Wind Energy is...

 Energy that comes from harnessing the movement of the air

Ultimately derived from the sun because it is the cause for moving fluids on the planet.

A source of renewable energy, such as solar, wind, or geothermal energy

Not sufficient in all areas of the planet so as to be practicable

Answer explanation

Wind Energy is energy that comes from harnessing the movement of the air, ultimately derived from the sun, making it a source of renewable energy like solar and geothermal energy.

What is the force that occurs when an abject is moving in-line with the fluid?

Thrust force

Lift force

Drag force

Gravitational force

Answer explanation

When an object is moving in-line with the fluid, the force that occurs is known as drag force, which acts opposite to the direction of motion.

Why are turbine blades placed at certain distance in front of the tower in horizontal axis wind turbines?

To prevent energy loss by the drag force

To prevent the blades from hitting the ground

To prevent the blades from being pushed into the tower

To prevent the blades from falling off

Answer explanation

Turbine blades are placed in front of the tower to prevent them from being pushed into the tower, ensuring safe operation.

Media Image

What is one advantage of a vertical axis wind turbine over a horizontal axis wind turbine?

It can harness winds from every direction without the need to reposition the blades or hub.

The blades are closer to the ground where the wind speed is higher.

They are capable fo generating more power per turbine.

The mechanical components are high off the ground so they don't have to be serviced periodically.

Answer explanation

A vertical axis wind turbine can harness winds from every direction without the need to reposition the blades or hub, giving it an advantage over a horizontal axis wind turbine.
