Ont. has $26B nuclear decision looming in 2009

Updated: Sat Dec. 27 2008 2:41:08 PM       ctv toronto.ca

 

Ontario has a $26-billion decision to make in 2009 -- Who will construct the province's next generation of nuclear electricity generating plants?

But to answer that key question, one must answer another: In a time of economic recession, should a priority be put on a bidder who will maximize the number of jobs in Ontario?

Three vendors are seeking the contract:

  • Westinghouse Electric Co., a U.S. nuclear giant
  • AREVA NP, a French company
  • Atomic Energy of Canada Ltd.

Ontario announced the following criteria when it announced its plans for more nuclear energy in mid-June:

  • Lifetime cost of power
  • Ability to meet Ontario's timetable to bring new supply on line in 2018
  • Level of investment in Ontario

A wild card is that AECL wants to sell Ontario a new breed of reactor, one that hasn't been tried anywhere in the world.

Critics of that proposal fret that the cost overruns could prove to be astronomical.

"The McGuinty government says $26 billion. You talk to people out there, they say start thinking in terms of $50 billion or $60 billion in terms of the final cost. So very expensive power," said NDP Leader Howard Hampton, who has written a book on nuclear energy.

Both Westinghouse and AREVA have proven technologies, which means more predictable costs, but much of the engineering and development work would be done in either the United States or France.

AECL would provide more jobs for Canadians.

"The stimulative effective of building a nuclear power plant is really quite extraordinary," Energy and Infrastructure Minister George Smitherman told CTV Toronto. "I think that the message there about investing in domestic infrastructure with a domestic company that's owned by the government of Canada, that point is well taken."

Smitherman has suggested he can't let the jobs question dictate his final choice, although he has asked the bidders to place an emphasis on creating jobs in Canada.

As evidence of the difficulty of the decision, the government has shifted its deadline for final bids several times.

The first one came in October, which was then pushed back to Dec. 31, and has now been set for sometime early in 2009.

After the October deadline passed, Smitherman said it was because of intense negotiations, mainly over getting private-sector bidders to agree to pay for any delays and cost overruns caused by factors under their control.

Ontario hopes to get 13,000 megawatts of electricity from nuclear energy, with the privately-operated Bruce Power providing an additional 6,300 MW.

Ontario can currently meet a peak load of just under 25,000 MW. The province wants to cut peak demand by 2,700 MW by 2010.

The new reactors will be built at the Darlington site in Durham region, which has been left reeling by the economic troubles of General Motors Canada Inc., the city's main employer.

Darlington became synonymous with massive cost overruns when it was constructed almost 20 years ago. However, the nuclear industry has said construction techniques have improved and that all bidders have completed their recent projects on time and on budget.

Nuclear commission ponders future of Pickering power plant 

http://www.waterkeeper.ca/2008/12/29/nuclear-commission-ponders-future-of-pickering-power-plant/

December 29, 2008

The final Environmental Assessment report on the Pickering nuclear power plant is in, and the Canadian Nuclear Safety Commission (CNSC) is now considering whether or not to permit a life extension for one of the world’s largest nuclear power generating facilities.

“If the nuclear safety commissioners want to refurbish Pickering, they need to launch a full-scale review panel,” Lake Ontario Waterkeeper Mark Mattson told the CNSC at a hearing in Ajax December 10th. In his presentation, Mattson highlighted some of the potential environmental impacts of continuing the operation of Pickering, including:

The Pickering nuclear power plant already contributes to the deaths of millions of fish each year by trapping fish and destroying fish eggs in its cooling system.

The hot water discharged from the plant into Lake Ontario disrupts fish habitat, encourages the growth of algae, reduces drinking water supply quality, and impedes swimming and boating.

Mattson also expressed concerns about the process for approval. The screening-level assessment offers the lowest level of scrutiny possible.

The CNSC:

  • Limited presentations from the public to 10 minutes
  • Did not require experts to testify under oath, or to be cross-examined
  • Did not require OPG and CNSC staff to consider alternatives to nuclear power generation

In comparison, both the Bruce and Darlington plants are subject to the review panels process.

“When these nuclear facilities were first constructed, there was no Environmental Assessment process,” says Mattson. “Now, we have this planning tool, and we are not using it properly. This is our last chance to make an informed decision about the future of this nuclear power plant. Lake Ontario and its communities can’t afford another mistake.”

