“Modern” renewable energy sources made large gains in providing for global energy consumption over the ten years from 2009-19, according to a recent report, but that “headline” is highly misleading. So is a separate report on the costs of solar and wind power, which claims those sources are now cheaper than any fossil fuel. The underlying facts will receive little critical examination by a hopelessly naive press, nor among analysts with more technical wherewithal. Of course, “green” activists will go on using misinformation like this to have their way with policy makers.

Extinguishing Dung Fires

The “Renewables Global Status Report” was published in mid-June by an organization called REN21: Renewables Now. Francis Menton has a good discussion of the report on his blog, The Manhattan Contrarian. The big finding is a large increase in the global use of “modern” renewable energy sources, from 8.7% of total consumption in 2009 to 11.2% in 2019. The “modern” qualifier is critical: it distinguishes renewables that made gains from those that might be considered antiquated, like dung chips, the burning of which is an energy staple in many underdeveloped parts of the world. In fact, the share of those “non-modern renewables” declined from 11.0% to 8.7%, almost fully accounting for the displacement caused by “modern renewables”. The share of fossil fuels was almost unchanged, down from 80.3% in 2009 to 80.2% in 2019. Whatever the benefits of wind, solar, and other modern green power sources, they did not make much headway in displacing reliable fossil fuel energy.

I certainly can’t argue that replacing dung power with wind, solar, or hydro is a bad thing (but there are more sophisticated ways of converting dung to energy than open flame). However, I contend that replacing open dung fires with fossil-fuel or nuclear capacity would be better than renewables from both a cost and an environmental perspective. Be that as it may, the adoption of “modern renewables” over the ten-year period was not at the expense of fossil fuels, as might be expected if the latter was at a cost disadvantage, and remember that renewables were already given an edge via intense government efforts to subsidize and even require the use of wind and solar power.

The near-term limits on our ability to substitute renewables for fossil fuels should be fairly obvious. For one thing, renewable power is intermittent, so it cannot be relied upon for baseload generation. The chart at the top of this post demonstrates this reality, though the chart is “optimistic” in the sense that planners have to consider worst-case intermittency, not merely average production by time-of-day. Reliable power sources must be maintained in order to prevent the kinds of disasters like we saw in Texas last winter when demand spiked and output from renewables plunged. This is an area of considerable denialism: a search on “intermittent renewables” gets you an unending list of rosy assessments of energy storage technologies, and very little realistic commentary on today’s needs for meeting base-load or weather-induced demands.

While renewables account for about 29% of global electricity generation, there is another limit on adoption: certain jobs just can’t be done with renewables short of major advances in battery technology. As Menton says:

“Steel mills and tractor trailer trucks and airplanes powered by solar panels? Not happening. … I think these people really believe that if governments will just do the right thing and require airplanes to run on solar panels, then it will promptly happen.”

Cost and Intermittency

Again, we’d expect to see more rapid conversion to renewable energy, at least in compatible applications, as the cost of renewables drops relative to fossil fuels. And major components of their costs have indeed dropped, so much so that the U.S. Energy Information Administration (EIA) now says they are cheaper than fossil fuels in terms of the “levelized cost” of new electric generating capacity. That’s the average cost per megawatt-hour produced over the life of a new installation. The EIA’s calculations are distorted on at least two counts, however, as Willis Eschenbach ably explains here.

The EIA’s cost figures reflect a “capacity factor” that adjusts the megawatts produced to presumed “real world” conditions. It’s more like a utilization adjustment made necessary by a variety of realities (intermittency as well as other technical imperfections) that cause output to run lower than the maximum under ideal conditions. Eschenbach reports that the factors applied by the EIA for solar and wind, at 30% and 41%, respectively, are overstated drastically, which reduces their cost estimates by overstating output. For solar, he cites a more realistic value of 14%, which would more than double the levelized cost of solar. For wind, he quotes a figure of 30%, which would increase the cost of wind power by more than a third. That puts the cost of those renewables well above that of a “combined-cycle gas” plant, which uses exhaust from gas turbines to generate additional power via steam.

