[Episode #159] – The Cost of Decarbonization

Why do the major groups publishing energy forecasts consistently undershoot the progress of energy transition? For decades, public sector agencies, oil industry groups, energy industry consultancies, and even environmental nonprofits have been consistently too pessimistic in their outlooks. So why is it that standard energy forecasting models keep getting transition wrong?

A group of researchers at Oxford University may have an answer to that question with a study they recently published on the future trajectory of the energy transition. The problem, they say, is that standard models don't realistically account for learning curves in manufacturing, and exponential growth in deployment as it relates to transition. Their new approach shows that future cost and deployment curves can be predicted quite accurately for energy transition solutions like solar panels, wind turbines, batteries and hydrogen electrolyzers.

What makes their demonstration particularly exciting isn’t just that they’ve found a better approach to modeling energy transition learning curves; it’s what their model shows: that a rapid energy transition is actually as much as $14 trillion cheaper than not transitioning over the coming decades. In short, these researchers suggest there is no net cost to a sustainable energy transition, and that on the economic merits at least, it’s basically inevitable.

Join us in this episode for a discussion with one of the researchers on the Oxford team, Dr. Matthew Ives. He is an economist and complex systems modeler at Oxford University who is currently researching sensitive intervention points for accelerating progress towards the post-carbon transition. We explore exactly how their modeling was done, exactly where traditional modeling has gone wrong, and what it all means for the energy transition.

[Episode #146] – Why Local Solar Costs Less

Conventional wisdom in the energy transition has long held that public investment should be directed toward utility-scale projects, because they’re cheaper than rooftop solar systems, kilowatt for kilowatt. Being cheaper, utility-scale systems would clearly deliver more bang for the buck.

Our returning guest in this episode, energy modeler Christopher Clack, says according to his recent modeling, the opposite is actually true — that investing more into local solar will deliver more public benefits than investing in utility-scale projects. And even more surprisingly, he says that building rooftop solar and distributed storage systems will actually result in more utility-scale solar as well, plus bring greater societal benefits such as more jobs, increased economic development, increased resilience, and more equitable access to the benefits of renewables. By modeling a dizzying set of factors simultaneously, Clack is able to show that combining many factors leads to synergistic effects that have been heretofore undiscovered in the literature… factors that we will attempt to describe in this extremely deep dive into energy modeling.

[Episode #144] – Investing in Energy Transition

We have a very special guest for you in this episode: Jeremy Grantham, the legendary investor who co-founded GMO, a Boston-based institutional money management firm, more than 40 years ago. With more than $60 billion in assets under management, GMO has produced steady returns for its investors through market booms and busts, largely thanks to the steady hand of Grantham and his investing philosophy, which holds that sooner or later, most valuations return to the mean.

In this interview, we talked about Grantham’s investing philosophy; the history of investment bubbles; how he values investments; what’s happening in the markets as new retail traders using the Robinhood app and participating in Reddit-based trading groups drive stocks like Game Stop wild; what the Fed should do as the world recovers from the pandemic; his views on the massive expansion of the US national debt; how the world’s governments are responding to the challenge of climate change; the role of venture capital in energy transition; and his outlook for energy transition in general.

[Episode #134] – Storage Grows Up

Battery storage in the US has grown ten-fold in just five years, and its growth is only accelerating. Just a single utility procurement announced in May of this year was for four times as much utility battery capacity as existed in the entire US five years ago.

But battery storage isn’t just getting bigger. It’s also stretching well beyond utility-scale frequency control into new applications and market segments. In fact, fully one-third of the installed battery capacity in the US now is actually on the customer side of the meter, where it is being used to do things like mitigate demand charges and provide resilience—for example, allowing a microgrid to keep functioning when grid power is shut off in a wildfire event.

And then there are all the other kinds of non-battery storage, which are finding new momentum as well. It’s an exciting time of rapid evolution in the storage sector. To help us understand it all, Jason Burwen, the Vice President of Policy at the Energy Storage Association who last joined us back in Episode #8, returns to the show for this very wonky but highly informative look at the changing market, policy environment, and technologies of storage.

[Episode #124] – Energy Transition Progress Report

As the world slowly starts to emerge from lockdown and get back to business, energy analysts and climate activists alike are wondering if we will use this opportunity to accelerate the energy transition, or if we will just go back to what we were doing before the pandemic and fire up the nearest coal-fired power plant or diesel engine.

Our guest in this episode, Nat Bullard of Bloomberg New Energy Finance, thinks the trends toward energy transition and climate action are already so firmly entrenched that we should expect them to maintain their leads as we begin to restart and rebuild the world’s economies...and he and his colleagues have ample data to prove it!

Further, he argues, the world is actually quite different now than it was in the last major economic crash a decade ago in some very important ways, particularly where it concerns energy transition. Unlike 2009, we’re not worrying about peak oil now; if anything, we’re more worried about too much cheap energy. Not just cheap oil, but more renewable power than we can use in certain places and times…so much so that wholesale and even retail grid power prices can go negative. And we’re seeing an investment community that is now much more interested in the winners of energy transition than the losers.

In this episode, we take the pulse of energy transition at this ever-so-uncertain moment, and find more than a few signs of hope and progress all over the world.

