Norway's Statkraft Looks at Power from Osmosis

Norway's Statkraft is looking at osmosis as a possible energy source.  Currently the output is minimal but it may be the way of the future.

" ... Norway's Statkraft says that its new, first-of-its-kind osmotic power plant could be producing as much energy as a small wind farm by 2015, ... when the process of osmosis takes place ... the pressure is apparently enough to drive a power generating turbine ... enough of those you have a power plant. A bit of effort, to be sure, but the process doesn't emit any greenhouse gases, is completely renewable, and it doesn't depend on the wind or the sun being out."
