Australia, with 12.3% of its electricity generated by solar, is third highest worldwide, behind Chile (18%) and Honduras (12.5%) according to Energy Monitor. But we have the potential to gain further ground with many developments underway. These include a Queensland Gov plan to reach 70% renewable electricity by 2032 (see ABC announcement) and NSW establishing 5 Renewable Energy Zones (see Gov data below).
Combined with the earlier-than-expected closure of Loy Yang coal-fired Power Station in Victoria (currently providing 30% of electricity) - we are truly in a transition, but we still need a speed-up.
