Near 100 pct renewable electricity for Australia’s main grid is achievable and affordable: Year 4 update
Very close to 100% renewable electricity is feasible for Australia’s main grid at reasonable cost using just several hours of storage. Four years of data proves this is so.

More than just “fuel saving:” How rooftop PV slashed grid demand in middle of heatwave
In last week’s heatwave, wind and solar generation were excellent, as they typically are on extreme demand days – certainly doing more than just ‘fuel saving’.

A rule change on transmission losses for wind and solar farms could save billions for consumers
A ruling that effectively charges wind and solar farms for twice actual transmission losses represents a large risk to developers of new generation assets, and consumers.

How to run the National Electricity Market on 96 per cent renewables
Windlab simulation of 96% renewable NEM shows very high renewables penetration is possible with boosted wind and solar, firmed by existing hydro and readily achievable levels of storage.

Deep dive into the ACT’s 100% renewable energy target
Contracted wind and solar generated 98% of ACT’s net demand over past year, and 78% of ACT’s electricity could theoretically have been supplied directly from wind and solar without storage.
