In part one of this series, I explored how we're rethinking sources of ocean energy — from thermal gradients to nuclear SMRs to currents. But understanding energy in the ocean means looking at both sides of the equation. This time, I want to talk about uses: where energy is being consumed in ocean and coastal environments today, where demand is shifting, and where new opportunities are emerging. Because reimagining energy infrastructure only matters if it maps to real demand. And in the ocean, that demand is not only changing — it’s being reshaped by concerns about energy security and shifting cost curves.

When most people think of energy from the ocean, four primary sources typically come to mind: offshore wind, offshore oil and gas, wave, and tidal power. And for good reason — these are the legacy sectors that have absorbed decades of capital and engineering focus.

In the last 60 years, natural disasters, driven by climate change, are punishing coastlines at a far greater rate than inland disasters (see graph). Furthermore, the extremes of these events will worsen and may likely increase in frequency. Not to mention the fact that 40% of the world’s population lives in, commutes through, works around, and is otherwise part of this impact zone.
