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.

2020-10-03 Tesla And Hydrogen
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

2020-10-01 Renewables Don’t Need Baseload Power
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
2020-09-10 Model Of Least Cost All Renewables Grid
This is supposed to be a least cost model. Solar reaching up to 4.3 times capacity. I would expect that much of the curtailment would be replaced by “flexible loads” controlled by the grid, most of which would be hydrogen generation. The hydrogen could be stored and used for longer term storage/generation and/or transportation fuel.

2020-09-03 Distributed Generation And Islanding
There is a lot of concern for safety when DGs (distributed generators) are connected to the power grid. The grid operators must ensure that none of the DGs feed back into the grid when the grid generator is not operating. They go through several scenarios in this article. https://electrical-engineering-portal.com/protection-impacts-intentional-islanding-distributed-generation From what I see the DG

2020-08-31 Costs of Wind Power; Life Cycle GHGs (Wiki)
From https://en.m.wikipedia.org/wiki/Cost_of_electricity_by_source The cost of wind power is less than solar. << In the windy great plains expanse of the central United States new-construction wind power costs in 2017 are compellingly below costs of continued use of existing coal burning plants. Wind power can be contracted via a power purchase agreement at two cents per
