Hydro Power

Using water as a power source has been achieved by Norway at a 100% even if they are giving the rest of Europe their oil. Besides Norway, such countries as Switzerland and Sweden seem to be leading the way in their use of thier resources. Hydro power is one of the oldest power resources we have and the tecnology that has gone behind it to make it more consumer useful hasn't stopped since its first use in irrigation wheels used to ground grain.
