    In the rare case any here might want to look at modern technological solutions;
    ...
    Flue-gas desulfurization (FGD) is a set of technologies used to remove sulfur dioxide (SO
    2
    ) from exhaust flue gases of fossil-fuel power plants, and from the emissions of other sulfur oxide emitting processes such as waste incineration.

      The catch is developing economies. They make up the bulk of the global population, need lots of energy and material resources to industrialize, and is the main source of consumer markets.

          And the money favors coal being used for energy production all over the world. China, for example, cannot afford to convert to much of anything else, because they have a lot of coal, but very little oil, and if they run out, they will buy it from whomever has it, including us. That's how international trade works.

            My state is currently experiencing very high temps and last night one of the brown coal power plants suffered a setback, one generator went offline. So we've been told to conserve power use to avoid outages. Last January the same power station had 6 incidents in just a few weeks. The extreme heatwaves are pushing the coal power stations into the unreliable territory now.

              Prices are expected to gradually fall over the next two years in Australia, while the private sector won't be touching new coal power generation with a barge pole.

                One use to be considered for renewable energy is reverse osmosis water purification. The systems are, output flexible-= when energy supply is high, you can process and store purified water. The Reclaimed water becomes a de4 facto battery.

                A small amount of baseload is, apparently, called for to prevent the systems form inadvertently back washing.

                  Maybe should let Tom Steyer know that. After using USA coal to build his fortune he then moved on to Australian coal, and also decided to get involved in the "climate change" political actions here in USA
                  ...
                  In January 1986, Steyer founded Farallon Capital, a hedge fund firm headquartered in San Francisco, California.[13][14] Steyer made his fortune running Farallon, which was managing $20 billion by the time he left the company.[15] Steyer was known for taking high risks on distressed assets within volatile markets.[8]

                  In October 2012, Steyer stepped down from his position at Farallon in order to focus on advocating for alternative energy.[16][17] Steyer decided to dispose of his carbon-polluting investments in 2012, although critics say he did not dispose of them quickly enough and noted that the lifespan of the facilities he funded would extend through 2030.[18] A 2014 New York Times article said coal-mining companies that Farallon invested in or lent money to under Steyer had increased their coal production by 70 million tons annually since receiving money from Farallon, and that Steyer remained invested in the Maules Creek coal mine.[18] Prior to Steyer leaving Farallon, a student activist group called UnFarallon criticized the company for investments in companies with anti-environmental policies.[8] In 2016, some critics noted that Farallon had also invested in private prisons while Steyer was leading the hedge fund.[19] According to SEC filings, Steyer was at the helm as the hedge fund purchased nearly $90 million of Corrections Corporation of America stock (5.5% of the company's outstanding shares).[20] After leaving Farallon, Steyer hosted a two-day think-tank entitled the 'Big Think Climate Meeting' to discuss how to address climate change.[21]

                    I'm not convinced the price will fall, we've been promised similar claims back when it was privatised. The problem is, the high price has driven people to install solar panels etc. The other issue is that the brown coal plants are proving problematic in the extreme hot days and one of the major transmission lines tripped.
                    Nuclear power is being ignored when it shouldn't.

                      Truth is, the Libbies don't like any reliable source of power, until it comes to their own personal comforts. What they want is to live in fantasy world where everything works by magic.

                        Our power grid is likely o trip no matter what the power source is. It is extremely vulnerable.

                          You actually have a point there.
                          Coal fired electricity is 'tamper resistant'- plants can be more secure against intrusion. Hydro power dams can be vulnerable to a terror or nuisance attack.
