Last week, Governor Brad Henry signed a legislation requiring that Oklahoma generate 15% of its electricity through renewable energy sources by 2015. The legislation counts hydropower in its renewable portfolio along with wind, solar, photovoltaic, hydrogen, geothermal, and biomass.
The Low Impact Hydropower Institute (LIHI) has certified three more projects that meet their low-impact certification criteria. The three projects are Winooski in Vermont, Farmers Irrigation District in Oregon; and the Robertson and Ashuelot in New Hampshire.
Through the certification, LIHI recognizes that these projects have avoided or reduced their environmental impacts as required in their certification process.
