\t\t\tThe non-linear transition<\/p>\n
A second narrative of failure comes from Michael Cembalest, chairman of market and investment strategy group at JPMorgan Asset Management. In his 15th annual Eye on the Market Energy Paper<\/a>, he acknowledges some progress on cleaning up the energy system, but decides that \u201cafter $9 trillion spent globally over the last decade on wind, solar, electric vehicles, energy storage, electrified heat and power grids, the renewable transition is still a linear one, slowly advancing at 0.3% to 0.6% per year.\u201d\u00a0<\/p>\n This is a bad miss for a usually excellent analyst. To see why, we can use a very simple model, requiring only a four-line spreadsheet, and explore what happens as clean energy continues to outgrow overall energy demand for a few more decades.\u00a0<\/p>\n Let\u2019s start with the global economy, which has been growing at 3.3% per year since the year 2000. Let\u2019s assume this continues into the future. Next, we assume that the historic 1.3% average annual improvement in demand-side energy efficiency continues too, leaving 2% annual growth in demand for energy. We\u2019ll be using real energy demand, not primary energy, which is really a measure of supply.\u00a0\u00a0<\/p>\n Now let\u2019s assume clean energy, so renewables, nuclear, and the ambient heat used by heat pumps, start at today\u2019s 30% and averages a conservative growth rate of 5% per year over the coming decades, considerably lower than the historic growth rate in renewables over many decades.\u00a0<\/p>\n Finally, we\u2019ll let fossil fuels make up the gap between total energy demand and clean energy provision, as it does in the real world.\u00a0<\/p>\n The first thing our simple model shows is that despite growing faster than energy demand, clean energy is not yet able to meet all the additional demand for energy. But let\u2019s run our growth rates out into the future and see what happens. For the next ten years, fossil fuel use continues to grow, falling as a percentage of energy use, but only from just below 70% to just below 60%. Clean energy continues to struggle to meet additional energy demand until 2035. Boo, failure: growth is linear and slow!\u00a0<\/p>\n However, roll the clock another ten years. By 2045, with clean energy continuing to outgrow energy demand by 3% per year, fossil fuel use drops below where it was in 2025, though only by 8%. By now the global economy is using nearly 50% more energy than today, just as all the models say it will, but sourcing less than half of it from fossil fuels.\u00a0\u00a0<\/p>\n Another decade forward, and by 2055 fossil-fuel use has dropped by 40%, so it is now meeting less than one quarter of energy demand. And by 2065, fossil fuels have been squeezed entirely out of the system.\u00a0<\/p>\n That said, in reality growth in clean energy won\u2019t be 5% every year. It will start higher and then drop away as the sector matures. And there will be a tail of obstinately hard-to-abate fossil-fuel use. However, what the exercise shows is that in any scenario in which clean energy grows faster than energy demand over a number of decades, fossil fuels are squeezed out of the system.\u00a0<\/p>\n It is worth noting that our little model generates a quite different trajectory to the vast bulk of the net-zero literature. It doesn\u2019t deliver the large initial drop in fossil-fuel use \u2013 45% by 2030, or whatever \u2013 that activists want to see, followed by a long tail. Emissions stay higher for longer, but then fall away, delivering an outcome broadly consistent with the 2\u00b0C of warming that lies at the heart of the Paris Agreement (though perhaps needing a little carbon dioxide removal in the second half of the century).\u00a0<\/p>\n Our simple four-line model shows that the failure so far to see dramatic reductions in fossil-fuel use says nothing whatsoever about whether or not we are on a pathway to net zero. All the transition requires is a growth rate in clean energy that remains a few percent above the growth in energy demand for long enough \u2013 an approach which is much more plausible than walking away from our existing energy infrastructure.\u00a0<\/p>\n The non-pragmatic reset<\/p>\n This brings me to Tony Blair\u2019s piece. Two days before UK local elections in April, with Nigel Farage\u2019s hard-right Reform party promising to \u201cmake net zero the new Brexit\u201d, the Tony Blair Institute released a report entitled The Climate Paradox: Why We Need to Reset Action on Climate Change, with a foreword by Tony Blair.\u00a0\u00a0<\/p>\n Now, Blair is spot on in calling for a reset \u2013 I was intending to do exactly that in this column before he beat me to it \u2013 but his proposed solution is pretty much the opposite of pragmatic.\u00a0<\/p>\n Blair opens his foreword to the report by pointing to the \u201cirrationality\u201d of the current debate over climate change, explaining that people are \u201cturning away from the politics of the issue because they believe the proposed solutions are not founded on good policy\u201d. To build a burning platform from which to propose his reset, Blair paints a dramatic picture of the failure of past climate action, repeating many of the talking points of Yergin and Cembalest, falling into the primary energy fallacy, and presenting a set of \u201cinconvenient facts\u201d curated to show the futility of the current pathway.