What is the primary source of energy for tidal power?

  1. Sunlight

  2. Wind

  3. Tidal currents

  4. Fossil fuels


Correct Option: C
Explanation:

Tidal power harnesses the energy from the movement of tidal currents, which are caused by the gravitational pull of the moon and sun on the Earth's oceans.

What is the most common type of tidal power plant?

  1. Barrage

  2. Lagoon

  3. Dynamic tidal power

  4. Tidal stream generator


Correct Option: A
Explanation:

Barrage tidal power plants are the most common type, consisting of a dam or wall built across an estuary or bay, creating a reservoir that fills and empties with the tide.

How does a barrage tidal power plant generate electricity?

  1. By capturing the kinetic energy of tidal currents

  2. By converting the potential energy of the water in the reservoir

  3. By using turbines to generate electricity from the flow of water

  4. All of the above


Correct Option: D
Explanation:

Barrage tidal power plants utilize the potential energy of the water stored in the reservoir during high tide, which is then released through turbines to generate electricity as the tide ebbs.

What is the main advantage of tidal power over other renewable energy sources?

  1. It is a predictable and reliable source of energy

  2. It does not require large amounts of land

  3. It has a low environmental impact

  4. All of the above


Correct Option: D
Explanation:

Tidal power is a predictable and reliable source of energy due to the consistent nature of tides. It also requires relatively small amounts of land compared to other renewable energy sources and has a low environmental impact.

What is the main disadvantage of tidal power?

  1. It is a relatively expensive technology

  2. It can only be generated in coastal areas

  3. It can disrupt marine ecosystems

  4. All of the above


Correct Option: D
Explanation:

Tidal power technology is still relatively expensive compared to other renewable energy sources. Additionally, tidal power plants can only be built in coastal areas with strong tidal currents, and they can potentially disrupt marine ecosystems if not properly designed and operated.

What is the potential global capacity of tidal power?

  1. 100 GW

  2. 1,000 GW

  3. 10,000 GW

  4. 100,000 GW


Correct Option: D
Explanation:

The potential global capacity of tidal power is estimated to be around 100,000 GW, which is significantly higher than the current global electricity demand.

Which country has the largest installed capacity of tidal power?

  1. China

  2. United Kingdom

  3. France

  4. South Korea


Correct Option: A
Explanation:

China has the largest installed capacity of tidal power in the world, with several large-scale tidal power plants in operation.

What is the largest tidal power plant in the world?

  1. Sihwa Lake Tidal Power Station

  2. Jiangxia Tidal Power Station

  3. La Rance Tidal Power Station

  4. Annapolis Royal Generating Station


Correct Option: A
Explanation:

The Sihwa Lake Tidal Power Station in South Korea is the largest tidal power plant in the world, with a capacity of 254 MW.

What is the main challenge facing the development of tidal power?

  1. High cost of construction

  2. Environmental concerns

  3. Lack of suitable sites

  4. All of the above


Correct Option: D
Explanation:

The development of tidal power faces several challenges, including the high cost of construction, potential environmental impacts, and the limited number of suitable sites for tidal power plants.

What are some of the potential environmental impacts of tidal power plants?

  1. Disruption of marine ecosystems

  2. Changes in sediment transport patterns

  3. Increased erosion

  4. All of the above


Correct Option: D
Explanation:

Tidal power plants can potentially disrupt marine ecosystems by altering water flow patterns, changing sediment transport patterns, and increasing erosion.

How can the environmental impacts of tidal power plants be minimized?

  1. Careful site selection

  2. Proper design and operation of tidal turbines

  3. Environmental monitoring and mitigation measures

  4. All of the above


Correct Option: D
Explanation:

The environmental impacts of tidal power plants can be minimized through careful site selection, proper design and operation of tidal turbines, and the implementation of environmental monitoring and mitigation measures.

What is the future of tidal power?

  1. Tidal power is expected to play a significant role in the global energy mix

  2. Tidal power is likely to remain a niche technology

  3. The future of tidal power is uncertain

  4. None of the above


Correct Option: C
Explanation:

The future of tidal power is uncertain, as it depends on a number of factors, including technological advancements, cost reductions, and the development of policies that support the development of renewable energy sources.

What are some of the promising developments in tidal power technology?

  1. Development of more efficient tidal turbines

  2. Floating tidal turbines

  3. Tidal lagoons

What are some of the challenges that need to be addressed for tidal power to become a more widely adopted technology?

  1. Reducing the cost of construction

  2. Addressing environmental concerns

  3. Developing more efficient tidal turbines

  4. All of the above


Correct Option: D
Explanation:

There are several challenges that need to be addressed for tidal power to become a more widely adopted technology, including reducing the cost of construction, addressing environmental concerns, and developing more efficient tidal turbines.

What is the role of tidal power in the transition to a clean energy future?

  1. Tidal power can play a significant role in reducing our reliance on fossil fuels
