Why We Still Need Innovation in Successful Clean Energy Technologies

Today is my last day at CFR. I’m joining ReNew Power, India’s largest renewable energy firm, as their CTO. I’m excited for a new adventure but sad to leave the Council, which has given me support and autonomy to study the innovations needed for global decarbonization. Read More

Is U.S. Fossil Fuel Policy Keeping Millions Poor?
Is the U.S. government keeping tens of millions of people poor by focusing its development assistance on renewables rather than gas and coal? It’s a critical question – particularly as the United States ramps up its Power Africa effort – that’s addressed thoughtfully by Todd Moss and Benjamin Leo in a new Center for Global Development paper that Bjorn Lomborg highlighted in a USA Today column this weekend. Moss and Leo estimate that OPIC (Overseas Private Investment Corporation) investment restrictions, which tightly cap the amount of money that can go toward coal or gas, are costing 60 million people access to electricity. But while I’m on board with their basic point – the world’s wealthy should avoid cutting greenhouse gas emissions on the backs of poor people when rich ones are still pumping out so much pollution – I’m skeptical of their bottom line. The Moss and Leo argument is straightforward. Every dollar committed by OPIC to a natural gas power project is accompanied by four dollars (on average) in private funds. In contrast, every OPIC dollar committed to a renewable energy project leverages only 50 cents on average. If OPIC has a ten billion dollar portfolio, dedicating that to gas would generate 50 billion dollars in investment, but directing it toward renewables would yield only 15 billion dollars. Moss and Leo combine these figures with an estimate of the per-person costs of energy access to conclude that focusing on gas could generate access for 90 million people but that investing in renewables would serve only 20-27 million. They also estimate the amount of generating capacity that each type of focus could yield: only 4,200 megawatts (MW) for renewables but 42,000 MW for one-third-less-capital-intensive natural gas. It strikes me that there are three issues with this analysis. Correcting two of them makes the trade-off look less stark, but fixing the third makes it look even worse. The first problem is with the leverage ratios. The historical leverage ratios do not tell us that for every additional dollar OPIC spends on gas the private sector will spend four. They actually tell us nothing about how much private investment a dollar of OPIC spending will leverage, because they don’t tell us what happens at the margin, and they don’t tell us anything about causality. To see why, imagine that private investors planned to spend a billion dollars on natural gas. Now imagine that OPIC stepped up and decided to commit ten million dollars to the same end – and that developers pocketed that money without expanding their projects. We would calculate a stunning 100:1 leverage ratio for this project, even though the actual leverage is zero. It’s entirely possible that public spending on natural gas projects appears to leverage more private capital than spending on renewables does simply because more private capital is already there for natural gas than for renewables. We have no idea, at least based on the numbers that Moss and Leo present, whether OPIC investment attracts more private capital when it’s in gas or in renewables. The second issue has to do with how costs are defined. Moss and Leo focus on power plant capital costs. Those are, to a good approximation, the full costs of renewables. But they also are, of course, far from the full costs of natural gas. (Generation costs for natural gas are typically dominated by the cost of fuel.) Now Moss and Leo note that most of the countries targeted by Power Africa have decent natural gas resources. But there is a cost to using these domestically: foregone export revenues. (And there’s a cost to producing them, namely the labor and capital – probably imported in the latter case – that’s required.) It’s not much use to build gas-fired generating capacity unless there’s affordable fuel for it to use (just ask Indian planners). At a minimum, then, you’d need to argue that consumers will be able to pay for the continued operation of OPIC-backed gas-fired power plants. To be more complete you’d need to look at the full cost of gas-fired generation in any comparison – including foregone investment or revenues resulting from more domestic gas use. There is, however, a third thing that weighs strongly toward Moss and Leo’s bottom line: not all megawatts are created equal. A megawatt of wind or solar doesn’t deliver nearly as much electricity over time as a megawatt of gas-fired capacity can. Assuming that fuel is available at an affordable price – a significant assumption that we’ve just looked at – the 42,000 MW of gas-fired capacity that Moss and Leo estimate are actually more than 10 times as valuable as the 4,200 MW of renewables they flag. What’s the bottom line here? Moss and Leo are right to warn us against shortchanging the poor by being dogmatically opposed to supporting fossil fuel development. But it’s far from obvious that directing OPIC money toward natural gas projects consistently yields bigger energy access payoffs than spending it on zero-carbon electricity. Better to pursue a project-by-project assessment of costs and benefits that focuses on the actual impact of each OPIC intervention, not on associating OPIC with the largest volume of private activity, or on insisting dogmatically that it stay out of almost all fossil fuels.

