watch the documentary "dam nation"  it was on one of the internet subscriber services.  blowing a dam is a beautiful thing - in a moment that moving water begins to heal the earth and allows it to fix itself.  the owyhee  river basin...before the dams, and again ,now , with the dams removed?  spectacular.  
 source for electricity?  another challenge -  another place.  it's a commodity with different options and personally I like solar, wave and wind energy.  I wouldn't mind having a 2016 model, super efficient, latest and best windmill on or next to my house.
