It’s in the stars! How scientists figure out your home’s energy rating
For nearly 70 years, CSIRO scientists have been working on the science behind the 10-star energy ratings for homes in Australia. We look at how CSIRO’s tools are used in the Nationwide House Energy Rating Scheme, and the science behind the stars.

Diverse array of energy-storage technologies may be key to firming the grid
Australia has been described as a powerhouse of cheap renewable energy. However, when the sun doesn’t shine or the wind calms, the power-switch flicks off – a problem referred to as intermittency.
