Rooftop solar makes South Australia the world’s first gigawatt-scale system to hit negative demand. One thing that angers me is that they said they may have to shut off some rooftop solar to cut back the supply. That “curtailment” should be made illegal. The law should require that all excess renewables generation be used to

Thread from FB << Michael Burns Concentrated Solar Power (CSP) is a totally different technology, which has a lot of operational advantages over PV, but still many disadvantages compared to other generation types. Functionally, CSP is simply thermal energy storage, so like a battery, when it’s “charged”, it can be included in the short term

Utilities should capture CO2 directly from power plants, while it’s still highly concentrated. The following is from: https://19january2017snapshot.epa.gov/climatechange/carbon-dioxide-capture-and-sequestration-overview_.html << As estimated in the U.S. Inventory of Greenhouse Gas Emissions and Sinks, more than 40% of CO2 emissions in the United States are from electric power generation. >> << According to the Greenhouse Gas Reporting Program,

But it’s obvious that the electric utilities are promoting this because the utilities are afraid that rooftop solar will take away the utilities’ control of where the electricity comes from. The rooftop solar plus battery

For those who claim that nuclear power is safe. Here is a quote from Wikipedia biography on David E. Lilienthal: << In his 1963 book, Change, Hope and the Bomb, Lilienthal criticized nuclear developments, denouncing the nuclear industry’s failure to have addressed the dangers of nuclear waste. He suggested that a civil atomic energy program