The Pickering “B” generating station consists of four CANDU reactors now reaching the end of their life cycles. Ontario Power Generation applied to the CNSC for permission to rebuild the aging reactors and extend their lives through to 2060. The proposal must pass a mandatory Environmental Assessment before receiving CNSC approval.

Is reviving aging energy technology the right choice in a changing world?

 

The lepreau factor

 

The Telegraph Journal;  Published Saturday December 27th, 2008

Projects As NB Power looks to move further next year from a reliance on fossil fuels to generate electricity, the bedevilled refurbishment of the utility's nuclear plant is the foremost concern of CEO David Hay  A1   Rob Linke   Telegraph-Journal

Ask David Hay, president and CEO of NB Power, what's on his mind when he thinks about the year 2009 and he answers without hesitation.

NB Power president and CEO David Hay will know sometime in January whether the $1.4-billion refurbishment of the nuclear reactor at the Point Lepreau Nuclear Generating Station will miss its deadline.

His three rapid-fire words: "Lepreau, Lepreau, Lepreau."

Sometime in January, Hay will know whether the $1.4-billion refurbishment of the nuclear reactor at the Point Lepreau Nuclear Generating Station will miss its September 2009 deadline because of trouble the main contractor, Atomic Energy of Canada Ltd., had with automated tooling in the summer and fall of 2008.

Hay revealed in October that the delays had eaten up all the leeway planners built into the schedule. Teams of engineers have since been studying how to make up time.

The pressure is on.

"What's at stake for NB Power?" Hay asks rhetorically. "First and foremost, it's doing what we said we would do. The premier and government of the day approved a plan. If we come in late, it's not what we said we would do."

New Brunswick won't be without electricity if the Lepreau refurbishment misses its deadline.

Neither will ratepayers or taxpayers be on the hook. Under the terms of its contract, AECL will have to absorb cost overruns - including replacement power, which can cost $1-million a day.

But as long as safety isn't compromised, Hay would love nothing more than to tell New Brunswickers and the energy world that Lepreau will be on-time and under-budget.

"We want to show the world we are the little engine that could - the smaller utility that can achieve what so many others have failed to do," he says.

Hay and Energy Minister Jack Keir have pointed to an on-time, on-budget completion of the refurbishment as a prerequisite for a go-ahead on a second reactor proposed for Lepreau by AECL and its private-sector partners.

For most of 2008, Keir's department has been reviewing two feasibility studies into what could be a $4-billion project that would eventually be operated by NB Power. Proponents of a second reactor said months ago they have lined up investors willing to pay for the estimated $50-million cost of a three-year licensing application and environmental review.

But apart from these developments, the second reactor scenario has been quiet for months.

Hay says he and his staff are convinced that some day, a second reactor will hum away at Lepreau - but he confesses he has no idea whether 2009 will hold a go-ahead announcement.

"I really don't know," he says. "Even six months ago, it was hard to think of financing something on this scale.

"Today, with the global credit crunch, it would be pretty darn hard, or the price of that capital would be pretty high."

The AECL-private consortium Team Candu is still hunting for an equity partner with the experience, access to capital and interest in making a long-term investment, he says.

Even without a second reactor, Lepreau's return to service will propel NB Power down a path it has been on for some time: decreased reliance on fossil fuels to generate electricity.

In 2000, NB Power would have generated 10 megatonnes of greenhouse gas emissions. That's now down to six megatonnes, and once a refurbished Lepreau and more of the wind farms coming online are running, it could be down to four megatonnes.

NB Power executives are also dusting off and updating old analyses of how much untapped potential the St. John River has to generate electricity from hydro power.

The effort is part of the integrated resource plan the government asked NB Power to prepare.

The utility is still a long way from deciding if, when or where it may build another dam, but looking ahead, Hay sees a continuing move away from fossil fuels.

In 2009, "I think everyone from the prime minister on down is going to be looking south" to see what the Obama administration does to cap carbon emissions, he says.

Still, in the topsy-turvy world of energy prices, moving away from fossil fuels won't necessarily increase NB Power's ability to hold the line on rates.

Oil prices have plummeted to just over a quarter of the record highs they reached last summer.

In mid-December, it was cheaper to run Coleson Cove than to buy electricity from a wind farm.

Hay makes no prediction about rates in 2009.

Instead, he articulates a principle.

"Power rates have generally gone up and it is incumbent on all of us to pay for what we use," he says. "The alternative is to leave unpaid costs to future customers.

