Update – The debate about this phenomena continues.  See compilation of further ruminations about continued available petroleum and climate from a variety of powerful voices in another post from June 11, 2012.  And some of the same ideas are chewed on in an interesting op-ed by Reuters editor Chrystia Freeland in the August 9, 2012 New York Times.

In 1991 Daniel Yergin published his massive history of the petroleum industry, The Prize: The Epic Quest for Oil, Money and Power. Regardless of what you think about Yergin’s perspective on the topic, it is hard to dispute the complete and authoritative nature of that book. It provided a guided tour through the life of one of the defining industries of the 20th century and remains a powerful and surprisingly readable look at this essential subject.

In the years that followed there was strong interest in an update to The Prize that brought the story up towards the present and grappled with challenges to the ascendancy of petroleum in our economy and society – like the realization that global warming caused by burning fossil fuels is causing deep and systemic damage to the planet.

In 2011 Doctor Yergin did produce that much awaited sequel, The Quest: Energy, Security and the Remaking of the Modern World. That book contains six full chapters detailing the evolution of modern climate science and leaves no doubt about the fundamental validity of the observation that the phenomena of global warming from the burning of petroleum and other fossil fuels is indeed, very real.

However, that point must play out against the backdrop of Dr. Yergin’s deep and abiding belief that the there is no such thing as “peak oil” – that global oil production may plateau and stop rising but that improvements in technology mean that we will never see a steep decline in exploitable oil reserves. Indeed, he is even more firm in his belief that if you look at the broader array of fossil hydrocarbons, including natural gas, that the progression of technologies like hydraulic fracturing and its deployment across the world will lead to continued availability of such fuels at fairly low prices for the long term – really, he argues, indefinitely. This is a hard perspective for a climate advocate to ponder – he is in effect arguing that continued availability of hydrocarbons is an “inconvenient truth” that those addressing the challenge of global warming must face, that the argument that “we are running out of the stuff anyway” is simply not part of the debate about continued use of fossil fuels.

But Dr. Yergin has his own dilemma to confront: he does not address the fundamental collision between his observations about the validity of climate science and his belief that we are not in danger of running out of affordable hydrocarbons. This is an especially difficult circle for him to square as he is fundamentally an optimist – believing that society has always found technological solutions to the problems we have encountered and created for ourselves in the past and we will do so again. To Dr. Yergin’s credit he does engage renewable energy and energy efficiency, the  key tools for decarbonizing our economy, at  length in The Quest but never quite gets to the point of describing a path to a future where we are no longer burning fossil fuels and putting greenhouse gases into the atmosphere.

It would be very difficult for Dr. Yergin to fully confront the dilemma implicit in his work – that the presence of affordable hydrocarbons (oil and/or natural gas) for indefinite future will create a strong pull constantly moving us away from making the reductions in our greenhouse gas emissions that science tells us we need to make in order to save ourselves.

Bill McKibben has noted on many occasions, getting off fossil fuels will be the hardest thing that humanity has ever done and the only thing that would be harder would be living in the world where we don’t. And Dr. Yergin is telling us that his expert analysis is that it will be even harder than many believe to make that transition because new technologies and techniques will continue to increase the pool of available fossil fuels – but he has looked at the climate science and he does not deny that we must make the transition.

In conjunction with the film’s New Hampshire tour, CLF co-hosted a successful webinar last week on the environmental and energy implications of importing more large-scale hydropower into New England. During the webinar, Nicolas shared a preview of Seeking the Current, and participants learned how the issues raised by the film are critical to a full understanding of proposals to import more hydropower, including the Northern Pass project. You can download an audio-visual archive of the webinar at this link (~100 MB .wmv file; Windows compatible only).  To play the webinar, you may need to download some additional software, which you can access here.

Thanks to our many terrific co-sponsors (all of which are noted here) and the extraordinary people who helped bring Seeking the Current and its powerful message to New England audiences. Enjoy the show!

