UK Energy Minister Ed Miliaband

By Richard Littlejohn with apologies to Bob Dylan 😉

“How many pits must a man close down

Before we run out of coke?

How many North Sea oil rigs must shut

Before the UK goes broke?

Yes, and how many windmills must the countryside take

Before it’s beyond a sick joke?

Disaster, my friend, is blowin’ in the wind

Disaster is blowin’ in the wind.

Yes, and how many more must be dumped on the dole

Before the worm starts to turn?

Yes, and how long will we go on importing foreign coal

As if we’ve got money to burn?

Yes, and how many times will the lights go out again

Before this madman will learn?

Disaster, my friend, is blowin’ in the wind

Disaster is blowin’ in the wind.

Yes, and how much higher will our gas bills have to go

So Miliband can play superhero?

Yes, and while the economy goes up in flames

Mister Ed fiddles madly like Nero,

Yes, and how many old folk will die from the cold

In futile pursuit of Net Zero?

Disaster, my friend, is blowin’ in the wind

Disaster is blowin’ in the wind.

And here is Miliband with his version (You can’t make this up! 😉):

38 House members call for repeal of IRA subsidies

Posted in CCS, climate, energy policy, Uncategorized, tagged , , on May 1, 2025| Leave a Comment »

“Despite our previously unified stance, some Members of our conference now feel compelled to defend wind and biofuel credits, advocate for carbon capture and hydrogen subsidies, or protect solar and electric vehicle giveaways. Keeping even one of these subsidies opens the door to retaining all eight. How do we retain some of these credits and not operate in hypocrisy? The longstanding Republican position has been to allow the market to determine energy production. If every faction continues to defend their favored subsidies, we risk preserving the entire IRA because no clearly defined principle will dictate what is kept and what is culled.“

Iberian power outage – reverse Dunkelflaute?

Posted in climate, energy policy, Wind Energy, tagged , , , , , , on April 30, 2025| Leave a Comment »

Die Dunkelflaute or dark lulls have drawn attention to the need for dispatchable power (typically from gas turbines or coal-fired power plants) when the weather isn’t cooperating.

The massive power outage in Spain and Portugal on Monday may be the result of the opposite challenge – a surge in solar power supply greatly exceeding demand (dark line in chart below).

Note that no extreme weather events were reported in Spain on April 28, 2025. The Portuguese grid operator mentioned “extreme temperature variations” in Spain’s interior, possibly causing grid oscillations, but no storms or heatwaves were noted. Weather was typical for April, with mild temperatures (8-19°C) and some rain.

Meanwhile, the political focus in the US (chart below), and perhaps more so in Europe, had been on “clean” rather than reliable power.

Bottom line: Over-reliance on highly variable wind and solar power challenges grid management, putting supply reliability at risk.

Natural gas for the win! đŸ†

Posted in climate, energy policy, natural gas, Offshore Energy - General, tagged , , , , , , , on April 24, 2025| Leave a Comment »

All rankings are suspect, especially those I agree with 😉. The full scoreboard report is attached, so you can judge for yourself.

I was an early advocate for the use of natural gas in improving urban air quality. (I still have the ancient graduate school paper! 😀). This blog has repeatedly saluted natural gas and its compelling economic and environmental benefits.

Although combustion of natural gas emits 30% and 45% less CO2 than oil and coal respectively, the CO2 emissions are still significant. As a result, those who focus solely on greenhouse gases and ignore all other impacts (e.g. other air pollutants like NOx, SO2, and particulates, land use and space preemption, visual effects, and wildlife risks), want to limit the production and use of gas. However, whether or not fossil fuel consumption is significantly affecting the climate, the use for natural gas will be economically and environmentally imperative for the foreseeable future.

Not all natural gas production is equal from an environmental standpoint. Because this is an offshore energy blog, I draw your attention to the unique advantages of offshore gas production: minimal visual impact, bird friendly (rigs-to-roosts!), no risks to freshwater aquifers, and few land use issues.

