General technology trends:• Fuel efficient cars
• Alternate fuels (CNG, LPG, E-10)
• Hybrid propulsion
• Plug in electrical vehicles
Carbon fibers for wind energy and automotive
General technology trends:• On shore to off shore
• Increase of rotor-blade size
• Rotor-blades with higher strength to weight ratios
• Integrated systems such as wind-diesel, wind-SPV, wind-battery etc.
