Houston expert: Is China leading the global energy transition?

China plays a big role in the global push to shift from fossil fuels to cleaner energy. It's the world's largest carbon emitter but also a global leader in solar, wind, and battery technologies. This combination makes China a critical player in the energy transition. China may not be doing enough to reduce its own greenhouse gas emissions, but it is leading the way in producing low-cost, low-carbon solutions.

Why Materials Matter

One of the biggest challenges in switching to alternative energy is the need for specific materials like lithium, cobalt, and rare earth metals. These are essential for making things like solar panels, wind turbines, and batteries. In her report, "Minerals and Materials Challenges for Our Energy Future(s): Dateline 2024," Michelle Michot Foss emphasizes the critical role of materials in energy transitions:

"Energy transitions require materials transitions; sustainability is multifaceted; and innovation and growth will shape the future of energy and economies."

China controls much of the supply and processing of these materials. For example, it produces most of the world’s rare earth metals and has the largest capacity for making batteries. This gives China a big advantage but also creates risks. Michot Foss points out:

"China’s command over material supply chains presents both opportunities and risks. On one hand, it enables rapid scaling of technologies like wind, solar, and batteries. On the other hand, it exposes the global market to potential vulnerabilities, as geopolitical tensions and trade barriers could disrupt these critical flows."

China’s strategy for dominating alternative energy materials is also closely tied to its national security interests. By securing control over these critical supply chains, China not only hopes to guarantee its own energy independence but also gains significant geopolitical leverage.

“Is China’s leadership strategic or accidental? China’s dominance is a consequence of enormous excess materials supply chain and manufacturing capacity. A flood of exports are undermining materials and “green tech” businesses everywhere. It heightens vulnerabilities and geopolitical tensions. How do we in the US find our own comparative advantage?” Michot Foss notes that advanced materials should be a priority for US responses, especially as attention shifts to nuclear energy possibilities and as carbon capture and hydrogen initiatives play out.

Balancing Energy Growth and Emissions

GabrielCollins, in his report "Reality Is Setting In: Asian Countries to Lead Transitions in 2024 and 2025," offers another perspective. He focuses on how developing nations, especially in Asia, are shaping the energy transition:

"The developing world, including many countries in Asia, increasingly demand that developed nations’ policy advocacy stop treating the economic and environmental needs of the developing world as an afterthought."

Collins highlights China’s dual strategy: investing heavily in renewables while still using coal to meet its growing energy demand. He explains:

"China, which now has installed a terawatt combined of wind and solar capacity while still ramping up coal output and moving to dominate EV and renewables supply chains and manufacturing."

This strategy appeals to other developing nations, which face similar challenges of balancing energy needs with environmental goals while fostering economic growth and expanding industries.

The Numbers: Progress and Challenges

McKinsey’s Global Energy Perspective 2024 provides some useful data. On the bright side, China is installing renewable energy faster than any other country. In 2023, it added over 100 gigawatts of solar capacity, a world record. Wind energy is growing quickly too, and China leads in producing electric vehicle batteries.

But McKinsey also notes the challenges. Coal still generates more than half of China’s electricity. While renewable energy is growing fast, it’s not replacing coal yet—it’s just adding to China’s total energy capacity.

McKinsey sums it up: China is leading in renewable energy deployment, but its reliance on coal highlights the slow pace of deep decarbonization. The country is transitioning, but not fast enough to meet global climate targets.

Is China Leading or Lagging?

So, is China leading the energy transition? The answer is: it depends on how you define “leading.”

If leadership means building more solar and wind farms, dominating the materials supply chain, and being the leading supplier of low-carbon solutions, then yes, China is ahead of everyone else. But if leadership means cutting their own emissions quickly and shifting away from fossil fuels, China still has work to do.

China’s approach is practical. It’s making progress where it can—like scaling up renewables—but it’s also sticking with coal to ensure its economy and energy needs stay stable.

Final Thoughts

China is both a leader and a work in progress when it comes to the energy transition. Its achievements in renewable energy are impressive, but its reliance on coal and the challenges of balancing growth with sustainability show there’s still a long road ahead.

China’s story reminds us that the energy transition isn’t a straight path. It’s a journey full of trade-offs and complexities, and China’s experience reflects the challenges the whole world faces. At the same time, its focus on national security through energy independence and industrial strategy to build low-carbon export businesses signals a strategic move that is reshaping global power dynamics, leaving the United States and other nations to reevaluate their energy policies.

A View From HETI

No critical minerals, no modern economy. Getty images

If you’re reading this on a phone, driving an EV, flying in a plane, or relying on the power grid to keep your lights on, you’re benefiting from critical minerals. These are the building blocks of modern life. Things like copper, lithium, nickel, rare earth elements, and titanium, they’re found in everything from smartphones to solar panels to F-35 fighter jets.

In short: no critical minerals, no modern economy.

These minerals aren’t just useful, they’re essential. And in the U.S., we don’t produce enough of them. Worse, we’re heavily dependent on countries that don’t always have our best interests at heart. That’s a serious vulnerability, and we’ve done far too little to fix it.

