Investing in green tech

Episode Summary

Executive Summary: The episode examines how investors make money from climate and green technologies that are unproven, not yet scaled, or still need major breakthroughs. Simon Mundy profiles Vinod Khosla’s high-risk, high-upside strategy: backing technologies that can be profitable without subsidies if they work. The discussion contrasts venture-style climate investing with the need for broader government policy, especially carbon pricing, and ends by noting the UK Labour government’s more pro-green, pro-investment stance.

Main Topics: The challenge of investing in climate tech uncertainty (Priority: 5/5): The hosts frame the central problem: many solutions needed for decarbonization are either not yet available or not proven at scale, making investment timing and returns highly uncertain. Vinod Khosla’s climate investment strategy (Priority: 5/5): Mund y explains Khosla’s background and his venture approach: accept frequent failure, but target a few massive winners in climate tech. Breakthrough technologies vs. incremental deployment (Priority: 4/5): The conversation contrasts existing technologies that should be deployed faster (solar, wind, EVs) with sectors like steel and cement that may require new breakthroughs. Fusion power as a high-risk bet (Priority: 5/5): Fusion is presented as one of Khosla’s most exciting investments, with Commonwealth Fusion Systems aiming to build a prototype power station and attract major capital. Policy, subsidies, and carbon pricing (Priority: 5/5): Katie argues that venture funding alone cannot solve the transition and pushes carbon pricing as a more effective, economy-wide incentive mechanism than subsidies. UK Labour government and green investment (Priority: 4/5): The discussion closes on how the new UK government is courting business and framing green investment as a competitiveness strategy rather than a purely environmental one.

Key Arguments: A lot of climate tech still does not exist or has not been proven at scale, so investing in it requires tolerating large uncertainty. Khosla’s model is to back companies that can become profitable without subsidies; he is not focused on iterative improvements. Fusion is no longer dismissed by serious investors and scientists; major capital is flowing into prototype development. Existing clean technologies already available should be rolled out faster, even as some hard-to-abate sectors need new solutions. Government support matters, but the speaker argues carbon pricing is a better systemic tool than relying on subsidies or venture capital alone. The UK Labour government is viewed as more receptive to green investment and is positioning decarbonization as part of long-term national competitiveness. Climate venture investing works like classic VC: most bets fail, but the winners can be enormous and reshape entire sectors.

Data Points: Survey deadline: August 29 - Listeners are invited to complete a survey by this date to enter a prize draw. Prize: Pair of Bose QuietComfort 35 wireless headphones - Incentive for completing the pre-deadline listener survey. Khosla Ventures founded: 2004 - Vinod Khosla launched his venture firm around this time. Fusion company funding: About $2 billion - Commonwealth Fusion Systems has raised this amount from investors. Climate tech vision cited: Half of the technology needed - Katie references John Kerry’s claim that about half of needed emissions cuts will come from yet-unknown technology. UK decarbonization target: 2030 - Labour’s manifesto target mentioned for decarbonizing the electric grid.

Pivotal Quotes: "half of the emissions cuts that we need, will come from technology that we don't have yet" — Simon Mundy: Citing John Kerry to illustrate the belief that new climate technologies are still needed. "he's completely focused on the things that don't exist yet" — Simon Mundy: Describing Vinod Khosla’s investment philosophy of backing breakthrough technologies rather than incremental ones. "I would venture that there are many, perhaps most, car journeys, especially in cities, that you don't actually need to take a car" — Simon Mundy: His closing 'long' pick, arguing against unnecessary urban car use.

Implications: Green investing remains a bet on uncertain breakthroughs, not just existing solutions. For listeners and industry, the episode suggests climate finance needs both bold private capital and stronger public policy—especially carbon pricing and supportive regulation—to scale the transition.
