Fifty years after the primary world oil shock in 1973, the world’s power sector is once more going through excessive geopolitical tensions and uncertainty—although this time round, “pressures are coming from a number of areas,” Dr. Fatih Birol, govt director of the Worldwide Vitality Company (IEA) wrote as he launched the most recent World Vitality Outlook (WEO2023).
“Alongside fragile oil markets, the world has seen an acute disaster in pure fuel markets attributable to Russia’s cuts to produce, which had sturdy knock-on results on electrical energy. On the similar time, the world is coping with an acute local weather disaster, with more and more seen results of local weather change induced by way of fossil fuels, together with the record-breaking heatwaves skilled around the globe this 12 months,” Birol wrote. “In the end, what’s required is not only to diversify away from a single power commodity however to alter the power system itself, and to take action whereas sustaining the reasonably priced and safe provision of power companies. The rising impacts of worldwide warming make this all of the extra essential, as an rising quantity of power infrastructure that was constructed for a cooler, calmer local weather is not dependable or resilient sufficient as temperatures rise and climate occasions develop into extra excessive. In brief, we have now to remodel the power system each to stave off much more extreme local weather change and to deal with the local weather change that’s already with us.”
In keeping with the 355-page WEO2023, which the IEA issued in late October, momentum for the “transformation” towards “clear power” has been constructing. The IEA outlined a number of elements which might be poised to reshape the world’s power profile by 2030. Nonetheless, it additionally underscored a number of dangers to anticipated change, comparable to price inflation pressures, provide chain hurdles, crucial mineral availability, and geopolitical tensions. Following are some key tendencies the Paris-based intergovernmental group highlights in its newest annual world outlook.
A Projected Surge in Energy Demand. The WEO2023 explores three major situations: a acknowledged insurance policies state of affairs (STEPS), which assumes at present’s coverage settings will endure; the introduced pledges state of affairs (APS), which assumes all governmental aspirational targets might be achieved; and the net-zero by 2050 (NZE) state of affairs, which maps a pathway to attain a 1.5-degree-Celsius stabilization above pre-industrial ranges in 2100 whereas nurturing common entry to power by 2030. STEPS is notably related to a temperature rise of two.4 levels Celsius in 2100 (with a 50% likelihood), the company says.

1. International electrical energy demand, 2010–2050, and era combine by state of affairs, 2022 and 2050. Electrical energy demand rises over 80% to greater than 150% by 2050 throughout situations and is met more and more by low-emissions sources on the expense of unabated coal and pure fuel, the Worldwide Vitality Company’s (IEA’s) newest World Vitality Outlook suggests.

Whereas the company highlights a number of uncertainties that might have an effect on its state of affairs outcomes, a uniform discovering throughout all three situations is that world electrical energy is ready to extend quickly (Determine 1). Inhabitants and revenue development, together with the electrification of rising numbers of end-users, may set demand hovering by over 80% by 2050 in STEPS (and as much as 150% within the NZE state of affairs). In STEPS, the constructing sector will stay the biggest by way of consumption, pushed by demand for home equipment, area cooling and heating, and water heating. The business sector will comply with it. Electrical autos (EVs) account for about 15% of demand development by means of 2050 in STEPS. The report additionally factors to hydrogen manufacturing by way of electrolysis as a doubtlessly sizeable electrical energy shopper, which is proscribed in STEPS and extra distinguished within the APS and NZE situations.
Renewed Coverage Momentum for Cleaner Electrical energy Provide. Latest power crises have highlighted power safety challenges, prompting a short-lived uptick in coal era. Nonetheless, the IEA stated the crises additionally accelerated clear power transitions within the energy sector. “Latest coverage developments have boosted the prospects for renewables in main markets, together with China, European Union [EU], India, Japan, and United States,” the report notes. “Prospects for nuclear energy have additionally improved in main markets, with assist for lifetime extension of current nuclear reactors in quite a lot of nations together with Japan, Korea, and United States, and assist for brand spanking new reactors in Canada, China, United Kingdom, United States, and several other EU member states.” Coverage developments for pure fuel use within the energy sector, nevertheless, have been “combined.” The EU, South Korea, and Japan have taken efforts to scale back demand and reliance on imports, whereas China “sees a continued position for pure fuel,” it notes.
