2024-12-21 Solar Finally Goes Exponential

Sam (the Electric Viking) tells us about a Renewables futurist and how China is installing renewables that are the equivalent of five nuclear power plants *a week*!!  China has surpassed 1 Terawatt of solar capacity in 2024.  Global installed solar capacity has hit two terawatts!  It took 68 years to reach 1 Terawatt Solar capacity,

2024-11-11 Ultra High Voltage Workers In China

Notice the second worker clamping the conductor into that hexagonal ring.  Wow!  Each conductor is the size of his wrist!  But it’s even more amazing there are *six* of them in each bundle!  There are 3 or 6 of the bundles, and each bundle is held up by hugh insulators.  Each bundle of 6 conductors

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/
