This guy goes over the changes when NEM 3.0 takes effect in 2022. The smaller bill with lower solar power will be at a disadvantage and there will be a disincentive to get rooftop solar. In other words the owner will save minimal or no money over the lifetime of the system. Also the solar

My comment from JHAT of this date with subject of space based solar power stations I pose the question: Should we (humans) collect solar power and beam it down to Earth by microwave or laser? The answer, and I quote, is “No. Don’t be ridiculous.” Are you serious? Who in their right mind would attempt

Engineering with Rosie dives into the VALCOE – value adjusted levelized cost of energy. This is adjusted for time of use – most solar is available only during daylight hours. https://youtu.be/6_BGHy4sfMs She uses a car race analogy to compare the solar, onshore wind, coal and gas. Solar and wind win the race. One thing I

California leads with more than 10 GW, many times that of second place. Texas and Florida are adding a lot more. The incentives are important! They don’t say, but I assume that this includes ‘behind the meter’ rooftop solar. https://www.eia.gov/todayinenergy/detail.php?id=46996
The Biden administration is approving 3 large solar PV farm projects on BLM lands in Riverside County, California. These utility scale projects total nearly 1 Gigawatt capacity. Up to 25 more will be built in other states. https://electrek.co/2021/12/23/biden-administration-approves-three-big-solar-farms-on-public-land/
These claims were put forth by 1.) Solar is unreliable and makes the power grid more susceptible to blackouts. A- FALSE – Weather predictions make solar power predictable and storage makes solar or wind predictable and dispatchable. Rooftop solar plus battery storage and an islanding inverter gives a home protection against blackouts. 2.) Electricity costs

Biden’s Build Back Better Act would boost solar installs 31% through 2026. https://electrek.co/2021/12/14/bidens-build-back-better-act-would-boost-solar-installs-31-through-2026/
A 24 min YouTube video: Generation of ammonia using solar energy: GCEP symposium Jens Nørskov Oct 8, https://youtu.be/FayZdrPx6xo Most fertilizer is made from ammonia. Humanity is heavily dependent on fertilizer for growing food. 1% of the world energy is used in the Haber-Bosch process to make ammonia. High energy: not as high as gasoline but

<< Using solar panels with an efficiency of 16% to supply the world, we would need to cover an area of 367 by 367 km or 135,000 sq. km. One USA based study concluded that the land required would be smaller than the current existing footprint of the existing system. >>
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
