Providing a stable energy supply is often described in terms of a “trilemma”—a balance between supply security, environmental sustainability, and affordability. Of the three pillars of energy supply, security is the easiest to take for granted. Supply seems fine until it isn’t. Security of fossil fuel supply is particularly easy to ignore in countries that are striving to greatly reduce their fossil fuel consumption for climate reasons. The political focus is on building renewable energy and zero-carbon systems, and mitigating the economic, social, and political costs of transition; the thought was that the existing system would take care of itself until it was phased out. This was the case for much of Europe until two years ago.