"That said, our job at the utility is to provide the cheapest electricity we can without compromising safety or the environment."

NB Power certainly faced challenges in 2008, including a brouhaha that erupted in the legislature over bonuses paid its board members and new turbines for Lepreau that fell off a barge into Saint John harbour.

And although Hay expresses confidence the Lepreau refurbishment will be completed on time and on budget, meeting that goal remains a worry.

Still, NB Power did de-fuel and de-water Lepreau on time and on budget (the first two months of the refurbishment were the utility's responsibility before it handed the project over to AECL).

And after severe spring flooding damaged the Grand Falls generating station, the team that brought it back online did so six weeks earlier than planned.

"Looking back, 2008 was a great year operationally," Hay says.

That confidence in his people - and a sense of unfinished business with Lepreau - has Hay eager to renew his five-year contract, which is up in March.

"Things are going well and I want to do the right thing," he said

 

Russian Regulators Warn Nuclear Safety Undercut by Economic Crisis

Environment News Service; MOSCOW, Russia, December 24, 2008 (ENS)

The safety of Russia's nuclear industry is being negatively affected by the country's economic crisis and the situation is expected to to worsen in 2009, according to a newly released annual report by the Russian nuclear regulatory body Rostekhnadzor.

Ongoing job cuts at nuclear facilities include the personnel directly responsible for safety control, states the report by Rostekhnadzor, which is responsible for licensing and safety at Russia's 31 operating nuclear power plants and the eight more under construction.

Activists with Ecodefense are calling on the Russian government to quickly adopt a plan to insure public safety and nuclear security.

"Ecodefense urges Russian government to quickly develop and adopt a plan to avoid possible accidents at nuclear facilities resulting from safety staff cuts and the general economic decline. The prevention of nuclear proliferation must be part of this plan," said Vladimir Slivyak, co-chairman for Ecodefense, 

a Russian nuclear watchdog group established in 1989.

"Otherwise, Russia may return to the dark days of the 1990s when unemployed nuclear scientists and technical specialists were offering services to anyone who able to pay. At the same time there was a 

developing market for illegal nuclear materials across the country," said Slivyak.
According to the government report, obtained by Ecodefense, staff cuts have been underway since 2007.

Rostekhnadzor reports that there have been "job cuts at facilities responsible for nuclear-fuel cycle of personnel responsible for safety control and maintenance."

The report also criticizes nuclear facilities management for "not paying enough attention to ensuring nuclear safety."

In a criticism of itself, Rostekhnadzor reports that it doesn't have enough safety inspectors to do its own job properly.

"It is possible that further cut jobs in Russia may bring back the nuclear proliferation problems related to illegal trade of radioactive materials," Slivyak cautioned. "These radioactive materials can be used for building a dirty bomb."

The deteriorating social and economic situation in Russia is likely to result in significant drop of nuclear safety level at many nuclear facilities. Some nuclear facilities have already seen jobs cut because of reduced national income due to declining oil prices and the global recession.

Russia is in deep economic trouble with the myriad of unsolved problems in nuclear power industry.

One problem with both public health and economic implications is the growing amounts of radioactive waste of various types, including uranium tailings and spent nuclear fuel stored throughout the country.

The Rostekhnadzor report warns that there is "significant risk" of the containers breaking open and leaking the uranium tailings inside - radioactive and highly toxic waste resulting from uranium enrichment.

These wastes are stored near several large cities like Ekaterinburg, Tomsk, Krasnoyarsk and Irkutsk, the location of the so-called International Uranium Enrichment Center established by Rosatom, the Russian state nuclear corporation.

According to independent estimates, there are over 700.000 tons of uranium tailings stored across Russia in very poor condition with high risk of radioactive and toxic leakages to the environment.

All across the country, the amount of radioactive waste is growing; it is kept in inadequate storage mostly built decades ago in the beginning of nuclear industry history.

These containers do not meet current safety standards for long-term storage, according to the regulators in their report.

In the case of spent fuel, Rostekhnadzor states there are "unresolved issues" such as large amounts of spent nuclear fuel in reactor pools and limited free space at several nuclear power plants - mostly Leningrad's and Kursk's with RBMK reactors, the same type of reactor as the one that caught fire and exploded at Chernobyl on April 26, 1986 in the world's worst nuclear accident.

Ecodefense is concerned that the socio-economic decline may worsen existing problems and lead to new radioactive contamination in many places across Russia, saying, "The government must start to work now in order to avoid new nuclear accidents in the future."

