America has a serious oil deficit.  We consume almost three times as much oil as we produce.  As a result, we send more than $250 billion a year offshore (mostly to our enemies and other bad guys) to import oil so we can keep our trains, planes, and automobiles running.

On the other hand, America now has a huge surplus of natural gas, enough to last us for 100 years or more. If we replaced the oil we import with domestic gas, we could end our energy dependence and stop enriching U.S. adversaries.  But rather than convert from oil to gas, plans are afoot to export the gas!

The economics of importing oil and exporting gas make no sense.  We currently pay about $100 to import a barrel of oil.  We are exporting natural gas at a price that has the energy equivalence of about $25 a barrel.  That’s right, we are buying energy as oil for $100, selling the same amount of energy as gas for $25.

Buying high and selling low – this is what passes for national energy policy today. Our leaders should be embarrassed.

In addition to the economics, the strategic implications of converting from oil to gas are huge.

About two-thirds of the oil we use is for transportation.  Converting our transportation fleet to natural gas would almost eliminate the need to import oil.  Our trade deficit would be cut in half, petro-despots would be deprived of their largest revenue source, and our economy would get a $250 billion shot in the arm – every year.

So why aren’t we doing it?  Converting gasoline and diesel engines to gas is relatively easy and very safe.  The challenge is the infrastructure – a national network of filling stations that need to be in place before people will convert their cars and trucks to gas.  Building that infrastructure requires such a huge effort and coordination among so many actors that it is unlikely that the private sector can or will make the switch by itself.  Among other things, investors will worry that OPEC will defensively collapse the price of oil as they did in the ’70s.  Given these market realities, the only way this switch can possibly happen will be if the government steps up to catalyze and help underwrite the effort.  150 years ago the government made a similar commitment to enable the trans-continental railroad – which ushered in America’s great industrial expansion.  Converting to natural gas could bring about a similar economic boom.

Installing the required new fueling infrastructure for gas-propelled vehicles would be a tremendous generator of new jobs.  There are few other investments the nation could make with as large a payoff across so many areas of national concern.

For those interested in the math:

One barrel of oil = about 5.6 million BTU.  One Mcf of natural gas = about 1.02 million BTU.  (The actual energy content varies slightly depending on the grade of the oil or gas.  These are industry averages.)

Energy equivalence:  The BTUs in 1 bbl. oil = The BTUs in 5.6 Mcf natural gas.

1 bbl oil costs $96.75 and the same amount of energy in gas costs $25.59  (5.6Mcf  x $4.57),

The energy cost ratio between oil and gas is roughly 4  ($100/$25).

That means we’re paying 4 times as much for an oil BTU as we get when we sell a gas BTU.

It also means that once we have completed the conversion, operating on gas instead of gasoline will reduce our transportation energy costs by almost 75 percent.

Natural Gas Reconsidered

by Roger Cooper

During the past few years, the United States has received an unexpected energy windfall: put simply, we have a lot more natural gas than we previously thought. This realization is altering America’s energy future in a fundamental way. For many years, the conventional wisdom was that natural gas would play an important role as a bridge fuel but then fade away as the U.S. and the world turned to renewable sources of energy later in the 21st century.

Recent discoveries of enormous gas reserves in the United States offer a very different vision for the future of natural gas. Expanding domestic production will resolve the primary issue that is presently keeping natural gas from becoming the dominant energy resource in the U.S.: the inadequacy of supplies to guarantee long-term availability at reasonable and predictable prices. Yet a recent report by the MIT Energy Initiative estimates that U.S. reservoirs may contain enough natural gas to meet demand for 90 to 100 years at current consumption levels with much less price volatility.

New technology enabling the extraction of natural gas from shale has been called the most significant energy innovation this century; this discovery has spurred the expansion of U.S. natural gas production. Technology developed primarily in the United States has made the dramatic expansion of U.S. natural gas resources possible. Further technical improvements may enable an even larger expansion of our natural gas resources. ExxonMobil, a company nearly synonymous with oil, now predicts that natural gas will be the fastest growing major fuel source worldwide through 2030. Clearly, something very significant has happened in the world of energy.

