Geothermal Energy: Five Key Insights from Industry Leaders

Geothermal is a proven, clean source of baseload power. Yet despite decades of operational success, it accounts for less than 1% of global electricity generation. That's about to change.Conventional hydrothermal systems are ready to deploy today, and next-generation technologies like enhanced geothermal systems (EGS), closed-loop systems, and superhot geothermal will unlock heat resources beyond naturally occurring reservoirs, dramatically expanding geothermal potential.With federal support in the United States and unprecedented private investment, we've entered geothermal's breakout decade.Geothermal Power Deck (PDF)Geothermal Heating & Cooling Deck (PDF)

The Race to Power Data Centers

The power-hungry data centers that train large AI models are driving investments in electricity generation. Whether this locks in new fossil fuel capacity for decades to come or propels the energy transition will depend on how fast developers can deliver new clean electrons.Download Deck (PDF)Download Deck (PPT)

Biofuels as an interim solution for hard-to-electrify sectors

Biofuels are uniquely positioned to help stopgap emissions in the sectors that cannot yet easily be electrified like aviation, maritime shipping, heavy trucking, and industrial heat, while emerging technologies become ready for widespread industrial-scale commercial deployment. Already a $100 billion industry in the U.S. and growing 8 percent annually, they offer an immediate, plug-in substitute for fossil fuels that works with existing infrastructure.Biofuels Deck (PDF)Biofuels Deck (PPT)

How to Measure Climate Progress

Ending reliance on oil, coal, and gas, and embracing technologies that will only improve and become cheaper over time, is not just smart climate policy. It is the best way to improve economic competitiveness and human prosperity for decades to come.

Climate Knowledge Initiative

In 2025, global climate investment topped $2.3 trillion, yet emissions continue to grow. The International Energy Agency estimates it will take triple that number to achieve net-zero. These costs imply massive opportunities, but business and financial decision-makers often rely on incomplete or biased climate information. As a result, the allocation of capital to impactful decarbonization solutions is fragmented, slow, and ultimately both inefficient and insufficient.

The Climate Knowledge Initiative translates rigorous analysis into actionable insights and helps build consensus among key decision-makers, while unapologetically flagging where business and public interests diverge. Our goal is to drive capital, talent, and innovation toward investable and scalable decarbonization solutions.​

Getting to Greener Steel

Global steelmaking accounts for over 10 percent of greenhouse-gas emissions, but tackling coalbed methane could cut the sector’s footprint by the equivalent of one billion tons of CO2 annually—at low cost. Columbia Business School's Gernot Wagner and co-author Roland Kupers explain why reducing methane is key to greener steel.

Reenergizing Nuclear Power: Key Insights from Industry Leaders

Nuclear power is safe, clean, and dispatchable. Yet, it's experiencing a paradox: while public support is at a record high, deployment remains stagnant. From extending the lives of existing large reactors to developing cutting-edge small modular reactors (SMRs) and fusion technology, different pathways promise to unlock nuclear's potential. What will it take to reenergize the industry, and which approach offers the best path forward?
