Wind Turbine – Overview of Issues and in Turbine Technology

DUBLIN–()-  Wind turbines have begun to be used for electrical generation, having previously been used for agricultural and grinding purposes. Initial wind turbines had a very small capacity, as well as very low efficiency and performance standards. Wind turbines have gone through various technological advancements during the time they have been in use. Each and every component of a wind turbine has been upgraded to make wind power generation more reliable and efficient.

Multi-Megawatt (MW) wind turbines are currently in use, which are easily delivering an availability factor of 95% or higher. A number of technological changes have been made to wind turbines, all of which have resulted in the improved performance of wind power generation.

Rotor blades have seen improvements in blade aerodynamic profiles as well as improvements in blade material properties, resulting in the production of large rotor blades that have made wind turbines capable of capturing more wind power. Wind turbines used to be fitted with gearboxes with a higher gear ratio, which had high maintenance requirements and low reliability. Continue reading

“Green Curtain” Initiative: KYOCERA Greens Company Buildings and Saves Energy

KYOTO, Japan–()–As part of its traditional environmental protection and sustainability activities, Kyocera Corporation (NYSE:KYO)(TOKYO:6971) plants Green Curtains every spring at its sites in Japan and select Kyocera Group companies in other parts of the world. Through the hot summer, curtains of foliage are grown on trellises in front of office windows and walls at company sites. This not only provides shade but also shields the buildings from heat radiation — decreasing inside room temperatures by approximately 3.6 degrees Fahrenheit*, which contributes to a reduction of energy consumption from air conditioner usage.