The Eastern European Energy Void: A Case For American Leadership

Wednesday, September 29th, 2010
Jim Arkedis



Jim Arkedis is the director of PPI's National Security Project.

by Jim Arkedis

Parts of Hungary may well still conjure drab images of the Cold War: bleak and desolate wheat fields, maybe a blue-gray sky, skeletons of Soviet-era construction.

Stereotypes, of course, often contain a grain of truth. The New York Times’ recent profile of Oroszlany, some fifty miles east of Budapest, harks back to that bygone era.  Some 3,000 of the town’s 20,000 residents work in industries related to coal; with that many directly tied to the industry, it’s not hard to imagine how deep into the economy coal’s tentacles stretch.

But that’s changing — authorities announced that Oroszlany’s coal mine would close within three years.  The mine’s closure is well-intended, as the European Union — of which Hungary became a member in 2004 — seeks to end government subsidies for carbon-producing sources of energy.  Dirty coal is, of course, a chief protagonist.

This noble clean-energy goal has created a painful short-term “bridging” problem: The coal-fired power is disappearing too fast, and Hungary is left with an energy shortfall. It simply doesn’t produce enough domestic power right now to keep up with demand.  Figuring out any role that the U.S. or EU might play as Eastern Europe makes this transition is becoming ever more important.

This energy transition is an issue Gabor Rajnai, Oroszlany’s mayor, understands all too well. He wonders how his town is going to keep warm in the winter.  He frets Russian natural gas will fill the gap.  Rajnai probably remembers New Year’s Day 2006, when Vladimir Putin, then Russia’s president, sent a shockwave across Europe when he directed Gazprom, the state energy company, to shut off the flow of gas to the Continent.  Thanks to a price dispute with Ukraine, Europe froze, as it did again when Russia slowed down gas supply again in March 2008.  To make up for this year’s drop in coal-fueled power, Hungary will again import Russia gas.

This is the latest in a deepening dependency.  In March 2008, Putin and Ferenc Gyurcsany, his then- Hungarian counterpart, signed a contract that deepened cooperation on natural gas projects, including Hungarian financing of a Russian pipeline through the country.  In other words, as NATO-member Hungary transitions to a cleaner fuel sources, it is lashing itself ever tighter to the world’s coldest petro-dictator.

Let’s hope this deal doesn’t end up putting Hungary on par with its Eastern European neighbor, the Czech Republic.  As detailed in a stunning mid-September article in The New Republic, Russia and Gazprom camouflaged a network of Czech shell companies to obfuscate the money trail that leads directly from Prague’s hand to Moscow’s mouth.

The Czech Republic faces the same bridging problem as Hungary, too: As coal plants are phased out, how will the country power itself before domestic, self-sustaining energy sources are brought online?  Nuclear power, as regularly championed by PPI, is an option, but as TNR chronicles, even the Russians are likely to win that bid too.

However, that doesn’t mean Hungary and the Czech Republic are doomed to fall in some sort of Cold War-style Soviet sphere of influence.  According to one industry expert, the region’s long-term prospects of creating secure domestic energy sources are more solid: Alex Cranberg of Aspect Energy thinks Hungary has solid reserves of its own gas yet to come online.

He told me he was first drawn to Hungary because its geological fingerprint reminded him of the southern US, and thinks the country’s natural gas industry — where Aspect has invested — is well-run and could produce a stable supply of clean natural gas over the long-haul.  The trick, he says, is getting to the tough-to-reach underground gas fields, which make up some 90 percent of the domestic supply.  That appears to be happening: in the last four years, Cranberg claims that his joint venture has gone from producing none of Hungary’s natural gas to 20 percent, and that slice of the pie should only grow.

But growing takes time, and ensuring that Hungary — and Eastern Europe — has access to a diverse supply of energy in the interim is an important policy initiative that Brussels, not to mention Washington, seems to have glossed over.  Vice President Biden was in Prague to lobby for Westinghouse’s nuclear bid, but local experts believe it might be too little too late. Helping develop domestic clean power sectors could be a productive initiative for both capitals, from economic, energy, and security perspectives.

