Environmental Impacts of Hydropower

The U.S. Department of Energy points out several negative impacts of hydropower.  Most of these impacts do not apply to the Lower Sunshine Reservoir Project due to the fact that the dam is off channel.  The one factor that does apply to this project is injury to fish.


The Department of Energy has developed four turbine designs to limit the damage to fish passing through the turbine.  One turbine design uses technology used in the food processing industry.  This design can be seen in the picture below.

I applaud the desire to be environmentally friendly, but I also see a potential for taking it too far.  We have to solve our energy problems, and yes, a few fish will be lost in the process.  I think these fish families would be proud that their loved ones gave their life in service to their country.