The true costs of renewables are likely much higher than nuclear power as well, based on earlier comparisons of nuclear to combined-cycle gas. The EIA does not report a cost for nuclear power, however, because the report is for new capacity, and no additions of nuclear capacity are expected.

The Cost of Back-Up Capacity

Eschenbach notes a second major problem with the EIA cost comparisons. As discussed above, the intermittency of solar and wind power means that their deployment cannot provide for base loads. Other “dispatchable” power technologies, on which production can be ramped up or down at discretion, must be available to meet power needs when renewables are off-line, as is frequently the case. The more we attempt to rely on renewables, the more significant the intermittency problem becomes, as Germany, Texas, and California are discovering.

How to account for the extra cost of dispatchable power required to smooth production or meet peak demand? Renewables are simply incapable of doing so reliably, and back-up capacity ain’t free! Meeting demand at all times requires equivalent dispatchable capacity in the power mix. It requires not just dispatchable baseload capacity, but surge capacity! Meeting long-term growth in demand with renewables implies that new back-up capacity is required as well, and the levelized cost should reflect it. After all, those costs won’t be saved by virtue of adding renewable capacity, unless you plan on blackouts. Thus, the EIA’s levelized cost comparisons of wind, solar and fossil fuel electricity generation are completely phony.

Conclusion

Growth in wind and solar power increased their contribution to global energy needs to more than 11% in 2019, but their gains over the previous ten years came largely at the expense of more “primitive” renewable energy sources, not fossil fuels. And despite impressive declines in the installation costs of wind and solar power, and despite low variable costs, the economics of power generation still favors fossil fuels rather substantially. In popular discussions, this point is often obscured by the heavy subsidies granted to renewables. 

In truth, the “name-plate” capacities of wind and solar installations far exceed typical output, so installation costs are spread over less output than is widely believed. Furthermore, the intermittency of production from these renewable sources means that back-up capacity is still required, almost always from plants fired by fossil fuels. Properly considered, this represents a significant incremental cost of renewable power sources, but it is one that is routinely ignored by environmentalists and even in official reports. It’s also worth noting that “modern” renewables carry significant external costs to the environment both during the useful life of plant and at disposal (and see here). It’s tempting to say all these distortions and omissions are deliberate contributions to the propaganda in favor of government mandates for renewables.

When Government Externalizes Internalities

The headline describes a kind of government failure. In an ideal private transaction, costs and benefits are fully internalized by the buyer and seller. Both reap private gains, or surplus, from mutually beneficial transactions. On the other hand, there are cases in which external costs are inflicted on otherwise unrelated third parties, as when production emits pollutants. Or, there might be external benefits that inure to third parties, as when a homeowner pays to beautify their property and the whole neighborhood gains. These “externalities” are commonly citied as rationale for government interference in private markets. A good government, it is said, would seek to “internalize the externalities”, in one way or another, to prevent too much trade in a good imposing external costs, or too little trade where there are external benefits. Imposing taxes, granting subsidies, intervening with price controls, quotas, or various regulations are all ways in which corrective action might be attempted by public authorities.

The problem is that government often chooses badly, both misidentifying externalities, poorly estimating their magnitude, or in choosing how best to address them. When mistakes of this nature occur, the internal gains from trade are not just compromised or even destroyed. They are often externalized — revoked and redistributed to non-participants. The formerly private and internal gains may be extracted in the form of taxes, ultimately flowing to unconnected third parties. They are externalized internalizes, if I may coin a phrase. In other cases, in order to subsidize favored industries, individuals might be taxed on their income. Yet the favored industry is likely  unconnected or external to the taxed individual’s source of income. While the gains that might accrue in the favored industry are internalized there, their source is an externalized internality.

Putting the troubling issue of takings or confiscation aside, these mistaken interventions distort relative prices and production decisions, with false signals propagating into other markets — which again are external effects. This, in turn, distorts the allocation of resources across various uses. These cases are clear-cut examples of externalized internalities.

