The greenies' dream of "clean" energy from wind farms is dying in the face of the poor economics (even with tax subsidies) and unreliable technology
- The big players in constructing wind turbines are facing massive losses and write-downs and cancelling big offshore wind projects
- Green energy subsidiary of German electrical equipment giant Siemens lost nearly a billion dollars in the last quarter
- One fundamental problem with wind energy is the variability of the wind.
- In order to get a meaningful amount of power, the blades have to be BIG, which is why the towers of major wind farms are very tall
- Long blades spinning rapidly can have the tips break the sound barrier, and the stresses on the materials used in the blades are intense
- As a result, order books of the major manufacturers are drying up
