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.

This self-contained solar PV factory takes in sand and electricity in and puts out solar panels. But where do the other materials come from? Like the metal frame, the solder, the copper wire? https://www.inceptivemind.com/maana-electric-terrabox-turns-sand-electricity-solar-panels/20389/
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

New Wind, Solar just Keeping Up With Growth In Demand! We need more! https://electrek.co/2022/03/30/in-a-world-first-solar-and-wind-generated-10-of-power-for-50-countries-in-2021/ This article seems to paint a picture that’s too rosy. This “global think tank” doesn’t have as much credibility as the UN IPCC. https://www.pv-magazine.com/2022/04/08/solar-power-on-pace-to-save-the-world/
From FB group It’s not fair and unacceptable to blame wind turbine blades for being a landfill problem. Only 10 to 12% of the total plastic in landfills is due to wind turbine blades. Stop complaining about what’s in the landfills and complain about the plastic waste that’s turning the oceans into trash dumps and

There are those cynics who harshly criticize wind turbines for “filling up landfills”. That’s a false assertion. These badmouths never say anything about the *other* 87.5 to 90% of plastic waste that is filling up landfills. When compared to the rest of plastic waste, the amount that wind turbine blades generate is insignificant. The blades

Piotrek Puczek Said, “I am being critical because we need to do more to reduce wind turbine production and blade and life recycling.” It’s useless information about how many Teslas fit on a wind turbine blade. The blades last a long time when maintained, and they are developing automated inspection and maintenance equipment. Everyone is

Geoff Goeggel I have nothing against you, but you just need to be realistic. Right now, the world is already ‘on its way’ to saving $2T a year with renewables, but most of that is solar because most people don’t live where it’s very windy. You say 250 foot tall, but that says nothing about

https://www.pv-magazine.com/2022/03/29/solar-starts-strong-in-the-u-s-growing-40-year-over-year-in-january/ Comment on FB group (look at the bar graph) This article said “…Nearly 40% year-over-year.” That’s good but not good enough. That needs to be more than 100% year-over-year. The whole solar industry depends on the wafer fabrication facilities, which have grown but demand is still exceeding the supply. The US needs a large