Currently, most offshore gas production is in the form of oil-well gas (AKA associated or casing head gas). Offshore gas production is thus being primarily driven by oil demand, and is an added benefit from deepwater oil development.

Offshore gas-well or non-associated gas is largely the domain of independent operators producing in the shallower waters of the continental shelf. Non-associated gas has an added benefit in that there is little or no spill risk (depending on how dry the gas is). Shelf gas platforms also provide ecosystem benefits through their reef effect (rigs-to-reefs). Sustaining this non-associated gas production is therefore desirable from both energy and environmental standpoints.

Irrational exuberance revisited – the record breaking February 2022 Atlantic Wind sale

Posted in climate, energy policy, Offshore Wind, tagged , , , , , , , on April 21, 2025| Leave a Comment »

Bidding at the February 2022 Atlantic (NY/NJ) wind sale seemed incomprehensible given the economic and political uncertainties associated with offshore wind development.The 6 leases garnered bids ranging from $285 million to an astounding $1.1 billion, with total high bids of $4.37 billion! The Administration’s victory message correctly boasted that this was the “nation’s highest grossing competitive energy lease sale in history.”

The intense bidding was driven by the lure of subsidies, guaranteed power sales, unprecedented Federal and State promotion, peak climate activism, inattention to mounting public opposition, and irrational expectations regarding the role of offshore wind in powering the regional economy.

That wind bubble has since burst, as demonstrated by the lackluster (at best) August 2024 Atlantic sale, the disinterest in Gulf of America wind leases, and recognition of the costly realities of floating turbine projects in the Pacific. Any air that remained in the balloon was released following the Presidential election.

The table below summarizes the sale results and the current status for the 6 leases issued following the 2/2022 sale. One lease has been essentially terminated by the partners and the State. The other leases are in holding patterns in the planning phases.

The first US commercial offshore project, Vineyard Wind, has proven to be a major step backward for the wind industry. After being granted questionable financial and quality assurance waivers to reduce costs and “allow Vineyard Wind to adhere to its construction schedule,” the July 2024 turbine blade failure and subsequent lightning strike have raised new questions about the technology, industry, and regulatory regime. The report on the blade failure, which should arguably be a precursor to the resumption of Atlantic wind development, has yet to be released.

The one shining light, relatively speaking, for Atlantic wind development, has been Coastal Virginia Offshore Wind. That large project is on track to be completed at the end of 2026. Although the cost has risen about nine per cent, to $10.7 billion, that increase is understandable given the higher than anticipated costs for upgrading the onshore network.

GAO seems to think more consultation and staff will resolve offshore wind issues

Posted in climate, energy policy, natural gas, Offshore Energy - General, Offshore Wind, Regulation, tagged , , , , , , , , , on April 16, 2025| Leave a Comment »

The Government Accountability Office report on Offshore Wind Energy (full report attached) does a good job of summarizing the potential impacts from offshore wind development. They are categorized in the report as follows:

  • Marine Life and Ecosystems (see table pasted below)
  • Fishing Industry and Fisheries Management
  • Economic Development and Community Impacts
  • Tribal Resources, Including Sacred Sites and Established Fishing Grounds
  • Defense and Radar Systems
  • Maritime Navigation and Safety

Unfortunately, GAO’s recommendations, which focus on consultation and staffing (perennial favorites), are rather meaningless. Does GAO really think more consultation will resolve the fundamental concerns of the tribes and fishing industry? Does GAO really think increasing BOEM/BSEE staff is a solution? Wind was the signature offshore energy program of the previous Administration, and it was well resourced.

When the legislation authorizing offshore wind energy development was drafted, we envisioned energy alternatives that could complement thermal energy sources like gas, coal, and nuclear plants. Natural gas plants are particularly important to intermittent energy sources, because their power can be readily dispatched on demand.

Never did we expect attempts to ban the dispatchable energy sources on which renewable energy goals were dependent. Policies that limit gas production, transportation, and consumption don’t boost offshore wind development, they doom it.

