General technology trends:
General technology trends:
• On shore to off shore
• Fuel efficient cars
• Increase of rotor-blade size
• Alternate fuels (CNG, LPG, E-10)
• Rotor-blades with higher strength to weight
ratios
• Hybrid propulsion
• Integrated systems such as wind-diesel, windSPV, wind-battery etc.
