Hydropower dams: Relationships

Every element and industry that Hydropower dams is linked to, and how. Each pair has its own card explaining the relationships between the two.

• Water: A dam's output is set by how much water reaches its reservoir, so a weak monsoon or a drought cuts generation and forces coal or gas to fill the gap. Reservoirs also lose water to evaporation and share it with irrigation and cities, which ties hydropower to water policy. (researched)
• Generators and alternators: Energy flows from hydropower dams to generators and alternators; their prices have moved together.
• Natural reservoirs: Energy flows from hydropower dams to natural reservoirs; energy flows from natural reservoirs to hydropower dams.
• AC transmission: Energy flows from hydropower dams to AC transmission.
• Cement: Their prices have moved together.
• Construction chemicals: Their prices have moved together.
• Natural gas: Their prices have moved together.
• Pumped hydro storage: Energy flows from hydropower dams to pumped hydro storage.
• Steel: Their prices have moved together.
• Water cycle: Energy flows from water cycle to hydropower dams.
