Underwater Tidal Turbine Powers 2,000 Homes With Ocean Energy
Affiliate Disclosure
Hey fellow impactful ninja ?
You may have noticed that Impactful Ninja is all about providing helpful information to make a positive impact on the world and society. And that we love to link back to where we found all the information for each of our posts.
Most of these links are informational-based for you to check out their primary sources with one click.
But some of these links are so-called "affiliate links" to products that we recommend.
Why do we add these product links?
First and foremost, because we believe that they add value to you. For example, when we wrote a post about the environmental impact of long showers, we came across an EPA recommendation to use WaterSense showerheads. So we linked to where you can find them. Or, for many of our posts, we also link to our favorite books on that topic so that you can get a much more holistic overview than one single blog post could provide.
And when there is an affiliate program for these products, we sign up for it. For example, as Amazon Associates, we earn from qualifying purchases.
What do these affiliate links mean for you?
First, and most importantly, we still only recommend products that we believe add value for you.
When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.
And when you buy something through a link that is not an affiliate link, we won’t receive any commission but we’ll still be happy to have helped you.
What do these affiliate links mean for us?
When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.
When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).
And at this point in time, all money is reinvested in sharing the most helpful content with you. This includes all operating costs for running this site and the content creation itself.
What does this mean for me personally?
You may have noticed by the way Impactful Ninja is operated that money is not the driving factor behind it. It is a passion project of mine and I love to share helpful information with you to make a positive impact on the world and society. However, it's a project in that I invest a lot of time and also quite some money.
Eventually, my dream is to one day turn this passion project into my full-time job and provide even more helpful information. But that's still a long time to go.
Stay impactful,

📰 The quick summary: A powerful tidal turbine called the Orbital O2 has been deployed underwater and can generate enough clean energy to power 2,000 homes, offering a reliable alternative to wind and solar power.
📈 One key stat: The Orbital O2 system can produce up to 2 MW of clean energy per year, enough to power 2,000 homes annually, making it the most powerful tidal turbine in the world.
💬 One key quote: “An ocean of energy is patiently waiting for us to reach down into the sea and bring it to the surface to power our world.”

1️⃣ The big picture: As the world moves away from fossil fuels, renewable energy has grown rapidly over the past decade, with wind and solar leading the charge. However, a new player has emerged from beneath the ocean’s surface. The Orbital O2 is a tidal turbine system anchored to the ocean floor using four high-strength moorings, with most of its structure floating on the surface to keep installation costs low. It can generate up to 2 MW of clean energy per year, enough to power 2,000 homes, and sends that energy directly to the grid via a subsea cable. Recognized as the most powerful tidal turbine in the world, the Orbital O2 represents a major step forward for ocean-based renewable energy.
2️⃣ Why is this good news: Tidal energy offers something wind and solar cannot: consistency, since ocean currents are predictable and not subject to changing weather conditions. The Orbital O2‘s design keeps costs manageable by allowing most of the structure to float on the surface, making deployment far more practical than fully submerged systems. Sending power directly to the grid through a subsea cable eliminates the need for costly energy transport infrastructure. At 2 MW of output, a single unit can power 2,000 homes, meaning scaling up this technology could have a significant impact on national energy grids. Broader adoption of tidal energy could help reduce dependence on fossil fuels and shield communities from volatile energy prices.
3️⃣ What’s next: With the Orbital O2 now deployed and generating power, the focus shifts to scaling the technology and expanding tidal energy installations to new locations. Continued investment in ocean-based renewable energy will be key to unlocking its full potential. If costs continue to fall as the technology matures, tidal turbines could become a mainstream part of the global clean energy mix.
