Green Investors Were Crushed. Now It’s Time to Make Money.

Invest according to your political views, and you’re unlikely to make money. Companies that appeal to left-wingers or to right-wingers might be good or bad investments, but the fact of being, on current politics, clean and union-friendly for the left or oily and gun-friendly for the right is neither here nor there. What matters is their ability to make money and how highly they are valued.

This has been rammed home for environmentally-minded investors in the past year, as a coordinated selloff in anything with green credentials crushed the idea of making money while doing good.

It turns out that the real world is tougher than advocates of ESG—environmental, social and governance—investing claimed. The lessons have been hard, but should remind investors in the sector of some of the basic facts of investing. The fall in prices has improved the outlook for the stocks.

This year has been almost universally bad for clean investments. The two worst performers still in the S&P 500 are solar companies Enphase Energy and SolarEdge Technologies, down 60% and 70%, respectively. Hydrogen stocks have fallen sharply, led by Plug Power, which warned it might not survive. Wind-farm developers have been doing so badly they have pulled out of some contracts, with Denmark’s Ørsted off 48% in dollar terms and Florida-based NextEra Energy off 29%.

Electric cars have disappointed too, hitting startups and suppliers and pushing the price of lithium ores, used to produce the battery metal, down by three-quarters or more, although market-leader Tesla’s stock has been an exception.

Just as there was a coordinated green selloff, there has been a coordinated partial rebound in the past month or so.

This provides the first lesson: debt. The clean-energy sector is dependent on vast amounts of borrowing, so high interest rates really hurt. Roman Boner, who runs a clean-energy fund at Dutch fund manager Robeco, points out that major projects are typically financed with 80% debt, so rises in financing costs have a big impact on competitiveness.

Investors who bought into green stocks probably didn’t think they were making a leveraged bet on Treasurys, but that is what they ended up with. It isn’t only about corporate financing costs, either. High borrowing costs hit consumer demand for rooftop solar and for electric cars, both of which are often leased, since leasing costs depend on the cost of debt.

At a very high level, this is about long-term thinking. Low rates encourage investors to think long term, because they make future profits almost as valuable as current profits, and encourage borrowing to try to secure those future profits.

High rates encourage short-term thinking, by making profits today far more valuable than future profits—why bet on the future when you can earn 5% from Treasury bills? Short-term we get fossil-fuel profits, while long-term we get either clean energy or global warming; recently investors have been encouraged by rising rates to think short term.

The second lesson: government. Ronald Reagan overstated it when he said: “The nine most terrifying words in the English language are: ‘I’m from the government, and I’m here to help.’” But investors who rely on state subsidies to ensure profits leave themselves at the mercy of both fickle politicians and the bureaucrats Reagan was concerned about. This year’s selloff has been worsened by the bureaucrats and their failure to provide the details of many of the subsidies promised in last year’s badly named Inflation Reduction Act.

“We’re still hoping to get them by year end,” says Ed Lees, co-head of the environmental strategies group at BNP Paribas Asset Management. The next problem might be the politicians, at least if Donald Trump wins the presidency and torches the IRA. Lees thinks this will be hard, because so many IRA-subsidised projects are heading for Republican states. But Trump certainly has no sympathy for environmental causes.

The third lesson is the one most relevant to buying today: valuation. Buying stocks when they are trendy and wildly overpriced is a recipe for disaster. Perhaps the most extreme example of late is the L&G Hydrogen Economy ETF, launched in London at the height of clean-energy excitement in February 2021. It plummeted from day one, never regained its launch price, and is down 55% since then.

“We’ve seen a very harsh reality check,” said Sonja Laud, chief investment officer of L&G Investment Management.

The question is whether the hype has left. Laud worries that one year of high rates won’t have crushed all the excesses built up in 12 years of near-zero rates. But clearly valuations are much lower than they were, and she is hopeful there are opportunities to be found now.

“The huge green premium you had previously is no longer there,” says Velislava Dimitrova, who runs sustainable funds at Fidelity International. Clean-energy stocks are “much more interesting than they used to be—I don’t believe that renewables are dead.”

In the bond market, investors are no longer paying much if any “greenium,” or extra price for green bonds. In stocks, it is harder to judge: The S&P Global Clean Energy index trades at a discount to the global market on some measures, but not others, making it difficult to conclude that the sector as a whole is a wonderful bargain.

Still, it is good news for buyers that the hype has evaporated. Investors who care about profits more than purpose can finally consider clean-energy stocks again.

