A reader notes:
While I am a huge supporter of ocean wave and tidal energy, I adamantly oppose messing with ocean currents. Water follows the path of least resistance, so it’s very easy to disrupt current patterns that have countless species relying on the stable weather patterns they produce. If Florida taps the ocean current and the warm waters don’t make it to the northern Atlantic coast anymore, then what?
Well, how much of the total ocean current do you think we’re trying to slow down? It’s infinitesimal.
There is a senator who is against wind energy because he’s worried about what slowing down the wind will do to the planet. Same deal.
Having said all this, there is no chance whatsoever that ocean current can compete on price again solar and wind; that’s an even better reason not to worry.
