Alternative Energy Examples FAQs
How do tidal power plants function, and where are they commonly found?
Tidal power plants function by harnessing the energy created by the rise and fall of ocean tides. Here’s how they work:
Tidal Flow: Tidal power plants are typically located in coastal regions with strong tidal currents. As the tide rises and falls, water flows in and out of estuaries or bays.
Turbines: Underwater turbines or tidal stream generators are placed in these tidal flow areas. These turbines resemble underwater wind turbines.
Generating Electricity: As water flows past the turbines, they spin. Converting the kinetic energy of the moving water into mechanical energy. Which is then transformed into electrical energy through generators.
Tidal power plants are commonly found in regions with significant tidal ranges. Such as the Bay of Fundy in Canada, the Pentland Firth in Scotland, and La Rance in France. These areas experience strong tidal currents, making them ideal locations for harnessing tidal energy.
What is the role of water reservoirs in hydroelectric dams?
Water reservoirs play a pivotal role in hydroelectric dams by acting as energy storage and flow regulation systems:
Energy Storage: Water is stored in the reservoir at higher elevations when there is excess electricity generation. Typically during periods of low energy demand or when renewable energy sources like wind and solar are producing surplus power.
Flow Regulation: When electricity demand is high, or when the grid needs more power, the stored water is released from the reservoir and allowed to flow downhill through turbines.
Turbine Operation: As the water flows downhill, it passes through turbines, converting the potential energy of the falling water into electricity. The controlled release of water from the reservoir ensures a steady and reliable power supply.
Water reservoirs in hydroelectric dams provide a way to balance electricity supply and demand, making hydroelectric power a flexible and responsive energy source.
How does hydroelectric power compare to other alternative energy sources?
Hydroelectric power has its unique characteristics and advantages compared to other alternative energy sources:
