Where I live, nearly half the electricity is from hydroelectric sources. And by the way, rivers and lake egress points are the primary sources of hydroelectric power, not the sea. Who gave someone THAT idea? How bizarre! And my home has both wind and solar supplemental power.
Reality: if population continues to grow, we have no option but to use ALL available means to generate, and of course, likewise, to improve
overall energy efficiency.
This whole thing is generally misstated, anyway, by political slime and hacks looking to stir controversy and spread confusion. Wind, solar, geothermal will be supplements to other means for quite some time, especially wind and solar, which are intermittent. Hydroelectric power is clean and efficient, and is wellspring, and we've been using it up here for most of this century.
That doesn't mean any other means is replaced or "off the table".
