Wind Energy Technology
     Developing new processes to generate power (converting mechanical or thermal energy into electricity) has eventuated in more sophisticated solar (photovoltaic) cells and emission capture technologies.

Using 'non-destructive' energy conversion processes has long term social economic benefits and involves personal recognition of waste management from electricity production and use.
     During the historical development from slow moving 'windmills' to modern wind turbines, more rigorous knowledge about aerodynamics was under development and allowed the late designs to incorporate airfoil sections, providing 'lift' force on the blade.

Wind turbine technology has an identified limit for the efficiency in which kinetic energy can be converted into electricity, described mathematically as the 'Betz Limit' of ~59%.

The practical application for wind power generation was not obvious until the impact of fission and fossil fuel based technologies had become relevant.
Waste production is an ongoing issue for older and less effective technology that has approached the limit of efficiency in its design.
