Useful overview of the progress of #wind energy techno-economics:

If developers can show that wind turbines have a long lifetime, financiers will be more inclined to advance loans for longer periods, possibly with favourable interest rates. The lifetime of a plant has a strong influence on the generation costs of wind energy. A wind farm with capital costs of $1,600/kW would deliver electricity at around $64/MWh on a 15-year loan, falling to $56/MWh with a 20-year loan, and $52/MWh for a 25-year loan. The database provides a valuable source of information on wind-turbine characteristics. There are more than 55,000 records. Just under 10% of these — 4,978 to be precise — were commissioned in 1998 or earlier, and so are at least 20 years old. More than 4,000 are at least 30 years of age, and the oldest were commissioned in 1981. California Energy Commission reports from the late 1980s and early 1990s provide data that enables the robustnes...