Requests for a moratorium on military use

http://en.wikipedia.org/wiki/Depleted_uranium  (significant references on website)

Some states and the International Coalition to Ban Uranium Weapons, a coalition of more than 100 non-governmental organizations, have asked for a ban on the production and military use of depleted uranium weapons.[35]

The European Parliament has repeatedly passed resolutions requesting an immediate moratorium on the further use of depleted uranium ammunition,[36][37] but France and Britain – the only EU states that are also permanent members of the United Nations Security Council – have consistently rejected calls for a ban,[38] maintaining that its use continues to be legal, and that the health risks are entirely unsubstantiated.[39]

France, Britain, the Netherlands, and the Czech Republic voted against a United Nations General Assembly resolution to hold a debate in 2009 about the effects of the use of armaments and ammunitions containing depleted uranium in 2009. All other European Union nations voted in favour or abstained.[40] The ambassador from the Netherlands explained his negative vote as being due to the reference in the preamble to the resolution "to potential harmful effects of the use of depleted uranium munitions on human health and the environment [which] cannot, in our view, be supported by conclusive scientific studies conducted by relevant international organizations."[41] None of the other permanent members of the United Nations Security Council supported the resolution as China was absent for the vote, Russia abstained and United States voted against the resolution.[40]

In September 2008, and in response to the the 2007 General Assembly resolution, the UN Secretary General published the views of 15 states alongside those of the IAEA and WHO. The IAEA and WHO evidence differed little from previous statements on the issue.[42] The report was largely split between states concerned about DU's use such as Finland, Cuba, Japan, Serbia, Argentina and Qatar and predominantly NATO members such as Spain and the Netherlands who do not consider the use of DU munitions problematic.[citation needed]

In December 2008 the United Nations General Assembly passed by 141 votes to four (with 34 abstentions) a resolution requesting the IAEA, WHO and UNEP to update their positions on the potential impact of uranium weapons on human health and the environment. The issue of uranium weapons will return to the General Assembly in 2010. The resolution was notable in that EU and NATO states that had previously abstained on the issue such as Norway and Finland voted in favour, as did the Netherlands, who in 2007 voted against a resolution highlighting health concerns over the weapons.

WASHINGTON, Dec 17 (OneWorld.net) - "At a time when major U.S. companies are announcing job layoffs almost daily, the renewable energy industry is hiring new workers every day to build wind farms, install rooftop solar arrays, and build solar thermal and geothermal power plants," writes environmental expert Lester Brown.

·         The "explosive" growth in the United States of wind, solar, and geothermal energy means increased energy security, stabilized energy prices, and thousands of new jobs, writes environmental expert Lester Brown, president of the Earth Policy Institute. © Taylor Dundee (Flickr)Brown, who has been called "one of the world's most influential thinkers," notes that while every $1 billion invested in coal-fired power plants generates some 870 jobs, the same investment in wind energy technologies would produce 3,350 jobs, with similar results for investments in solar-thermal power plants (2,270 jobs) and solar cell installations (1,480 jobs) on rooftops and other locations. Brown also estimates that $100 billion of government investment in renewable energy and energy efficiency projects would leverage $400 billion in private investments, and that a $500 billion federal investment over the next 12 years could leverage enough money to help cut global greenhouse gas emissions sufficiently to stave off the melting of the Greenland ice cap and other key glaciers that sustain lives and livelihoods around the planet. (Read Brown's entire analysis below.)

·         Two other studies released recently also argued that worldwide efforts to overcome the current economic crisis will require more spending on green industry, which will in turn help slow and possibly reverse the impending climate crisis. Statistical analysis in the report "Green Jobs: Working for People and the Environment," by the environmental think tank Worldwatch Institute, shows that nearly 200 million people in the world currently have no work to make their ends meet. In China alone, however, renewable energy technologies employ no less than 1 million people in the wind, solar, and biomass industries. Meanwhile, retrofitting Europe's residential buildings in order to cut carbon emissions by 75 percent, could lead to more than 2 million new jobs in the next two decades, states the report.

·         In the United States, the new administration has proved a source of hope for environmentalists and the unemployed alike. According to his Web site, President-elect Barack Obama will "help create 5 million new jobs by strategically investing $150 billion over the next 10 years to catalyze private efforts to build a clean energy future." Obama has also pledged to cut greenhouse gases by 80 percent by 2050 and ensure that 25 percent of all electricity consumed in the United States comes from renewable sources by 2025. 

