Air conditioning already accounts for 9% of electricity consumed globally, and that demand is set to grow substantially in the coming decades. While many living in hot climates need it just for comfort, others see it as a status symbol – their ticket to the middle class. For businesses, it may underpin worker productivity. BNEF's Seb Henbest and Matthias Kimmel join the show today to discuss the effect of the ever-louder hum of aircon units on global electricity demand.  Switched On is hosted this week by Head of Business Development Dana Perkins.

The loud hum of air conditioning in global electricity demand

Hydrogen’s place in the energy transition is changing. After years of hype around its role in reaching net zero, many projects have been delayed or canceled as costs remain high, policy support weakens and demand proves slow to materialize. Yet hydrogen is far from disappearing. Industries already consume vast amounts of the molecule today, and sectors such as fertilizers, refining and potentially steelmaking still have few viable alternatives for deep decarbonization. At the same time, countries like China and India continue to push ahead with deployment and industrial policy support. So after the hype cycle, where does hydrogen actually make economic sense in the energy transition? On today’s show, Tom Rowlands-Rees is joined by Martin Tengler, BloombergNEF’s head of hydrogen research, to discuss some of his department’s recent work, including “No, Iran War Won’t Boost Clean Hydrogen – Except in China” and “Hydrogen Supplier Market Shares 2026: US Blue in the Lead.”

BloombergNEF’s Tier 1 lists have become a defining feature of the clean energy industry. Built on real project deployment data, they track which manufacturers’ products are actually being used in large, recently financed projects, offering a transparent way to navigate markets crowded with hundreds of suppliers. That simplicity has made the lists highly influential, but being on (or off) the list doesn’t tell the full story about product quality or risk. So what do these lists really reveal about the industry, and how should they be used in practice? On today’s show, Tom Rowlands-Rees is joined by Jenny Chase, lead solar analyst at BNEF, to discuss the Tier 1 lists’ genesis, their application, and why they help us understand the “Wild West” of the energy transition.

The AI boom is ushering in a new era for energy storage. As data center buildout accelerates, batteries are evolving from short-duration backup tools into larger, more flexible systems that can help bring facilities online faster and manage complex power needs. In the US in particular, a growing pipeline of projects is emerging, with batteries increasingly paired with on-site generation or used to smooth demand and unlock faster connections to the grid. So how are data centers changing the energy storage market, and what role could these systems play in the power grid of the future? On today’s show, Tom Rowlands-Rees is joined by, Caitilín McManus, a technology and innovation associate at BloombergNEF, to discuss her recently released note “Data Centers’ Energy Storage Ramp Up: Project List Grows.”
