Where do most people live? Near coastlines. And this is true world-wide. Something like ( don't quote me ) 75% of all people live less than 100 miles from an ocean.

When people talk about natural energy ( sun, wind, hydro ) no-one mentions TIDAL energy. There will always be tides, and they ( while they have peaks and valleys) run 24/7.

99% of the people out there will agree hydro-electric from dams, etc is a good thing. Hoover Dam ( near Las Vegas ) powers all of Vegas ( cheaply ) and most of Los Angeles as well! And it has run for 75 years, and will last for 100's of years.
That's good ol' over engineering at work!

Along coastlines, you build tidal dams. Sure, you have fewer feet of "head" but you have an unlimited # of gallons of water. And you generate power at high tide when the water rushes in, and you generate at low tide when water rushes out. During the "mid-point" when you have your reservoir at the same level as sea level, you are screwed, right? WRONG!

During off-peak hours, when you have excess generating power, you use some power to PUMP water uphill to an above sea-level reservoir. During times of "non-tide" or peak demand hours, you tap your elevated reservoir.

This is simple, proven technology. We just need the legislation to do projects on a grand scale... like in the days of Hoover Dam. We need a governmental action, such as the CCC or WPA of days long past, as no single corporation could tackle such a huge undertaking. Once built though, it would last generations. Then you have cheap, near unlimited electricity, and EV's become reality.
