Last year I wrote about the two major energy revolutions happening globally, the shale revolution--mainly in the US--and the renewable energy revolution, focused more on technologies than geography but with big concentrations in Europe and increasingly Asia and the Americas. Two stories in the Financial Times (registration/subscription required), which has lately been doing an excellent job covering energy, illustrate that we are still in the early days of both. Bigger changes lie ahead.
One story covers the development of the "South Central Oklahoma Oil Play", or SCOOP, an acronym that's new to me and, I suspect, many of my readers. Continental Oil, a major player in the Bakken and other shale oil resource areas, has apparently reported that SCOOP may contain up to 3.6 billion barrels (oil equivalent) of recoverable oil and gas. That's more oil than was produced in Alaska in the last 15 years, based on the graphic accompanying the article.
Along with the unconventional portions of the Permian Basin in Texas and New Mexico and Ohio's Utica shale, and with the reviving liquids production from Wyoming's Powder River Basin and elsewhere, the upside for US oil output still looks significant. Its economics may become challenging if oil prices remain weak for more than the next year or two, but our picture of oil and gas as mature resources may need to be revised.
The title of the other article, "US Solar and Wind Start to Outshine Gas" seized my attention. Its key quote is from the head of power, energy & infrastructure at investment bank Lazard: "We used to say some day solar and wind power would be competitive with conventional generation. Well, now it is some day"--at least for some technologies, in some locations, at larger scales. The firm's latest analysis shows continued cost declines for wind and solar.
It also raises a very interesting and pertinent question about whether subsidies for residential-scale solar (i.e., rooftop PV, which remains much costlier than at utility scale) are "distorting the long-term energy planning process." That's a question we are likely to hear a lot more about when the current US 30% investment tax credit for solar equipment, which benefits higher-cost installations more than cheap ones, comes up for renewal. Nevertheless, solar power, particularly in combination with emerging energy storage solutions, looks increasingly likely to transform the utility landscape in the years ahead.
You may have noticed a decrease in my blogging frequency, recently. I've been preoccupied with project work and personal matters for the last couple months, but I should be back to my normal pace by October. There's certainly no shortage of topics worth discussing here.

IEA Forecasts Sustained Energy Growth, But No "Era of Oil Abundance"
- The IEA's latest long-term forecasts highlights the growth of unconventional oil and gas, especially in North America, but does not see this leading to much lower oil prices.
- In their main scenario fossil fuels will still meet more than three-fourths of the world's energy needs by 2035, despite significant growth in renewable energy.
As in previous years, the new WEO examines the full range of energy supply and demand, with a focus this time on the sources and uses of petroleum, and the emergence of Brazil as an oil and energy power. While recognizing that they might be underestimating the potential for technology or additional resource discoveries to sustain the growth of "light tight oil", or shale oil, which together with oil sands and gas liquids is a primary driver of oil supply growth today, the IEA forecasts it would peak by 2025.
That puts the burden for supporting oil demand growth and the replacement of supplies lost to natural decline after 2025 back onto the Middle East producers. So in the IEA's view, OPEC's loss of market power appears temporary. A corollary to this is that the agency does not anticipate a sustained drop in oil prices, but rather a gradual increase of about 16% by 2035. That's because the unconventional oil helping to drive current market shifts is still relatively high-cost, compared to the large conventional oil resources of the Middle East.
Although the IEA expects the global oil market to grow from its present level of around 90 million barrels per day (MBD) to 101 MBD in 2035, that change would be less than their forecasted equivalent global growth in gas, renewables or even coal. The concentration of oil demand in transport and petrochemicals would also increase, while other uses contract slightly. This is consistent with last year's observation that the center of the oil market is shifting towards Asia, since around one-third of the total anticipated growth in oil demand is for diesel to fuel goods deliveries in Asia.
The shift toward Asia applies to other forms of energy, as well, including natural gas and the expanded use of renewable energy. This trend is already altering global energy trading patterns, and with the US becoming more energy self-sufficient the IEA sees a new role for energy exports from Canada to supply Asia. That includes both LNG and oil sands, which Fatih Birol, the IEA's chief economist, recently indicated the agency sees as only a minor, incremental threat to the climate compared to growing coal use.
An added nuance in this year's outlook is that the IEA now expects world-leading energy growth in China to be overtaken in a decade or so by faster growth in India, while rapidly growing consumption in the Middle East could result in that region posting the second-highest growth in primary energy demand through 2035, especially for natural gas.
