Wind Power

The video explains how wind is generated by air movement around the equator and its historical uses in sails and windmills. It then describes modern wind turbines, which convert wind energy into electricity without waste. Despite their potential, wind turbines face challenges such as unpredictability and aesthetic concerns. Offshore turbines offer solutions but are costly. Wind power, while not a complete solution, is a clean, renewable resource that could significantly contribute to sustainable energy in the future.

What natural phenomenon causes the formation of wind around the equator?

• Intense heat causing warm air to rise

• The rotation of the Earth

• Ocean currents

• The gravitational pull of the moon

How do modern wind turbines generate electricity?

• By burning fossil fuels

• By using nuclear reactions

• By converting kinetic energy into electrical energy

• By using solar panels

What is the relationship between the length of turbine blades and electricity generation?

• Blade length does not affect electricity generation

• Shorter blades generate more electricity

• Blades do not play a role in electricity generation

• Longer blades generate more electricity

Why is wind power not more widely used despite its potential?

• It is not a renewable resource

• It produces a lot of waste

• Wind is an unpredictable force

• It is too expensive to maintain

What is one advantage of offshore wind turbines?

• They can be placed anywhere

• They require less maintenance

• They solve some noise and aesthetic issues

• They are cheaper to set up
