How will the reduced Renewable Energy Target affect investment?

After months of deadlock, a deal has finally been reached to reduce the Renewable Energy Target, ending the uncertainty for industry but also risking an already sparse pipeline of future projects.

Pumped hydro energy storage – making better use of wind

In late September, the Australian Energy Market Operator (AEMO) released a report investigating how wind can better be integrated into the power grid. AEMO reports that as more wind turbines are deployed…
Hydropower stations such as the Three Gorges in China are able to produce large amounts of electricity but they can also alter ecosystems and displace communities. EPA

Explainer: what is hydroelectricity?

Hydroelectricity is an established power-generation technology with over 100 years of commercial operation. Hydroelectricity is produced when moving water rotates a turbine shaft; this movement is converted…
