A quote from https://www.eia.gov/outlooks/steo/ << EIA forecasts that planned additions to U.S. wind and solar generating capacity in 2021 and 2022 will contribute to increasing electricity generation from those sources. EIA estimates that the U.S. electric power sector added 17.5 gigawatts (GW) of new wind capacity in 2020. EIA expects 15.3 GW of wind capacity

Every second, by thermonuclear fusion, the Sun converts 564 million tons of hydrogen to 560 million tons of helium. Where did 4 million tons go? The 4 million tons that are missing are converted into energy – photons, including sunlight. This energy amounts to 380 billion Megawatts, or 380 million Gigawatts, or 380,000 Terawatts, or

The Hornsdale Battery Storage has made a big disruption in the market for electricity in South Australia. Since it can supply electricity almost instantaneously it outcompetes the gas turbine generating plants even though it is a much smaller percent of the total electric supply. The South Australia state has a large amount of renewables –

This train runs using an EV battery! Amazing. We need a lot more like it. Tom Scott’s short video https://youtu.be/6Y4QGFte3T8 More information on this and other solar trains https://futurism.com/worlds-first-fully-solar-powered-train-left-station
Spain will close most of the coal fired power plants within a year. Plans to stop fossil fuel subsidies and ban new extraction. https://amp.theguardian.com/environment/2020/nov/11/climate-heroes-the-countries-pioneering-a-green-future This is what all countries including the US should be doing.
I’ve seen so many locations in Southern California that are pretty much barren mostly because the country is lacking water. The cost of water in So. Cal. is high because there are so many people that the water they need has to be imported from hundreds of miles away — as far as Northern California.

This self-contained system uses solar PV panels as the only power input. It generates and stores green hydrogen, then uses it later for both electricity and heat. The fuel cell’s byproduct is water. One important “problem” that I see is that this system makes the customer completely independent of the electricity _and_ gas utilities. There

My comment to a YouTube video. Like Tom says, “in my opinion…” There will be an upward trend in the production of green hydrogen and consequently a downward trend in the cost per kg. Large fleets of heavy vehicles can be converted from diesel to hydrogen, and it has the advantage of faster refueling than

This 4.7 min. TED Talk Youtube video dispels the myth that solar and wind can’t do the job without “base load” power. Amory Lovins is with the US NREL, and is an authority on this subject. He also states that renewables are less expensive than fossil or nuclear power. https://youtu.be/Oo8iEL6SqgI
Matt Ferrell has the text to his YouTube video about the Tesla Powerwall, Sonnen, etc. and a link to the video. The Tesla Powerwall and others cost about $10,000 installed. The systems may allow you to run your home from the battery when there is a power outage on the grid. Solar PV panels will
