According to CNN Money, there are four cutting edge ways to solve the "energy challenge", and one directly involves the ocean: turning seaweed into fuel.
Did you know that kelp, seaweed, is nearly 50% sugar? That's natural energy. Turning it into fuel is happening (in the lab) in Chile. Interesting stuff.
The other solutions are a longer range car battery, new fusion technology, and beaming electricity from space. Zap.
Meanwhile, an economist from Deustche Bank gives us the 4 point solution to the energy challenge:
1. Get rid of coal.
2. Ramp up gas as the transition fuel.
3. Hammer down the costs of renewables.
4. Focus on energy efficiency.
