As we continue to grapple with the existential threat of climate change, it’s astonishing that wave energy remains one of the most underutilized sources of renewable power. With the world’s oceans covering over 70% of our planet, it’s mind-boggling that we haven’t yet harnessed the sheer energy potential of waves to fuel our civilization. But, as I’m about to argue, it’s not that we’re not trying – it’s that we’re not trying hard enough. Or, rather, in the right way.

For decades, wave energy has been touted as a promising technology, but its adoption has been slow, and its potential has been grossly underestimated. The conventional wisdom is that wave energy is too expensive, too unpredictable, and too far out to sea. But what if I told you that these criticisms are based on a flawed understanding of the technology itself? What if I told you that wave energy has the potential to not only mitigate climate change but also to help us transition away from fossil fuels and create a more sustainable future?
The truth is, wave energy has been around for over a century, with the first commercial wave power plant opening in Portugal in 2000. Since then, numerous technologies have been developed, from tidal stream generators to oscillating water columns, but despite these advances, wave energy remains a niche player in the renewable energy landscape.

So, what’s holding us back? For one, the cost of wave energy has been notoriously high, with estimates suggesting that it can cost upwards of $1,000 per megawatt-hour to generate electricity from waves. Compare this to the cost of solar and wind energy, which can be as low as $30 per megawatt-hour. However, experts argue that these costs are based on outdated assumptions and that the real cost of wave energy is actually much lower.
Another hurdle is the predictability of wave energy. Unlike solar and wind, which can be harnessed on land, wave energy is tied to the ocean’s tides and currents, making it harder to forecast and predict. But what if I told you that this unpredictability can actually be a strength? Wave energy can provide a constant, reliable source of power, even on cloudy or windless days.
And then there’s the issue of scalability. Wave energy is often seen as a small-scale, boutique technology, limited to niche applications like powering coastal communities. But what if I told you that wave energy has the potential to be scaled up to meet global energy demands? In fact, some experts estimate that the world’s oceans could provide up to 1,000 times more energy than the world’s entire current energy demand.
So, what does the future hold for wave energy? In recent years, there’s been a surge of investment and innovation in the sector, with companies like OpenHydro and Verdant Power developing new technologies and business models. Governments too are starting to take notice, with initiatives like the European Union’s Wave Energy Pilot Project and the US Department of Energy’s Wave Energy Converter (WEC) program.
As we look to the future, it’s clear that wave energy is not just a niche technology but a game-changer. With the right investment, innovation, and policy support, wave energy could help us transition away from fossil fuels, mitigate climate change, and create a more sustainable future. So, let’s not underestimate the power of waves – let’s harness their energy to save ourselves from ourselves.