In a rush to achieve the Administration’s energy goals, the wind leasing program brushed aside important economic, safety, national security, and environmental issues. Coastal residents, tribes, fishing interests, power customers, and other affected parties have rebelled. Their concerns won’t be smoothed over by increasing consultation.

So now the wind program is in a dark and windless place (a regulatory dunkelflaute?). Five projects are under construction or in the early stages of operation. Construction has been authorized for 6 other projects. Five more projects are in various stages of permitting. What next?

Meanwhile, we still haven’t seen a report on the ugly and embarrassing Vineyard Wind blade failure offshore Nantucket last July. Shouldn’t that report be a precursor to further offshore wind development in the US Atlantic? Also of note, that same turbine was struck by lightning 2 months ago.

Should directed suspension orders be issued pending a complete review of the wind program? If so, for which leases and for how long? Suspension of projects still in the permitting phase would be relatively painless and maybe even attractive given the current state of the wind industry. However, financial impacts for projects in the construction phase would be significant. These important next-step decisions need to be made soon. Muddling along is not a strategy.

Table 2: Examples of Potential Impacts of Offshore Wind Development to Marine Life and Ecosystems

ImpactDescription
Acoustic disturbanceConstruction and survey activities produce underwater noise that can disturb sensitive marine species. Offshore wind projects take measures to mitigate underwater noise, including the use of bubble curtains to dampen pile driving sound and pausing operations if protected species are sighted.
Changes to marine habitatInstallation of infrastructure, such as turbine foundations and transmission cables, introduces new structures and causes changes to the ocean floor that can alter marine habitat and affect the distribution, abundance, and composition of marine life in the area. These new structures can create artificial habitat that may benefit some species while displacing others and could affect bottom-dwelling species through disturbing the seabed. Artificial habitat effects of wind turbines are well documented, but research is ongoing to monitor and understand impacts on marine life.
Hydrodynamic effectsOperation of wind turbines can affect hydrodynamics and ocean processes such as currents and wind wakes, but little is known about regional effects of widescale deployment on ecosystems.
Vessel disturbanceVessels can disturb some species and pose strike risks to large marine animals, but the increase in offshore wind vessels is projected to be small compared to the total volume of vessel traffic. Offshore wind vessels are required to take measures such as following speed restrictions and employing protected species observers.
Entanglement riskStructures, such as mooring cables from floating wind turbines, could snag fishing gear and other marine debris and create entanglement risk to marine animals. Wind projects employ measures to minimize entanglement (e.g., mooring systems designed to detect entanglement), but there is uncertainty about the extent of the risk from floating turbines because of limited deployment.a
Collision risk to birds and batsTurbine blades pose a collision risk to some sea birds, but little is known about offshore collision risk to bats. Research on collision risks and mitigation measures (e.g., lighting and curtailment) is ongoing.

Cato: “The False Economic Promises of Offshore Wind”

Posted in climate, energy policy, Offshore Wind, tagged , , , , , on April 12, 2025| Leave a Comment »

Analysis by Jonathan A. Lesser:

“Of all commercial renewable generation technologies, offshore wind is the costliest, far more so than solar photovoltaics and onshore wind. The newest incarnation of offshore wind—floating turbines that can be sited in deep water—are more expensive still. Although offshore wind is supposed to benefit from more prevalent ocean breezes, it remains, like land-based wind and solar power, an intermittent source of electricity. Hence, as offshore wind comprises a larger share of total electricity capacity, it requires ever more backup generation or storage to compensate.”

