The modern wind
energy technologies and recent global wind energy market trends are reviewed in
the paper. Basic principles of conversion of wind energy to electricity are
described with brief overview of the state-of-the-art technologies for
subassemblies such as wind turbine blades and drivetrains. Global wind energy
market was reviewed in order to attain notion of wind power market developments
in the future. The most developed countries in terms of wind energy utilization
such as Denmark, Germany, Spain and USA were identifi ed as the key drivers of
wind energy technology advances. After the long leadership of European Union in
built annual wind power capacities, China and USA have overtook leading
positions for the last several years. Wind energy costs per unit of electricity
produced after gradual decrease until 2005 have recorded slight increase until
the present due to high demand and higher raw materials price. It was predicted
that the trend of the wind energy cost will decrease in the future. Steady
growth of wind energy capacities was predicted in the next years, with forecast
that present global installed capacities of nearly 200 GW should grow to almost
one terawatt by the 2020.

Approaches for High Performance Composite Rotor Blades”, that has been funded
by Ministry of Education and Science of Republic Serbia.
