Rings of Neptune narrow, dusty ringlets and even fainter broad dusty rings. The rings of Neptune, like those of Uranus, are thought to be relatively young; their age is probably significantly less than that of the Solar System. Also, like those of Uranus, Neptune's rings probably resulted from the collisional fragmentation of onetime inner moons. Such events create moonlet belts, which act as the sources of dust for the rings. In this respect the rings of Neptune are similar to faint dusty bands observed by "Voyager 2" between the main rings of Uranus. The innermost ring of Neptune is called the "Galle ring"
Solar power in Australia the state government announced a new round of finance for renewable energy projects which included a Planet Arc Power - Schneider Electric development of a $13.9m solar PV and battery project at a major distribution centre in Adelaide’s North. The project includes a micro-grid management system optimising 5.7MW of solar PV coupled with 2.9MWh of battery storage. The University of South Australia will develop 1.8MW of ground and roof mounted solar PV at its Mawson Lakes campus. At the Heathgate Resources Beverley mine there are plans for a relocatable 1MW of solar PV paired with a 1MW/0.5MWh battery which will
