The challenges of going green.

Decarboniz­ing the air and economy will take a lot of ambition, innovation and a few breakthrou­ghs

Decarboniz­ing the state’s air and economy won’t be easy or cheap. It will take ambition, innovation and breakthrou­ghs. »1D

As Colorado officials begin their quest to decarboniz­e the economy at a record pace, in line with a number of new laws passed by the legislatur­e, they could do worse than pause to consider the lessons from Germany’s recent past.

In a lengthy report published this month by Der Spiegel, reporters recounted how Germany’s much-hyped transition to renewable energy (abandoning nuclear along the way) had bogged down and was facing failure.

Not only has Germany fallen short of targets for reducing greenhouse gases, Der Spiegel noted

(it has an English edition), but “German CO2 emissions have only slightly decreased this decade.” Green energy projects face lawsuits and local opposition, while progress on decarboniz­ing other sectors of the economy hardly registers at all.

And the price of electricit­y? The highest in Europe.

Perhaps the biggest lesson for Colorado officials: Don’t set yourselves up for failure with extravagan­t promises. Don’t convey the impression that radical reductions of greenhouse gases are easy or cost-free, especially since much of the public seems to believe that success is merely a matter of erecting more wind turbines and solar panels.

Those technologi­es directly address only the one-fourth of the national economy’s carbon emissions that come from power plants (the figure is closer to one-third in Colorado). Residentia­l and commercial heating, industrial processes, agricultur­e, transporta­tion and waste management make up the remainder, for which solutions are more complex or altogether elusive.

As Bill Gates, who has invested heavily in

clean-energy technology, wrote last year in his blog, “There’s not a broad awareness of how challengin­g it’s going to be to bring down greenhouse gas emissions.”

House Bill 1261 commits Colorado to pursuing total emission reductions of 50 percent from 2005 levels by 2030 and 90 percent by 2050. Since these are hugely ambitious targets, I sat down recently with the director of the governor’s Energy Office to see what state officials have in mind.

I’ve known Will Toor for years and appreciate his willingnes­s to explain his point of view without resorting to end-of-times environmen­tal rhetoric. Maybe the former Boulder mayor’s scientific background — a PH.D. in physics — helps keep his feet on the ground.

Toor admits the 2030 goal in HB 1261 is “challengin­g,” and the 2050 goal will require technologi­cal breakthrou­ghs. But he believes a “plausible path” exists to 2030 given enough progress mainly on three fronts: electricit­y, transporta­tion and oil and gas production. Specifical­ly, he says, reduce power plant emissions by 80 percent; adopt California’s fuel efficiency standards while requiring automakers to sell nearly 1 million electric vehicles (EVS) here in the next decade; and make “really deep reductions” in methane emissions from drilling to distributi­on.

Are these goals achievable? Maybe. The state’s largest electric utility, Xcel Energy, already touts a company-wide goal of 80 percent clean energy by 2030. And thanks to a new law that allows considerat­ion of the “social cost” of emissions, Xcel will enjoy greater freedom than ever to put the squeeze on ratepayers.

But 80 percent clean energy by 2030 is ambitious even for Xcel; its carbon-free portfolio in Colorado in 2017 was 28 percent, according to its website.

Nor is Xcel the only electricit­y provider. Black Hills Energy serves Pueblo and nearby areas, while a number of municipal utilities and rural electric cooperativ­es operate, too. To take one example, the Colorado Springs utility expects “to reduce our carbon emissions by 40 percent or more from 2005 to 2035,” according to its 2018 environmen­tal report.

Clean electrical power is important to regulators in part because it makes plans for “electrifyi­ng other sectors more attractive,” as Toor puts it. An EV is “clean” only to the extent the electricit­y that charges it is. But here regulators run smack into the bracing chaos of a real marketplac­e: multiple car companies, numerous dealers and millions of consumers with strong preference­s of their own.

The state is considerin­g two approaches. The first is a typical iron-fisted edict — a mandate that a percentage of an automaker’s fleet sold in the state be EVS and grow over time. Alternativ­ely, the state might stipulate that a wide variety of EVS, including SUVS and crossovers, always be available in significan­t numbers on dealer lots and are aggressive­ly marketed.

The second approach is less likely to result in price hikes on traditiona­l vehicles to offset discounts for EVS if consumers fail to embrace them on their own merits.

We will learn a great deal about how determined the Polis administra­tion is to force-feed consumer markets in its pursuit of carbon reduction when it chooses between these options.

Meanwhile, the path toward major progress in other sectors — both in the next decade and beyond — is less clear. Take residentia­l and commercial heating. Should that be electrifie­d, too? The state will study the economics, Toor says. Yet beyond new constructi­on, progress is bound to be slow. Who would pay the colossal bill for retrofitti­ng millions of structures?

How about heavy trucks? An “open question,” Toor suggests, although hydrogen is “super interestin­g.”

Aviation and trains? Never mind. Energy intensive manufactur­ing? Another tough nut. And don’t forget agricultur­e. (“If cattle were a country,” Gates says, “they would rank third in greenhouse gas emissions” after China and the U.S.) Even Green New Deal types are not yet ready to order Americans to give up hamburger.

Last month, the Energy Futures Initiative (EFI)– a think tank formed by former Obama administra­tion Energy Secretary Ernest Moniz — released a report on the prospects for California reaching similarly aggressive carbon targets. As E&E reporter Peter Behr correctly concluded, “The report is a head-on challenge to assumption­s that California can achieve its carbon-reduction goals mainly by increasing wind and solar power and battery storage.”

Instead, the report stresses “innovation must be at the heart of a decarboniz­ation strategy” because “the current cost of many important low- and zerocarbon technologi­es is too high.” It warned that “scalable clean technologi­es are not readily available” for a number of applicatio­ns, such as “high-temperatur­e process heat for industry.” Technology priorities should include “hydrogen production with electrolys­is, advanced nuclear, green cement, and seasonal storage, among others.”

Even squeezing the final 20 percent of carbon from electricit­y production will be impossible without breakthrou­ghs. “Maybe modular nuclear reactors really happen,” Toor suggests.

It’s no exaggerati­on to say that Colorado officials are embarking on a project of unpreceden­ted scope and ambition for this state– one that is “extremely challengin­g” and “technicall­y very difficult,” to quote again from the EFI study. And while Americans possess an unrivaled ability to surmount technical obstacles, that’s only true if bureaucrat­s foster an environmen­t in which innovation and experiment­ation can flourish rather than suffocate in a web of red tape. Central planning got a bad name in the 20th century for a reason.

It’s an “exciting time” for progress on clean energy, Toor observes. Yes, but a perilous time as well.
