I believe this information is very important – it’s the key to the solution of the renewables intermittency issue. https://cleantechnica.com/2022/07/10/converting-mines-into-hydro-powered-batteries/ “”A PUSH facility can be developed using mature technological systems—materials and machinery—used by conventional PSH. In what they call a conservative estimate, researchers determined the US has capacity for between 137 and 285 gigawatts of

An MIT Technology Energy Initiative study finds that storage can deliver carbon-free US grid. https://www.theenergymix.com/2022/06/14/storage-can-deliver-carbon-free-u-s-grid-mit-study-finds
Coal power plants that are closing early https://cleantechnica.com/2022/06/15/coal-burning-power-plants-closing-early/
I really like this all-in-one solar plus storage system which has both batteries and green hydrogen generation, storage and fuel cells. It’s expensive but everything is integrated into one package. https://electrek.co/2022/06/16/check-out-this-solar-green-hydrogen-mobile-nanogrid-with-a-level-2-ev-charger/
Gas turbine runs on 100% pure hydrogen. The skeptics are constantly complaining about how the wind and solar renewables “will never” be able to give the grid dispatchable power. Well, as long as gas turbines can run on hydrogen, they can still be used as generation as long as they burn green hydrogen. However there

Originally an EarthDay.org article. They made 3 points. They said, <<California must still rely on fossil fuels to meet its energy demands.>> The peak energy demands can be reduced by using a ‘smart grid’ where the grid has some control over the heavier demands. One example is residential HVAC and hot water. These can be

Burning fossil fuels accounts for 87% of global CO2 emissions. The cost of solar has fallen more quickly than experts predicted. https://cleantechnica.com/2022/06/08/just-the-facts-the-cost-of-solar-has-fallen-more-quickly-than-experts-predicted/
Zero carbon grid with VPPs – virtual power plants https://pv-magazine-usa.com/2022/05/31/achieving-a-zero-carbon-grid-opportunities-in-virtual-power-plants/
The house oversight committee examins Big Oil’s climate pledges. They need to hold the fossil fuel industry’s feet to the fire and make them pay penalties for failing to meet climate pledge promises and commitments. https://oversight.house.gov/legislation/hearings/fueling-the-climate-crisis-examining-big-oils-climate-pledges
Comparison of wind turbine waste. There really is no comparison – coal power plants generate hundreds of times more fly ash waste than wind turbines, and fly ash is toxic! Compared to coal, wind turbine waste is insignificant! Wind turbine blade waste generates 0.163 kg per MWh over a 20 year period. A coal power
