Post image for Department of Energy Claims Climate Change Threatens Energy Sector

The Department of Energy last week released a report on U. S. Energy Sector Vulnerabilities to Climate Change and Extreme Weather. John Broder in the New York Times summarizes its findings:

“The blackouts and other energy disruptions of Hurricane Sandy were just a foretaste, the report says. Every corner of the country’s energy infrastructure — oil wells, hydroelectric dams, nuclear power plants — will be stressed in coming years by more intense storms, rising seas, higher temperatures and more frequent droughts.”

Broder goes on to quote Jonathan Pershing, deputy assistant secretary of energy for climate change policy and technology, who was in charge of producing the report: “We don’t have a robust energy system, and the costs are significant.  The cost today is measured in the billions.  Over the coming decades, it will be in the trillions.  You can’t just put your head in the sand anymore.”

Neither the Department of Energy’s report nor any of the news stories I’ve read consider the major reason why the energy sector is becoming less robust and resilient.  It’s largely because of all the regulations and mandates that require the energy sector to invest hundreds of billions of dollars in technologies that provide very little energy, which means that there is little capital available to invest in improving and enlarging the energy infrastructure.

In particular, the margin that provides electric reliability in times of stress to the system has been declining because electric utilities have been building lots of windmills and solar panels that provide small amounts of unreliable and expensive electricity while preparing to close conventional coal-fired power plants that produce large amounts of reliable and inexpensive electricity in order to comply with EPA regulations. It’s not climate change, but climate change policies that are harming the energy sector.

Post image for How Much Warming Will the President’s Plan Avert? (Hint: It’s way too small to be detected or verified)

President Obama unveiled his Climate Change Action Plan at Georgetown University today. As expected, the President advocated carbon dioxide (CO2) emission standards for new and existing coal-fired power plants, tough new energy efficiency standards for homes and appliances, and federal support for private renewable energy investment on public lands.

Congress’s failure to approve his plan would have “a profound impact on the world that we leave behind not just to you, but to your children and to your grandchildren,” Mr. Obama contended.

The President’s plan, however, provides no specifics on the EPA’s pending power plant emission standards, nor does it estimate how many tons of CO2 emissions those standards will avoid or reduce.

Surprisingly, the 21-page plan contains only four emission reduction estimates. The administration’s fuel economy standards are projected to avoid 6000 million tons of CO2; appliance efficiency standards, 3000 million tons; heavy truck fuel economy standards, 270 million tons; and improved forestry practices, 140 million tons. The grand total of itemized CO2 reductions is 9,410 million tons.

How much climate change will that avert? Too little to be detected or verified.  [click to continue…]

Post image for President Obama’s Climate Speech: Pre-Game Commentary

This week’s National Journal energy insiders blog poses the question: “Should Obama Go Big on Climate Agenda?” What I’m about to post here is I would have posted there, except that I don’t know how to operate the new and improved self-publication program!

My title would have been: “Obama Should Upend Climate Agenda.” Here goes.

In his address tomorrow at Georgetown University, President Obama is expected to lay out a climate change action plan featuring carbon dioxide (CO2) emission limits for existing power plants, tougher efficiency standards for homes and appliances, and more renewable energy development on public lands.

There are strong reasons to oppose each element of this plan.

Renewable energy is costly, intermittent, and unreliable. If it weren’t a bad buy for consumers, Congress would not need to subsidize it (in perpetuity – if President Obama gets his wish), nor would 30 states and the District of Columbia need to mandate it.

Before environmentalists start cheering, they should remember that subsidized, mandated wind energy slices and dices vast numbers of bats and birds, including endangered species. The Obama administration has never fined or prosecuted a wind farm for killing a protected bird. As one former Fish and Wildlife official described the administration’s policy: “If you electrocute an eagle, that is bad, but if you chop it to pieces, that is OK.” Accelerating renewable energy development on federal lands will likely lead to more bat and avian mortality and a further retreat from honest enforcement of the Migratory Bird Treaty Act and the Bald and Golden Eagle Act.

As for appliance efficiency standards, the one thing they invariably do is limit consumer choice. From toilets that don’t flush to washing machines that don’t get clothes clean to automobiles that provide less protection in crashes, efficiency standards can make products less valuable even while making them more costly.

Proponents claim the payback in reduced electricity and fuel expenditures more than offsets the increase in purchase price. But if these technologies will save us money, why do we need a law forcing us to buy them?