 

Creating New Jobs, Cutting Carbon Emissions, and Reducing Oil Imports by Investing in Renewable Energy and Energy Efficiency

http://www.celsias.com/article/creating-jobs-cutting-emissions-reducing-oil-impor/

From: Earth Policy Institute    December 11, 2008     Lester R. Brown

At a time when major U.S. companies are announcing job layoffs almost daily, the renewable energy industry is hiring new workers every day to build wind farms, install rooftop solar arrays, and build solar thermal and geothermal power plants. The output of industrial firms that manufacture the equipment for these energy facilities is expanding by well over 30 percent a year. These investments both create jobs and help prevent climate change from spiraling out of control.
Among the several sources of renewable energy, wind looms large. The United States has 24,000 megawatts of wind generating capacity already online (think 24 coal-fired power plants), and 83 wind farms with some 8,000 megawatts of capacity are under construction. Beyond this, a staggering 225,000 megawatts of planned wind farms are waiting for access to transmission lines.
Currently, the United States has 40 plants manufacturing wind power components. Eight of these plants are assembling wind turbines, 20 are fabricating wind towers, and 12 are making blades. In addition, many more manufacturing facilities are under construction, recently announced, and in planning. Every billion dollars invested in wind farms creates some 3,350 jobs—nearly four times the 870 jobs created with a similar investment in coal-fired power plants. (See data
.)
With solar cells (photovoltaics), the U.S. growth potential can be seen in the recent expansion from small rooftop installations to commercial generating facilities covering several square miles. In 2007, the United States installed roughly 200 megawatts of solar cell generating capacity, most of it on rooftops. In 2008, Pacific Gas & Electric—a leading California utility—contracted with two firms to build 800 megawatts of solar photovoltaic generating capacity; their output at peak power will equal that of a nuclear reactor. A billion dollars invested in solar cell installations generates 1,480 jobs.
A similar growth situation exists with solar thermal power plants—facilities that use mirrors to concentrate sunlight and generate steam to power turbines. Until recently there was just one of these facilities in the United States: the 350-megawatt SEGS complex in California. Now there are 18 commercial-scale power plants under development (15 in California, 2 in Florida, and 1 in Arizona) with a collective generating capacity of 4,160 megawatts—nearly a twelvefold increase. This is an example of yet another labor-intensive energy technology (2,270 jobs per billion dollars invested) with a sharply falling cost curve that is fast becoming a major player in the U.S. energy economy.   
Next consider geothermal energy. For 20 years, the United States had only one commercial-scale geothermal generating facility, in California. Now suddenly, almost overnight, there are some 96 projects—most of them with a generating capacity ranging from 10 to 350 megawatts—in western states. We are witnessing the emergence of a major new source of electricity.
Two new technologies—plug-in hybrid cars and advanced design wind turbines—have set the stage for building an entirely new automotive fuel economy. While four manufacturers are coming to market with plug-in hybrids in 2010 or 2011, the early estimates of how many they will produce appear to be small. What is needed is a crash program, almost a World War II–type mobilization, to produce tens of millions of cars powered largely with electricity, mostly from wind farms, at the gasoline equivalent cost of less than $1 per gallon. The good news is that plug-in hybrids do not need a new infrastructure.
The U.S. goal for Detroit should be not merely to save it but to make it the world leader in producing high-efficiency plug-in hybrid cars. Replacing one gas-guzzling SUV with a plug-in hybrid will, over the car’s lifetime, reduce oil imports by 200 barrels, saving $20,000 of oil imports. Such an initiative multiplied across the fleet would keep hundreds of billions of dollars at home for job-creating U.S. investments.
Another job-creating way to save energy is to invest in urban transit, both light rail and buses. When combined with making streets bicycle- and pedestrian-friendly, this also increases mobility and reduces oil imports.
In terms of job creation, investment in retrofitting buildings creates more than seven times as many jobs as a similar investment in coal-fired power plants. One of the early leaders is Houston, which plans to retrofit each of its 271 government buildings, thus simultaneously reducing energy use and operational costs. As Houston Mayor Bill White says, “It makes good business sense.”
In California, Adobe Systems, a software firm, retrofitted its expansive corporate headquarters at a cost of $1.4 million, dropping its electricity use 35 percent and its natural gas use 41 percent. The energy savings paid back the $1.4 million retrofit investment in just 14 months. (More typically, the payback time on retrofitting buildings is closer to 5 years.) And these jobs cannot be outsourced.
Building the new energy economy creates jobs in the construction of wind farms or the retrofitting of buildings, and also indirectly in the supply lines that provide, for example, the parts for wind turbines or the thermally efficient windows for retrofitting. These investments also generate jobs outside the energy sector. For example, the construction of a wind farm in a Great Plains community generates jobs in local businesses such as restaurants and home improvement outlets.
The government’s role in this vast job creation initiative is to use public funds as incentives to leverage far greater investments of private capital. We estimate that $100 billion of federal funds used strategically over the next 12 years would leverage $400 billion of private capital investment. If this $500 billion is allocated evenly between renewable energy development (wind, solar, and geothermal) and retrofitting, and if every two jobs created in the energy sector creates one job elsewhere, this would quickly generate 600,000 new jobs that would last through 2020.
In addition to the short-term need to create jobs, there is the all-encompassing need to avoid runaway climate change and the threat it poses to global civilization. If the world is to have a decent chance of saving the Greenland ice sheet and at least the larger glaciers in the Himalayas and on the Tibetan Plateau, the glaciers whose ice melt sustains the major rivers and irrigation systems of Asia during the dry season, then global carbon emissions need to be cut 80 percent by 2020. For the United States, this might require up to $500 billion of federal funds to mobilize $2 trillion of private capital—for a total $2.5-trillion investment in renewables and efficiency by 2020. Investment at this level would create 3 million new jobs that would last through 2020.
A complementary measure to accelerate carbon reduction would be to incorporate the cost of climate change in fossil fuel prices either through a cap-and-trade system or by restructuring taxes. The latter would mean simply raising the tax on carbon and offsetting it with a reduction in income taxes. Both these measures shift investments from fossil fuels to efficiency and renewables.
One of the glaring gaps in current U.S. policy is the failure to extend the wind production tax credit beyond one year. The time has come to extend it to 2015, giving investors the needed confidence to make longer-term investments in both wind generation and transmission lines.
Beyond this, a strong national electricity grid is needed. Such a grid would both permit more-efficient management of the country’s electrical generating capacity and link regions rich in wind, solar, and geothermal energy with population centers.