In the launch presentation in London Dr. Birol assessed the consequences of strong North American energy growth and shifting exports and imports for the prices that industries pay for energy. Because any exports of low-cost North American shale gas must be priced to cover the cost of liquefaction and long-haul freight, plus a margin, global natural gas prices should converge somewhat but still not equalize among the major consuming regions. As a result, the IEA expects US-based energy-intensive industries to have a persistent cost advantage in both gas and electricity, enabling them to increase their share of global markets. That has implications for employment and economic growth, while sustained energy price disparities should also drive energy efficiency improvements in response.
Another issue that received prominent attention at the launch was the always controversial matter of subsidies, for both conventional and renewable energy. The IEA estimated global fossil fuel subsidies at $544 billion 2012--mainly in developing countries and Middle East oil producers--resulting in "wasteful consumption" and fewer benefits for the poor than commonly claimed. And while supporting the use of subsidies to promote greater use of renewable energy, the agency's Executive Director, Maria van der Hoeven, made a particular point about the necessity for such subsidies to be carefully targeted and very responsive to changes in technology cost.
The IEA was founded in the aftermath of the 1973-74 Arab Oil Embargo and will celebrate its 40th anniversary next year. I couldn't help thinking about that as I reviewed the updated WTO materials. They're interesting as an annual update, but also in reflecting how the world of energy has changed since the oil shocks of the 1970s.
The rapid development of unconventional oil and gas that underpins the IEA's latest forecast would likely have amazed the industry veterans I met at the start of my career, but still fit within their worldview. I think they would have found the projected growth of renewable energy, supported by climate-change-inspired subsidies that surpassed $100 billion per year in 2012 more futuristic and surprising. Yet despite the anticipated expansion of renewable energy sources over the next 22 years, the IEA envisions the share of fossil fuels in the world's total energy supply only falling from 82% today to 76% in its main "New Policies" scenario. That will seem overly cautious to many, but it underlines the challenges involved in changing such massive systems.
I'd like to wish my readers all the joys of the holiday season and a happy and prosperous New Year.

Could US Oil Trends Alter How Oil Prices Are Set?
- Oil prices weren't always set by a transparent global market. Current pricing mechanisms emerged from much less transparent precursors.
- Resurgent US production, combined with restrictions on US oil exports, could disconnect the US from the global oil market, with unexpected results.
The market-based system of oil prices, with its transparency and easy trading among regions, didn't appear overnight. Until the early 1970s, Texas played a role similar to Saudi Arabia's current swing producer role within OPEC. By limiting the output of the state's oil wells, the Texas Railroad Commission effectively determined the global price of oil--to the extent there was one--until Texas had no spare capacity left. That set the stage for OPEC, a succession of oil crises, and the US oil price controls that were imposed in the 1970s in an attempt to help manage inflation. There was also no single, representative oil price. Instead, prices were set by producers' contract terms and the discounts large refiners could negotiate, or by federal regulations. The current system emerged from a series of developments in the 1980s.
When US oil price controls ended in 1981, oil futures trading was just getting underway on the New York Mercantile Exchange. The heating oil contract was launched in 1980, followed by the West Texas Intermediate (WTI) crude oil contract in 1983. This combined large-scale oil trading with an unprecedented level of transparency. It was also significant that the US, the world's biggest oil consumer, had become a major oil importer after domestic production peaked in 1970. Because refineries on the coasts competed for oil supplies with refiners on other continents, the price of WTI couldn't get too far out of line with imported crudes without creating arbitrage opportunities for traders. And any part of the US connected by pipeline to the Gulf Coast was effectively linked to oil prices in Europe, the Middle East and Asia.
After OPEC miscalculated the response to the very high prices its members were demanding in that period--reaching $100 per barrel in today's dollars--global oil demand shrank by nearly 10% from 1979 to 1983, while non-OPEC production grew by more than 12%. Prices soon collapsed, and OPEC's dominance of oil markets faded for most of the next two decades, during which the futures exchanges and trading relationships of the modern oil market took hold.
What could shake the current system of oil prices? It has already withstood recessions, wars in the Middle East, the collapse of the Soviet Union, and the explosive growth of Asia, with China alone adding oil demand comparable to that of the EU's five largest economies. However, since the current system is based on the free flow of oil between regions, anything that impedes that flow could undermine the way oil is currently priced.