\u00a0\u00a0<\/p>\n However, many of Blair\u2019s \u201cinconvenient facts\u201d are either not facts, or are misconstrued. For instance, he makes much of China last year beginning construction of \u201c95 gigawatts of new coal-fired energy, which is almost as much as the total current energy output from coal of all of Europe put together.\u201d Construction starts are not the same as completions \u2013 the fact is that for each of the past five years China completed construction of 34GW of capacity and retired 2.5GW. A lot but not 95GW.\u00a0\u00a0<\/p>\n And capacity is not \u201cenergy output\u201d The capacity utilization of China\u2019s coal-fired power stations, how much they are really used, had dropped from more than 60% in the year 2000 to just over 50% in 2020. The surge in gas prices coming out of Covid and as Russia invaded Ukraine pushed China back to coal, but if gas prices ease further, we should expect the so-called capacity factors of \u00a0 Chinese coal plants to plummet again, and many older power stations to be shuttered. Indeed, recent data already shows China\u2019s coal use falling over the past 12 months<\/a>.\u00a0<\/p>\n More of Blair\u2019s \u201cfacts\u201d are not facts at all, but forecasts. He says urbanization will continue in developing countries (he doesn\u2019t mention it is coming to an end in China), and that Africa will see a doubling of its population over the next thirty years. I hope energy supply does soar in the Global South in coming decades. What the facts show, however, is that these new economic powers are leapfrogging to a far cleaner energy mix than other regions at the equivalent stage of development. They are investing in renewables, with exponential growth in Chinese solar panel imports, and in gas, not coal.\u00a0\u00a0<\/p>\n However, where Blair\u2019s reset really hits the buffers is in its choice of solutions. Having stated that \u201cnet-zero policies, once seen as the pathway to economic transformation, are increasingly viewed as unaffordable, ineffective, or politically toxic,\u201d he hangs his reset on the world\u2019s most unaffordable, ineffective and politically toxic solutions.\u00a0<\/p>\n The first hint of this is in the picture on the report\u2019s front cover: It\u2019s Climeworks\u2019 Mammoth direct air capture (DAC) plant in Iceland. Whatever the solution to climate change is going to be, it won\u2019t involve anything that costs $1,000 per metric ton of carbon removed, or even the $400 to $600 the company promises by 2030. In fact within a month of the publication of Blair\u2019s call for DAC to be at the heart of his climate reset, it was reported in the Icelandic press<\/a> that Climeworks plants had not even captured enough CO2 to cover emissions released during their construction. Embarrassing.\u00a0<\/p>\n In fact, Blair goes big on all sorts of carbon capture and storage (CCS). \u201cAt present,\u201d he asserts, \u201ccarbon capture is not commercially viable despite being technologically feasible \u2013 but policy, finance and innovation would change this.\u201d Really?\u00a0<\/p>\n What does carbon capture being commercially viable even mean? Clean energy solutions are commercially viable when they are cheaper than their fossil equivalents. However, CCS costs money to build, money to maintain, and money run. Unless you are selling the captured CO2 to extract more oil (in which case your project is a huge self-licking ice cream from a climate perspective), the only revenue is from abating emissions.\u00a0<\/p>\n So CCS can never be \u201ccommercially viable\u201d in the absence of voluntary markets for carbon abatement \u2013 which don\u2019t and won\u2019t exist at anything like climate-saving scale \u2013 or a regulatory framework that prices in the cost of carbon. That means you can forget the Global South, whose emissions growth Blair says he\u2019s most concerned about. Even where there is a carbon price, it is far from clear that \u201cpolicy, finance and innovation\u201d would result in CCS cheaper than the entire gamut of clean energy solutions, especially in the light of the decades of failure of the former, and the decades of rapidly falling cost of the latter.\u00a0\u00a0<\/p>\n We will have to do some CCS. We will need it to capture emissions from industrial processes like cement production and aluminum smelting, to make affordable clean hydrogen (hydrogen from natural gas with CCS will remain cheaper than green hydrogen) and to sequester biogenic carbon to cover sectors where abatement is much more expensive, like aviation. But post-combustion CCS on large gas and coal plants will never be close to \u201ccommercially viable\u201d, so putting CCS at the heart of a climate plan is a huge self-own.\u00a0<\/p>\n The other big technology Blair promotes is nuclear: \u201cThe new generation of small modular reactors [SMRs] offers hope for the renaissance of nuclear power, but it needs integrating into nations\u2019 energy policy.\u201d\u00a0<\/p>\n