The Most Important Part of the Keystone XL Environmental Impact Statement
The State Department has released its long-awaited final environmental impact statement (EIS) for the Keystone XL pipeline. The headline is straightforward: the pipeline is “unlikely to significantly impact the rate of extraction in the oil sands” and, as a result, world greenhouse gas emissions. This is essentially a status quo conclusion, reaffirming the essence of the draft EIS (released last year). It also allows President Obama to judge that the pipeline meets his requirement that the project “not significantly exacerbate the problem of climate pollution”. The report does, however, carve out one substantial exception. That’s worth drilling down into, because it’s what the President will likely lean on if he decides to say no. The logic in the final EIS (as in the draft) is straightforward: blocking the Keystone XL pipeline is unlikely to significantly affect oil sands production because oil sands has other ways of getting to markets. But the final EIS, unlike the draft one, stress tests that claim, pushing it to identify conditions under which it would fail. It finds some, but they’re narrow. The first condition for Keystone to have a significant impact on oil sands extraction has to do with other pipelines: they need to consistently fail for Keystone to matter. Otherwise, denial of Keystone would shift oil sands to different routes that have similar economics, with roughly the same emissions results as Keystone itself. The second condition has to do with rail. If no pipelines are built, oil sands will be shipped by rail instead, with producers incurring higher transport costs as a result. The draft EIS noted this, but argued that oil prices were so high relative to the breakeven price for new oil sands investment that producers would essentially eat the extra transport costs without cutting production. Producers’ profits would drop, but extraction would remain the same, as would emissions. The final EIS leans on this with a simple question: is there any oil price at which this argument would fail? Its answer is yes – which is at the heart of the exception that the EIS carves out. At an oil price between $65 and $75, it says, the extra cost of transporting oil by rail rather than pipeline would flip some producers’ economics from the black into the red, prompting them to leave some Alberta oil in the ground. (Below $65, the rail versus pipeline distinction would again be mostly moot, since oil sands extraction would quickly become uneconomic in general.) Here’s what the EIS says: “Assuming prices fell in this range, higher transportation costs could have a substantial impact on oil sands production levels—possibly in excess of the capacity of the proposed Project—because many in situ projects are estimated to break even around these levels. Prices below this range would challenge the supply costs of many projects, regardless of pipeline constraints, but higher transport costs could further curtail production.” The EIS authors note that a $65-$75 oil price is below most long-run estimates. As a result they treat this possibility as an outlier. My guess is that their worst-case scenario is even less likely than they think. Why? Because it’s difficult to conjure a low oil price case in which oil sands production is sharply constrained. To the extent that some forecasters expect oil prices to fall and stay below $75, it’s because they see a surge of non-OPEC oil supplies combining with low demand to push prices down. A significant contributor to that surge, of course, is new output from the Canadian oil sands. The upshot is that if forecasters were asked for projections in which oil sands were trapped in Alberta, even fewer would project oil prices below $75 than do today. Here’s another way to look at this. Imagine that oil prices go down to $70 because of a mix of supply gains and demand curbs -- the sort of scenario the EIS flags. And now imagine that, because of constrained transportation options, the average break-even cost of a new oil sands development suddenly rises from $65 to $75, blocking some oil sands investment. What happens to oil prices? They go up, either to squeeze demand or to boost supplies, in order to make up for the missing Canadian oil. Those higher prices, in turn, weigh against the higher transport costs, bringing some Canadian projects back into the black. Among other things, this makes it difficult to believe the EIS claim that blocking oil sands pipelines could ultimately have an impact “possibly in excess of the capacity of the proposed Project”. There are self-correcting mechanisms – less oil production in one place means higher oil prices everywhere and consequently more oil output somewhere else – that would weigh strongly against this. To be certain, even if blocking the pipeline were to keep Canadian oil in the ground, that wouldn’t make killing Keystone a good idea. Just because there could be climate impacts from the pipeline (and, to be clear, I think there would be some small ones) doesn’t mean that they would be large. More important, any decision on the pipeline will need to go well beyond climate and take economics and international relations into central consideration as well. If the President decides to reject Keystone, though, it will be on climate grounds. And the final EIS shows that, if he wants to do that, he’ll need to thread a very small needle.

