We were pretty excited about Pelamis’ wave power plan in Portugal., but not every technology written about here pans out in the end. Pelamis’ €9 million Aguacadora wave power project–the world’s largest–has been taken offline due to numerous technological and financial setbacks.

The planet’s 44 million servers actually use 0.5% percent of the world’s electricity. If you total up data centre emissions, one guesstimate is that they are close to the same level as carbon output of nations such as Argentina.

In the U.S. we hear a lot of talk about wind and solar power, but considerably less about wave power. Wave power is simply using the power of the ocean to generate electricity. Well, it’s not quite that simple…

Professor Stephen Salter at the University of Edinburgh, Scotland, began the first modern experiments with wave energy in the 1970s. His invention, called Salter’s Duck is still considered to be the most efficient wave energy technology
