Wind power became a significant energy source within South Australia over the first two decades of the 21st century. In 2015, there was an installed capacity of 1,475 MW, which accounted for 34% of electricity production in the state. This accounted for 35% of Australia's installed wind power capacity. In 2021, there was an installed capacity of 2052.95 MW, which accounted for 42.1% of the electricity production in the state in 2020.

The development of wind power capacity in South Australia has been encouraged by a number of factors. These include the Australian Government's Renewable Energy Target, which require electricity retailers to source a proportion of energy from renewable sources, incentives from the South Australian Government including a supportive regulatory regime and a payroll tax rebate scheme for large scale renewable energy developments. Also the state's proximity to the Roaring forties means there are high quality wind resources for wind farms to exploit. In mid-2009, RenewablesSA was established by the South Australian Government to encourage further investment in renewable energy in the state.

The load factor (or capacity factor) for South Australian wind farms is usually in the range of 32-38%. This means that a wind farm could typically produce between 32 and 38% of its nameplate capacity averaged over a year. (Full article...)

• "The sunlight ... that strikes Earth’s land surface in two hours is equivalent to total human energy use in a year. While much of that sunlight becomes heat, solar energy is also responsible for the energy embodied in wind, hydro, wave, and biomass, each with the potential to be harnessed for human use. Only a small portion of that enormous daily, renewable flux of energy will ever be needed by humanity."

• "Improved energy productivity and renewable energy are both available in abundance—and new policies and technologies are rapidly making them more economically competitive with fossil fuels. In combination, these energy options represent the most robust alternative to the current energy system, capable of providing the diverse array of energy services that a modern economy requires. Given the urgency of the climate problem, that is indeed convenient."

Elon Reeve Musk (/ˈiːlɒn/; born June 28, 1971) is a businessman and investor known for his key roles in space company SpaceX and automotive company Tesla, Inc. Other involvements include ownership of X Corp., formerly Twitter, and his role in the founding of The Boring Company, xAI, Neuralink and OpenAI. He is one of the wealthiest people in the world; , Forbes estimates his net worth to be US$214 billion.

Musk was born in Pretoria to Maye and Errol Musk and briefly attended the University of Pretoria before immigrating to Canada at age 18, acquiring citizenship through his Canadian-born mother. Two years later, he matriculated at Queen's University at Kingston in Canada. Musk later transferred to the University of Pennsylvania and received bachelor's degrees in economics and physics. He moved to California in 1995 to attend Stanford University, but dropped out after two days and, with his brother Kimbal, co-founded online city guide software company Zip2. The startup was acquired by Compaq for $307 million in 1999. That same year, Musk co-founded X.com, a direct bank. X.com merged with Confinity in 2000 to form PayPal. In October 2002, eBay acquired PayPal for $1.5 billion. Using $100 million of the money he made from the sale of PayPal, Musk founded SpaceX, a spaceflight services company, in 2002.

... that Selling Solar: The Diffusion of Renewable Energy in Emerging Markets, a 2009 Earthscan book by Damian Miller, argues that in order to solve the climate crisis, the world must immediately and dramatically accelerate the commercialization of renewable energy technology ? This needs to happen in the industrialized world, as well as in the emerging markets of the developing world where most future GHG emissions will occur.