I will confine this discussion to economic matters. By “internalities“, I mean all things within the economic realm that are private and/or reserved to the individual by natural rights. That includes private property and the individual’s freedom to trade and contract with others.

Wrongly taxing presumed “bads” or wrongly subsidizing presumed “goods” are absolute cases of externalizing internalities. And taxing a “bad” excessively (at more than its true social cost) or subsidizing a “good” excessively (at more than its true social benefit) are cases of externalizing internalities. The political temptation to subsidize might be the greater danger, as it is all too easy for public officials and politicians to identify and sell “deserving” causes, especially if they intimate that others will pay.

For example, subsidized education, which primarily benefits private individuals, is billed to the taxpaying public. It over-allocates resources to education, including students with greater value as human resources in other pursuits. Subsidized energy pays the seller of a power source more than its value to buyers, courtesy of taxpayers, and over allocates resources to those energy sources relative to non-subsidized energy and other goods.

Even if an industry is taxed in exact accordance with its true social cost, there is still the question of how the proceeds of the tax are to be distributed. Ideally, unless the social costs are borne equally by all, the distribution should bear some proportionality to the damages borne by individuals, yet that is seldom considered outside of certain kinds of litigation. The true victims will almost certainly be shorted. Benefits will accrue to many who are free of any burden inflicted by the undesired activity. The corrective action thus fails to properly address the externality, and it bestows an incidental external benefit on wholly unconnected parties.

Likewise, subsidies paid to an industry in exact accordance with its true social benefits require taxes that may burden individuals who do not stand to benefit from the subsidized activity in any way. That is true unless the industry in question produces a pure public good. Indeed, if the taxed individuals had a choice in the matter, they would often use the funds for something they value more highly. Thus, suboptimal distribution of the tax proceeds for funding a less-than-pure “social good” involves the extraction of an internality.

Other forms of government action have similar externalization of internal costs or benefits. With the imposition of a wage floor, or minimum wage, the least-skilled workers are likely to lose their jobs. Consumers are likely to pay higher prices as well. The job losers become more dependent on public aid, which must be funded via taxes on others. The wage floor will also degrade working conditions for those lucky enough to keep their jobs. All of these effects of market intervention demonstrate the public piercing of internal gains from private, voluntary trade. Some of what is excised gets spilt, and some gets siphoned off to external parties. Thus internalities are externalized.

Regulation of private industry often results in regulatory capture, whereby regulators impose rules with compliance costs too high for small competitors and potential entrants to afford. This obviously strengthens the market power of larger incumbents, who may in turn increase prices or skimp on quality. Taxpayers pay the regulators, consumers pay the inflated prices, smaller firms shut down, and resources are under-allocated to the product or service in question. These distortions spill into other markets as well. All these effects are part of the despoilment of internal gains from trade. To the extent that trades are prevented at competitive prices, the external winners are those who capture trades at higher prices, along with the regulators themselves and anyone else standing to benefit from graft as part of the arrangement. And again, the wrongful gains to the winners can be described as externalized internalities.

There are many other examples of government failure that fit the description of externalized internalities. In fact, extracting internalities is the very essence of taxation, though we readily accept its use for expenditures on goods that are of a truly public nature, which by definition confer benefits that are non-exclusive. The classic case, of course, is national defense. The differences in the cases of government failure cited above, however, are that the internalities extracted via taxation or other forms of intervention are externalized for private gain by other parties, no matter how widely distributed and diffuse. This is an extremely pernicious kind of government failure, as it ultimately leads to a cannibalization of private activity via our role as public actors. Beware politicians bearing gifts, and beware them just as much when they demonize private trade.

“Recycling Is Largely Fake”

The quotation headlined above is from Duke University economist Michael Munger, and it’s essentially what I’ve contended for years (see “When Is Recycling Not Wasteful?“). Munger’s latest essay on this subject is entitled, “For Most Things, Recycling Harms the Environment“. The reasons are very basic: resource costs. As Munger says, the degree of economic and environmental justification for recycling varies, depending on the item, but few supporters of recycling ever bother to look into the details.

