Advantages and Disadvantages
Name 1 environmental or ecological advantage of Wind Farms.
Wind is renewable resource
Does not release any carbon emissions contrary to burning fossil fuels
Does not cause ecosystem threatening disasters
Does not emit any toxic substances or contaminants
Many areas have regulations that limit wind turbine noise at the nearest residences to __ dB.
40 dB
What is the minimum distance that a wind turbine can have from a noise receptor?
550m
How much does a typical turbine cost?
$ 2-4 million
What is one thing being added in newer wind turbines just in case the noise produced by them is causing health effects?
Sound-dampening systems, Quieter Gears & Generators, Insulated Housing, Noise-Mitigating Blades
What are the two main consultation and environmental approval processes?
REA and EA
Name 2 environmental or ecological disadvantages
It takes 6 months to 1 year to generate the amount of energy required to build the wind turbine in the first place
Only Viable in regions with consistent and strong winds
True or false: Wind turbines and farms do emit an amount of EMFs that can threaten human health.
False
What are 2 examples of a noise receptor?
Schools, residences, libraries, hospitals, and other care facilities
Approximately how many wind technician jobs are created every year.
150 Jobs
What is shadow flicker?
Occurs when the blades of turbines rotate in sunny environments, creating moving shadows on the ground. Results in light appearing to be flickering on and off.
What are the three main requirements of the REA regarding large wind energy projects?
Noise limits based on a 40 decibel noise guideline.
At least 550 meters from homes and buildings,
Setbacks from property lines, public roads and railways.
What is the relation between wind farms and carbon dioxide emissions that was deduced in the research of this presentation?
Explain Briefly.
The number of wind projects are indirectly proportional to carbon dioxide emissions.
Even though wind power does not directly affect the amount of carbon dioxide emissions that there are, it leads to less fossil fuels being burnt because electricity generated by wind power is preferred.
How many meters can entire blades be thrown during turbine blade failure? How many meters can blade fragments be thrown during blade failure?
150 m, 500 m, respectively
How many public meetings are required under the REA.
