, but anticipated to rise as carbon allowances get squeezed. This kind of scheme and others such as the U.K.’s Carbon Reduction Commitment result in a price being placed on a metric tones of carbon.

The survey provided some noteworthy responses from individual countries when respondents asked if the possibility of carbon pricing is influencing their organization’s planning for the next 24 months. The U.K. and France recorded some of the lowest percentages at 7.9 per cent and 10.5 per cent, respectively, while in India and China, 21.1 per cent and 20 per cent of enterprises, respectively, indicated that carbon pricing was influencing planning. Gartner analyst said this is particularly surprising for the U.K. given that the country’s Carbon Reduction Commitment (CRC) goes into effect in 2010 and is estimated to affect 5,000 enterprises.

Gartner also asked the same respondents about their carbon reporting, tracking and management systems, as well as their intentions to implement or extend such systems. The results showed that, as a region, Western Europe is best prepared, with 32 per cent saying that they have some kind of system in place — twice as many as the Asia/Pacific region or the U.S. However, there were some stark contrasts with 2.6 per cent of French enterprises, compared with 74.4 per cent of German enterprises having such systems in place. Most of those enterprises with systems in place had in-house developments (mostly spreadsheets).

A further question asked of the respondents was whether they would be implementing or extending carbon reporting, tracking or management software during the next 18 months. The results showed that most enterprises are not yet thinking about how carbon pricing or reporting requirements will affect their business and have no plans to implement a carbon reporting, tracking or management system to give them visibility of their greenhouse gas emissions in this period.

“This apparent lack of preparation, and the inevitability that most enterprises will come under increased scrutiny from customers, investors, partners, key stakeholders and, eventually, regulators, should come as a wake-up call to policymakers, boards, senior leadership teams and CIOs,” said Mr. Mingay.

Australia has made the most rapid progress overall in this area in the last 15 months, and Gartner expects that to continue during the next 18 months. The proportion of enterprises anticipating implementing carbon management tools during the next 18 months in the Europe, the Middle East and Africa (EMEA) region was low at 17 per cent and the U.S. was slightly more than 18 per cent.

“Enterprises all over the world need to get more serious about greenhouse gas reporting,” Mr. Mingay said. “Despite the lack of specific regulations, midsize and large enterprises in developed economies need to recognize that they will be paying for their emissions at some point — it’s just a matter of when, how much and through what kind of mechanism. Regardless of the recession, enterprises will find themselves under increasing pressure from stakeholders, including investors and customers, to be more transparent about emissions and reduction programs.”

G.E.’s Green Chief: Bullish on Clean-Tech Future

G.E.’s Green Chief: Bullish on Clean-Tech Future
Steve FludderLibrado Romero/The New York Times“We expect the demand for new orders is going to pick up in the near future,” said Steve Fludder, a G.E. vice president.

Steve Fludder, the vice-president of General Electric’s “Ecomagination” unit, which concentrates on developing green technologies, expressed optimism Wednesday that deals would start flowing again in the wake of the stimulus bill — but said that his business was still feeling the force of the financial crisis.

“I don’t think that we can declare victory per se,” Mr. Fludder said in an interview with Green Inc. and The New York Times.

The Ecomagination unit, which has been growing about 20 percent a year since its inception in 2005, and which currently pulls in annual revenue of $17 billion, will be hard-pressed to make its $25 billion target next year, Mr. Fludder indicated. “I think the $25 billion, which was a target that was set long before anybody knew this economic crisis was coming, is under pressure next year,” he said.

In the wind turbine business — an example of an industry hard hit by the crisis — the company has experienced a drop in demand for new orders, Mr. Fludder said, adding, “We expect the demand for new orders is going to pick up in the near future.”

Mr. Fludder also foresees growth potential in carbon capture and storage technologies, as well as nuclear power.

Coal will continue to be a major source of energy for some time, he said — and the technology for removing carbon emissions associated with coal-fired power is available. The issue, he said, is making it cost-effective. (Other experts have drawn similar conclusions.)

Mr. Fludder also foresees growth in the nuclear power business in the United States, despite the decades-long drought in new plants. “Look at what nuclear power provides,” he argued. “It provides energy independence; it provides cost-effective baseload power generation; and it provides carbon-free power.”

In the meantime, Mr. Fludder emphasized the importance of energy efficiency. The G.E. airplane engine that will go into the delayed Boeing 787 Dreamliner will be 14 percent more fuel-efficient than its predecessor, which is in the Boeing 767.

As for the most exciting addition to Ecomagination’s portfolio, Mr. Fludder singled out wastewater treatment technology — which provides homes and businesses with the ability to recycle wastewater and use it in toilets and on lawns (G.E. has such a system in place in a Battery Park apartment complex in New York City).

“I liked it so much I put one of those in my house,” he said.
