2024-09-17 Here’s How EVs Could Actually Make The Grid More Resilient

Here’s how the EVS could actually make the US electric grid more resilient.  It’s a good article.  It uses the term VGI – vehicle grid integration. https://www.emergingtechbrew.com/stories/2024/09/11/how-evs-can-make-the-us-electric-grid-more-resilient

2024-08-13 Debunking Myths: “10 Reasons All Electric Is A Bad Idea”

Each point of the link is debunked. Top 10 Reasons All-Electric Is a Bad Idea #1.)  “”Electric systems are awfully wasteful.”” This assumes that all electrical power is generated by thermal power plants.  Yes, 2/3 of the energy used to heat the steam goes to waste and only one third gets to produce electricity. But

2024-05-12 Giant Batteries Are Transforming the Way the U.S. Uses Electricity

This link to the article is supposed to be free, and *not* behind a paywall.  This well-researched article is a good article, with some statements that are disputable.  One example is that they state that lithium batteries are flammable.  The LFP cells now used in battery storage systems are low to not flammable.  There are

2024-05-07 Lithium-free Sodium Batteries Enter Production

Natron enters low volume production.  The article says 70 Wh/kg, less than half of lithium.  “”…advantages such as faster cycling, longer lifespan and safer, non-flammable end use have made sodium-ion an attractive alternative…”” https://newatlas.com/energy/natron-sodium-ion-battery-production-startt/

2024-04-30 IEA “Batteries And Secure Energy Transitions” Report

Quote: “”The IEA’s “Batteries and Secure Energy Transitions” report finds that capital costs for battery storage systems are projected to fall by up to 40 percent by 2030. This significant cost reduction will make combining solar and wind with battery storage more affordable than building new coal or gas power plants in many parts of

2024-04-28 US Plan To Upgrade 100k Miles Of Transmission Lines In 5 Years

Short article about deployment of enhancements such as high performance conductors.  Quote: “”…and up to $331 million from the Bipartisan Infrastructure Law for a new 285-mile transmission line that will carry more than 2 gigawatts (GW) of transmission capacity from Idaho to Nevada.”” The US just came up with a plan to upgrade 100k miles

2024-04-16 California 100% Renewables for 30 Days!

That’s great news! One thing I just remembered is that the nuclear power plants (Diablo Canyon, Palo Verde) usually shut down for maintenance in the spring when demand is lowest.  Otherwise they normally run 24/7 and there wouldn’t be any time during the day when it would be 100% renewables. https://electrek.co/2024/04/15/renewables-met-100-percent-california-energy-demand-30-days/

2024-04-10 IOUs, Going Off Grid

The transmission pylons are a few million dollars a mile, and the undersea cables are even more expensive. And the undersea cables are more difficult to maintain, as is anything in a marine environment. So the cheap SOBs in the utilities typically choose the lower cost towers. As for the US West Coast, rooftop solar

2024-04-07 Esbjerg Changes To Heat Pump City Heating System

The city of Esbjerg, Denmark is replacing its coal fired city heating system with an amazing giant heat pump, biomass boilers and waste burning boilers.  The refrigerant is CO2.  Read the description. This is a long 43 minutes but is very comprehensive and interesting.  The cost is about 40 million Euros. 

2024-04-05 Graphic Shows Renewables Percent Of Total Electric Generation 2000 to 2023

This is a very good graphic of the percent of total electricity renewables have grown to since 2000.  Notice the bulging in April and September, and flattening during the summer.  These are caused by the changes in demand during the hot weather.  We need this to be 100% ASAP in order to prevent climate disaster!
