Wind Turbine Prices

A more or less continuous slide over the last 30 years.  My calcs give me a 5% per annum compound decline in cost, not the 14% shown on the chart, although that is not against time  but against (I assume) installed capacity (hence the note below the chart of 'learning rate').

This is not as fast as the fall in PV cell costs (+-18% per annum) but still means that costs have fallen 75% in 28 years.
