Clean water, cleaner energy: Penn State powering renewable energy technologies

UNIVERSITY PARK, Pa. — Among renewable sources of energy, humans have long recognized the power of water. At the places where freshwater and saltwater meet, for example, there are vast amounts of potential energy to be tapped — enough, in theory, to supply 40 percent of global electricity needs.

The process is called salinity gradient energy, and it’s a new area of focus for environmental engineer Bruce Logan. But it’s also a continuation of the work he’s been doing at Penn State for 20 years.
