Concrete spheres offer possibility of storing offshore wind turbine energy

The video explains how offshore wind farms can be enhanced using giant concrete spheres. These spheres are used to pump seawater when wind turbines are not generating power. By filling with seawater, the spheres turn a turbine connected to the power grid, thus maximizing energy production. This innovative approach helps in storing and utilizing energy efficiently.

What is the primary function of offshore wind farms as described in the video?

• To pump seawater out of concrete spheres

• To generate solar energy

• To desalinate seawater

• To store natural gas

What happens to the concrete spheres when wind turbines are not producing power?

• They remain empty

• They release stored energy

• They generate solar power

• They fill with seawater

How do the concrete spheres contribute to energy production?

• By storing solar energy

• By turning turbines connected to the power grid

• By acting as a battery

• By converting seawater into hydrogen

What is the ultimate goal of using concrete spheres in offshore wind farms?

• To maximize energy production

• To desalinate seawater

• To increase fish population

• To reduce carbon emissions

Which of the following is NOT a function of the concrete spheres?

• Maximizing energy production

• Generating solar power

• Turning turbines

• Filling with seawater
