Kaplan Turbines
+Blades can be rotated to allow for variations in water flow
+They can harness up to 90% of the kinetic energy of flowing water
-
Helical turbines
-
-
+High efficiency.
+Can use water with a high turbidity without being damaged. +Provides almost all the electricity for Windsor Castle.
+Fish can be carried down the turbine without being damaged.
Micro hydro schemes
These are small schemes used by rural areas. They divert the water away from the river and over turbines this means the river flow is slowed for a portion but fish can still migrate. The water then gets pushed back into the river.

Features
As water flows from one reservoir to another, potential energy is converted to kinetic energy, and then to electrical energy when it turns the turbine.

-
71% of all renewable energy is supplied by HEP.
It provides nearly 20% of the world’s electricity across the world.