Energy Independence Won’t Slash the Trade Deficit: Study
Most things about the U.S. oil and gas boom are controversial, but one consequence seems pretty widely agreed: as the United States cuts its oil imports, its trade deficit will fall, solidifying the country’s position in the world. But in a study published today by the Council on Foreign Relations (CFR) project on energy and national security, Robert Lawrence argues that the conventional wisdom is wrong. In the long run, he argues, falling U.S. oil imports will spur developments elsewhere in the economy that will offset their impact on the trade deficit. The net result, he concludes, is that the trade deficit will be little changed. Short-run dynamics, though, can be different, which is a big part of why several serious modeling efforts have projected a falling trade deficit as a result of reduced oil imports. One of the particularly enlightening parts of the Lawrence paper is its unpacking of the short run dynamics. (I should note that as with all CFR publications, all the conclusions are those of the author, not of CFR or any part of it.) Different analysts can come to very different conclusions about the trade deficit depending on their assumptions about some basic economic parameters, such as the multiplier effect of increased investment – and the paper shows how particular assumptions influence analysts’ ultimate results. Check out the whole paper here. And don’t hesitate to discuss the study in the comments.

    Is Europe’s Renewables Mandate Bad for the Environment?
    Rob Stavins has a provocative post up at his (excellent) blog arguing that European renewables mandates are bad for the environment. Much of it makes good sense – but I suspect that it goes too far. Stavins’s logic is simple. Since European stationary-source emissions are capped under the EU ETS, any renewables mandate simply shifts emissions around, rather than reducing them. And because carbon prices will be lower in the presence of a renewables mandate, less low-carbon innovation will be induced when a renewables mandate exists. (High carbon prices provoke investment in low-carbon innovation.) The net result is that adding a renewables mandate to a cap and trade system is bad not only for the economy but for the environment too. Most of Stavins’s argument is persuasive – it is, among other things, a useful antidote to the oddly emphatic claim on the New York Times editorial page that Europe’s “ambitious [emissions] goals will not be met without continued incentives for renewable energy”. But his final judgment seems to have three potential holes. The first hole has to do with technological change. Yes, as Stavins writes, lower carbon prices mean less incentive from a carbon price for low-carbon innovation. But the renewables mandate, depending on how it’s structured, means more incentive for renewables innovation! It’s going to be immensely difficult to determine how this one nets out. But it doesn’t make sense to pay attention only to the lower carbon price and not to the stronger renewables incentives when making a net assessment. The second hole has to do with international spillovers. I can think of two relevant mechanisms. First, higher domestic carbon prices raise demand for international carbon offsets. A corollary is that, with higher carbon prices, a larger fraction of a system’s mandated emissions cuts will come from outside. To the extent that international offsets are less credible than domestic emissions cuts, a higher carbon price for a given cap means higher global emissions. Second, and perhaps most important, by altering the incidence of carbon abatement costs, renewables incentives should influence international carbon leakage. To see how this works, it’s useful to set renewables aside for a moment and think about complementary abatement policies in general. Imagine that one imposed a policy that forced all of the costs of the emissions cuts that Europe seeks to come only from sectors that can’t relocate. Then the carbon price would drop to zero – including in sectors that potentially could relocate. In this scenario, there should be no carbon leakage – which is less leakage than one would expect given a carbon price. Now imagine a scenario at the other extreme: the burden of emissions cuts is imposed entirely on sectors that could potentially relocate. These sectors now face much higher costs, and are more likely to relocate than they would have been under a simple carbon price. Emissions leakage is now higher than under a simple carbon price. Now let’s get back to renewables: Which of these extremes is a renewables incentive closer to? It depends on the structure of the incentive. Some renewables incentives (such as broad-based feed-in tariffs) push electricity prices up even more than a carbon price does (for a given emissions reduction); if