Ironically, energy efficiency standards are an inefficient climate mitigation strategy.  A major review by the Breakthrough Institute concluded: “There is a large expert consensus and strong evidence that below-cost energy efficiency measures drive a rebound in energy consumption that erodes much and in some cases all of the expected energy savings.”

The administration’s proposed CO2 emission limits for existing power plants pose the biggest risk to consumer welfare and the economy. Like it or not, coal still provides the largest share of U.S. electric power. At best, CO2 emission limits make electricity more costly. At worst, they can destroy coal as an economically-viable electricity fuel and force coal power plants to shut down.

Let’s briefly review the unsavory history of this policy. [click to continue…]

Post image for Is a Carbon Tax a Conservative Idea Whose Time Has Come? Thoughts on the R Street – Heartland Debate

On Thursday, the R Street Institute and the Heartland Institute held a debate in a Washington, D.C. auditorium on the proposition: “Resolved: Under no circumstances should conservatives support a tax on carbon emissions.” About 150 people attended.

Arguing for the proposition were James Taylor of Heartland and David Kreutzer of the Heritage Foundation. Arguing against were Andrew Moylan of R Street and former Rep. Bob Inglis (R-S.C.) of the Energy and Enterprise Institute.

After the debate, moderator and Reason Foundation science correspondent Ron Bailey called for a division of the house. A majority of the audience opposed the proposition. The next day Bailey reported on Reason’s blog that “About 60% of Conservatives Support a Carbon Tax.” When this headline provoked the ire of some conservatives, Bailey said it was meant to be somewhat tongue in cheek.

Whether offered in jest or not, Bailey’s headline is false. Had he put the question to the 150 or so movement conservatives who attend Grover Norquist’s Wednesday Meeting, the head count might have been 148-2 — with only Moylan and Eli Lehrer of R Street standing in favor of a carbon tax.

Most people who attend carbon tax events in D.C. are ‘progressives.’ I suspect many who came to the debate were staunch carbon taxers and would not have stood for the proposition even if Taylor and Kreutzer dazzled with the oratory of Abe Lincoln and Dan’l Webster.

An unfortunate word choice may also have tilted the straw poll against the proposition. Prudence counsels us never to say never. In some circumtances, bad choices are the only way to avoid even greater evils. The categorical formulation (“under no circumstances”) made the proposition literally unreasonable.

Here’s what the debate was really about: “Resolved, a carbon tax is a conservative idea whose time has come.” That proposition is almost farsical on its face. Even some greenies in the room might have had to swallow hard before standing up for it.

Let’s review some of the back and forth.

Do carbon taxes pick winners and losers?

Inglis led off by arguing that a conservative energy policy does not “pick winners and losers.” What conservatives want is an “impartial cop on the beat.” That’s a carbon tax, which applies equally to all forms of energy and then lets the “free market” decide. Not so — not even close.

A carbon tax discriminates against carbon-based (fossil) fuels. That’s its core function! Inglis might as well say that a nuclear tax applies equally to all forms of energy and lets the free market decide. Just because the market sorts out the effects of a discriminatory tax does not make the tax non-discriminatory. [click to continue…]

Post image for Climate Models: “Epic Failure” or “Spot on Consistent” with Observed Warming?

NASA scientist Roy Spencer recently posted on his Web site some startling graphs produced by John Christy, his colleague at the University of Alabama in Huntsville. The graph immediately below compares the linear-trend temperature projections of 73 climate models with the linear trend of observed temperatures for the bulk tropical atmosphere during 1979-2012.

CMIP5-73-models-vs-obs-20N-20S-MT

The 73 models are part of the fifth phase of the Coupled Model Intercomparison Project (CMIP-5), a collaborative effort of 20+ modeling groups to inform the IPCC’s forthcoming Fifth Assessment Report (AR5). The Project’s three main objectives are to “evaluate how realistic the models are in simulating the recent past,” “provide projections of future climate change” out to 2035 and 2100, and “understand some of the factors responsible for differences in model outputs” such as different estimates of feedback effects.

Christy’s graph reveals what Spencer calls an “epic failure” of the models to match the actual behavior of the tropical atmosphere. Models that overestimate recent warming are likely to overestimate future warming as well.

Of course, observational systems may have biases and errors, but that is an implausible explanation for the mismatch. The observations come from two satellite and four radiosonde (weather balloon) datasets, which all independently give “virtually identical trends.”

What about the subset of U.S.-designed models — do they get the trend right? Nope. Take a gander at the next graph.

