Temasek views the energy transition not as a binary switch from brown to green, but as a gradual progression through many intermediate shades. This pragmatic approach justifies investing in transitional fuels like LNG and advanced technologies like nuclear fusion, acknowledging the need for energy security and affordability.

For new nuclear tech, competing with cheap solar on cost is a losing battle. The winning strategy is targeting "premium power" customers—like the military or hyperscalers—who have mission-critical needs for 24/7 clean, reliable energy and are willing to pay above market rates. This creates a viable beachhead market.
While solar panels are inexpensive, the total system cost to achieve 100% reliable, 24/7 coverage is massive. These "hidden costs"—enormous battery storage, transmission build-outs, and grid complexity—make the final price of a full solution comparable to nuclear. This is why hyperscalers are actively pursuing nuclear for their data centers.
The massive energy consumption of AI has made tech giants the most powerful force advocating for new power sources. Their commercial pressure is finally overcoming decades of regulatory inertia around nuclear energy, driving rapid development and deployment of new reactor technologies to meet their insatiable demand.
Temasek evaluates global investments on two fronts: financial returns and the strategic insights they generate. This "network effect" allows them to transfer knowledge from one portfolio company to others, enhancing value across their entire ecosystem and justifying investments beyond pure financial metrics.
Instead of tackling multiple downstream symptoms, identify and solve the single upstream "lead domino" problem. For example, making energy abundant and cheap through nuclear power makes complex challenges like recycling and carbon capture economically and technically feasible, rather than performative, inefficient gestures.
Unlike typical sovereign funds that manage reserves, Temasek directly owns its assets. This structure necessitates actively selling assets ("recycling capital") to fund new investments, creating a disciplined trade-off between holding long-term winners and pursuing new opportunities.
Beyond environmental benefits, climate tech is crucial for national economic survival. Failing to innovate in green energy cedes economic dominance to countries like China. This positions climate investment as a matter of long-term financial and geopolitical future-proofing for the U.S. and Europe.
Recognizing that investment capabilities alone are insufficient, Temasek proactively established a geopolitical team and a Washington D.C. office in 2017. This was done not in reaction to a crisis but in anticipation of global shifts that could have widespread ramifications on their portfolio.
A large government commitment, like the $80 billion nuclear development plan with Westinghouse, does more than create a single customer. It acts as a powerful catalyst for the entire industry. This de-risks the supply chain, signals market viability, and attracts massive private capital (e.g., Brookfield), creating tailwinds for all players.
Unlike Norway's model of direct government ownership, Singapore's Temasek acts as a holding company. This structure allows it to convene portfolio company leaders (e.g., in a Sustainability Council) to share insights and best practices, creating synergies that would be impossible with disparate ownership.
