How Wave Power Could Be The Future Of Energy (youtu.be)

The ocean has an incredible amount of power potential. China’s brand new Wave Energy Converters has been making a lot of news recently. While this ocean power device isn’t the first of its kind, its sheer size represents a breakthrough for this underutilized but potent branch of the renewable energy family tree. What is wave energy generation, and how does it compare to other renewables like solar panels and wind turbines? And if wave energy is so great, then why is it lagging behind solar, wind and others? Let's dive into the ocean of renewable energy, where the waves may hold more untapped potential than the sun. Maybe the surfers were right all along.

ehhh, this, to my ignorant eyes, seems like a disturbance for the marin ecosystem.

Unlike evosystem in air and on land, many marian life travel purely by the flow of water. Harvesting these energy from water flow (on a large scale) can potentially change how these creatures flow, hence influence their preditors, which might change the local ecosystems.

On the other hand, this is not the first time we fuck with the ocean, and likely wont be the last. At least this is for a "good?" cause.

The amount of energy we'd need to pull from those flows even to power the full need of the world is likely pretty trivial compared to the amount those flows actually contain. Oceans are world engines, literally. There's a lot of energy in there.

These wouldn't prevent flows either, just leech a little and slow it down. Worth exploring.

The biggest issue is upkeep. Oil rigs require a massive amount of upkeep because salt water really wants to destroy most structural material, fast. Then you factor in costs of getting crews out there for maintenance, etc .. it adds up. Costs not just financially but in carbon as well. Material advancements help but you're back to the carbon costs with those in a big way too.