Cheat Sheet for Climate Policy: Part IV – What’s Not Important for a Good Climate Bill

How to tell a good climate bill from a bad one? This series will guide you through the main issues that are likely to arise in the coming weeks as the Senate takes on climate change. In previous posts, we looked at the crucial, the merely important and the negotiable elements in a climate bill. In this post, the last in the series, we highlight issues that might be popular or politically important, but which actually don’t matter that much for climate results. (To see all the posts in the series, click here.)

As with any big issue in Washington, climate policy has its share of sideshows and special-interest pet projects. If somebody’s favorite policy can be plausibly (or even implausibly) tied to climate, it’s a good bet they’ll attempt to do so. Conversely, if someone wants to hijack the climate debate, they may try to attach an unpopular issue to it. There are also a good number of perfectly well-intentioned ideas that, in reality, won’t make much difference in terms of climate policy.

Our goal in this post is to identify these issues: those that we feel are just political distractions, and those that won’t make much difference. If you’ve followed climate policy, you might find some surprises here — we include some issues that are often trumpeted as important. Not all of the policy proposals we mention are necessarily bad. Some are, but others are just not that important and will not have much effect on emissions reductions or the cost to the economy.

Category IV Issues: The Bad, the Irrelevant and the Trivial

#1: Renewable portfolio standards

A renewable portfolio standard (RPS) is a requirement that a certain percentage of electricity supplied by power companies come from renewable sources: wind, solar, geothermal and sometimes hydro or nuclear. A majority of states have an RPS in place, but there is no current federal standard. Many climate proposals, including Waxman-Markey, include an RPS.

Superficially, the idea is appealing: by forcing power suppliers to use renewables, an RPS expands the market for them. This will obviously increase their use, reduce emissions and encourage innovation in renewable techs.

The problem is that once you have a carbon price, moves to renewable energy sources should happen anyway, making an RPS redundant. Since burning fossil fuels becomes more expensive, power suppliers will shift to cleaner technologies. Some of this switching will be to renewables, while others will be to cleaner fossil fuels like natural gas – a fuel that is excluded in most renewable portfolio standards.

If the standard is set at a level lower than the amount of renewables that power companies would shift to anyway under a carbon price, then an RPS is totally irrelevant: companies would meet the standard just by acting in response to the price. But if the standard is set at a level higher than the amount of renewables utilities would use, an RPS imposes additional costs. Power companies that would like to switch to cheaper and clean(er) technology — like natural gas or nuclear (if it’s not included in the RPS) — would be limited in their ability to do so by an RPS. Instead, an RPS would force them to use more expensive renewables in their efforts to make their emissions targets. Those costs get passed on to consumers, making climate policy more expensive.

And here’s the thing: it would be costlier without providing any additional emissions benefits than what we would get under a cap. An RPS is often favored by environmental groups (and, of course, firms with investments in renewables) presumably because they think a carbon price will be too low to achieve the level of clean energy use they prefer. But this doesn’t make much sense. The cap set by a climate policy determines the environmental outcome; all an RPS would do is restrict the ability of power companies to decide how to meet that cap. In other words, an RPS doesn’t result in lower emissions. If you want that, you need to go back to Category I — set a tighter cap (or a higher carbon tax).

Note that the fact that an RPS is a bad idea doesn’t necessarily mean that government investment in R&D for renewables is unwise — such investments are responses to identifiable market failures. But an RPS would be a poor remedy for those failures.

#2 Preempting the EPA

The Environmental Protection Agency (EPA) has some authority under existing laws to regulate greenhouse gases. The Supreme Court definitively established this in its famous Massachusetts v. EPA decision in 2007. Under President Obama, the agency has already started regulating greenhouse gas emissions from cars and trucks, and is moving towards regulating emissions from so-called “stationary” sources, power and industrial facilities. If Congress fails to act on climate, the EPA will continue down this path.