Setting aside conflict scenarios, consider the potential impact of sustained growth in US production, combined with flat or declining demand and no change in the current prohibition on most US crude oil exports. The gyrating differential between WTI and UK Brent crude, reflecting rising production in the mid-continent and serious logistical bottlenecks, provides a glimpse of what this could be like. With much of the new US production coming in the form of oils lighter than those for which most Gulf Coast refineries have been optimized, keeping rising US crude output bottled up here could result in US crude prices diverging even farther from global prices, while forcing US refineries to operate less efficiently and import and export more refined products. With oil imports drastically reduced and oil exports still banned, US oil prices might be influenced more by the global market for refined products, with its different dynamics and players, than by the global crude oil market .
In some respects, that sounds a lot like what many politicians and "energy hawks" have been seeking for years: a US no longer subject to foreign oil producers' price demands. Yet this same scenario could yield all sorts of unintended consequences, including a less competitive US refining industry and higher or at least more volatile prices for gasoline, diesel and jet fuel. And just as we've seen with cheap natural gas, cheaper oil could undermine the economics of the unconventional oil and gas production that makes it possible in the first place.
US oil export policy merits a thorough reevaluation, and soon, because the regional impacts of a continued no-export stance could become pronounced, even if the US never reached overall oil self-sufficiency. Such a review should include related regulations, such as the Jones Act restrictions on shipping. With crude oil exports to Canada -- virtually the only allowed export destination for our newly abundant crude types--already rising rapidly, some Canadian refineries may be positioned to supply US east coast fuel markets more cheaply than refineries in New Jersey. That certainly qualifies as an unintended consequence.

Should Alaska Export More LNG to Asia?
The Governor of Alaska reportedly met
this week with officials from the South Korean national gas company to
discuss exports of liquefied natural gas (LNG). Ever since crude oil production on Alaska's North Slope ramped
up in the 1980s, industry observers have speculated about the ultimate
disposition of the significant associated natural gas reserves found with the
oil. In a letter filed with the state of Alaska, BP, ConocoPhillips and ExxonMobil, the three main North Slope
producers, together with pipeline company Transcanada, recently confirmed their
plans for a potential liquefied natural gas (LNG) project, instead of the
long-mooted pipeline to deliver the gas to America's lower-48 states. The
contemplated megaproject would validate both the scale of Asia's future LNG
market and the long-term nature of the US shale gas revolution.
Alaska's North Slope has already yielded 15 billion barrels of oil. Production peaked at over 2 million barrels per day in 1988 and subsequently declined to less than 600,000 barrels per day last year. With around 6 billion barrels of remaining reserves, it's still a very significant field but well past its prime. While the public has focused on its oil output, the producers and the state have long had their eyes on how best to harvest the value of the 35 trillion cubic feet (TCF) of gas dissolved in the oil. In fact, the North Slope complex has produced several TCF per year of gas for years, ranking it among the largest gas fields in the world, but almost all of that gas has been reinjected into the formation to aid oil recovery--and for lack of a market in an isolated and sparsely-populated state.
For decades the default assumption was that a pipeline would eventually be built across Alaska and Canada to link this gas to the existing network feeding the contiguous US. That idea gained traction when US marketed gas production stalled around 2000 and then began to decline. The economics of an Alaskan gas pipeline compared poorly with gas produced along the Gulf Coast, but competing with rising LNG imports looked much more feasible. Then along came unconventional gas, starting with coal-bed methane and culminating with the surge of shale production since 2005. The US gas market now has enough domestic supply to shrink coal's contribution to US power generation by 7% since 2008 and revive gas-intensive industries.
If shale gas were only a short-term phenomenon, as some have suggested, it would be of little relevance to the plans of the North Slope producers. All they'd need to do would be to delay their pipeline for a few more years, and the market would come to them. However, estimates put US shale gas resources at between 482 and 686 TCF--a 60-90 year supply at current shale production rates. And the fact that all three of the main North Slope producers have invested in significant acreage positions and production in US shale basins surely gives them insights into the longevity of those resources.
Nor is time on the side of the Alaskan producers. As oil production declines the economics of the North Slope operation will deteriorate, while keeping the Trans Alaska Pipeline full becomes more problematic. Finding an attractive outlet for the North Slope "gas cap" wouldn't just provide a new revenue source; it could keep oil production going for additional decades.
