Investing in Energy Without Regret
How the minimax-regret mindset — borrowed from decision science — can help energy investors navigate a world of deep uncertainty.
A Question That Changed the Course of History
In 1994, Jeff Bezos left a secure Wall Street job to chase a fragile idea: selling books online. His reasoning? "When I'm 80, will I regret not having tried?" It wasn't about predicting whether the internet would succeed. It was about avoiding the sting of future regret. Energy investors today face a similar challenge — and the same question applies.
The Logic and Psychology of Minimising Regret
The principle Bezos used has deep roots in decision science. In the 1950s, Leonard Savage and later Raiffa & Luce formalised the "minimax regret criterion." The idea is simple: instead of asking "What's the most likely outcome?", ask "Which decision minimises the regret I'll feel if things turn out differently?"
In practice: define your options and scenarios, compute each option's regret per scenario (the gap to the best outcome), then choose the option with the smallest maximum regret.
Regret is one of the most powerful human emotions — so powerful that we often fear regret more than loss itself. Research shows that we anticipate regret before it even happens, and this "anticipated regret" quietly shapes our choices. That's why the minimax-regret approach resonates: it blends rational analysis with emotional reality.
Minimax Regret vs. Maximising Value
Finance traditionally focuses on maximising risk-adjusted NPV/EMV. But chasing peak expected value can create fragile single bets that shine in one future and stumble in others. The two goals can often be reconciled by designing for flexibility — staged decisions, modular assets, and real options — moving along a Value–Regret Frontier.
The High Stakes of Energy Investing
Few sectors face more uncertainty than energy. A solar farm, hydrogen hub, or gas pipeline isn't just a project — it's a bet that spans 20 to 30 years, locked into place long before the future is clear.
Policy Swings
A sudden carbon tax or subsidy shift can flip project economics overnight. Regulatory changes that seemed distant can arrive suddenly, turning attractive assets into stranded liabilities.
Technology Breakthroughs
Cheaper batteries or green hydrogen can upend entire markets. Assets built around today's cost curves may find themselves uncompetitive within a decade — or sooner.
Price Volatility
Fossil fuel markets remain unpredictable and cyclical. The IEA's World Energy Outlook 2024 warns that policy uncertainty and financing hurdles are slowing clean energy growth in developing regions — yet IRENA reports 81% of new utility-scale renewable projects in 2023 were already cheaper than fossil fuel alternatives.
The Pain of "If Only"
Regret comes sharply into focus when assets are stranded. Imagine financing a gas pipeline, only to see it underused within a decade as demand collapses and regulations tighten. This is no hypothetical. The IEA's Net Zero Transition scenarios highlight significant stranded-capital risk across midstream oil and gas infrastructure.
For those caught on the wrong side of the shift, the financial losses are painful — but the real sting is the thought: "If only we had chosen differently."
Investing With Foresight, Not Fear
Bezos wasn't chasing certainty — he was avoiding regret. Energy investors can do the same. In a future shaped by shifting policy, disruptive technology, and volatile markets, the minimax-regret mindset blends logic with pragmatism to build portfolios that are robust across a wide range of outcomes.
It's not about perfect forecasts. It's about making choices you can stand behind tomorrow — and decades from now.