If Congress does pass a new law, how should that law deal with the existing EPA authority? The majority (though not consensus) view on the Hill appears to be that new legislation should preempt this authority. Waxman-Markey would explicitly remove the EPA’s authority under the Clean Air Act to regulate greenhouse gases from stationary sources (but would leave regulation of vehicles intact). Preliminary indications are that the Senate bill would do the same.

Many environmental groups oppose this preemption, claiming that EPA authority is needed in case the climate law does not go far enough. Again, this doesn’t make sense. First, EPA authority isn’t a kind of reserve power, to be used only when a new law appears inadequate. If Congress passes a new climate law but leaves existing EPA authority intact, the EPA will still be legally required to regulate greenhouse gases. Waiting to see if the new climate bill is “good enough” before taking action won’t work: the Bush EPA advanced similar arguments in Massachusetts v. EPA and lost. In other words, preempting the EPA isn’t like discarding a useful tool — it’s like turning off a machine. New climate legislation is a better machine.

Second, where the EPA does have discretion, it needs the political will to act. The moves that the EPA is currently making to regulate greenhouse gases are highly controversial. It has taken years (arguably decades) of congressional inaction on climate for the EPA to use its exisiting authority to regulate greenhouse gases. If there is a new climate law, it will likely sap the agency’s will to act further on climate even if authority is not preempted. In that environment, it is hard to see the administration devoting resources and political capital to additional regulations (beyond the minimum that is legally required) for the foreseeable future.

In short, there are some things the EPA must do, and a new climate bill cannot change that without preempting agency authority. There are other things the EPA has control over, but action on those areas will be unlikely for political reasons once a climate law has been passed. If environmental groups feel that the climate proposals under consideration don’t go far enough, they should make an effort to convince legislators — and their constituents — of that. The move to preserve the EPA as an alternative venue for their arguments is understandable, but a little cynical. The time for the climate policy debate is now (we hope), and the venue is Capitol Hill.

#3 Preempting the states

Like the EPA, states have made moves to regulate greenhouse gases in the absence of action from Congress. California’s AB32 law (which commits California to reducing emissions to 1990 levels by 2020) and the creation of a Regional Greenhouse Gas Initiative, a regional carbon market by some states in the Northeast, are the most notable examples.

How should a federal climate law treat these regional and state efforts? Should they be allowed to continue, or should federal law preempt them?

The basic answer is similar to that for renewable portfolio standards: state-level regulation makes sense now, but is mostly useless or even counterproductive if there is a national carbon price. As Robert Stavins recently explained, state-level greenhouse gas regulation that is stricter than the national cap doesn’t reduce overall U.S. emissions — it just forces emissions out of the regulating state into one without climate regulation. This drives up prices in the regulating state without any climate benefit.

Preemption of state greenhouse gas regulations therefore probably won’t have any negative impacts for emissions and climate. Stavins points out that there still may be benefits for smaller state-level regulations in situations where a low federal carbon price fails to push beneficial changes. That’s true, but so long as the new federal law has a serious emissions cap, preempting major regulations like AB32 and regional carbon markets is fine. Industry wants this preemption since they’d rather have a single set of rules to comply with. It’s a concession that policy-makers can make at little or no environmental cost.

#4 Wall Street

Wall Street does not have a very good reputation right now. Creating a new market for carbon allowances means new opportunities for brokering trades between emitters — and with that market, possibilities for speculation, new financial instruments such as derivatives and possible opportunities for abuse. Some on Wall Street certainly see carbon as just another commodity and carbon markets as a big opportunity.

But while derivatives have been called financial weapons of mass destruction, they can play an important role in future carbon markets. Firms will need some kind of mechanism to protect against the risk of unforeseen events that cause them to be out of compliance with the cap, such as emergency fuel-switching or inaccurate emissions accounting. Since regulated firms are exposed to such risks, they will look to reduce that exposure through insurance in the form of carbon derivatives. The market must be properly regulated (the rules can be written directly into climate legislation), but assuming it is, the benefits of reduced transaction costs and improvements in liquidity that financial expertise can bring seem likely to exceed the costs of possible fraud or abuse.