With Northern Pass and other new transmission projects on the horizon, CLF and other leading New Hampshire environmental organizations are presenting a special free webinar on what it really means for New England to import more hydroelectric power from Canada.

The webinar will be next Friday, March 9, 2012, 2:30 to 4pm EST. Click here to register. All you’ll need is a computer and an Internet connection. Please join us, and spread the word to friends, family, and colleagues. The webinar is sponsored by CLF and our friends at the Appalachian Mountain Club, Conservation New Hampshire, The Nature Conservancy in New Hampshire, and the Society for the Protection of New Hampshire Forests (SPNHF).

The idea is to provide an accessible summary of the environmental and energy implications of imports, including the often-overlooked impacts of the new hydropower developments in Canada that will supply the power. One of the key questions is what new imports will really mean for the climate, and I’ll explain the findings of a recent report commissioned by CLF on the greenhouse gas emissions of hydropower. As we’ve often pointed out, whether and how to import more hydropower from Canada is a critical issue for the entire region’s energy future. And it’s not just about New Hampshire and Northern Pass — just last week, the developer of the Champlain Hudson project in New York announced that it is moving forward with a revised proposal for an underwater and underground transmisssion line between Canada and New York City that will have the support of state officials, municipal governments, and environmental groups.

During the webinar, you’ll hear from me, and also from Tom Irwin, CLF Vice-President and CLF-NH Director; Ken Kimball, AMC Director of Research; and Will Abbott, SPNHF Vice President for Policy and Land Management.

The webinar will feature a special guest appearance by Québecois filmmaker Nicolas Boisclair, who will be in New Hampshire this month for a series of screenings of his documentary film, Seeking the Current, which shines an unsparing light on Hydro-Québec and its ongoing $8 billion hydropower project on the Romaine River. We’ve put all the details on the screenings (and the webinar too) at this link.

At a time when both carbon emissions and fuel prices continue to rise, Vermont is poised to reduce its reliance on fossil fuels and increase the use of renewable power – a good thing at the right time.

The legislature is considering a bill that would create a renewable portfolio standard (RPS), requiring that each electric utility acquire a percentage of its electricity from renewable sources. This is an important step in the fight against greenhouse gas emissions and climate change; CLF has testified that the bill needs to be strong and ambitious.

There’s no doubt the climate needs this bill. Levels of carbon dioxide in the atmosphere continue to shoot up, and global temperatures are rising. A warming global climate has led to increased evaporation, causing droughts and floods around the world. In his testimony before the committee considering the RPS bill, climate activist Bill McKibben described the rising worldwide occurrence of extreme weather events. Among these was Tropical Storm Irene, which devastated parts of Vermont at the end of last summer. McKibben urged the committee to act now, through measures such as an RPS, before our climate crisis gets worse.

The current version of the Vermont bill would require that by 2025 all electric utilities in Vermont get 30% of their power from renewable power plants commissioned after 2012. Whatever renewable sources are already generating power now (in 2012) would not count towards the 30% standard.

Currently Vermont only has voluntary goals for utilities to acquire a certain percentage of their power from renewable sources. A fundamental flaw of the existing program is that it allows utilities to sell renewable energy credits (RECs) from Vermont renewable projects to utilities in other states, yet still count that power as renewable in Vermont. This means that the renewable attributes of the power are counted twice. The bill currently in the legislature would correct this problem.

By enacting this bill, Vermont would not be alone. Twenty-nine other states already have an RPS, including all the other New England states, and other states as disparate as Texas and Hawaii. Their requirements vary widely. Maine has an ongoing 30% RPS; New Hampshire requires 23.8% by 2025; and Rhode Island requires 16% by 2020. Details of the requirements vary, but Vermont’s proposed program compares well with other states in the region.

Vermont needs a strong renewable standard. CLF continues to push for strong measures to tackle climate change and reduce pollution.