General, the IEA expects energy era from low-emission sources to speed up, with a “mixed output quadrupling” from 2022 to 2050 in STEPS. Within the APS, it will develop to five.5 instances its present degree, and within the NZE state of affairs, it’s poised to extend sevenfold. Renewable capability, particularly, is slated to develop 2.4-fold in STEPS by 2030, enabling renewable’s share of complete world era to soar from 30% at present (15% of which is hydropower) to 50% by 2030. Nonetheless, that development isn’t sure. Hydropower’s “annual output can differ extensively, and excessive upfront capital prices and limitations on growth of favorable websites constrain additional development prospects,” the IEA steered. “Different renewables—bioenergy, geothermal, concentrating photo voltaic, and marine energy— have an element to play too, however photo voltaic PV and wind are the central applied sciences within the roll-out of renewables to decarbonize power provide sooner. The share of wind and photo voltaic PV is ready to rise from 12% at present to about 30% by 2030. To accommodate their variability, utility-scale battery storage capability will enhance almost 85-fold within the STEPS, rising to greater than 2 TW by 2050, the IEA stated.
Whereas nuclear energy capability may enhance from 417 GW in 2022 to 620 GW in 2050, its share of complete era will fall from about 9% at present to eight% in 2050, the report suggests. Nuclear’s development, notably, will proceed to be led by large-scale reactors and lifelong extensions, regardless that “the event of and rising curiosity in small modular reactors will increase the potential for nuclear energy in the long term,” it says.
A Peak for Fossil Fuels. In distinction, coal—nonetheless the biggest supply of energy on the earth at present with a 36% share of complete era—is slated for a fast decline. By 2030, the IEA steered unabated coal’s share of era may fall beneath 25% within the STEPS. Pure fuel energy’s outlook is as dismal. Whereas pure fuel supplies 22% of worldwide electrical energy—together with essential flexibility and reliability companies—gas-fired era will “peak” earlier than 2030 in all three situations, falling to 11% in 2050. Superior financial system markets are “more and more trying to gas-fired energy crops for flexibility fairly than bulk output as they combine rising shares of photo voltaic PV and wind,” the report notes. “Whereas gas-fired energy rises in absolute phrases in China and different rising market and creating economies past 2030, its share progressively declines.”
“A world peak of fossil fuels doesn’t imply all of the nations of the world, all their fossil fuels, will peak,” Birol underscored throughout a livestream on Oct. 24. “For instance, we see that particularly oil and fuel consumption will enhance in a number of creating and rising nations, whereas they see a pointy decline within the superior economies.”
The IEA was extra optimistic about coal- and gas-fired crops outfitted with carbon seize, utilization, and storage (CCUS), and crops co-fired with hydrogen and ammonia. Whereas the IEA projected “restricted progress” in STEPS, it anticipated the tempo will decide up, rising to greater than 1,500 TWh below APS and a pair of,100 TWh below the NZE state of affairs.
Funding Tendencies Shying from Fossil Fuels. In keeping with Birol, investments will make up a significant component driving the fossil gas decline. In STEPS, world energy sector funding may rise from $1 trillion on common over 2018–2022 to $1.4 trillion by 2030, and it anticipated that degree to proceed by means of 2050. The funding will doubtless go to cleaner power sources and battery storage. “At present, the quantity of funding going to offshore wind is about half the funding going to coal and fuel energy crops—however it’s altering quick,” he famous. “In 2030, we see the quantity of funding going to offshore wind might be thrice greater than cash going to fuel and coal crops.”
The IEA, nevertheless, urged extra grid funding, noting a dire want for grid modernization and enlargement. “Grid funding is vital to attach hundreds of thousands of recent clients and new renewable sources, reinforce transmission and distribution, and modernize and digitalize methods,” the report underscores. The IEA projected complete grid line lengths ought to enhance by about 18% from 2022 to 2030 in STEPS and APS, and by 20% within the NZE state of affairs. Excessive-voltage direct-current (HVDC) initiatives might initially lead that cost. The report notes the introduced HVDC pipeline is ready to result in a rise within the size of HVDC traces by about 45% by 2030. Investments in digitalization, sensible methods, and superior high-power semiconductor applied sciences can even be wanted to enhance the management and stability of electrical energy flows.
Looming Dangers for Vitality, Electrical energy Safety. Regardless of optimistic forecasts and substantial funding, the IEA projected massive decarbonization “ambition gaps” towards web zero. “The biggest single contribution to closing the ambition and the implementation gaps in each the APS and the NZE Situation comes from changing coal-fired energy era with renewable power sources,” the company famous. “In rising market and creating economies, the swap to wash sources of electrical energy makes up 40% of complete emissions reductions between at present and 2030 in each situations.”