Some of the criticism may arise not from a fear that the government will be unable to prevent criminal or undesired activity, but from opposition to creating a new market (and new profit opportunity) for Wall Street. As Michael Levi points out, however, somebody has to run a carbon market, and they had better have expertise. For all its recent failings, Wall Street firms have world-class market-making expertise. Oversight is necessary, but keeping the best financial minds away from carbon simply because they’re unpopular right now is likely to be costly.

#5 Drilling and energy security

One touted benefit of a climate policy that reduces reliance on fossil fuels is that it improves American energy security. This is easy to understand: oil comes from somewhere else, and if we use less oil, we won’t import as much. This improves our trade deficit and reduces reliance on unstable parts of the world for energy.

All of that is a good thing, but it’s a side benefit — it has nothing to do with climate. Indeed, policies that improve energy security might or might not have climate benefits. Putting a price on carbon certainly will, but increasing domestic oil supplies by expanding drilling won’t — it will either replace imports and have no overall effect on emissions or it may drive down (ever so slightly) the price of oil, which will increase consumption and emissions. If domestic drilling does not result in increased emissions, it is not necessarily a bad idea, but it can’t be justified on climate policy grounds.

Drilling is an energy issue, not a climate one. But climate legislation itself has been framed as being about energy (and, specifically, energy security) as much as it is about climate change. That’s not unexpected, and it will similarly be no surprise if climate legislation includes provisions to expand drilling, though how the political dynamics of the Gulf Coast oil spill play out over the next few weeks will determine what, if anything, is included. The point is that these provisions are political — they are in there to attract support for the bill or placate opponents, not for any climate benefits.

The Bottom Line

As the Senate tackles climate legislation, numerous provisions and elements are likely to be raised. Be wary if the conversation begins to get bogged down around the following questions:

  1. Does the bill have renewable portfolio standards?
  2. Does it preempt EPA authority?
  3. Does it preempt state regulations?
  4. How does Wall Street come out?
  5. Does the bill tackle our energy security problems?

These questions are largely distractions to the ultimate objective of a climate bill: reducing greenhouse gas emissions as much as possible at the lowest possible cost. If you care about climate change, keeping your eyes on that end goal will be crucial if there is to be any hope of untangling the legislative thicket and passing a meaningful climate bill this year.

Energy Realism and Hype

Thanks to new drilling techniques, U.S. natural gas reserves may have doubled, Energy Secretary Steven Chu announced this week. “That’s a big deal because it will be a transition fuel as we go to renewables,” Chu said at a conference hosted by the U.S. Energy Information Administration.

Chu’s emphasis on natural gas as a bridge fuel, together with President Obama’s decisions to allow offshore drilling and expand loan guarantees for building nuclear power plants, attest to a new realism in U.S. energy policy. The Obama administration is trying to move the deadlocked energy debate beyond a false choice between fossil and renewable fuels. For now, America needs more of both.

This “no fuel left behind” approach also lays the groundwork for bipartisan cooperation on capping carbon emissions. If Republicans say “no” to things they’ve long demanded, namely more nuclear power and offshore drilling, as part of a comprehensive climate bill, it will be another sign that they are unwilling to help solve the country’s biggest problems.

Some environmentalists (including, apparently, Al Gore) are chagrined over Obama’s support for offshore drilling, which they see as a concession to the “drill, baby, drill” right.  So let’s be clear: offshore production in U.S. waters will not lead us to “energy independence,” nor will it lower prices at the pump. Our share of the world’s oil reserves — even if much more is aggressively produced — is still not large enough to move global oil prices. This would be the case even if there was a truly competitive and free global petroleum market. But the global oil market is not free and competitive — it is dominated by low-cost producers in the Persian Gulf, who are aligned in a cartel and could easily counteract any downward price influence from an increase in U.S. supply. The only way that U.S. oil could directly and dramatically lead to low U.S. gas prices would be for us to adopt the Venezuelan model: nationalize the industry, close the borders, and grossly subsidize the industry. Not gonna happen.

