The future of the clean energy transition

More than 60 countries held elections in 2024, shaping a new world order amid a wave of anti-incumbent voting. The US presidential election — which marked Donald Trump’s return to the White House — was arguably the most consequential election of the year, with populist rhetoric and headlines raising fears that the global energy transition could be halted, or reversed, amid ongoing pledges to “drill, baby, drill”.

But let’s separate rhetoric from reality by focusing on the trend lines, not the headlines:

  • The economics have never been better — Falling costs, technological breakthroughs and encouraging clean-tech learning curves have reduced the cost of clean energy below that of fossil fuels in many regions. Roughly 81% (382 GW) of newly installed renewable power projects in 2023 were cheaper than fossil fuel alternatives.1 The energy transition is no longer a matter of averting global warming, but of basic economics and good business. Emerging economies, with their increasing power demands and rapid urbanization, should accelerate the adoption of clean energy, especially solar energy, purely for affordability reasons.
  • Energy autonomy = energy security — In the wake of Russia’s invasion of Ukraine, and the resulting surge in gas prices which sparked Europe's most significant energy crisis since the 1970s, most EU countries have accelerated renewable energy deployment. China also continues to strengthen its resilience to global oil and gas price volatility through expanded renewable energy initiatives. It installed a staggering 358 GW of solar and wind capacity in 2024,2 a 45% and 18% year-on-year increase from end-2023 levels, respectively. As geopolitical disruptions continue to create oil and gas price volatility, more countries could follow their lead.
  • China dominates clean energy supply chains — In 2024, global investment in clean energy reached $2 trillion (USD),3 double the investment in fossil fuels. While America’s retreat from the clean energy space might not look good, it is already a relatively small player in the space, accounting for only around 15%3 of global clean energy investment. As such, it has limited ability to affect the trajectory of the global energy transition. China dominates global clean-tech supply chains, at every stage, across multiple technologies and could capitalize on America’s retreat to build on an already commanding lead and solidify its market leadership position.

The technological and economic tailwinds powering the clean energy transition are just too strong for a single nation, or head of state, to overcome. The Trump administration’s policies might slow (not halt) the US transition but could harm US competitiveness in the clean-tech space, allowing China to pull further ahead. The transition in the rest of the world will likely power ahead. So, as the US embraces “drill, baby, drill” while much of the rest of the world increasingly adopts a “build, baby, build” stance towards renewables, the real question is: Will America be left behind in the great energy transition?

Better (and continuously improving) economics

Costs for constructing new wind and solar installations have decreased substantially in recent years, eliminating a key barrier to widespread adoption. The levelized cost of electricity (LCOE) measures the average cost of electricity generation over the lifetime of a power plant. The global weighted average LCOE of newly installed utility-scale solar PV projects fell by 90% over 2010-2023, making it 56% lower than the average cost of fossil fuels in 2023. Offshore and onshore wind have seen similar (albeit less dramatic) cost declines. In 2023, the global weighted average LCOE of new onshore wind projects was 67% lower, and offshore wind was 25% less expensive, compared to the weighted average cost of fossil fuels. Roughly 81% (382 GW) of newly installed renewable power projects in 2023 were cheaper than fossil fuel alternatives. Globally, new solar and wind projects are priced lower on production costs compared to new gas and coal plants in nearly every market, according to BNEF (Bloomberg New Energy Finance).4

Moreover, once installed, clean energy systems are, in general, relatively cheap to maintain. The adoption of renewable power has saved an estimated $409 billion (USD) in fuel costs globally in the electricity sector over 2000-2023.5

Why is it that renewable energy continues to become cheaper, while fossil fuels haven’t seen similar efficiency gains?  Wright’s Law. In its simplest terms, with each doubling of production of an item, its costs decrease by a certain consistent percentage. In other words, renewable energy technologies are following steep learning curves: each doubling of installed solar and wind capacity results in price declines of roughly 20%.6 Similarly encouraging learning curves on batteries (the most expensive component of an electric vehicle (EV), have led to sharp cost declines over the last decade, which could, in turn, continue to drive down prices of EVs leading to mainstream adoption.

Energy autonomy in a time of geopolitical disruption

The EU has an ambitious plan to achieve energy costs savings of around €260 billion annually by 2040.7 A large part of this plan hinges on ensuring that electricity bills will not be dictated by volatile gas prices, through the accelerated deployment of renewable energy and associated grid infrastructures. Crucially, this structural shift could strengthen the region’s energy security by reducing its vulnerability to imported gas from Russia, an issue that rose to the forefront of EU policy agendas in the wake of Russia’s 2022 invasion of Ukraine. The subsequent surge in gas prices forced European nations to seek cheaper and cleaner energy options. In the aftermath, fossil fuels have lost their hold on the EU energy market: renewable energy's share has grown from 34% in 2019 to 47% in 2024,8 while the share of fossil fuels has decreased from 39% to a low of 29%. Wind and solar capacity added since 2019 has helped the EU to avoid €59 billion worth of fossil fuel imports.  

This isn’t an isolated phenomenon. About six billion people reside in countries that depend on fossil fuel imports,9 exposing them to oil and gas price volatility caused by geopolitical disruptions. Many of these countries are investing heavily in domestic renewable energy projects. China, for example, added a staggering 358 GW of solar and wind capacity in 2024, a 45% and 18% year-on-year increase from end-2023 levels, respectively. Similarly, India installed 24 GW of renewable energy (primarily solar energy) in 2024,10 corresponding to more than half of New York State’s entire net summer electricity capacity.11 The IEA, in its main case scenario, projects 5,500 gigawatts (GW) of new renewable capacity to become operational by 2030, with China accounting for 60% of this expansion.12

Who wins in America’s retreat from the clean energy stage?

Global clean energy investment reached $2 trillion (USD) in 2024, double the investment in fossil fuels. As this gap continues to widen in tandem with accelerated investments in clean energy, China should be the biggest beneficiary of the projected growth. It already has a commanding lead across clean-tech supply chains ranging from solar panels and EVs to batteries, as well as a virtual monopoly on the processing and refining of critical minerals which are essential for the energy transition. If the US chooses to promote domestic oil and gas production over investing in reshoring of clean-tech supply chains, it could leave a clear path for China to build on an already commanding lead and solidify its market leadership position. To put it in context:

  • Chinese auto brands accounted for over 60% of global EV sales in 2024.13
  • Fewer than 3% of the solar panels installed in the EU are manufactured in Europe.14
  • China accounts for 60% of production of rare earth elements and processes 85% of them.15 Rare earth elements (the collective term for a group of 17 metals) are used in renewable energy technologies (EV batteries, solar panels and wind turbines) as well as general consumer electronics.

Conclusion

The decline in renewable energy costs, driven by technological advancements and steep learning curves, has favourably positioned clean energy to undercut fossil fuels in terms of production costs. Moreover, the global shift towards renewables is not only an economic imperative but also a strategic move to enhance energy security amidst geopolitical uncertainties. As the clean energy transition accelerates, it could unlock a vast array of new opportunities for investors who are willing to take a long-term view. As winners and losers emerge, making informed choices will be essential for investors in positioning their portfolios to effectively navigate what could be the greatest structural shift in our society since the Industrial Revolution.