The LNG option offers several advantages, despite its estimated $45-65 billion price tag and technical complexity. For starters, it cuts roughly 1,000 miles of difficult terrain off the distance that the gas must be pipelined, in this case to a site on the southern Alaskan coast. That location is much closer to Asia, the world's largest LNG market, than export projects intended to ship LNG from the US Gulf Coast. The Asian market is also growing, thanks in part to Japan's post-Fukushima reassessment of nuclear power. The Japanese government has backed away, at least for now, from plans for a firm nuclear phase-out, but it seeks to diversify its energy sources. Among other steps taken in the aftermath of the Sendai quake and nuclear disaster, it has instituted the world's most attractive solar power incentives. Yet Japan's solar resources provide just a few hours of peak output per day, on average, requiring substantial fossil fuel generation to fill in the gaps. Power plants burning LNG are well-suited to that task.
China presents a more complex picture, with its own significant shale gas potential and an energy market expected to add as much natural gas demand by 2035 as all the world's developed countries put together. Considering the scale of eventual demand and the infrastructure necessary to bring China's shale gas to market, it seems likely that the growth of the market in the interim must depend heavily on LNG imports.
Assuming that the state of Alaska presents no obstacles and that US export permits would be forthcoming, because Alaskan LNG exports wouldn't impact US natural gas prices, the main questions that will determine the future of this project can't be answered definitively today. Among these are whether the numerous competing LNG projects being planned and built around the Pacific Rim and elsewhere will saturate the global market in the meantime, and whether the market will provide an attractive price for Alaskan LNG, influenced more by crude oil prices than by US shale gas. The North Slope producers are already immersed in these issues via their other activities, including ConocoPhillips' small LNG plant in Kenai, Alaska, which has been shipping LNG to Asia for more than 40 years. The project timeline provided to the state includes at least three go/no-go decisions along the way as the answers to these questions unfold.

IEA Expects Global Energy Focus to Shift Eastward
Last month the International Energy Agency (IEA) released its annual long-term forecast, the World Energy Outlook (WEO). Its projection that US oil output would exceed that of Saudi Arabia within five years was featured in numerous headlines, although some of the report's other findings look equally consequential. That includes the continued strong growth of energy demand in China, India and other Asian countries, and the linkages between that growth and a dramatic expansion of Iraqi oil production. The agency also set a cautionary tone concerning the increase in global greenhouse gas emissions accompanying all this growth.
In the IEA's primary "New Policies" scenario, the US overtakes Saudi Arabia in oil production by 2017, adding 4 million barrels per day (MBD) of unconventional output, mainly from shale (tight oil) deposits such as the Bakken in North Dakota. US oil imports decline significantly, due in roughly equal measure to higher production and the implementation of strict vehicle fuel economy regulations. As a consequence, the need for imports from the Middle East approaches zero within 10 years. When this change is combined with the growth in oil demand in Asia, where China alone accounts for half the forecasted global growth in oil consumption in this period, the IEA envisions Asia becoming the recipient of 90% of Middle East oil exports by 2035.
The detailed assumptions behind the IEA's conclusions weren't provided in the public release. These include crucial questions such as the assumed status of US rules barring most crude oil exports. As noted in a Reuters op-ed at the time, maximizing the potential of US unconventional resources may depend on allowing higher quality unconventional oil to seek global markets, while continuing to import oil from Latin America and the Middle East into Gulf Coast refineries geared to these heavier, higher-sulfur feedstocks. The op-ed's author also reminded us that the natural gas liquids included in the headline comparison with Saudi production are useful but quite different from crude oil, yielding little gasoline and diesel fuel.
The expected growth of energy demand in China remains extraordinary, even with the country's economic growth slowing from the levels seen a few years ago. To put this in context, when Dr. Fatih Birol, Chief Economist of the IEA, presented the new WEO to the media in London on November 12th, he suggested that China's electricity demand would grow by the equivalent of "one US and one Japan of today" by 2035. Much of that additional electricity generation is projected to come from renewables, nuclear power and domestic gas. Nevertheless, and in spite of significant increases in China's unconventional gas production, the IEA forecasts that import dependence will grow from about 15% for gas and 50% for oil today, to 40% for gas and over 80% for oil by 2035. That increase in imports would equate to additional hundreds of millions of dollars per year of outflows for energy.