Historically, it is rare for so many emerging threats to have a common solution. The measures described here would simultaneously reduce carbon emissions, lower oil imports, and create millions of new jobs. This is a win-win-win opportunity that we cannot pass by.

Wind, Water and Sun Beat Biofuels, Nuclear and Coal for Energy Generation, Study Says

http://www.renewableenergyworld.com/rea/news/story?id=54292

December 17, 2008

Wind power is the most promising alternative source of energy, according to Mark Jacobson.

by Louis Bergeron, Stanford News Writer California, United States [RenewableEnergyWorld.com]

The best ways to improve energy security, mitigate global warming and reduce the number of deaths caused by air pollution are blowing in the wind and rippling in the water, not growing on prairies or glowing inside nuclear power plants, says Mark Z. Jacobson, a professor of civil and environmental engineering at Stanford.

"That is exactly the wrong place to be spending our money. Biofuels are the most damaging choice we could make in our efforts to move away from using fossil fuels. We should be spending to promote energy technologies that cause significant reductions in carbon emissions and air-pollution mortality, not technologies that have either marginal benefits or no benefits at all."
-- Mark Z. Jacobson, Professor, Civil and Environmental Engineering, Stanford University

And "clean coal," which involves capturing carbon emissions and sequestering them in the earth, is not clean at all, he asserts.

Jacobson has conducted the first quantitative, scientific evaluation of the proposed, major, energy-related solutions by assessing not only their potential for delivering energy for electricity and vehicles, but also their impacts on global warming, human health, energy security, water supply, space requirements, wildlife, water pollution, reliability and sustainability. His findings indicate that the options that are getting the most attention are between 25 to 1,000 times more polluting than the best available options. The paper with his findings will be published in the next issue of Energy and Environmental Science and is available online here. Jacobson is also director of the Atmosphere/Energy Program at Stanford.

"The energy alternatives that are good are not the ones that people have been talking about the most. And some options that have been proposed are just downright awful," Jacobson said. "Ethanol-based biofuels will actually cause more harm to human health, wildlife, water supply and land use than current fossil fuels." He added that ethanol may also emit more global-warming pollutants than fossil fuels, according to the latest scientific studies.

