How to Grease a Windmill
Wind turbines and wind machines have enjoyed a resurgence as of late due to rising power costs and an increased consciousness of green energy. Wind turbines are effective energy generators and can produce substantial amounts of power over the course of many years. As there are many moving elements involved in wind turbines, some minor maintenance is required to ensure the longevity and power output levels. Minor maintenance such as greasing will extend the life of your backyard turbine. Does this Spark an idea?

Tips & Warnings
On large-scale wind turbines, which employ adjustable pitch blades, apply grease in the same fashion to these bearings, located at the foot of the rotor blades.
Always ensure your ladder or scaffolding is sturdy and safe before climbing.