“Offshore wind’s high cost and intermittency raise a simple question: Why have renewable energy advocates and policymakers in many Atlantic Coast states, as well as those on the West Coast, placed such emphasis on this technology? One justification, like all forms of renewable energy, is that offshore wind will reduce U.S. greenhouse gas emissions. Whether that is true remains an open, empirical question. Offshore wind’s high costs, which require substantial—and increasing—taxpayer and ratepayer subsidies, will raise electricity rates and reduce electricity consumption. Even offshore wind manufacturers such as German-based Siemens Energy admit this. By itself, reduced electricity consumption may reduce greenhouse gas emissions slightly, as will offshore wind replacing lower-cost natural-gas-fired generation. However, any such reductions will be so small as to have no measurable effect on climate.“

Good news! Woods Hole study finds that the AMOC has NOT declined in the past 60 years. Let’s party! đŸ˜€

Posted in climate, tagged , , , on March 24, 2025| Leave a Comment »

WHOI graphic: The AMOC not only distributes the ocean’s heat, moisture, and nutrients, but regulates the Earth’s climate and weather.

Contrary to alarmist forecasts that climate change could cause the Atlantic Meridional Overturning Circulation (AMOC) to collapse as soon as 2025, an important Woods Hole study found that the AMOC has not declined in the last 60 years.

“Based on the results, the AMOC is more stable than we thought,” co-author Linus Vogt said. “This might mean that the AMOC isn’t as close to a tipping point as previously suggested.”

Of course, the usual caveat about past performance not necessarily being predictive applies:

Co-author Nicholas Foukal: “That doesn’t say anything about its future, but it doesn’t appear the anticipated changes have occurred yet.”

Perhaps the urgent warnings about the collapse of the AMOC, if not unfounded, were at least premature.

S&P Global on the economic and environmental benefits of natural gas

Posted in climate, energy, natural gas, tagged , , , , on March 13, 2025| Leave a Comment »

While a graduate student more than 50 years ago, I wrote a paper entitled “The Use of Natural Gas in Improving Air Quality.”  My professor, Dr. Richard Gordon (RIP), a terrific economist who greatly influenced my thinking about energy, liked the paper but thought I was too optimistic about the availability of gas. 

The sense at the time was that natural gas was a premium energy source in short supply. I was blissfully ignorant and thought we geologists and petroleum engineers would find and produce the gas. The Shale Boom, for which I can take zero credit, has proven me correct, so I’m taking another victory lap. 😀

Last week, the great Dan Yergin and his team at S&P Global issued a report that explains how economically and environmentally important natural gas has become. Key findings from the report are pasted below:

Environmental Benefits:

  • Higher US LNG exports lead to lower overall global emissions by displacing the more GHG intensive fuels that would replace them.
  • End use combustion is responsible for 57–87% of GHG intensity for coal, oil, gas and LNG, with supply chain methane emissions the key driver of variation between fuels (e.g., domestic vs. international LNG, domestic versus piped natural gas imports, or different crude oil streams).
  • Coal emits roughly 70% more greenhouse gases than the US LNG it would replace across all the alternatives analyzed.

Economic Benefits:

  • US LNG’s unprecedented growth is enabled by an extended cross-state value chain, that reaches beyond the core-producing states – about 90% of every dollar spent remains within United States supply chains
  • Of the annual average of 495,000 US jobs supported through 2040, 37% will be in non-producing states. As many jobs will be supported in on-producing states as in Texas
  • Over the same period, LNG Exports will contribute $1.3 trillion in GDP, with $383 billion or 30% in non-producing states. On a per capita basis, producing states benefit from a cumulative $13.2K GDP per capita
  • The US Northeast (NE) has vast amounts of low-cost gas reserves in the Marcellus and Utica formations (New York, Pennsylvania, West Virginia, Ohio), sufficient to meet nationwide demand for ~17 years
  • Due to pipeline constraints these reserves are being developed at a suboptimal rate, pushing gas prices at Boston, Chicago and New York City Gates up 160% higher than the national gas market in peak months
  • Expanding NE pipeline capacity by 6.1 Bcf/d could reduce HH gas prices by $0.20/MMBtu and significantly lower prices across the region. Cumulative nationwide consumer savings could reach $76 billion through 2040

Should you be interested in learning more, the above findings are well supported by detailed information in the report.
