San Diego Gas & Electric talk about electrification, which I assume means changing from natural gas to electricity. They base their predictions on needing more renewables plus storage and green hydrogen. They haven’t taken into account that by 2045, sea level rise may force hundreds of thousands of people to have to relocate further inland.

Dave @ JHAT discusses photovoltaic thermal panels and a system by Sunova. The panels are kept cooler and can last much longer – fifty years. My patron comment: The solar water heater panels have been in use for many decades, since before 1980. I’ve often thought that solar PV should be sandwiched with these solar

Cohoes, NY will use reservoir for 4 MW solar array. Quote: << “…researchers estimate that installing floating solar photovoltaics on the more than 24,000 man-made U.S. reservoirs could generate about 10 percent of the nation’s annual electricity production.” >> https://cleantechnica.com/2022/03/20/tiny-cohoes-to-floating-solar-wallflowers-catch-me-if-you-can/
This article outlines the incredibly huge amount of solar panels that China is supplying to be installed, much of them in China. The figures are astounding! Quote: << Thus far, 24 of China’s 31 provinces and regions have set out five-year-plan renewables targets which include plans for 375-420GW of solar by 2025 – around 75-84GW

This article shows the synergy between solar PV and the use of the canals as the location for solar canopies. They call it agrivoltaics but there is no agriculture or crops. The author said there are three benefits. But the author did not include the added benefit that the canal water keeps the solar panels

This is in Indiana in Indiana courts. But it may set precedent for future rulings in other state or federal courts. Consumers with rooftop solar are getting fed up with the utilities changing or removing the pay that they’re getting for selling solar power back to the utility. The court needs to make a rule

This guy runs everything off hydrogen. He makes his own, stores his own and powers everything from green hydrogen. He has six patents dealing with hydrogen. He made his own system. https://youtu.be/NMH1pBAYgYs GKN Hydrogen’s HY2MINI demonstrator. This is a similar setup. The solar array powers the electrolyzer. The green hydrogen is stored in metal hydride

This ad popped up and I had to watch this little workhorse do its jobs. It gave me several thoughts of what it could be used for. It even can work in the dark and in the rain. It said that it’s 64 HP and $14,800.00. When I was a kid, I remember seeing articles

Polysilicon shortage Quote: << The latest global PV industry outlook published by trade group SolarPower Europe, has indicated tight supply of the solar panel raw material is expected to persist this year but the trade body said it would be unlikely to drive further price rises. >> https://www.pv-magazine.com/2021/07/22/polysilicon-shortage-will-continue-through-2021/
Article about the ‘dark side of solar.’ More recycling of solar and wind needs to be done to prevent the panels from ending up in landfills. (Harvard Business Review) https://hbr.org/2021/06/the-dark-side-of-solar-power
