Jenny Chase went to work for the London-based startup New Energy Finance in 2005, straight out of university in Cambridge. She founded its solar analysis team and helped establish some of the first reliable indexes of prices in the solar supply chain, as well as some of the first serious industry models and projections.

The solar power industry barely existed then. Now solar is the cheapest source of new power in most markets and the International Energy Agency expects it to dominate global electricity by 2050. Throughout that heady transition, Chase has run and grown the solar analysis team, even after the company was bought by Bloomberg and became Bloomberg NEF in 2009. It has become one of the most respected teams in the business and a widely cited arbiter of industry data.

In 2019, Chase wrote a book summarizing what she learned over her years analyzing the industry. It is called Solar Power Finance Without the Jargon, but the title is somewhat misleading — it covers solar power finance but also solar power history, technology, and policy. It is leavened here and there with droll bits of biography or advice from Chase and contains an incredible amount of information in a highly compact and readable package, just over 200 pages.

A heavily updated second edition was released this month. Also this month came Chase's yearly “opinions about solar” Twitter thread, which is highly anticipated among a certain kind of energy dork [waves].

I figured it would be fun to have Chase on the pod to talk about the current state of the solar industry, whether anything but standard-issue solar PV is ever going to flourish, and what the world needs to help balance out increasing penetrations of solar.

Okay then. Jenny Chase from Bloomberg NEF. Welcome to Volts. Thank you so much for coming.

Jenny Chase

Thank you so much for inviting me, David.

I read your book over the past week and it's just delightful. I really recommend it to anyone. I feel like the title is a little well, I guess it does say without the jargon, but I just feel like the word finance is going to scare off some readers. But it's really just a nice, extremely approachable introduction to this whole thing of solar in the markets and how it's funded and how it's proceeded over the years. So I really was charmed by it. I noticed actually that it had a little bit of kind of autobiography in the first few chapters and I thought it was really kind of funny.

I had never really thought about it, but you and I have some parallels in our history. We sort of snuck into what was at the time a relative backwater in the world right around 2004, I think, both of us, and then just kind of hung around.

Jenny Chase

Absolutely. And I can't get another job, so I'm stuck doing solar at Bloomberg NEF now.

David Roberts

Same, we've been doing this for so long now that I couldn't really do anything else, but we just kind of planted ourselves and stuck around until the area we were in suddenly became huge around us.

Jenny Chase

It's a pretty good place to be planted, though. I mean, back in 2004, I was looking at this industry, and I started specializing in solar in late 2005. And I was like, "One day this might be 1% of global electricity supply, but, you know, that's worth working on. Even 1%, it's worth working on if we can make it clean." And last year, it was 5%, and it isn't done growing.

David Roberts

Same, I started covering climate change during the George W. Bush administration. I was like, maybe someday someone will do something about this. Maybe someday we'll pass legislation. And then here we are. PV dominates the world. People are targeting net zero. How things change.

Jenny Chase

Yes.

David Roberts

So I want to ask you, you have been following now the solar industry. I mean, honestly, one of the coolest, most fun, most sort of, like, optimistic of all the dark things h...
