Summary: One of the simplest forms of energy generation is to have a floating buoy on the sea surface. While different companies have come up with different ways to use the up and down motion of the waves to create energy, we'll highlight here the OPT buoys. The up and down movement of these buoys help turn a turbine, which generate electricity. This electricity is then sent to substation underwater, which is the then sent to grid onshore. One benefit is that the buoys can be set out and pulled in with minimal cost. The big news with energy buoys is that they represent the first wave energy devices available for commercial energy manufacture in the united states. In fact, along the coast of Oregon, the government has issued a permit for 10 energy buoys that should be enough to generate electricity for 1,000 homes.
