For decades, wave energy has been touted as the next big thing in renewable energy, a game-changer that will revolutionize the way we power our homes and industries. But despite the hype, wave energy has yet to make a significant dent in the global energy market. In fact, it’s not even a blip on the radar. So, what’s holding it back? And when can we expect wave energy to finally break through and become a major player in the energy landscape?

The answer lies in some of the very technologies that were meant to make wave energy more viable. Take, for example, the concept of “point absorbers,” which are essentially buoys that harness energy from ocean waves and transmit it to the shore. Sounds simple enough, right? But the reality is that these buoys can be notoriously inefficient, with some only managing to convert a paltry 1-2% of the wave’s energy into usable electricity.
And then there’s the issue of cost. Wave energy technology is still in its infancy, and the cost of building and maintaining these systems is prohibitively expensive. A single wave energy farm can cost upwards of $100 million, which is a significant investment to make when you’re still trying to prove that the technology works.

But despite these challenges, there are still some bright spots on the horizon. Researchers are working on new technologies that could potentially increase the efficiency of wave energy harvesting by up to 10 times. And companies like Principle Power and AquaBuoy are already building and deploying commercial-scale wave energy systems.
So, when can we expect wave energy to finally become a major player in the energy market? The answer is, it’s hard to say. While some experts predict that wave energy could account for up to 10% of the world’s electricity by 2050, others say it could be more like 2-3%. But one thing is certain: wave energy is not going away anytime soon.
In fact, some countries are already embracing wave energy with gusto. Portugal, for example, has set ambitious targets to harness 10% of its electricity from wave energy by 2030. And in the United States, companies like Google and Shell are investing heavily in wave energy research and development.
So, while wave energy may not be a overnight sensation just yet, it’s definitely on the rise. And as the technology continues to improve and costs come down, it’s likely that we’ll see a wave energy revolution that will leave fossil fuels in the dust. But for now, let’s just say that the future is looking a little wavy.
