Understanding Wind Energy

Wind is a renewable resource that can generate electricity through wind turbines. It is efficient, affordable, and has a low environmental impact. However, effective wind energy requires consistent winds, which are not available everywhere. Despite some challenges, wind energy is a viable option for the 21st century, with the potential for industrialized countries to meet 25% of their electricity needs by 2025.

What is the primary function of a wind turbine?

• To store wind energy

• To convert wind into heat

• To generate electricity

• To measure wind speed

Which of the following is NOT an advantage of wind energy?

• Relatively affordable

• Low environmental impact

• Highly efficient

• High environmental impact

Why is it important for wind farms to be located in areas with consistent winds?

• To increase the lifespan of turbines

• To ensure effective energy generation

• To reduce noise pollution

• To minimize maintenance costs

What percentage of electricity needs could potentially be met by wind power in industrialized countries by 2025?

• 10%

• 15%

• 25%

• 50%

Despite its shortcomings, why is wind energy considered a viable option for the 21st century?

• It requires no initial investment

• It has the potential to significantly contribute to electricity needs

• It can be used in all parts of the world

• It is the only renewable energy source
