At a per capita rate, Australia is deploying renewable energy 8 times faster than the world average and nearly three times faster than the next fastest country, Germany. 99 This is positioning us at the leading edge of the development of enabling technologies for decentralised, low emissions energy systems. With our market and geographical characteristics, we are also emerging as leaders in niche technologies like hot climate batteries, off-grid systems, and rapidly deployable modular renewable systems.
