The competitiveness of wind powered generators built in Croatia has been investigated. Wind characteristics at suitable sites at 35-m height have been calculated by applying Weibull wind-distribution functions with altitude corrections suggested by Justus. Two sites on the Adriatic coast have been identified as promising locations and analyzed in detail, using a generally applicable method. Wind-power utilization at one of the sites with the best wind-energy potential in Croatia is now marginally competitive with fossil-fuel systems.
