Everyone complains that China is the worst polluter and CO2 source. But things will change. From comment in FB group renewable energy China has a lot more solar than any other country, and produces a lot more renewable energy. If the conventional thermal power plants, which require constant refueling, can’t compete with the solar and

There is a lot of power being wasted by pressure reducers in water mains. In this YouTube video Matt Ferrell looks at microhydro- and picohydropower turbine-generators that are powered by the drops caused by pressure reducers in water systems. These are capable of generating hundreds to tens of thousands of watts and recover energy that

I’m hopeful that more of these green hydrogen electrolyzer systems are going to be installed. The hydrogen is accomplishing more than one thing. The electrolyzers are putting to good use the excess renewables power that would otherwise be wasted. The green hydrogen is, of course, being used to replace fossil fuels, and thus reducing CO2

This article (or video) has some good graphs for future distributed PV plus batteries.https://www.volts.wtf/p/rooftop-solar-and-home-batteries A map of generation sources in the US. https://mobile.twitter.com/VibrantCE/status/1338560961280618502/photo/1
This YouTube video by Tony Seba is stating that utility scale batteries of 2% disrupt 90% of fossil fuel peaker plants. This video has a lot of graphs showing the trends. https://youtu.be/AV3MweskE0w The amount of utility scale batteries needed to replace much of the peaker plants is just a small percentage. 200 mile range EVs

This YouTube video from Tony Seba of RethinkX shows the incredible cost reductions that have been and will be made to the cost of solar, wind plus battery storage. “SWB100” is his acronym for 100% solar, wind plus battery storage. Seba states that SWB100 will be so low, per kWh, that it costs less than

From FB group reply Andrew Roddy You failed to state the obvious. Hydrogen, despite its inefficiencies, is more efficient in FCEVs than fossil fuel in ICEVs. And its distinct advantage for heavy transportation is the refueling time can be the same as fossil fuels. See charts below. One more pro for hydrogen efficiency, see this

From YouTube comment The third most important thing (after air and water) is food, and agriculture uses huge amounts of hydrogen in making fertilizer. Now, the hydrogen is made using fossil fuels, mostly methane, and the fossil fuels must be eliminated ASAP. The hydrogen must be made by other than fossil fuels and the governments

This Youtube video Engineering With Rosie interviews a chemical engineer who talks about the problems of replacing some or all of the natural gas with hydrogen. Hydrogen has higher energy per unit weight, but it is much less dense than methane so it has much less energy per unit volume. The natural gas system has

From FB group TSLA Shareholders De Bits Said, “…analysts … are focused on million mile battery which is moot if not irrelevant.” To you, Mr. De Bits, it may be irrelevant because you are apparently clueless about how important the lives of batteries are going to be for the V2G – vehicle to grid –