Post image for Where Does America’s Oil Come From? (An Update)

In 2005, 60% of all petroleum consumed in the U.S. came from imports. The conventional wisdom then and for several years thereafter was that America was fated to become ever-more-dependent on increasingly costly petroleum imports.

Peak oil alarm was in vogue, popularized by books such as Peak Oil Survival: Preparation for Life after Gridcrash (2006), Twilight in the Desert: The Coming Saudi Oil Shock and the World Economy (2006), A Crude Awakening: The Oil Crash – We’re Running Out and Don’t Have a Plan (2007), Hubbert’s Peak: The Impending World Oil Shortage (2008), and Confronting Collapse: Energy and Money in a Post Peak Oil World (2009).

M. King Hubbert, the originator of peak oil theory, correctly predicted in 1956 that U.S. domestic petroleum production would peak between 1965-1970. He also forecast a peak in global production by the late-2000s. In 2008, many commentators interpreted spiking crude oil prices as confirmation of Hubbert’s theory.

But Hubbert, who died in 1989, did not live to see the “shale revolution.” During the past decade, advances in directional drilling and hydraulic fracturing have made it economical to extract oil from the pores of rock. Although U.S. petroleum production is still lower than it was at its peak in 1970, it has increased every year since 2008 with no end in sight.

Citi GPS, a highly respected analytic group, argues that “surging supply growth” from fracked shale formations, deep-water wells, and Canada’s oil sands could “transform North America into the new Middle East by 2020.” Peak oil, if it exists at all, is likely decades away, not around the corner, as the books cited above assumed.

In a previous post, I discussed the Energy Information Administration’s  July 2011 analysis of U.S. dependence on foreign oil. The EIA updated its analysis in May 2013. What has changed?

Basically, there’s more of the same. Already by 2010, more than half of all the oil we consumed came from the U.S. But whereas the balance then was 51% domestic and 49% imports, the balance as of 2012 was 60% domestic and 40% imports (exactly the reverse of the percentages in 2005).

Post image for Social Cost of Carbon: Interagency Group Predictably Predicts Climate Change Worse Than Predicted

Hold the presses! A U.S. Government interagency working group has just released its updated Technical Support Document (TSD) on the social cost of carbon (SCC).

This is joyous news in some circles. “The ‘Social Cost of Carbon’ Is Almost Double What the Government Previously Thought,” Climate Progress enthuses. Why are they pleased? Because the higher the SCC, the stronger the (apparent) case for suppressing the production and export of hydrocarbon energy in general, and for blocking the Keystone XL pipeline in particular.

SCC is an estimate of how much damage an incremental ton of carbon dioxide (CO2) emissions does to humanity and the biosphere. SCC estimates are driven by assumptions about such issues as climate sensitivity (how much warming results from a given increase in CO2 concentrations), climate impacts (how warming will affect weather patterns and sea-level rise), economic impacts (how changes in global temperature, weather, and sea-level rise will affect agriculture and other climate-sensitive activities), and technological change (how adaptive capabilities will develop as climate changes).

Modelers feed the assumptions into computer programs called “integrated assessment models” (IAMs). By tweaking those values, the modeler can get pretty much any result he desires. Outcomes also vary based on the discount rate selected, i.e., how much people are assumed to value income in the future compared to income in the present.

Using three IAMs, three discount rates (2.5,% 3,% and 5%), and a fourth value representing low-probability catastrophic impacts, the interagency group calculates four SCC estimates for the year 2020. In the working group’s 2010 TSD, the SCC estimates were $7, $26, $42, and $81 (2007$). In the updated TSD, the corresponding estimates are $12, $38, $58, and $129 (2007$). Excuse me, but even for the high-impact projections, the updated estimate ($129) is 59% higher than the 2010 estimate ($81), which is more than a tad shy of “almost double.”

Let’s cut to the chase. Those who say the SCC is bigger than the government previously thought merely recycle the old saw that climate change is “worse than scientists previously thought.” They are mistaken. The climate change outlook is better than we have long been told.

One reason the updated estimates are higher is that the IAMs contain an “explicit representation” of sea-level rise “dynamics.” Are the modelers keeping up with the scientific literature? Consider two recent studies

  • King et al. (2012): The rate of Antarctic ice loss is not accelerating and translates to less than one inch of sea-level rise per century.
  • Faezeh et al. (2013): Greenland’s four main outlet glaciers are projected to contribute 19 to 30 millimeters (0.7 to 1.1 inches) to sea level rise by 2200 under a mid-range warming scenario (2.8°C by 2100) and 29 to 49 millimeters (1.1 to 1.9 inches) under a high-end warming scenario (4.5°C by 2100).

