America's Untapped Power: Why Wave Energy Still Waits For Its Moment

Wave energy devices must survive corrosive seas and violent storms.

By EVWorld.com Si Editorial Team

The United States is surrounded by an ocean of power - literally. Federal estimates suggest waves off America's coasts carry energy equal to a large share of national electricity demand. It is clean, abundant, and relentlessly renewable. And yet, while solar panels glint from rooftops and wind turbines spin across the plains, wave energy remains a promise rather than a presence.

Why has this resource been so slow to come online? The reasons converge at the intersection of engineering, economics, and regulation.

The ocean fights back

Harnessing waves is not like planting a turbine in a cornfield. The ocean is a brutal testing ground. Devices must withstand saltwater corrosion, powerful storms, and the constant mechanical punishment of waves. Building machines that both survive and efficiently capture energy is a formidable challenge, and early prototypes often failed or required costly maintenance that scared off investment.

Unlike wind and solar, which matured into standardized designs, wave energy is still in its experimental phase. Some companies are betting on floating buoys that rise and fall with swells. Others are testing oscillating water columns or hinged platforms. With no clear winning architecture, scaling is slow and costs remain high.

Red tape at sea

Even if the technology were ready, developers face complex permitting. U.S. waters are governed by a patchwork of agencies with overlapping jurisdictions for environmental protection, shipping, fishing, and coastal use. Securing approval can take years, stalling projects before they ever touch the water.

That is why federally approved test sites like PacWave South off the Oregon coast matter. They let companies connect prototypes to the grid and prove performance under real conditions. By streamlining testing and data collection, they can help move wave energy from lab to market.

The money question

Offshore projects are expensive, and investors prefer technologies with proven cost curves. Solar and wind enjoyed decades of learning-by-doing, mounting policy support, and steep price declines. Wave energy is earlier in that journey. Advocates argue that targeted public funding, predictable permitting, and bankable offtake contracts could unlock private capital and push designs toward scale.

A future worth betting on

Despite the hurdles, the potential is hard to ignore. Waves are more predictable than wind and available day and night, offering a steady complement to other renewables. For coastal communities, wave farms could deliver local, resilient power while reducing dependence on fossil fuels.

The story of wave energy today resembles wind power in the 1980s - promising, messy, and uncertain. But persistence pays off. America's oceans are restless, and so are the innovators determined to harness them. Wave energy will matter. The open question is how soon we will let it.
