Five Facts - Hydro Power

The video explores five fascinating facts about hydropower. It begins with the historical use of hydropower for over 5,000 years, initially for machinery rather than electricity. The role of gravity in hydropower generation is explained, highlighting how water flow and speed contribute to energy production. The video also discusses various sources of hydropower, including rivers and small turbines, not just large dams. Norway's significant reliance on hydropower is examined, noting its geographical advantages. Finally, the environmental impact of hydroelectric dams is addressed, with solutions like fish ladders and elevators to aid fish migration.
