M. mcchambin, I notice your tidal French "Rance Projet" is a mere 240 MW. 😱
As a man with his finger on the pulse, I notice a modest modern 16 x 15 MW British wind turbines can match this. 😀
I hadn't really considered the effects of our wind-turbines, with a tip speed of 300 Km/pH stunning passing birds. But have solved it. 😎
The solution to Global warming lies in the disputed UK Island of Rockall:
Tidal power to the max. Evidently windy and perfect for our turbines. Just need the power cable. I amaze myself sometimes. The Puffins must be considered expendable in these terrible times. If the Irish or Icelanders claim it, we must regrettably send a gunboat. How it is. 😱

You've made good use of the Rockall images that I've previously posted, Steve!
I'm all for recycling, but your version takes up so much space! 😀

Re extracting energy from ocean currents:
Ocean Current | Tethys
Ocean Current | Tethys
Strong ocean currents tend to be further offshore than tidal currents, which tend to be found in coastal or inland waters. This leads to deployment in deeper water. As ocean currents are strongest higher in the water column, fixed substructures for supporting a turbine become impractical for harnessing ocean current energy. Instead, devices may be suspended from moored surface platforms or attached to buoyant structures tethered to the seabed. Electricity is produced from the ocean currents by coupling a generator to the turbine and power is transmitted back to shore via subsea cable.

P.S. The link suggests that the development of underwater turbines may not be good news for whales and dolphins! 😱
You cannot generate energy without collateral damage of some kind. You either live in a cave, scratch out a living burning a bit of dry wood with minimal impact on the environment, or you evolve, civilize and leave a mess in your wake.
200 000 yrs ago, we started out on this journey. I just hope mankind will be here in 200 000 yrs

Here's a comment from phys.org that was made just three years ago:
New technologies in the ocean energy sector"It still takes a level of almost science fiction fantasy to imagine that we can use the oceans' permanent movement to power our cities and houses."
And that we survive the next ice age, which man-made global warming is helping to delay till 100,000 years from now!I just hope mankind will be here in 200 000 yrs 🙂

I was listening to the Midnight MasterMind last Night on BBC Radio 2.
Some Northern Lass called Sonja felt the need to phone up the resident meteorolgist DJ and ask him some clearly difiicult questions about the Solar System. Launched into some RAP that she had seen a Planet last night. "It were AMAZING" quoth she. 😕
I immediately detected she were some relative of Professor Brian Cox...
Anywhoo, here's her questions:
1: "Which Planet is the LARGEST in the Solar system?"
2: "Which Planet is the HOTTEST in the Solar System?" (Launched into some rant about greenhouse Gas and Global Warming...)
3: "Which Planet has SUPERSONIC Wind Speeds?"
I didn't get the last one right. She's a bright lass. 😱

I have sometimes listened to OJ Borg, but not so much now that Radio 2 seems to have adopted a policy of not playing my favourite old tracks.I was listening to the Midnight MasterMind last Night on BBC Radio 2.
As for the answer to the third question, I read that there are supersonic methane winds on Neptune, with speeds reaching 1200 mph!

Ah - but that was three yrs ago!
The sun is still the best bet.
1000W per square meter at the surface of the earth perpendicular to the suns rays. We need 80-90% solar cells. There's a challenge for you @steve
😀
Here's another idea. We tie a large steel rope between the earth and the moon. Since the moon's orbit is not exactly circular, but slightly elliptic, when it moves away, we can use it to LIFT say 10-15 billion tons of water in a large bucket.
You place electricity generation turbines around the bottom of the bucket, so that as the water drains out, the turbines are rotated, thus generating electricity.
Advantage: completely green
Simple. Effective. Pure genius. Almost as good as Bybees

Absolutely! There was a guy on Dragon's Den a few years ago flogging the notion of giant concrete slabs on a reciprocal generator that via a geared mechanism generates power in both directions as it is moved back and forth by the current (think of a blanket draped over a clothes line).Have you any info on practical schemes to extract energy from ocean currents, Pete?
I'll try to examine the possibility later.
They actually acted as if they couldn't understand what the guy was talking about as if deliberately avoiding to even respond. Weirdly curious. 
But why out? Could that not work?

It could work as well as any other proposed system, but I am in no place to judge.
The investment of money, even to build a working experimental model, would surely be more than even the richest Dragon would be prepared to make.
Or, are you going to tell me that one of them took on the challenge?

Wait a minute, doesn't an ocean current flow in only one direction?...generates power in both directions as it is moved back and forth by the current.
You must be describing a wave energy generator - not an ocean current energy generator!

Yes, wave energy.
No, but they did allude to the realm of govt. fiscal expenditure. An indication of why their coy/dismissive attitude.

If we are using wind energy then aren't we using earth's spin energy . Conservation of energy suggest earth will slow down . If yes