Where We Use Them and Why We’re Behind

Let’s start with where these minerals show up in daily American life:

  • Electric vehicles need lithium, cobalt, and nickel for batteries.
  • Wind turbines and solar panels rely on rare earths and specialty metals.
  • Defense systems require titanium, beryllium, and rare earths.
  • Basic infrastructure like power lines and buildings depend on copper and aluminum.

You’d think that something so central to the economy, and to national security, would be treated as a top priority. But we’ve let production and processing capabilities fall behind at home, and now we’re playing catch-up.

The Reality Check: We’re Not in Control

Right now, the U.S. is deeply reliant on foreign sources for critical minerals, especially China. And it’s not just about mining. China dominates processing and refining too, which means they control critical links in the supply chain.

Gabriel Collins and Michelle Michot Foss from the Baker Institute lay all this out in a recent report that every policymaker should read. Their argument is blunt: if we don’t get a handle on this, we’re in trouble, both economically and militarily.

China has already imposed export controls on key rare earth elements like dysprosium and terbium which are critical for magnets, batteries, and defense technologies, in direct response to new U.S. tariffs. This kind of tit-for-tat escalation exposes just how much leverage we’ve handed over. If this continues, American manufacturers could face serious material shortages, higher costs, and stalled projects.

We’ve seen this movie before, in the pandemic, when supply chains broke and countries scrambled for basics like PPE and semiconductors. We should’ve learned our lesson.

We Do Have a Stockpile, But We Need a Strategy

Unlike during the Cold War, the U.S. no longer maintains comprehensive strategic reserves across the board, but we do have stockpiles managed by the Defense Logistics Agency. The real issue isn’t absence, it’s strategy: what to stockpile, how much, and under what assumptions.

Collins and Michot Foss argue for a more robust and better-targeted approach. That could mean aiming for 12 to 18 months worth of demand for both civilian and defense applications. Achieving that will require:

  • Smarter government purchasing and long-term contracts
  • Strategic deals with allies (e.g., swapping titanium for artillery shells with Ukraine)
  • Financing mechanisms to help companies hold critical inventory for emergency use

It’s not cheap, but it’s cheaper than scrambling mid-crisis when supplies are suddenly cut off.

The Case for Advanced Materials: Substitutes That Work Today

One powerful but often overlooked solution is advanced materials, which can reduce our dependence on vulnerable mineral supply chains altogether.

Take carbon nanotube (CNT) fibers, a cutting-edge material invented at Rice University. CNTs are lighter, stronger, and more conductive than copper. And unlike some future tech, this isn’t hypothetical: we could substitute CNTs for copper wire harnesses in electrical systems today.

As Michot Foss explained on the Energy Forum podcast:

“You can substitute copper and steel and aluminum with carbon nanotube fibers and help offset some of those trade-offs and get performance enhancements as well… If you take carbon nanotube fibers and you put those into a wire harness… you're going to be reducing the weight of that wire harness versus a metal wire harness like we already use. And you're going to be getting the same benefit in terms of electrical conductivity, but more strength to allow the vehicle, the application, the aircraft, to perform better.”

By accelerating R&D and deployment of CNTs and similar substitutes, we can reduce pressure on strained mineral supply chains, lower emissions, and open the door to more secure and sustainable manufacturing.

We Have Tools. We Need to Use Them.

The report offers a long list of solutions. Some are familiar, like tax incentives, public-private partnerships, and fast-tracked permits. Others draw on historical precedent, like “preclusive purchasing,” a WWII tactic where the U.S. bought up materials just so enemies couldn’t.

We also need to get creative:

  • Repurpose existing industrial sites into mineral hubs
  • Speed up R&D for substitutes and recycling
  • Buy out risky foreign-owned assets in friendlier countries

Permitting remains one of the biggest hurdles. In the U.S., it can take 7 to 10 years to approve a new critical minerals project, a timeline that doesn’t match the urgency of our strategic needs. As Collins said on the Energy Forum podcast:

“Time kills deals... That’s why it’s more attractive generally to do these projects elsewhere.”

That’s the reality we’re up against. Long approval windows discourage investment and drive developers to friendlier jurisdictions abroad. One encouraging step is the use of the Defense Production Act to fast-track permitting under national security grounds. That kind of shift, treating permitting as a strategic imperative, must become the norm, not the exception.

It’s Time to Redefine Sustainability

Sustainability has traditionally focused on cutting carbon emissions. That’s still crucial, but we need a broader definition. Today, energy and materials security are just as important.

Countries are now weighing cost and reliability alongside emissions goals. We're also seeing renewed attention to recycling, biodiversity, and supply chain resilience.

Net-zero by 2050 is still a target. But reality is forcing a more nuanced discussion:

  • What level of warming is politically and economically sustainable?
  • What tradeoffs are we willing to make to ensure energy access and affordability?

The bottom line: we can’t build a clean energy future without secure access to materials. Recycling helps, but it’s not enough. We'll need new mines, new tech, and a more flexible definition of sustainability.

My Take: We’re Running Out of Time

This isn’t just a policy debate. It’s a test of whether we’ve learned anything from the past few years of disruption. We’re not facing an open war, but the risks are real and growing.

We need to treat critical minerals like what they are: a strategic necessity. That means rebuilding stockpiles, reshoring processing, tightening alliances, and accelerating permitting across the board.

It won’t be easy. But if we wait until a real crisis hits, it’ll be too late.
