A Drop in Interest Rates Could Boost Renewables

If the Federal Reserve cuts interest rates in the coming weeks, a friendlier borrowing environment could make all the difference for some mothballed renewable-energy projects.

The returns generated by such projects once they are up and running are often predictable and modest, but because they require a large upfront expenditure, frequently funded in part by debt, they are sensitive to interest-rate fluctuations.

With recent economic data suggesting the Fed has plenty of room to cut, some investors say now is the time to get moving on renewable plans.

Thomas Byrne, chief executive at solar investor CleanCapital, said a drop in interest rates would affect a “not inconsequential amount” of solar developments under consideration. “We have had projects on hold that simply don’t make economic sense for us anymore because the borrowing cost was too high. So those projects will immediately unlock,” he said.

Byrne estimates some of these projects could begin construction by the end of the year and start generating energy next summer.

Solar and wind energy in particular stand to gain from lower borrowing costs, said Srinivasan Santhakumar, principal research analyst with the research firm Wood Mackenzie. “Higher interest rates have disproportionately affected the economics of wind and solar projects,” he said.

An interest-rate increase of 2 percentage points could result in a 20% jump in the cost of producing energy for utility-scale solar power over the life cycle of a project, according to a Wood Mackenzie analysis released in April. In comparison, the same increase might boost the cost of producing energy from gas by 10% to 12%.

Some developers may wait to see a steeper drop before making moves. “It’s definitely a phenomenon, particularly for the more sophisticated, more longer-standing developers who’ve had a history of surfing the ups and downs of the interest-rate spectrum and are also aware of the consequences for their own balance sheet of a long-term interest rate rise,” said Katherine Mogg, managing director at the New York Green Bank, a state-sponsored investment fund that focuses on filling gaps in energy transition financing. Mogg said she expects to see a modest uptick in requests for proposals in the coming months.

The Federal Reserve has signalled a rate cut at its next meeting in September, and most futures investors expect a quarter-percentage-point reduction, according to CME FedWatch. More than three quarters of investors expect the Fed to lower its benchmark rate, now in a range between 5.25% and 5.5%, by at least a full percentage point by year-end.

While a cut in interest rates is a positive for renewables financing, a durable boost for green projects may require a Goldilocks economic scenario in which a cut to borrowing costs don’t coincide with rising fears of a global recession, which could in turn drive investors away from the U.S., said Ron Erlichman, partner at the law firm Linklaters.

“There are a lot of different factors, like the old cliché of ‘headwinds,’ that affect transactions,” he said, adding that large-scale projects such as offshore wind, hydrogen and carbon capture frequently rely on foreign investment.

Fears of unchecked inflation and rampant increases in the cost of materials have cooled down somewhat in the past year, he said, but the looming U.S. election brings a fresh element of uncertainty . While many see a low probability of a full rollback of the Inflation Reduction Act, the legislation that provides game-changing tax breaks for renewables, an executive branch hostile to green energy could slow project permitting or otherwise “nibble at the fringes” of the landmark legislation, as Byrne put it.

“Having done this awhile and seen the cycles in the market, I still remain incredibly optimistic about renewables and energy transition in the United States,” Erlichman said.

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.”
