Undersea kites generate tidal energy in Denmark’s Faroe Islands
It often tends to be forgotten, but solar energy has a twin - renewable lunar energy - harnessing the power of the tides. Not everywhere in the world is suited to it. However, this company says there's enough of it to meet 10% of global electricity demand. Some places are especially well suited,, and they point out Alaska could get 100% of its electricity from tidal power.
Every region will have renewable/clean energy that is better suited to it. Investing in many approaches and deploying them where they're most effective is definitely the right approach. Alaska would be terrible for solar, but I imagine this solution wouldn't have anywhere near the amount of seasonal fluctuation. My only concern would be the potential effects on marine life, though I'm sure it would be far less than the heating and accidification of the oceans due to emissions.
Not as terrible as you'd think, but worse in winter. Would be well complimented by something like this.
But I wonder, how about rivers without damms?
That is heckin' cool
