NY Proposes Recycling Cooling Water at Nuclear Power Plants
Posted on Mar 24, 2010 by Jennifer Lance.
When one thinks of nuclear power, images of cooling towers rising into the sky come to mind. Water is needed in nuclear power production in order to cool the “waste heat” generated and in case an accident occurs. The Union of Concerned Scientists explains:
For every three units of energy produced by the reactor core of a U.S. nuclear power plants, two units are discharged to the environment as waste heat. Nuclear plants are built on the shores of lakes, rivers, and oceans because these bodies provide the large quantities of cooling water needed to handle the waste heat discharge.

1.5 Megawatts of Wave Power Coming to Oregon
Posted on Dec 08, 2009 by Jennifer Lance.
The first phase of an Oregon wave power project off the coast of Reedsport has begun with the contract award to build the first PowerBuoy. This project is the”first commercial wave energy PowerBuoy® system in North America”, and eventually 10 buoys will be brought online. One buoy will produce 150 kilowatts and create 30 jobs, according to Business Wire, and the first one will be brought online 2010.

Venice to Use Algae in Canals for Emissions-Free Power by 2011
Posted on Apr 10, 2009 by Jennifer Lance.
Nicknamed the “City of Water”, Venice, Italy is world famous for its canals. In fact, the city is practically a “no car zone” since it is built upon water. Unfortunately, this water is plagued by algae (Sargassum muticum and Undaria pinnatifida) that was brought to the seaport from Japan, China, Korea, and France. The algae poses problems for Venice’s famous gondolas and ferry boats, but now the city is looking at a unique solution to the problem: convert the algae into energy!
