No, those neat round blobs look like maybe a kid’s squirt gun - amateur paintball game in the street?
Yes, and those responsible for distribution have been taking the money and sitting on their hands for quite some time now. They refused to consider that this situation would arise (where alternatives where generating above requirments) hence the problem now. As far as feed in payments, there should be single pay-in to the grid figure - x cents whether it comes from coal, solar, whatever; although this would need to be introduced slowly over time (should have started 20 years ago min) to avoid all the uneconomic providers going belly up. SA knew they were getting 150mW (in 100 days!) and did nothing to prepare for it.
Blame the regulators, not the distributors. Every aspect of their business is controlled by a dogs breakfast of often contradictory regulation. The rot started with Robert Hill in the Howard govt. Another South Australian green idiot, of which the Libs are increasingly infested. As for feed-in tariffs, they should be scrapped. Like most govt "incentives" the outcomes were not thoroughly considered. Anyone is welcome to install PV's to offset their own usage, but the nonsense of feeding power back (which is also a lie but too complex to explain here) is the root cause of what will become increasingly unreliable networks.

I’m not talking about feed in tariffs as ‘incentives’ but as SUPPLIERS - this is the crucial bit the distributors have missed - ther are alternative SUPPLIERS now; and some of the old suppliers are disappearing as they’re no longer viable. The whole systme needs a rebalance.

And for the record, not so beautiful when obsolete Welcome To the wind Turbine Graveyard Note the size of the bulldozer burying the blades in comparison to the blades. "Welcome to the wind turbine graveyard. It stretches a hundred meters {328 feet} from a bend in the North Platte River in Casper, Wyoming. California, Colorado, Kansas, and many other states are doing the same thing, the fiberglass blades will never deteriorate {not biodegradable}. Between last September and this March, it will become the final resting place for 1,000 fiberglass turbine blades. These blades, which have reached the end of their 25-year working lives, come from three wind farms in the north-western US state. Each will be cut into three, then the pieces will be stacked and buried. Turbines from the first great 1990s wave of wind power are reaching the end of their life expectancy today. About two GigaWatts worth of turbines will be refitted in 2019 and 2020. And disposing of them in an environmentally-friendly way is a growing problem. This cost taxpayers $200,000 or more per unit, or 200 million total for the 1000 blades, to have them transported and decommissioned. Image Unavailable, Please Login Image Unavailable, Please Login
There was a similar article about the blade disposal problem in the UK, but it's been disappeared off the internet and replaced with feel-good stories about 5 blades being used for children's playgrounds. Ocean based windmills have approximately half the life of land based units. btw California doesn't permit the burial of old blades, so they export their pollution to other states.
Pyrolysis is the process of chemically decomposing or transforming a material into one or more recoverable substances by heating it to very high temperatures in an oxygen-depleted environment. This is different from incineration, which takes place in an open atmosphere….Pyrolyzed fiberglass decomposes into three recoverable substances: pyro-gas, pyro-oil, and solid byproduct— all of which can be recycled. Scrap automobile tires are disposed of by pyrolysis (the tire mountain in the United States is over 3 billion tires, growing at the rate of 250 million tires a year). To pyrolyze SMC, it is shredded into 2” squares that are fed directly into the pyrolysis reactor by a vacuum assist, which also draws off most of the oxygen in the atmosphere. The reactor is then heated to around 14000F (7760C). At about 5000F (2760C), the hydrocarbons in the resin decompose into gas. The gas is drawn off and sent through a scrubber, which separates it into pyro-gas and pyro-oil. The pyrogas is very clean and has an energy content similar to natural gas. It can be sold as a natural gas replacement, and it fuels the burners of the pyrolysis reactor so that the reaction is self-sustaining. Pyro-oil is similar to heavy crude oil and, as such, it has less value than normal crude oil, but it can be blended with other fuel oils or incorporated into asphalt. Pyro-gas and pyro-oil comprise about 25% of the pyrolysis traction output in roughly equal amounts. These are free of sulphur, halogens, phosphorous, heavy metals, or other elements that can cause environmental problems.problems. amounts.

Unfortunately, modern turbine blades are not just fiberglass and can't be recycled. They have different composites in different areas, e.g. the leading edges and the tips.