In the view of the IEA, much of the extra oil demanded in Asia will be supplied by Iraq, which they project will increase its output from around 3 MBD today to 6.1 MBD in 2020 and 8.3 MBD in 2035, in the process becoming the world's second-largest oil exporter, after Russia. Since the reserves to support that growth have already been identified, with much lower production costs than many other basins, the uncertainties involved are mainly political and structural. Resolution of the current standoff with Iran over its nuclear program would provide even more Middle East oil for Asian markets.
As in its earlier "Golden Age of Gas" scenario, the IEA expects large increases in global natural gas consumption. Unconventional sources, mainly in the US, China and Australia, would contribute around half the additional production required to meet expanded demand. However, at the launch presentation in London Dr. Birol also stressed that unconventional oil and gas are still at an early stage, with significant uncertainties about the eventual magnitude of their resources. This seemed to be a particular issue for the agency's post-2020 forecast of oil production in the US and gas production in China.
Despite the rigorous analysis and level of detail involved in producing the IEA's World Energy Outlook, long-term energy forecasting should always be taken with a grain of salt. Yet whether or not the highlighted trends mature precisely in line with these projections, the shifts that the IEA identified are significant and already becoming evident in current data for energy production, consumption and trade. Even if North America failed to become a net oil exporter--which many equate with energy independence--by 2030, the movement of the center of gravity of global energy trade towards Asia is essentially pre-determined: baked in by differences in economic growth rates and resource opportunities. The economic, geopolitical and environmental consequences of that shift are just starting to take shape.

The Golden Age of Natural Gas
A regular reader of this blog kindly sent me a link to the International Energy Agency's new study on global natural gas, to which he contributed. The report, entitled, "Are We Entering A Golden Age for Gas?" was launched with a press conference yesterday in London. It presents a scenario in which gas use grows rapidly due to faster demand growth, particularly in the developing world, increased supply from unconventional sources such as shale gas, and a slower expansion of nuclear power in the aftermath of the Fukushima Daichi accident. Its key findings envision gas providing 25% of world energy by 2035, up from 21% today, and eclipsing the share of coal before 2030, with corresponding benefits for global greenhouse gas emissions.
The IEA's presenters were careful to point out that they are not proposing this view as the likeliest scenario, but as an offshoot of their primary World Energy Outlook scenario published last fall, which incorporated the commitments at the Copenhagen climate conference. The new gas scenario depends on a number of uncertainties, including the resolution of some of the concerns about the environmental impacts of unconventional gas production, along with the realization of carbon-intensity and gas-development targets in places like China. However, it doesn't depend on new technology or dramatic changes such as a massive move to natural gas for vehicle use. (The latter is presented as a "High Impact Low Probability" sensitivity.) Its big shifts occur in the big existing gas market segments, for power generation globally and for industry and buildings in the developing world.
I was struck by several elements of the scenario. First, although much of the focus on unconventional gas has been on North America, where many of the techniques were pioneered, this is very much a global story. The IEA shows estimated unconventional gas resources from shale, "tight gas" and coal-bed methane that exceed conventional gas resources in Asia and Africa and rival them even in Eastern Europe/Eurasia. On the strength of its unconventional resources China could become the world's third-largest gas producer by 2035, behind Russia and the US. So even if the US plaintiffs bar attempts to turn "fracking" into the next tobacco or asbestos, unconventional gas exploitation will likely progress elsewhere. At the same time, increases in conventional gas production are expected to exceed those from unconventional sources, by 60/40 over the period studied. That requires big increases in LNG production in Australia and a substantial increase in pipeline capacity linking Russian and Central Asian gas to markets in Europe and Asia. It's also worth noting that despite the shale gas bonanza, the IEA doesn't envision the US becoming a net gas exporter.
As one of my mentors frequently reminded me, natural gas doesn't get developed without a market, and in this scenario the biggest source of new demand is in power generation, where the combination of lower gas prices and the 60% thermal efficiency of combined cycle gas turbines makes gas highly competitive, even with coal. It's less clear whether gas is taking market share from new nuclear based on price, or mainly filling the gap that the response to Fukushima is leaving in some markets. From what I heard on a power industry webinar yesterday, the former is a significant factor, at least in the US. The strong connection between gas and power is another reason why so much of the growth in gas demand--80% by the IEA's estimate--is expected to occur in developing countries including China and India, where electricity demand is expanding at rates that the US and Europe haven't experienced for years or decades. Perhaps the most startling forecast in the report is that China's gas demand could grow from roughly matching Germany's today to about the level of the entire EU in 25 years. That would be supported as much by additional imports as from domestic unconventional gas output.