The raw energy sources that Jacobson found to be the most promising are, in order, wind, concentrated solar (the use of mirrors to heat a fluid), geothermal, tidal, solar photovoltaics (rooftop solar panels), wave and hydroelectric. He recommends against nuclear, coal with carbon capture and sequestration, corn ethanol and cellulosic ethanol, which is made of prairie grass. In fact, he found cellulosic ethanol was worse than corn ethanol because it results in more air pollution, requires more land to produce and causes more damage to wildlife.

To place the various alternatives on an equal footing, Jacobson first made his comparisons among the energy sources by calculating the impacts as if each alternative alone were used to power all the vehicles in the United States, assuming only "new-technology" vehicles were being used. Such vehicles include battery electric vehicles (BEVs), hydrogen fuel cell vehicles (HFCVs), and "flex-fuel" vehicles that could run on a high blend of ethanol called E85.

Wind was by far the most promising, Jacobson said, owing to a better-than 99 percent reduction in carbon and air pollution emissions; the consumption of less than 3 square kilometers of land for the turbine footprints to run the entire U.S. vehicle fleet (given the fleet is composed of battery-electric vehicles); the saving of about 15,000 lives per year from premature air-pollution-related deaths from vehicle exhaust in the United States; and virtually no water consumption. By contrast, corn and cellulosic ethanol will continue to cause more than 15,000 air pollution-related deaths in the country per year, Jacobson asserted.

Because the wind turbines would require a modest amount of spacing between them to allow room for the blades to spin, wind farms would occupy about 0.5 percent of all U.S. land, but this amount is more than 30 times less than that required for growing corn or grasses for ethanol. Land between turbines on wind farms would be simultaneously available as farmland or pasture or could be left as open space.

Indeed, a battery-powered U.S. vehicle fleet could be charged by 73,000 to 144,000 5-megawatt wind turbines, fewer than the 300,000 airplanes the U.S. produced during World War II and far easier to build. Additional turbines could provide electricity for other energy needs.

"There is a lot of talk among politicians that we need a massive jobs program to pull the economy out of the current recession," Jacobson said. "Well, putting people to work building wind turbines, solar plants, geothermal plants, electric vehicles and transmission lines would not only create jobs but would also reduce costs due to health care, crop damage and climate damage from current vehicle and electric power pollution, as well as provide the world with a truly unlimited supply of clean power."

Jacobson said that while some people are under the impression that wind and wave power are too variable to provide steady amounts of electricity,  his research group has already shown in previous researach that by properly coordinating the energy output from wind farms in different locations, the potential problem with variability can be overcome and a steady supply of baseline power delivered to users.

Jacobson's research is particularly timely in light of the growing push to develop biofuels, which he calculated to be the worst of the available alternatives. In their effort to obtain a federal bailout, the Big Three Detroit automakers are increasingly touting their efforts and programs in the biofuels realm, and federal research dollars have been supporting a growing number of biofuel-research efforts.

"That is exactly the wrong place to be spending our money. Biofuels are the most damaging choice we could make in our efforts to move away from using fossil fuels," Jacobson said. "We should be spending to promote energy technologies that cause significant reductions in carbon emissions and air-pollution mortality, not technologies that have either marginal benefits or no benefits at all."

"Obviously, wind alone isn't the solution," Jacobson said. "It's got to be a package deal, with energy also being produced by other sources such as solar, tidal, wave and geothermal power."

During the recent presidential campaign, nuclear power and clean coal were often touted as energy solutions that should be pursued, but nuclear power and coal with carbon capture and sequestration were Jacobson's lowest-ranked choices after biofuels. "Coal with carbon sequestration emits 60- to 110-times more carbon and air pollution than wind energy, and nuclear emits about 25-times more carbon and air pollution than wind energy," Jacobson said. Although carbon-capture equipment reduces 85-90 percent of the carbon exhaust from a coal-fired power plant, it has no impact on the carbon resulting from the mining or transport of the coal or on the exhaust of other air pollutants. In fact, because carbon capture requires a roughly 25-percent increase in energy from the coal plant, about 25 percent more coal is needed, increasing mountaintop removal and increasing non-carbon air pollution from power plants, he said.

Nuclear power poses other risks. Jacobson said it is likely that if the United States were to move more heavily into nuclear power, then other nations would demand to be able to use that option.