If 21st century sea-level rise is more likely to be measured in inches rather than feet or meters, shouldn’t SCC estimates decline?

And what about the 15-year period of no-net warming, which the climate science establishment did not predict and still struggles to explain? The warming pause is hard to square with the mantra of “worse than we thought.” It is evidence that the SCC is lower than they thought.

Let’s look at the disconnect between what they predicted and what happened.  The graph below comes from NASA scientist Roy Spencer[click to continue…]

Post image for ‘Unleash the Energy Export Revolution’ – Mark Mills

Today in National Review Online, Mark Mills has a terrific column titled “Unleash the Energy Export Revolution.” He begins by calling out the irrationality of our government’s current anti-energy export policy: 

On May 17, the Department of Energy (DOE) approved just the second license in America to export natural gas. Nineteen more applicants still wait. Yes, private businesses, willing to spend tens of billions of private capital, are lined up for a schoolyard game of “Mother May I” to get permission to export a product that the U.S. is uniquely good at manufacturing. So good, in fact, that America is now the world’s No. 1 producer, with no end in sight. What a world. 

Or, as comedian Yakov Smirnov might say, “What a country!”

Mills makes several salient points. [click to continue…]

Post image for John Christy: Climate Change Overview in Six Slides

Yesterday, Rep. David McKinley (R-W.Va.) hosted a climate change conference in a technology park in Fairmont, W.Va.

A mixed panel of warmistas and skeptics featured Marc Marano of Climate Depot, Scott Denning of Colorado State University, Jim Hurrell of the National Center for Atmospheric Research, Joe Casola of the Center for Climate and Energy Solutions, Annie Petsonk of Environmental Defense Fund, Myron Ebell of the Competitive Enterprise Institute, Dennis Avery of the Hudson Institute, and John Christy of the University of Alabama in Huntsville, who participated by satellite link.

I emailed Dr. Christy and asked for permission to post his presentation on GlobalWarming.Org; he promptly sent me the files.

Dr. Christy’s Power Point presentation is available here. The accompanying text is available here. The main takeaway points:

  • Popular scare stories that weather extremes — hurricanes, tornadoes, droughts, floods — are getting worse are not based on fact.
  • In the U.S., high temperature records are not becoming more numerous.
  • Climate models significantly overestimated warming during the past 15 years.
  • Even if climate models were correct, a 50% reduction in U.S. CO2 emissions by 2050 would avert only 0.07°C of warming by 2100.
  • If a policy is not economically sustainable, it’s not politically sustainable.
  • The climate change impact of enhancing CO2 concentrations has so far been small compared to the public health and biospheric benefits provided by affordable, carbon-based energy.
Post image for Solar Panel Concerns Fuel Worries about Reliability

By Anthony Ward, CEI Research Associate

Solar industry executives are worried about the reliability of their own products. In an article this week, the New York Times reports industry executives are becoming increasingly concerned about the rising number of solar panel failures. The average expected operational lifetime of a solar panel is 25 years, but some are failing in only two years. Increasingly, it seems that solar panels are becoming defunct earlier than anticipated.

According to the article:

The solar panels covering a vast warehouse roof in the sun-soaked Inland Empire region east of Los Angeles were only two years into their expected 25-year life span when they began to fail. Coatings that protect the panels disintegrated while other defects caused two fires that took the system offline for two years, costing hundreds of thousands of dollars in lost revenues.

It was not an isolated incident. Worldwide, testing labs, developers, financiers and insurers are reporting similar problems and say the $77 billion solar industry is facing a quality crisis just as solar panels are on the verge of widespread adoption.

No one is sure how pervasive the problem is. There are no industry wide figures about defective solar panels. And when defects are discovered, confidentiality agreements often keep the manufacturer’s identity secret, making accountability in the industry all the more difficult.

But at stake are billions of dollars that have financed solar installations, from desert power plants to suburban rooftops, on the premise that solar panels will more than pay for themselves over a quarter century.

Subsidies and the associated pressures to reduce costs, boost sales, and reduce government debt are the principal cause of the decline in quality:

After incurring billions of dollars in debt to accelerate production that has sent solar panel prices plunging since 2009, Chinese solar companies are under extreme pressure to cut costs. [click to continue…]
