If they move 3,000 blades for ~10MW turbines then a 20% improvement in capacity factor alone is worth 3,066,000 metric tons of CO2 year. Edit: (Ops 10Mw * 1,000 turbines * 0.5 tons from natural gas /MW * .35% capacity factor * 20% improvement * 24 * 365 hours, coal is roughly double that.)

By comparison a commercial jet takes ~20 years to emit 1 million tons of CO2. https://www.reuters.com/business/aerospace-defense/boeing-je...
