STELR Career Profiles in STEM – Wind Energy Engineer

These videos explore the work of Senior Mechanical Wind Energy Engineer, Rosemary Barnes and provide a step-by-step tutorial for students to design their own turbine blades using CAD.

Wind energy is one of Australia’s main sources of renewable energy with over 100 wind farms in Australia at the start of 2020. Wind energy is one of the lowest-cost sources of electricity generation in Australia and, in 2019, it generated 8.5% of all of Australia’s electricity.

Wind turbines use the kinetic energy of the wind to spin an electric generator to produce electricity (electrical energy). The blades come in different shapes and sizes and are mounted at different angles; this changes the efficiency of the turbines.
