EcoAlert: Wave Power Delivers Electricity to US Grid For First Time

20100928-power-buoy-oahu While wave power often seems like the poor cousin of the renewable energy world, and frankly doesn't have the practical potential of wind or solar power, tapping the power of the sea does have its place and this next one is worth a bit of hand clapping: One of Ocean Power Technologies' PowerBuoys can claim to be the first wave power device to deliver electricity to the US grid.

The PowerBuoy was deployed three-quarters of a mile off the coast of Oahu last year and has produced power for more than 4,400 hours of operation. As for environmental impact, independent evaluation has found the PowerBuoy to have no significant impact. All good news, if a small step forward.
