A wind energy generation turbine is built to take advantage of high winds in mountain passes and other areas of extreme wind velocity. A windmill section is raised high by support structures. Electricity generators are kept in the base of the windmill to reduce elevated weight. A nozzle or shroud channels wind into a narrow raceway to take advantage of the Venturi effect. Windmill blade tips housed within a circular raceway are strengthened by blade tip connectors and blade spar struts against high wind forces. Windmill blade angle and windmill wind facing are dynamically altered by computerized motors for maximum efficiency. Windmill blade angle and/or generator load maintain ratio of windmill blade tip speed to wind speed for efficiency. Turbine speed translation gears are able to decouple windmill from 60 Hz cycle or use water pumps and gravity to store energy at peak generation times.