these increases are normally passed on to trade-exposed industries, they can increase carbon leakage and worsen environmental outcomes. Other renewables incentives (such as renewables subsidies paid for from the general budget) push electricity prices down, and hence should reduce carbon leakage (though a thorough analysis should include the effects of any second-order impacts on tax or interest rates too). Either way, if one wants to know the ultimate environmental impact of renewables incentives when combined with cap-and-trade, one needs to reckon with international leakage. The last potential hole in Stavins’s argument is politics. Higher carbon prices presumably lead to greater political pushback against carbon pricing. In that case, if renewables mandates lower the carbon price for a given cap, they can make that cap more likely to stick, ultimately keeping emissions lower than they otherwise would be. To be fair, though, an astute commenter on Stavins’s blog makes a smart counterargument: the way that Europe has implemented its renewables incentives has raised electricity prices more than a straight carbon price would have, in the process provoking plenty of pushback against climate policy in general. It’s possible to imagine, then, that pairing renewables incentives with carbon pricing could undermine support for both. Ultimately, it’s tough to know what political dynamics ultimately mean for the net impact of a renewables mandate on European emissions. Bottom line? Stavins is right that combining environmental policies can result in odd, and possibly perverse, environmental outcomes. Whether that’s the case for Europe’s renewables policies, though, is more complicated than meets the eye.

    Is Solar Really “Cost-Competitive” with Fossil Fuels?
    A finding last week by a Minnesota judge that a proposed solar project is a better way to meet the state’s electricity demand than several competing natural gas facilities has been making news. The decision has been reported as a “landmark” declaration that solar is “cost-competitive” with fossil fuels. It seems that few of those who have been reporting on the ruling have actually read it. A deeper dive reveals that solar got the nod because of state policy rather than superior standalone economics. It also points to some tricky decisions ahead for regulators. The 48-page opinion is long and complicated but can be summarized pretty straightforwardly. Several developers submitted proposals for meeting incremental electricity demand. A consultant to the government conducted a series of modeling exercises, which all concluded that various proposed gas plants were the most economic ways to meet Minnesota’s electricity needs. The judge pointed out, though, that Minnesota will need to add a substantial amount of solar in the coming years to meet a statutory mandate for solar power. He also argued that the state will need less incremental electricity than some others have claimed. Once that mandated solar power is added, he claimed, the state will need very little additional electricity generation. Hence the proposed gas plants would likely be superfluous, making them almost entirely a waste of money. The solar proposal, at least, would meet the mandate. On top of that, the judge cited an expert analysis as determining that solar would deliver the lowest levelized cost of electricity (LCOE). But that expert analysis appears to incorporate revenues from sales of renewable energy certificates (RECs) by the solar project in determining its net cost. (I write "appears" because I can’t track down the analysis; I’ve only read filings that refer to it.) Those RECs, of course, only exist because of the mandate. None of this means that the judge made the wrong decision or that the supportive policies are bad. (I don’t know enough about this case or the details of electricity modeling and regulation to have a view on that.) It does mean, however, that it’s wrong to take this as evidence that solar is cost-competitive absent policy support. Policy support (beyond the federal investment tax credit) was central for the judge’s findings. This episode also suggests a quirk that needs to be grappled with. The judge’s logic around the state solar mandate seems to have essentially disqualified all the non-solar competition. Ultimately, then, this “competitive” bidding process seems to not have really been competitive, with only one viable project considered. Perhaps the judge is correct that solar is the only way to go – but, in that case, Minnesota consumers presumably should get to play some competing solar bids against each other. As mandates become increasingly important in shaping the country’s electricity system, predictably and transparently integrating them with the utility sector’s peculiar mix of regulation and competition will be of paramount importance.
