La energía hidráulica

The video discusses hydropower as a leading renewable energy source, highlighting its three main types: dams, tidal, and wave energy. Dams are the most common, providing water and reducing flood risks but impacting ecosystems. Tidal energy uses underwater turbines, while wave energy employs converters. Both are costly but offer minimal operational expenses. Hydropower is less ecologically invasive and holds promise for future energy needs.

Which of the following is NOT a main source of hydraulic energy?

• Solar

• Wave

• Dams

• Tidal

What is one of the primary benefits of dams in hydropower generation?

• They provide water to arid regions.

• They require no maintenance.

• They do not affect local ecosystems.

• They are inexpensive to build.

How do tidal energy systems generate electricity?

• By capturing solar energy

• By using wind turbines

• By harnessing the kinetic movement of ocean tides

• By burning fossil fuels

What is a disadvantage of tidal energy systems?

• They are unpredictable.

• They are inexpensive to build.

• They have high operating costs.

• They can damage ecosystems.

What is a characteristic of wave energy parks?

• They are the most ecologically invasive.

• They capture energy from the rise and fall of waves.

• They have high operating costs.

• They are cheap to connect to the main grid.
