Wind Energy

Wind is what type of energy?

• Renewable

• Non-Renewable

Answer explanation

Wind energy is classified as renewable because it is generated from natural processes that are continuously replenished, unlike non-renewable energy sources such as fossil fuels that can be depleted.

A Wind Turbine have a large propeller wheel rotated by the wind to generate electricity.

• True

• False

Answer explanation

A wind turbine consists of a large vaned wheel that rotates when wind blows, converting kinetic energy into mechanical energy, which is then used to generate electricity. Therefore, the statement is true.

An area of land with a group of energy-producing windmills or wind turbines

• Windmills

• Wind Farm

• Wind Turbines

• Generators

Answer explanation

A 'Wind Farm' is specifically defined as an area with multiple wind turbines or windmills that produce energy. While 'Windmills' and 'Wind Turbines' refer to individual units, 'Generators' do not specifically denote the grouping of these energy producers.

What changes wind energy into electricity?

• Windsock

• Wind Turbine

Answer explanation

A wind turbine converts wind energy into electricity by using its blades to capture wind movement, which spins a rotor connected to a generator, producing electrical power. A windmill primarily serves mechanical purposes, not electricity.

How do wind turbines affect the environment.

• Can harm birds and other wildlife

• Cuts the clouds which affects the water cycle.

• Hits trees around them

• They are perfect for the environment.

Answer explanation

Wind turbines can harm birds and other wildlife due to collisions with the blades. This impact on wildlife is a significant environmental concern, making the first answer choice the correct one.

What is the name of part A in the wind turbine above?

• Blade

• Gear

• Generator

• Axle

Answer explanation

Part A in the wind turbine is called a Blade. Blades are crucial for capturing wind energy and converting it into rotational motion, which is essential for the turbine's operation.

The diagram above shows a wind turbine. Which section of the wind turbine converts wind energy to electrical energy?

• blades

• generator

• rotor

• pitch system

Answer explanation

The generator is the component of the wind turbine that converts the mechanical energy from the rotor, driven by the wind through the blades, into electrical energy. Thus, the correct answer is the generator.