Nonetheless, modest expansions of domestically produced oil would yield modest benefits. Estimates range from a low of 39 billion barrels of recoverable oil to a high of 63 billion barrels. “If ramped up quickly enough, that could overcome the underlying decline rate of current U.S. output and add significant net production for a decade or two, at a time when competition for the oil we are currently importing is likely to be fiercest,” writes energy consultant Geoffrey Styles.

In addition to marginally reducing our reliance on foreign imports, offshore drilling would create U.S. jobs and lower our massive energy trade deficit. These benefits shouldn’t be exaggerated, but they certainly aren’t negligible. Further, to the extent that our offshore development leads to large and cost-effective finds of natural gas, that is almost certainly a good thing since unlike oil, gas is not as subject to global price pressures or oligopolistic manipulation as is oil. Moreover, to really reduce our greenhouse gas emissions, the United States will have to substitute baseload gas for baseload coal on a large scale and abundant gas developed in an environmentally acceptable fashion (more likely to apply to offshore development than to much of the contemplated onshore development of “unconventional” sources) is a key to that goal.

What about the environmental risks of drilling? Without question, the history of petroleum development and delivery is rife with calamities. The decades-old Santa Barbara spills are still seared into the minds of many and, of course, the Exxon Valdez has not – and should not – soon leave our collective memories. But the former was decades ago and the latter is a compelling argument for even stronger protections in the transportation of petroleum. The next Exxon Valdez could be carrying oil from onshore or offshore sources. But the technology and regulation of offshore production has greatly improved since Santa Barbara, and while one could compellingly argue for even more protections, the fact is that offshore development is much less risky than ever before.

Finally, Obama has deftly maneuvered his political opponents into a tight corner. The White House understands that the paramount goal of energy policy should be to price carbon. That goal is unlikely to be achieved in Congress as long as conservatives continue to fantasize over a supply-side panacea that will lead American to a golden age of “energy independence” and “lower prices at the pump.” This is an energy policy of abdication and isolationism. By taking a balanced approach, Obama has challenged conservatives to take “yes” for an answer — or show that they really don’t believe in their alleged “alternative” path to energy security.

Scaling Up Natural Gas

Monday, February 22nd, 2010

by Elbert Ventura

Here at PPI, we’ve long argued that for the U.S. to meet its carbon reduction targets, we need to assume a “Leave No Fuel Behind” outlook. Currently, coal — the most polluting and the cheapest of sources — accounts for half of all power produced in the U.S. There’s no doubt that we need to scale back our use of coal. But replacing that base-load capacity will be a tall order.

Ramping up renewable sources like wind and solar should, of course, be a priority, but they simply won’t be reliable energy sources for decades to come. We’ve also argued for an expansion of nuclear power and more research into carbon capture and storage, and we applaud the administration’s recent efforts to jumpstart our nuclear industry. But let’s not forget the quickest interim source we can use to begin cutting back on coal emissions: natural gas.

In a column last Friday, the Washington Post‘s Steven Pearlstein makes a compelling case for scaling up natural gas:

The silver bullet: Decommission about two-thirds of the electric-generating capacity fueled by cheap and plentiful coal, and replace it with power generated from cheap and plentiful natural gas, which emits half as much carbon for each megawatt of electricity.

Pearlstein points out that a confluence of events — the overbuilding of gas-fired plants in the ’90s and an increase in supply thanks to new drilling techniques — has made natural gas a feasible substitute for base-load electricity generation. A Congressional Research Service study found that if our currently underutilized gas plants were to double their production, about a third of coal-fired power would be displaced — a major step toward meeting our emissions reduction targets.

In trying to wean ourselves off coal, the most effective method would still be to put a price on carbon. This week, the Senate is back from recess and will make a “last-ditch attempt” to put together a compromise cap-and-trade bill. But as legislators try to break the gridlock over cap-and-trade, they should keep their eye on alternatives that can begin to ease the grip of coal on our economy. Nudging utilities toward natural gas seems like a good start.