As I'd have expected, the IEA provided a sober assessment of the environmental implications of their scenario. Increasing the share of gas in global energy demand reduces global GHG emissions by 160 million tons of CO2 equivalent by 2035--less than 1% of total emissions--by substituting for coal and some oil. That's a lot less than if the extra gas didn't also contribute to higher energy demand by keeping electricity prices lower, while outcompeting some lower-emission renewables and nuclear projects. The IEA states plainly that relying on more gas is not a silver bullet for climate change, although it is a positive step.
In addition to pointing out the need for safe handling of the fluids involved in hydraulic fracturing, the report also specifically addresses the critique of Howarth and others concerning the direct emissions from shale gas production. The IEA found that CO2-equivalent emissions for shale gas from well to burner exceed those for conventional gas by 3.5%-12%, depending on whether the methane liberated during well completion is captured, flared or vented to the atmosphere. Even at the high end, that does not negate gas's emissions advantage over other fossil fuels, especially when power generation efficiencies are factored in. The report's authors apparently see most of the excess emissions compared to conventional gas production as representing an opportunity that can be captured with current technology and best practices.
The IEA put a price tag on this shift to gas: a cumulative $8 trillion through 2035 , nearly $1 trillion higher than the gas infrastructure investment in their global energy scenario of last fall. Those figures aren't as hard to fathom in the context of developed-country budget deficits and debt as they might seem, because they mainly reflect unsubsidized, economically attractive investments by publicly-traded and state-owned energy companies that are making healthy profits and have substantial cash flow on which to draw. Surprisingly, the IEA sees most of the incremental investment in gas coming at the expense of oil. Although they deliberately framed the title of their scenario as a question that hinges on a number of variables, the report comes across as a plausible and credible glimpse of our possible energy future.
The IEA's presenters were careful to point out that they are not proposing this view as the likeliest scenario, but as an offshoot of their primary World Energy Outlook scenario published last fall, which incorporated the commitments at the Copenhagen climate conference. The new gas scenario depends on a number of uncertainties, including the resolution of some of the concerns about the environmental impacts of unconventional gas production, along with the realization of carbon-intensity and gas-development targets in places like China. However, it doesn't depend on new technology or dramatic changes such as a massive move to natural gas for vehicle use. (The latter is presented as a "High Impact Low Probability" sensitivity.) Its big shifts occur in the big existing gas market segments, for power generation globally and for industry and buildings in the developing world.
I was struck by several elements of the scenario. First, although much of the focus on unconventional gas has been on North America, where many of the techniques were pioneered, this is very much a global story. The IEA shows estimated unconventional gas resources from shale, "tight gas" and coal-bed methane that exceed conventional gas resources in Asia and Africa and rival them even in Eastern Europe/Eurasia. On the strength of its unconventional resources China could become the world's third-largest gas producer by 2035, behind Russia and the US. So even if the US plaintiffs bar attempts to turn "fracking" into the next tobacco or asbestos, unconventional gas exploitation will likely progress elsewhere. At the same time, increases in conventional gas production are expected to exceed those from unconventional sources, by 60/40 over the period studied. That requires big increases in LNG production in Australia and a substantial increase in pipeline capacity linking Russian and Central Asian gas to markets in Europe and Asia. It's also worth noting that despite the shale gas bonanza, the IEA doesn't envision the US becoming a net gas exporter.
As one of my mentors frequently reminded me, natural gas doesn't get developed without a market, and in this scenario the biggest source of new demand is in power generation, where the combination of lower gas prices and the 60% thermal efficiency of combined cycle gas turbines makes gas highly competitive, even with coal. It's less clear whether gas is taking market share from new nuclear based on price, or mainly filling the gap that the response to Fukushima is leaving in some markets. From what I heard on a power industry webinar yesterday, the former is a significant factor, at least in the US. The strong connection between gas and power is another reason why so much of the growth in gas demand--80% by the IEA's estimate--is expected to occur in developing countries including China and India, where electricity demand is expanding at rates that the US and Europe haven't experienced for years or decades.
