Along with major techniques as discussed above, there are some techniques which are attaining a commercial stage. One of the techniques is ‘Airborne Wind’ in which flying turbine devices which have 90% less mass than traditional wind turbines are used (IRENA 2016). At 300 m above altitudes, these turbines can generate power from the low‐speed winds. This technique covers a range of concepts such as rigid wings and airborne rotors. This technique can generate electricity at a lower cost due to less material usage, low capital expenditure and higher energy production compared with conventional turbines (IRENA 2016).

Apart from innovations in technologies, developments are also taking place in operation, maintenance and services (IRENA 2016). Due to higher growth rate in offshore wind turbines, there is a need of advances in the technology systems to keep track of turbines and to avoid failures. One such operation and maintenance tool is ‘Condition Monitoring Systems’ which help operators to forecast any problem with the working of wind turbines or failure of any components so that replacement can be done in advance to avoid any accident (Froese 2017).