We appreciate Northern Pass spokesman Martin Murray’s comment on my prior post regarding recent research on the greenhouse gas emissions of hydropower and the implications for the Northern Pass project. We are also grateful for Hydro-Québec environment advisor Dr. Alain Tremblay’s comment, to which I responded here.

Although we welcome the feedback and dialogue, we are discouraged that Mr. Murray’s comment addresses none of the substantive points raised by the Synapse report (PDF) or my post discussing the report. We are disappointed as well that the comment dismisses the fundamental need identified by the Synapse report – an honest and credible accounting for the effect of new imports on overall greenhouse gas emissions. Instead of working on providing such an accounting and engaging in a real dialogue about this issue, Northern Pass Transmission LLC (NPT) has invested heavily in advertising for the Northern Pass project, including the promotion of an emissions reductions figure reliant on new reservoirs that is based on an erroneous zero-emissions assumption. That assumption is contradicted by the Synapse report and Hydro-Québec’s own research, and the marketing claims on this issue (see, for example, here) are thus false and misleading and should be withdrawn immediately, as we have requested in a separate communication to NPT.

The citation to the Climate Action Plan sidesteps the merits of the emissions reduction issue entirely:

• First, the Task Force did not have the information in the Synapse report at its disposal in making its recommendations.
• Second, the Climate Action Plan contains important qualifications on its import recommendation that NPT does not acknowledge.  The recommendation itself contains the proviso that new imports should be pursued “with consideration for the broader environmental impacts of the power sources as well as the impacts that this imported power would have on the development of in‐state renewable resources.” That consideration is the work CLF believe needs to happen but has not.  In this regard, NPT’s dismissal of all questions or “challenges” on these issues is flatly inconsistent with the Climate Action Plan’s recommendation.
• Third, the Climate Action Plan appendix discussing the recommendation (PDF) states that “[t]he benefits to electric customers would be determined by the specific terms of any purchased power agreement and  the reductions to New England fossil fuel generation which would be subject to state regulatory  review and confirmation at the time of any filings for state approval.” (p. 29) In other words, the economic and environmental benefits from imports depend on the details of the proposal, specifically the terms and what generation is displaced. Yet the current proposal includes no Power Purchase Agreement that would benefit PSNH’s own energy consumers, assumes that any future power purchase agreement will be for only a small amount of power, and provides no guarantee or commitment that the imported power will reduce emissions in a meaningful way. The Synapse report directly refutes the only analysis of emissions reductions that NPT has made publicly available. The Climate Action Plan underscores the fundamental need for imports to provide real environmental and economic benefits for New Hampshire, and the current proposal on the table does virtually nothing to meet that need.
• Fourth, unlike all other recommendations in the Plan, enabling importation of Canadian hydro received a number of “no” votes from the Task Force, “due to concerns over the potential environmental impacts of the imported power and the effect imported power might have on development of in-state renewable resources.” Public comments  from a number of stakeholders, including CLF, questioned the entire recommendation based on these concerns. (Comments are summarized at pp. 246-258 of this PDF.) There was a debate then, and that debate should continue now, based on well-sourced and credible information like the Synapse report.

We agree that there is no one single solution to the climate challenge. But any serious effort to confront climate change in New Hampshire must also confront the largest source of greenhouse gas emissions in the state – PSNH’s aging, inefficient, and uneconomic fossil fuel power plants. As Dr. Tremblay of Hydro-Québec admitted, in comments that NPT is now approvingly citing, “the major environmental challenge facing North America is to replace coal to generate power….” CLF couldn’t agree more.

It seems NPT and its affiliates do not agree with Dr. Tremblay. Importing an additional 1,200 megawatts of hydropower from Canada will not help move New England toward a clean energy future if, as the current proposal is structured and as PSNH has repeatedly claimed, imports would only displace relatively clean natural gas generation, and not the power plants that are worst for the climate, like PSNH’s coal-fired units at Merrimack and Schiller Stations.

