Meet 1KOMMA5° Australia

1KOMMA5° is Australia's Heartbeat of New Energy. Our vision is for Australians to live on sunlight and wind forever for free, by providing access to the cleanest and most affordable electricity possible.

Founded in Germany, our name says it all, and translates to 1.5 degrees (1=1, KOMMA = Decimal, 5=5, ° = Degrees). This speaks directly to the Paris Climate Agreement, preventing a further global temperature increase of 1.5°. 

1KOMMA5°'s CEO, Luke Stronach, explains how 1K5° Storage and Heartbeat AI, built on German engineering excellence, ensures you get the cheapest energy at the lowest cost.
