At 13:00 Dave talked about how problematic green hydrogen is, and at 13:30 he said why not just use the electricity directly for the home. Herein is the whole problem: the solar and wind electricity is generated at times when it is not needed and not generated when it is needed. So we still have

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,

This long article is about carbon capture and sequestration with a section on DAC direct air capture. We must reduce the 410 parts per million in our atmosphere! Quote: << Lackner says DAC is a good fit with renewable energy. If a natural gas power plant is off because of low demand, so is any

The cost of green hydrogen must come down or else the gas turbines must be used as a peaker plant during the time when high demand causes electricity price to spike. As the percentage of renewables increases, this may happen more often. But that will cost consumers. https://www.pv-magazine.com/2021/07/14/hydrogen-fired-gas-turbines-vs-lithium-ion-storage/
There are so many authors that point out that fossil fuels have killed many, many more people than nuclear power plants. They have a standard claim that “only a hundred people have died, directly because of nuclear power”. But then they claim that millions have died because of fossil fuels, however those deaths are indirect,

Report from BloombergNEF says new solar is cheaper to build than to run existing coal plants in many cou,ntries. Tony Seba’s (RethinkX) prediction was correct. https://www.renewableenergyworld.com/solar/report-its-now-cheaper-to-build-new-solar-than-to-run-existing-coal-plants-in-china-india-and-most-of-europe/
This is a horror story. This Frontline episode first aired 2017 Oct 11. << Make the regulated the regulators >> AKA Foxes in charge of the chicken coop. Thank God we got rid of Trump and Scott Pruitt and the EPA can now get back to doing what it’s supposed to be doing. https://youtu.be/vFfYKOTj-48
There are those who complain about the amount of water used to mine the battery raw materials such as lithium. But the water used to mine a kg of lithium is only used once. They also complain about the water or other materials used to make wind turbines. That water is used only once. But
