Adam Tooze unpacks a recent report from the clean energy think tank Ember— one that heralded a profoundly important historical turning point…

Electrification is key to the new energy system that is being built around the world. Electricity generation is one process we do know how to decarbonize. With concerted action, net neutrality is within reach in electric power generation for OECD countries by the 2030s and for the whole world by 2045. Furthermore, as Ember points out, electrification will replace “fossil fuel burning that currently takes place in car and bus engines, boilers, furnaces and other applications.”

Green electrification is the key to the future. And in 2023, according to Ember’s report, almost the entirety of new power demand was covered by growth in renewables, above all solar. Though there was growth in demand for electricity around the world, fossil fuel generation barely increased. Growth in solar and wind alone were sufficient to cover 82 percent of new electricity demand.

This is not new in rich countries. In the OECD demand growth for electricity is not strong or is even negative and renewable investment has been ongoing for two decades. The sensation is that this is now happening at the global level where the growth in demand for electric power is relentless.

In 2024 Ember expects the trend to be even more pronounced. This year, for the first time there will be substantial growth in global demand for electricity, whilst fossil fuel generation will likely fall…

… There is an obfuscation involved in talking about “the global” when, in fact, there is one country that dominates the entire dynamic of the energy transition: China.

As Ember’s data show: “China remained the main engine of global electricity demand growth. China’s rapid growth (+606 TWh, +6.9%) was just 21 TWh lower than the net global increase. India’s growth (+99 TWh, +5.4%) was the next largest contributor.”

Until the 2010s China fed its voracious demand for new power with coal-fired power stations. The energy transition in the advanced economies was never going to be sufficient to offset this. Of course, the renewable energy transition in the West was also painfully slow. But even if the USA and the EU had taken more drastic action, China’s growth was simply too large and too dirty. The fact that we are now reaching a turning point in the balance between fossil and clean power generation is due to a turning point in China: a huge surge in renewable energy investment.

In 2023 China alone accounted for more than half of the new global additions in wind and solar…

Measured in terms of power consumed China’s electrification of road transport is 3.5 times larger than that of the entire rest of the world. That is the EV revolution that the West is so worried about….

It is also the largest heat pump market in the world with more installations per year than any other country. Electrolysers, used mostly in demonstration plants by chemical and petrochemical companies, have also grown faster in China than the rest of the world. As a result, China accounted for 50% of global electrolyser capacity in 2023…

But as Ember notes, this process of applying electricity to new uses, is only at the beginning.

Even in China, electrification is still in its infancy. Only a fifth of China’s electricity demand growth in 2023 (124 TWh of 606 TWh) was from the three electrification technologies, but this share will rise in time. These technologies added 1.4% to China’s electricity demand in 2023, up from 1.1% in 2022. Meanwhile in the rest of the world, electrification added 0.25% to electricity demand in 2022 and 0.28% in 2023. As China further accelerates the deployment of key electrification technologies and the world continues to catch up, the contribution of electrification will expand even further.

At COP28 in 2023 many countries around the world committed to tripling global renewable electricity capacity by 2030. This has the potential to almost halve power sector emissions by 2030, as coal-fired power generation will be replaced first. Furthermore, it will provide enough new electricity to replace drive forward the electrification of transport, home and industrial heating with a 32 percent increase in electricity demand.

Having shattered all previous experience of renewable power rollout, China’s huge surge in solar now actually puts us within striking distance of achieving a net zero path, driven by green electric power…

What we are witnessing is the most rapid take-up of a significant energy technology in history.

The response of Western politicians? Protectionism. Of course there are complex motives. They need to build coalitions to sustain the energy transition. They are worried about the CCP regime in China. They want to escape extreme dependence on imported sources of energy (though of course in the renewable space it is capital equipment not energy they are importing). But the more basic question is simply this. Are Western government and societies willing to prioritize the energy transition if it is not their drama, not their success story? Or, if the PV panels and the electric vehicles are from China, do other interests take priority?

In the European case one can see a compromise based on a balance between domestic and Chinese-sourced energy transition solutions. As Martin Sandbu has remarked there is at least the possibility of a grand bargain. In the case of the United States it seems increasingly clear that the energy transition as such is a second order concern, and geopolitical confrontation and the struggle to form domestic coalitions take precedence. That is depressing. And it matters. But, as Ember’s data make clear, it is far from being a decisive obstacle. The global energy transition will go on anyway…

As we find solace where we can, we might spare a thought for Joseph Wood Krutch; he died on this date in 1970. An author, critic, and naturalist, he began his career in New York City, where he was a professor at Columbia and theater critic for The Nation, and where he wrote The Modern Temper (challenging the then-fashionable notions of scientific progress and optimism), biographies of Samuel Johnson and Henry David Thoreau, and (inspired by Thoreau) The Twelve Seasons, Krutch’s first nature book.

In 1952, on doctor’s orders, Krutch left the East for Tucson and the Sonoran Desert, where he began writing about ecology, the southwestern desert environment, and the natural history of the Grand Canyon. He won renown as a naturalist, nature writer, and an early conservationist for works like The Voice of the Desert and The Desert Year, arguing that human beings must move beyond purely human centered conceptions of “conservation” and learn to value nature for its own sake.

As we adjust our necklaces of garlic, we might spare a memorial thought for Hugo Gernsback, a Luxemborgian-American inventor, broadcast pioneer, writer, and publisher; he died on this date in 1967 at the age of 83.

Gernsback held 80 patents at the time of his death; he founded radio station WRNY, was involved in the first television broadcasts and is considered a pioneer in amateur radio.  But it was a writer and publisher that he probably left his most lasting mark:  In 1926, as owner/publisher of the magazine Modern Electrics, he filled a blank spot in his publication by dashing off the first chapter of a series called “Ralph 124C 41+.” The twelve installments of “Ralph” were filled with inventions unknown in 1926, including “television” (Gernsback is credited with introducing the word), fluorescent lighting, juke boxes, solar energy, television, microfilm, vending machines, and the device we now call radar.

The “Ralph” series was an astounding success with readers; and later that year Gernsback founded the first magazine devoted to science fiction, Amazing Stories.  Believing that the perfect sci-fi story is “75 percent literature interwoven with 25 percent science,” he coined the term “science fiction.”

Gernsback was a “careful” businessman, who was tight with the fees that he paid his writers– so tight that H. P. Lovecraft and Clark Ashton Smith referred to him as “Hugo the Rat.”

Still, his contributions to the genre as publisher were so significant that, along with H.G. Wells and Jules Verne, he is sometimes called “The Father of Science Fiction”; in his honor, the annual Science Fiction Achievement awards are called the “Hugos.”

(Coincidentally, today is also the birthday– in 1906– of Philo T. Farnsworth, the man who actually did invent television… and was thus the inspiration for the name “Philco.”)
