Hydropower and ocean energy
Traditional hydropower systems have been in use for hundreds of years as a source of energy for a wide variety of mechanical applications. As such, hydropower represents a renewable energy source that has been successfully used for a long time. Since the beginning of hydropower-generated electricity, the percentage of electrical energy generated in this way has grown to around one quarter of all the electricity used worldwide.
