Well this should be fun:
Wind power is the ultimate waste. There is no possible way it recoups investment.
The upfront investment can be substantial—a single 3.5 MW commercial turbine costs over £3.13 million to build. However, those turbines can generate between £2.79 million and £7.1 million per year in revenue. Source
Strike One.
solid metal center column that is encased in composites (fiber glass or carbon fiber). The blades are composites too. They cannot be recycled and are replaced every 7~10 years, with the old ones going to landfills.
Here's an article on the US DOE's own web site about advances in recycling turbine blades and composites.
Strike Two.
Farmers have to move fences and restructure farms to allow the trucks to enter.
I've heard of farmed salmon, but I don't think that's what you are referring to. These are OFFSHORE wind farms. No farmers, no fences, no trucks. Please stay on topic.
Each turbine takes 300 gallons of oil!
Jumpin Jesus! Holy cow!
How many gallons of oil does a coal plant use for lubrication and all the diesel equipment to move coal around, and move the waste ash around? How many gallons of oil does a diesel generator use over it's lifetime, and how many kW of energy does it create with substantially more oil used?
THE TURBINE DOESN'T BURN THE OIL TO MAKE ENERGY. You apparently know this, since you hinted that it's used for cooling. It's not used in evaporative cooling, so that same 300 ga. of oil will be there until the decommissioning of the turbine.
Strike Three.
You then go on to make a bunch of baseless assumptions that are loosely correlated to the above, which I've already shown to be monumentally stupid.