For decades, the world’s computing power has quietly expanded at an astonishing pace.

From the first transistor developed at Bell Labs in 1947 to modern processors containing billions and even trillions of transistors, each generation of technology has been faster, smaller and more powerful than the last.

But according to quantum physicist and technology entrepreneur David Reilly, that era of effortless progress is beginning to slow.

Reilly, CEO of Sydney-based Emergence Quantum and Professor of Physics at the University of Sydney, says the computing infrastructure underpinning modern economies is approaching fundamental physical limits.

And that could have enormous implications for finance, artificial intelligence and global investment.

Speaking at an industry event organised by Kanebridge International, Reilly said many critical parts of modern society depend on computing and the infrastructure used to process information.

The slowdown behind the tech boom

For years, the technology industry relied on a steady improvement known as Moore’s Law, where the number of transistors on a chip doubled roughly every two years.

More transistors meant more computing power, allowing faster software, smarter devices and ever-larger data systems.

Today, however, those gains are slowing.

“It feels to me very innate that I’m going to just find that next year there’s going to be another breakthrough,” Reilly said.

“But if you look at the data…there’s a slowing down, a roll off in performance that started some 10, 20 years ago.”

Rather than making chips dramatically faster, manufacturers are now largely increasing computing capacity by packing more transistors onto each processor.

The approach works, but it comes with growing complexity, higher costs and increasing energy demands.

The brute-force race for AI

That challenge is already visible in the massive data centres being built to support artificial intelligence.

In the race to dominate AI, companies are constructing vast computing facilities that consume huge amounts of electricity and water. Reilly described this expansion as a “brute force” approach driven by the global competition to develop advanced AI systems.

Yet the demand for computing power continues to accelerate.

Artificial intelligence, advanced robotics, healthcare research, pharmaceuticals and cybersecurity all require far more processing capacity than today’s systems can easily deliver.

The question now facing the technology sector is whether traditional computing can keep up.

Enter quantum computing

That is where quantum computing enters the conversation.

Unlike conventional computers, which process information using binary switches that represent ones and zeros, quantum computers exploit the unusual behaviour of particles at the atomic scale.

Reilly describes them as a fundamentally different type of machine.

“So a quantum computer is a wave computer,” he said.

Instead of processing information through simple on-off switches, quantum systems can use wave-like properties of particles to process many possible outcomes simultaneously.

Those waves can interact in complex ways, reinforcing correct solutions while cancelling out incorrect ones. In theory, this allows quantum systems to tackle certain types of problems dramatically faster than classical computers.

What it could mean for finance

The concept may sound abstract, but its potential applications are significant.

Quantum computers are expected to transform areas such as materials science, chemical modelling and pharmaceutical development.

They could also help solve complex optimisation problems in logistics, finance and risk management.

For financial institutions in particular, the technology could offer new tools for detecting fraud, analysing market behaviour and optimising portfolios.

But the shift will not happen overnight.

“One message to take away is that quantum is not going to suddenly solve all of your problems,” Reilly said.

Instead, he said quantum systems will likely complement existing computing technologies as part of a broader and more diverse computing ecosystem.

Why data centres may soon “go cold”

One key change already emerging is how computing systems are physically designed.

Many next-generation technologies, including quantum processors, operate far more efficiently at extremely low temperatures. As a result, future data centres may rely heavily on cryogenic cooling systems to manage heat and energy consumption.

Reilly believes that the shift will gradually reshape the computing industry.

“Over the next five years, you’re going to see data centres go cold,” he said.

“And as that happens, they almost drag with them new compute paradigms.”

Emergence Quantum, the company he co-founded, is focused on developing technologies to support that transition, including cryogenic electronics and integrated hardware platforms designed for quantum computing and energy-efficient systems.

A new technological era

For investors and businesses, the technology remains in its early stages. But the scale of global interest is growing rapidly.

Governments, research institutions and technology companies are investing heavily in quantum research, betting it could become a foundational technology for the next generation of computing.

For Reilly, the moment feels similar to earlier technological turning points.

In the 19th century, new discoveries in thermodynamics helped drive the development of steam engines and the Industrial Revolution. In the 20th century, advances in electromagnetism led to radio, television and eventually the internet.

Quantum physics, he suggests, could represent the next chapter in that story.

“Today we have, as a society, in our hands new physics that we’re just beginning to figure out what to do with,” Reilly said.

“But I think it’s an exciting time to be alive and watch what happens over the coming decades.”
