New wave of wind energy

An offshore wind test turbine has been erected behind the University of Maine Advanced Structures and Composites Center on campus to evaluate sensor systems and controls in preparation for the installation of a floating turbine ...

Solar and wind energy may stabilise the power grid

(Phys.org)—Renewable energies such as wind, sun and biogas are set to become increasingly important in generating electricity. If increasing numbers of wind turbines and photovoltaic systems feed electrical energy into ...

A digital "stethoscope" for monitoring equipment

An intelligent diagnostic system from Siemens can monitor the condition of mechanical equipment just by analyzing the noises it makes. The system's sensors listen to machine noises in the same way that a doctor listens to ...

Grid realities cancel out some of wind power's carbon savings

(Phys.org) -- Wind energy lowers carbon emissions, but adding turbines to the current grid system does not eliminate emissions proportionally, according to a report by researchers at the Argonne National Laboratory.

Wind turbines that learn like humans

Depending on the weather, wind turbines can face whispering breezes or gale-force gusts. Such variable conditions make extracting the maximum power from the turbines a tricky control problem, but a collaboration of Chinese ...

Smart paint could revolutionize structural safety

An innovative low-cost smart paint that can detect microscopic faults in wind turbines, mines and bridges before structural damage occurs is being developed by researchers at the University of Strathclyde in Glasgow, Scotland.