With Northern Pass proponent PSNH fighting tooth and nail to protect its guaranteed ratepayer subsidy to keep running those units, the supposed commitment of Northern Pass’s developers to reducing greenhouse gas emissions appears to be a textbook example of a greenwash. Given the emissions data presented in the Synapse report, it is clear to CLF that, if Northern Pass proceeds as proposed, our region will forfeit a major opportunity for meaningful action to confront climate change.

Steven Syre, in his widely read Business news column in the Boston Globe, delves into one of the many important aspects of the settlement between the Commonwealth of Massachusetts and Northeast Utilities and NStar, setting the stage for those two utilities to proceed with their plans to merge. As he notes, most of the attention (understandably) about that settlement has been focused on the provision regarding the purchase of power, by NStar on behalf of its customers, from the Cape Wind project.

However, Syre discusses the provisions of the settlement regarding imports of power from large hydroelectric facilities in Quebec into New England. He notes that the settlement includes a commitment by the Massachusetts utilities signing the agreement that they would not use any large hydropower to meet state-mandated renewable energy targets for the next five years and describes the concerns that lead to this conclusion.

Syre describes how, “State officials and others point to several reasons why it would be a bad idea to count hydropower as a source of power that qualifies as renewable energy. They say that such a designation could increase the price of hydropower and hinder the long-term development of other forms of renewable energy.”

He notes that:

“Other critics even think Hydro-Quebec’s environmental benefits are being oversold. A new study commissioned by the Conservation Law Foundation says large-scale Canadian hydropower will produce ‘substantial greenhouse gas emissions that are comparable to those of modern natural gas-fired power plants.’”

CLF’s take on the agreement grows out of our deep involvement in the merger proceeding and our engagement with many issues that are addressed in the settlement. These include both the Cape Wind project and the questions about the net environmental impact of large hydroelectric power. CLF commissioned the study that Syre discusses, as well as a related analysis that highlights the existential threat to New England-based renewable power from designating large hydropower as eligible for financial incentives under our renewable energy laws.

All of the provisions of the agreement work together to move towards the goal of net gain for the customers of the merging companies and movement towards attaining the important environmental goals of Massachusetts. As Sue Reid of CLF, our lead advocate on the merger, said about the settlement, it is a significant advancement for Massachusetts and all of New England in a number of regards:

• It removes the last major hurdle to building Cape Wind;
• It ensures that the Commonwealth will continue to reap the cost savings and environmental benefits of the Massachusetts Green Communities Act;
• It will help ensure that imported hydropower does not diminish other renewable energy deployment in Massachusetts and beyond;
• It will reduce barriers to installation and operation of small, distributed renewable energy generating facilities in Massachusetts; and
• It will freeze the merged utility’s rates for 4 years, will require transparent public review of NSTAR’s electric and gas rates before the rate freeze expires, and will deliver – upon approval of the merger – an immediate 50% credit to Massachusetts customers based on expected merger savings during the first 4 years following merger approval.

All of these provisions are significant and are reason to hail this agreement as an important landmark in the evolution of our energy system and the march towards a cleaner and better future where our economy, environment and communities can all thrive.

Today, the Patrick Administration reached a breakthrough settlement agreement in the proposed merger between NStar and Northeast Utilities, which, if approved, will create one of the country’s largest public utilities. The agreement is a big win for renewable energy, as it positions Massachusetts to finally unleash the power of Cape Wind, our region’s most promising new clean energy source, and to lead the rest of the country forward on offshore wind.

The settlement ensures that this powerful new utility will be in lockstep with Massachusetts’ nation-leading clean energy policies and propel the state forward instead of backwards in implementing them.

