Wind energy is a renewable energy source that is being harnessed globally to reduce our dependence on fossil fuels and the associated impact on our environment. However, the environmental impact of the turbine noise and the blade pass noise is a concern that is carefully monitored and generally regulated. It is very important to be able to acquire accurate acoustical data for analysis, noise impact predictions, and regulatory compliance. Effective noise monitoring is a very valuable tool to manage a wind farm’s relationship with the community and with the local regulatory organizations.

Carbon fibre is a unique material and is found in many high-tech industries such as sports car manufacture, wind turbine blade construction and sports equipment. The production of carbon fibre from acrylic fibre involves the baking of the fibre in ovens, which gives emissions of gas species including Hydrogen Cyanide (HCN). Protea’s range of gas analysers can provide a solution for the periodic or continuous measurement of gases from carbon fibre production in order to give reportable emissions values as required by legislation.