[Episode #122] – Hybrid Power Plants

The days of worrying about the intermittency of solar and wind farms are quickly receding into the past as battery storage systems are added to existing plants, and new renewable plants are increasingly equipped with large battery storage systems from the outset as so-called “hybrid” power plants. In fact, 25% of all new solar PV plants waiting to connect to bulk power systems are now hybrid plants incorporating battery systems, and on the California wholesale power market, 96% of solar PV and 75% of wind projects launched in 2019 were paired with batteries. All at prices that beat the cost of conventional power plants.

But figuring out the best way to deploy utility-scale battery storage systems isn’t just a matter of dispatchability and system balancing. In fact, it turns out that tax credit incentives and market rules are far more significant determinants. That’s one finding of a new research paper led by several researchers at the Lawrence Berkeley National Laboratory, who modeled various ways of pairing battery storage systems with utility-scale wind and solar farms. In this episode, we explore the details of this modeling with one of the paper’s authors and speculate that it might actually be better to deploy large scale storage systems independently of wind and solar farms, if market rules were more supportive of the strategy.

[Episode #99] – Metals Supply in Energy Transition

Is the supply of certain key metals—like lithium, copper, nickel, and cobalt—and “rare earth” metals—like vanadium and indium—potentially a limiter on the progress of energy transition? Or is there enough of them to realize our ambitions? Are they being produced in a sustainable way? How will the geographic concentration of these metals affect geopolitics and trade as the energy transition progresses? How confident can we be about our assessments of their abundance? And how confident can we be about how much of them we’ll need in the future, given the rapid evolution of many of these technologies, and the many alternate ways of producing them?

Our guest in this episode brings all of these questions into a whole new focus, and shows why these questions can’t be answered with some back-of-the-envelope calculation. Instead of asking whether there is enough of these metals in the Earth’s crust, he says, or about how they are mined, we should be asking much more sophisticated questions about the chemical industry, the opaque, illiquid markets in which these metals are traded, and the geopolitical implications of their trade.

[Episode #94] – Integrated Decentralized Power Systems

As more distributed energy resources arrive unbidden onto the power grid, they are increasingly requiring us not to just think about new utility business models, but to radically rethink what a utility might look like. What if millions of distributed resources become the dominant resources, and the grid assumes a subordinate role as a residual supplier of energy? What if the control of the system is also decentralized, through the actions of millions of devices? What if the roles of transmission system operators and the distribution system are diminished as their responsibilities are distributed across all those devices? And how will utilities, power market operators, regulators, legislators, and local officials deal with a radical shift in their roles and responsibilities? These are the questions that our guest in this episode—an 18-year veteran of wholesale power market design at the California ISO—thinks about, and he shares those deep thoughts with us in this wonky yet heady discussion.

[Episode #93] – Energy Transition in India and Southeast Asia, Part 2

This is Part 2 of our two-and-a-half hour interview with Tim Buckley, of the Institute of Energy Economics and Financial Analysis, based in Australia. We featured Part 1 in Episode 91, in which we primarily discussed the future of coal fired power in India. In this second part, we expand on the India story and look more broadly at energy transition across Southeast Asia, and consider the outlook for coal, renewables, and nuclear power in China, Japan, Bangladesh, Pakistan, and Malaysia, among others. As he did in Part 1, Tim shares with us in this episode a fascinating set of data on the future of energy in Southeast Asia that is oftentimes at sharp variance with the projections that we hear from energy watchdogs like the International Energy Agency. Tim tells a much more hopeful story about energy transition in the developing world. For example: If you think that China’s building more coal plants means that its coal consumption is going to go up, think again! Energy transition is moving ahead, and will move ahead, much more quickly in Southeast Asia than any of our major agencies project, and that is great news for the climate.

[Episode #91] – Energy Transition in India and Southeast Asia, Part 1

It has long been assumed that India, China, and other developing countries of Southeast Asia would power their vigorous economic growth for decades to come with coal. We heard over and over that China is building a new coal-fired power plant every three days, and about plans for multi-gigawatt sized coal-fired power plants in India. As long as coal was the cheapest form of power, addressing our climate emergency seemed like a lost hope.

But that nightmare is now evaporating thanks to the continuously declining costs for solar, wind, and battery storage. Although there are far too few policymakers (not to mention the major energy agencies, like EIA and IEA) who appear to be aware of it, the future of coal is fading by the day, as solar and wind take the lead as the lowest cost forms of power. And nowhere is this new reality more starkly evident than in India, where a remarkable pivot away from coal has been under way for about five years now, radically reshaping the outlook for India’s energy consumption, and stranding billions of dollars in investments in coal plants that will not be used as expected. At the same time, India is busily electrifying 18,000 villages, pushing forward on the electrification of transportation, and developing demand-side technologies that together are more likely to make India one of the world’s great success stories in energy transition than one of the world’s largest upcoming carbon emitters.

Our guest in this episode has been closely watching these markets for three decades, and is one of the sharpest observers of what’s happening in India and Southeast Asia. This episode is Part One of our two-and-a-half hour conversation with him, which mostly covers India and coal. Part Two of this interview will be featured in Episode 93.
