Submerged in about 40 meters (44 yards) of water off Scotland’s coast, a turbine has been spinning for more than six years....

The MeyGen tidal energy project off the coast of Scotland has four turbines producing 1.5 megawatts each, enough electricity collectively to power up to 7,000 homes annually.

Not sure on the numbers, but in videos I've seen dozens of places where -all- the local power cud be tidally-generated, and I suspect there'd be hundreds of places around the world. Largely depends on the geology around the local tides.

    For sure, but meygen is way too big for most fast moving tide races. And most places that are deep enough don't have a fast enough current. The pentland firth is unusual in that it is both deep enough and has a current in the order of around 10 - 15 knots in places. It flows like a relatively fast moving river. It's not a normal stretch of water.
