Waterpower TechnologiesConventional HydropowerDamHeadTurbinesSpillway

Pumped StorageUpper and lower reservoirsPumps/turbinesA twist, but high value

Waterpower Technologies

HydrokineticTidal/Wave/LockVelocity component of Bernoullis equationSmall energy output relative to conventional because of no head (except for lock application)Value in use of arrays and as components of meeting Renewable Portfolio Standards

Waterpower Technologies

We have impacted our landscape in many ways, including virtually all riversWe cannot revert to pristine conditionDam removal many should go butCost of compliance with agencies and special interest demands very high costs come back to youAncillary benefits of hydro no other industry comparesFacts of the Matter23,000 MW could be developed by 2025 without building a single new damIn many (if not most) cases, fish restoration targets are overly optimisticLicensing/Relicensing Costs, Time, and Uncertainty
