The Snohomish County Public Utilities District recently launched a three-year study to evaluate the viability of seven tidal energy sites in the region and their potential electrical capacity. The study phase includes research to define actual tidal currents and to consider interconnections to the electrical grid.
How green is the Evergreen State? When it comes to using green energy, Washington is among the fastest growing states in the U.S., ranking No. 3 this year and trailing only North Dakota and Montana, according to the latest figures from the U.S. Department of Energy, which reported a 34 percent increase in renewable energy sources in Washington state during the first six months of 2007. Oregon ranked sixth among all states with nearly a 21 percent increase.
In Washington state, most of the growth comes from the major wind farms coming online along the Columbia River Gorge, in Kittitas County surrounding Ellensburg and in eastern Washington near the Tri-Cities and Walla Walla.
But the state's utilities are also investigating tidal, wave, solar, geothermal and biomass energy as they try to get 15 percent of their power to be green by 2020.
