Wind Energy

Question 1

What % of global energy is derived from wind?

Answer 1

less than 1%

Question 2

What is the potential of wind energy compared with current global consumption

Answer 2

Potential to provide 200 times GPEC

Question 3

Give 4 arguments for wind energy

Answer 3

• Clean and sustainable energy source
• Saves land and land around the turbine can be used for agriculture or recreational purposes
• In the UK, demand is greatest during winter, and wind is stronger, so wind can match demand
• In the UK, we are in an exposed position so wind speeds are strong enough the majority of the time

Question 4

Give 4 arguments against wind energy

Answer 4

• Can be noisy, but new blade designs reduce the noise
• Windspeed varies so energy not continually produced
• Visual impact, especially as often in rural locations
• Wind power can’t increase or decrease its output to match demand
