Nationwide the use of hydro electricity is declining.
The design of turbines have not improved greatly over the past 100 years.
The research on hydro plants is vast, and the promise of improvement may not be there.
Yet, the government still has many departments created to further development of hydro power.
Still, in places where there is a lot of flowing water, or in remote areas that are harder to wire for electricity the use of water could still be an asset.
