I spotted this meme attacking wind farms on social media today: "Ponder this for a moment. The wind farm in Mt. Pulaski has been running for 3 1/2 years. They have been replacing the generators in all the wind towers. There are 100 of them in this wind farm. So evidently the life span on the generators on these things is about 3 to 4 years. It takes 12 semi trucks and trailers, a 9 axle 50,000 pound crane and 12 pickup trucks to change each generator. That is a huge amount of deisel fuel being used to maintain these wind towers. And the "Green groups" would like You to believe they are all fueled by magic fairy dust."
To set the record straight:
1) Wind turbines last 20 to 25 years, not 3 to 4 years as the meme indicates.
2) Zero generators had needed to be replaced on the Mt. Pulaski wind farm in its 3 and 1/2 years of operation. Zero. Instead 17 gearboxes were switched out due to defects.
3) Maintenance is required about twice a year, with all important mechanical and electrical assemblies being checked. The oil does, indeed, need to be changed.
4) Wind farms do not release any emissions, and since it is emissions that are causing climate change, wind turbines are not contributing to that. If we want to fight climate change, wind farms are one of our best power alternatives.