First, a very basic economic point: resource conservation is beneficial for the environment. Sometimes there are technological trade-offs between conservation of different resources, but costs are always a matter of resource use: less use, lower total costs. Resource conservation is synonymous with lower costs. Indeed, that is why we are told to recycle, and that is what most people think they’re doing when they recycle.

But while recycling always conserves some resource more or less directly, the mere process of recycling uses other resources. This includes the costs of rolling trucks to collect the items, including fuel, labor, machinery and labor for sorting, water, chemicals, more distant shipping, and separate processes to convert the items into usable goods. In its entirety, then, recycling often does not conserve resources.

Voluntary consumer-recyclers seldom face the marginal costs of recycling directly. This highlights the general nature of environmental problems that arise in any society: external costs are often borne by parties external to the activity in question. And here is where the story of recycling’s poor economics gets interesting. Recycling advocates would have us believe that our private use of products, for which we generally pay full cost, imposes external or social costs on others unless we recycle all recyclable components of the product and it’s packaging. In fact, the opposite is often true!

Therefore, governments, fully on-board with popular recycling myths, often mandate recycling, which is another way of saying that you are not free to make your own decision based on costs and benefits. So the costs of recycling are on you, but you are unimpacted at any margin along which you can make decisions. You are forced to internalize some part of the costs that are presumptively avoided via recycling according to the myth. You pay taxes to fund the collection of materials at the curb, but governments often require citizens to clean and sort those materials. That carries significant costs that governments prefer to remain implicit.

This is to say nothing of the actual net value of the recycled materials, which is often negative. Certain items require so much processing and produce materials of such low quality that no one wants them. Virgin materials are often cheaper than fully processed recycled material, and usually yield better quality, or both. Far better, then, to pay the cost of transporting these kinds of discards to landfills and paying for the low-cost landfill space, which is plentiful, contrary to greenist propaganda.

Munger provides examples of such wasteful-to-recycle materials. For instance, attempts to recycle glass bottles are often completely non-productive relative to landfilling. That’s due to cost factors, lousy quality after processing, and weak market prices for recycled glass. Plastics are of questionable value as recyclables as well: huge quantities had been shipped to the Far East, but the volume was too much for the Chinese (and too dirty, they claimed), so it often ended-up in landfills anyway. Last year, the Chinese banned imports of recyclable plastics from several countries, which means that our plastic materials are probably headed for our own landfills. Yet we still go to the trouble of preparing and collecting them for recycling.

According to Munger, aluminum cans are worthwhile to recycle relative to landfilling. So are certain types of cardboard (though the Chinese don’t want some of those either). Also, scrap metals are privately recycled via active markets for the materials.

Private parties who can internalize costs in their voluntary decisions are wise to abide by the following:

“I have sometimes suggested a test for whether something is garbage or a valuable commodity. Hold it in your hand, or hold a cup of it, or tank, or however you can handle it. Consider: Will someone pay me for this? If the answer is yes, it’s a commodity, a valuable resource. If the answer is no, meaning you have to pay them to take it, then it’s garbage.”

Of course, society as a whole must internalize costs. There’s no way around it. Therefore, governments should behave as if they internalize costs as well, though they hardly ever do. They would sooner mandate recycling when they know full well that the simple economics outlined above don’t support it. That means an unnecessary consumption of resources is attributable to the recycling charade, which is environmentally unsound by the strictest of Green standards.

I am not quite so hard on government recycling mandates when there exist significant external costs associated with sending uneconomic trash to landfills, or when there are real efficiencies associated with recycling. Landfills must price their space efficiently, collecting sufficient fees from users to pay for environmental mitigation as well as the payoffs necessary to mollify those nearby who might happen to harbor NIMBY-ism. But recycling mandates offer strong evidence that the economics of recycling are not worthwhile. So please, whenever you are told that recycling is virtuous, be suspicious. As Munger says, it’s largely a fraud.