This is a significant advancement for Massachusetts and all of New England in a number of regards:

• It removes the last major hurdle to building Cape Wind;
• It ensures that the Commonwealth will continue to reap the cost savings and environmental benefits of the Massachusetts Green Communities Act;
• It will help ensure that imported hydropower does not diminish other renewable energy deployment in Massachusetts and beyond;
• It will reduce barriers to installation and operation of small, distributed renewable energy generating facilities in Massachusetts; and
• It will freeze the merged utility’s rates for 4 years, will require transparent public review of NSTAR’s electric and gas rates before the rate freeze expires, and will deliver – upon approval of the merger – an immediate 50% credit to Massachusetts customers based on expected merger savings during the first 4 years following merger approval

We applaud the Administration for recognizing that a lot of ground needed to be made up in order for this merger to benefit the public and for covering that ground with thoughtful terms that benefit ratepayers and the environment both in the short and the long-term.

Hydro-Québec hydroelectric projects recently commissioned or under construction (Source: Quebec Ministry of Natural Resources and Wildlife)

Reducing the region’s emissions of greenhouse gases is supposedly the Northern Pass project’s marquee public benefit, its raison d’être as they say in Québec. But would the Northern Pass project do the job?

The answer appears to be: probably not any time soon. Today, CLF is releasing a ground-breaking new technical report regarding the greenhouse gas emissions of Canadian hydropower. The conclusions of the report show that large-scale hydropower, especially new reservoirs, is worse for the climate than Northern Pass’s developers are claiming, with substantial greenhouse gas emissions that are comparable to those of modern natural gas-fired power plants. The current Northern Pass proposal substitutes hydropower for natural gas in New England’s energy mix, meaning that the project won’t reduce emissions by much if any, especially in the near term.

Authored by Synapse Energy Economics, the technical report released today, Hydropower Greenhouse Gas Emissions: State of the Research, is an independent survey of the recent science regarding the greenhouse gas emissions of hydropower. The science is clear that the reservoirs behind hydropower dams emit greenhouse gases, relative to the forests and wetlands they flood (which often take greenhouse gases out of the atmosphere). Overall, reservoirs in Québec emit more greenhouse gases over the course of their lives than renewables like wind, solar, and run of river hydropower.

A crucial finding of the report concerns new reservoirs. In the first several years after a reservoir is dammed, large amounts of newly inundated organic material decompose, emitting carbon dioxide that diffuses through the water into the atmosphere. As a result, a reservoir’s net emissions in its early years are very high – starting out even higher than emissions from a natural gas power plant per unit of power generated. This effect is evident in recent, rigorous analyses by several teams of scientists, based on data collected at Hydro-Québec’s Eastmain 1 reservoir in northern Québec. This reservoir is the very same project that Northeast Utilities’ CFO testified under oath last year would be the primary, if not exclusive, source of Northern Pass’s power. Even when their emissions are projected over their lifetimes, newly flooded Canadian reservoirs may emit nearly two-thirds of the greenhouse gases emitted by natural gas power plants. By contrast, reservoirs emit only about 20% of the greenhouse gases emitted by typical coal-fired power plants.

This conclusion is the death knell for Northern Pass Transmission, LLC’s (NPT) claim that the current Northern Pass proposal would reduce greenhouse gas emissions by up to 5 million tons. We explained the claim’s key flaw – the report on which it is based erroneously assumes that hydropower has no greenhouse gas emissions – back in August. In light of today’s report, CLF is calling on NPT and its partners NU, NSTAR, and PSNH to stop citing that erroneous number and to withdraw all marketing materials for the Northern Pass project that state or imply that Canadian hydropower has no or minimal greenhouse gas emissions. Hydro-Québec is building new hydropower projects that are intended to facilitate new exports to the northeastern United States. To the extent that the prospect of exports is driving the construction of new reservoirs, Northern Pass and projects like it will be responsible for those reservoirs’ emissions and also their other adverse environmental impacts. And if, as the developers’ analysis concluded, the power to be displaced by imports through Northern Pass is overwhelmingly from natural gas plants, the emissions from a succession of new reservoirs in Canada may replace – perhaps completely for a period of time – the emissions of displaced natural gas power. In that scenario, the Northern Pass project would do little – or even nothing – to reduce greenhouse gas emissions, at least in the near-term.