"Once you have a nuclear energy facility, it's straightforward to start refining uranium in that facility, which is what Iran is doing and Venezuela is planning to do," Jacobson said. "The potential for terrorists to obtain a nuclear weapon or for states to develop nuclear weapons that could be used in limited regional wars will certainly increase with an increase in the number of nuclear energy facilities worldwide." Jacobson calculated that if one small nuclear bomb exploded, the carbon emissions from the burning of a large city would be modest, but the death rate for one such event would be twice as large as the current vehicle air pollution death rate summed over 30 years.

Finally, both coal and nuclear energy plants take much longer to plan, permit and construct than do most of the other new energy sources that Jacobson's study recommends. The result would be even more emissions from existing nuclear and coal power sources as people continue to use comparatively "dirty" electricity while waiting for the new energy sources to come online, Jacobson said.

Jacobson received no funding from any interest group, company or government agency.

Energy and vehicle options, from best to worst, according to Jacobson's calculations:

[GLOSSARY OF ACRONYMS:  CSP = concentrated solar power;  CCS = carbon capture and sequestration; BEV = battery electric vehicle;  HFCV = hydrogen fuel cell vehicle;  E85 = a specific high blend of ethanol]

Best to worst electric power sources:

1. Wind power 2. concentrated solar power (CSP) 3. geothermal power 4. tidal power 5. solar photovoltaics (PV) 6. wave power 7. hydroelectric power 8. a tie between nuclear power and coal with carbon capture and sequestration (CCS).

Best to worst vehicle options:

1. Wind-BEVs (battery electric vehicles) 2. wind-HFCVs (hydrogen fuel cell vehicles) 3.CSP-BEVs 4. geothermal-BEVs 5. tidal-BEVs 6. solar PV-BEVs 7. Wave-BEVs 8.hydroelectric-BEVs 9. a tie between nuclear-BEVs and coal-CCS-BEVs 11. corn-E85 12.cellulosic-E85.

Hydrogen fuel cell vehicles were examined only when powered by wind energy, but they could be combined with other electric power sources. Although HFCVs require about three times more energy than do BEVs (BEVs are very efficient), HFCVs are still very clean and more efficient than pure gasoline, and wind-HFCVs still resulted in the second-highest overall ranking. HFCVs have an advantage in that they can be refueled faster than can BEVs (although BEV charging is getting faster). Thus, HFCVs may be useful for long trips (more than 250 miles) while BEVs more useful for trips less than 250 miles. An ideal combination may be a BEV-HFCV hybrid.

(Nuclear Waste) Where Does It All Go?

NEW YORK TIMES EDITORIAL     Published: December 20, 2008

Tens of thousands of tons of spent fuel and military waste have been piling up at temporary storage sites around the country while the federal government has struggled, unsuccessfully, to find a long-term solution.

Expert groups have long recommended that the nuclear waste should be buried deep underground in a stable, leak-resistant geological formation that would keep it bottled up for many millenniums. Yucca Mountain, the only site now under consideration, has run into so many technical problems and so much political opposition that its future is uncertain. The site is still awaiting licensing from the Nuclear Regulatory Commission.

In the 1980s when Congress ordered the Energy Department to look for places to bury long-lived radioactive wastes, it visualized two underground repositories — one in the West and one in the East — to spread the burden fairly. Congress eventually chose one site in Nevada, which lacked the political clout at the time to push it elsewhere.

The only concession to Nevada was that no more than 70,000 metric tons could be stored at Yucca Mountain until a second repository was in operation. The amount of spent reactor fuel and military waste now stored at production sites and waiting for permanent disposal is expected to reach that limit by 2010.

The Energy Department now has recommended that the statutory limit be eliminated so that consideration of a second repository can be deferred. Without specifying any particular capacity, the report notes that Yucca Mountain could physically accommodate at least three times the statutory limit.

It would make sense to expand Yucca Mountain rather than undertake the arduous and controversial process of evaluating sites in other states. The political tides are running against the Yucca Mountain site. During a primary debate in Las Vegas, Barack Obama pledged to Nevada voters that he would “end the notion of Yucca Mountain.” His choice for energy secretary, Steven Chu, is also unenthusiastic.

A currently powerful Nevada Congressional delegation, led by its United States senators — Democrat Harry Reid, the majority leader, and John Ensign, the fourth-ranking Republican — also is pushing to kill off the project.

Our hope is that opponents of the repository will wait for a verdict from the Nuclear Regulatory Commission before prejudging the site as unacceptable. Nuclear waste is piling up and the country needs to find a safe place to store it.
