Collgar Wind Farm

High over the Western Australian Wheatbelt, 111 tall white wind turbines turn, each casting a shadow like a sundial across the fields.

It’s the Collgar Wind Farm, and it’s fully owned by Rest. We’ve invested your super in wind energy since 2011, which means Rest members have been doing their bit to keep the lights on in a more sustainable way.

What's a wind farm?

A wind farm is made up of lots of wind turbines grouped together. When the wind spins the blades, the turbines convert the wind’s kinetic energy into electricity, which feeds the grid and powers houses, businesses, and industry. 

Why wind power?

Australia, like many other countries, has committed to the Paris Agreement, a global treaty that aims to hold the increase in the global average temperature to well below 2°C above pre-industrial levels, and to pursue efforts to keep warming to less than 1.5°C. One way to contribute to these goals is to replace fossil fuels with clean, renewable energy sources. Wind is one of the main types of renewable energy, along with solar, hydro, geothermal, and biomass.

Rest’s investment in Collgar aligns with the Australian government’s emissions reduction target and with our target to achieve net zero carbon emissions in the fund by 2050. Investments like Collgar Wind Farm will help us get there.
