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

2020-08-12 The Future is Green Hydrogen and Electricity From Renewable Sources

I’ve been paying a lot more attention to my blog and especially with adding the links to the articles and books I’ve been reading. I have made investments in companies that see the future is away from fossil fuels and towards all renewables. And the companies that are going to produce green hydrogen to use

2020-07-28 Solar Power & Afghan Opium Production; Renewables vs. Other

Solar Power Has Transformed Afghan Opium Production This crazy story isn’t one that’s for the better. But Solar power has transformed the poppy growers in Helmand Province in Afghanistan. Crazy world. https://www.bbc.com/news/science-environment-53450688 Renewables Outpaced Coal and Nuclear to start 2020. https://pv-magazine-usa.com/2020/07/27/renewables-have-outpaced-nuclear-and-coal-to-start-2020/

Oilprice.com article https://oilprice.com/Alternative-Energy/Wind-Power/Wind-Is-Emerging-As-A-Leader-In-The-Renewable-Race.amp.html Quote << “We have reached an important turning point in the energy transition. The case for new and much of the existing coal power generation, is both environmentally and economically unjustifiable,” said the director-general of IRENA, Francesco La Camera, commenting on the agency’s latest report. “Renewable energy is increasingly the cheapest source

2020-07-11 DIY Off Grid Solar System

This is a YouTube video. This guy did a very good job of building an off-grid solar system. It’s transportable, uses four 100 watt panels, two 12V AGM batteries in parallel, can supply 120VAC pure sine wave at 2000 watts and costs under $1,900. This is an excellent video with plenty of details. He calls
