Global Warming and our Changing World

I recently read that off the coast of Florida tons of water rushes by in a strong, smooth current, never pausing, never stopping. This energy can be harnessed with turbines, and would equate to 10 nuclear power stations, capable of supplying power to (I believe) 1/3 of Florida. What if we did that all over every continental coastline? What if we installed turbines throughout the majority of the ocean? We'd have tons of free, clean energy!

It seems like every couple of months, a new energy option is revealed. I'm starting to think we are fully capable with current technology of detaching from oil permanently. Let's hope we do it in time.