The report makes another critical point about a different kind of displacement that could occur with Northern Pass. According to a recent study, stepping up Hydro-Québec’s exports to the United States may actually decrease its exports to other provinces in Canada, where the need for fossil fuel-fired power then increases, resulting in additional emissions. Those emissions may cancel out any reductions from displaced power in the United States. This effect is a potential blind spot that needs to be considered and analyzed as part of the public review of any new imports.

The report’s findings are important information regarding the environmental impacts of the project that the U.S. Department of Energy must consider as part of its review of Northern Pass’s application for a Presidential Permit. For that reason, earlier today, CLF submitted the report to DOE along with Synapse’s analysis of the potential effect of Northern Pass on the regional market for renewable energy.

To CLF, the report suggests that new imports could be part of the region’s climate strategy if imports:

• displace dirty power, like project sponsor PSNH’s uneconomic, subsidized power plants, to achieve a meaningful net reduction in greenhouse gas emissions without increasing the use of fossil fuel-fired power plants in Canada;
• support – rather than undermine – local renewable projects and energy efficiency efforts in New England; and
• have minimal impacts on the environment and communities on both sides of the border.

PSNH is in a unique position to take its coal units offline, in conjunction with its potential power purchase agreement with Hydro-Québec that is supposedly in the works. Instead, PSNH is marching on with its broken coal-based business model at great cost to New Hampshire consumers and the environment. Unless the proposal changes, the Northern Pass project does not deliver on the developers’ claims and will not advance a cleaner energy future for New England.

When shopping for a new car, it helps to know its fuel economy and how that stacks up with other models. What if you could have the same information when buying a new home? The Vermont Legislature is currently considering two bills, H-497 & S-143, which require sellers of buildings to provide information about a building’s efficiency. Sellers calculate a building’s efficiency using a free online tool approved by the Department of Public Service (Department). Buyers can then know a building’s energy rating. The rating is presented as a single number that compares that building with other similar buildings. In addition, a buyer could access other information such as the building’s total energy consumption, its square footage, energy intensity and annual energy costs.

This bill continues Vermont’s tradition of leading the nation in setting effective energy efficiency policies. It lets buyers know important energy use information before they make a big investment. The additional step of helping more customers improve their building’s heating efficiency is still needed. Vermont’s cold winters and old building stock makes bolstering buildings’ thermal efficiency low-hanging fruit.

While Vermont leads the way on electric efficiency, it still has a ways to go on improving heating efficiency. In 2012, Efficiency Vermont (EVT), Vermont’s efficiency utility, used 81% of its budget for electric efficiency resources and only 8% for heating efficiency. The divergence can be traced in part to funding sources. Electrical efficiency investments are funded from a savings charge on electric bills. Heating programs currently have limited funding available and rely mostly on proceeds from the Regional Greenhouse Gas Initiative (RGGI) and participation in the regional grid’s capacity market. To bolster heating efficiency programs, S-143 directs the Department to study additional mechanisms for funding these programs. Vermont’s 2011 Comprehensive Energy Plan has recognized the need for new funding sources for weatherization improvements in light of the fact that current policies will leave the State far short of reaching its goal of weatherizing 80,000 homes by 2020.

In Massachusetts, a system similar to the funding model for electric efficiency is being considered.  H.3897 would establish a comprehensive thermal efficiency program funded by a 2.5 cents per gallon savings charge on heating oil. Funds will be used to provide incentives for upgrading older inefficient oil heating systems, weatherizing, and helping low-income communities heat their homes in winter. Since 59% of Vermonters heat with oil, and savings programs are already available for gas users – which has limited availability in Vermont – it only makes sense for Vermont to expand the savings available for customers who rely on oil.

While some opposition from fuel dealers exists, given that heating oil prices are at an all-time high, there is a good opportunity now for fuel dealers to partner with customers to keep their houses warm, save energy, reduce pollution and grow jobs.  Information about a building’s energy use is a good first step, but Vermonters need more to keep more warmth inside and more money in their pockets.