Sensible implementation of decarbonization, in the meantime, hinges on extra near-term dangers, significantly regarding power safety. Whereas geopolitical tensions roiled power markets in 2022, fragmented approaches by oil and fuel producers and shoppers “may heighten power safety dangers” throughout net-zero transitions. “Any mismatch within the tempo of demand and provide reductions may trigger very excessive or low costs, resulting in turbulent and risky markets. Uncoordinated coverage implementation may result in overinvestment in new oil and fuel capability or the untimely retirement of current infrastructure, and both of those may undermine efforts to result in safe power transitions,” it says.
Within the energy sector, electrical energy safety—making certain a dependable and secure provide of energy that may meet demand always at an reasonably priced worth—is threatened by the evolving complexity of contemporary energy methods.
The report highlights a obtrusive want for energy flexibility, which is simply set to extend sharply, owing to rising shares of variable wind, photo voltaic PV, and hovering demand. STEPS initiatives that energy system flexibility wants will greater than triple globally by 2050. Most flexibility is at present offered by dispatchable thermal energy crops and hydropower (together with pumped storage). All three situations venture further short-term flexibility could also be offered by batteries and demand response, particularly after 2030, whereas thermal and hydro assets will present seasonal flexibility. Nonetheless, new sources offering essential flexibility might arrive with the build-out of nuclear, fossil fuels with CCUS, bioenergy, hydrogen, and ammonia. As well as, demand response and curtailment of surplus era might play an “more and more essential position” nearer to 2050.
Past that, the facility sector should collaboratively execute a fragile stability. “Energy mills will must be extra agile, shoppers will must be extra linked and responsive, and grid infrastructure will must be strengthened and digitalized to assist extra dynamic flows of electrical energy and knowledge,” the IEA stated. “Adequate versatile capability must be accessible to take care of variability throughout all timescales, from the very quick time period to the very long run, throughout seasons and years. Energy methods can even must adapt to each altering local weather and climate patterns in addition to altering shopper habits.”
Grappling with New Dangers Posed by Elevated Electrification. The IEA famous that the hunt to transition to a extra electrified future by itself is riddled with dangers. Foremost amongst them is assist for know-how growth. “It’s crucial to have adequate coverage assist and enabling regulatory frameworks, environment friendly and well timed allowing and certification, whereas creating sturdy and resilient provide chains, from uncooked supplies to manufacturing and development and expert labor to making sure entry to financing,” the IEA famous.

2. Major dangers related to key clear electrification applied sciences. Supply: IEA, World Vitality Outlook 2023 |
Provide chains for clear power applied sciences pose obtrusive dangers (Determine 2). “Some relate to the truth that each the provision of crucial minerals and the manufacture of photo voltaic modules and different key items are dominated by a small variety of nations,” the report says. “Others stem from the hazard that demand will outpace the scaling up of mining, processing, and manufacturing capability alongside the provision chain, pushing up prices and constraining clear power transitions. In 2021 and 2022, for instance, greater enter costs for crucial minerals, semiconductors, and bulk supplies resulted in worth will increase for key clear power applied sciences.” Shortages of staff with particular abilities, in the meantime, are additionally slowing the enlargement of energy grids, the development of recent nuclear energy crops, and the set up of warmth pumps.
As well as, the IEA urged measures to scale back the price of financing and guarantee some certainty for revenues or price financial savings. Financing dangers embrace those who relate to the price of acquiring finance. Financing prices have just lately been pushed up considerably by rising rates of interest in markets around the globe, with substantial impacts to large-scale initiatives involving capital-intensive applied sciences like offshore wind, grid expansions, and new nuclear energy crops. “The progress of electrification will rely on lowering the price and enhancing the supply of capital. That is of specific significance for rising market and creating economies, a lot of that are at present struggling to lift the capital wanted to finance their transitions.”
The IEA additionally identified that dangers are sometimes interdependent. “An absence of coverage assist can, for instance, make a venture much less bankable, which raises financing prices. Allowing delays additionally elevate financing prices, whereas the poorer-than-expected efficiency of an asset will depress income or elevate upkeep prices. Disruptions at one stage of the provision chain can feed by means of to different applied sciences, sectors, and markets. Poor progress for one know-how also can negatively have an effect on others. Delays in extending and reinforcing energy grids, for instance, also can sluggish the deployment of renewables, warmth pumps, and EVs,” the report explains. Efforts to decrease dangers “throughout the board” might be very important, whether or not they relate to regulation and coverage, energy provide chains, and the supply of labor or entry to finance. “This highlights the necessity for a holistic method that ensures each know-how is ready to play its position in delivering safe and cost-effective electrification,” the company stated.
