My reply to FB comment. Jeffery D. Elliott Said, “… the demand for electricity [for charging] will require more power plants and that will drive the cost up. You don’t hear much about that.” The reason why you don’t ‘hear much about that’ is because it’s *not true*. The amount of power wasted by the

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

Up until lately, Big Oil has been paying token lip service to climate change; it has been business as usual with little action taken. But now shareholders are taking action with their votes against Big Oil’s complacency and greenwashing. But the court ruling against Shell is really the most damning. Shell must make its actions

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

The Court in the Hague has ordered Royal Dutch Shell to cut carbon emissions by 45% by 2030. The court accused them of violating Dutch law and European human rights. The landmark case was brought by Friends of the Earth and more than 17,000 co-plaintiffs. https://amp.theguardian.com/business/2021/may/26/court-orders-royal-dutch-shell-to-cut-carbon-emissions-by-45-by-2030 This news made it to all the major mainstream

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

The halting of climate change requires that fossil fuels be replaced; the CO2 must be stopped from entering the atmosphere. The consensus is to build wind and solar farms to generate electricity instead of using fossil fuels. Since renewables are intermittent, there must be some way to store and supply electricity when renewables are not
