Why Every Power Supply in Your House Says “100–240V” (A Story About Japan)

I was getting ready for an upcoming trip to Europe and picked up my laptop's power brick to check the voltage. The label said 100 to 240V, which was fine. But then I noticed something odd: who runs on 100 volts? The answer turned out to be one of the best pieces of accidental history I've ever stumbled into.

At Intersolar, companies including Huawei and Siemens Energy are focusing on how to keep electricity grids stable when large spinning generators are disappearing.

The answer increasingly being proposed is grid-forming technology, with systems that can actively establish and regulate voltage and frequency.

So what is this technology and why is it a hot topic?

American lawmakers in all the states currently considering legalising #pluginpv should read this study!

#pluginsolar is safe and can help consumers to safe money, bridge power outages and help to transform the the grid towards green power.

Why Building AI Data Centres Isn’t Working Anymore

YouTube

"As these data centers get bigger and consume more energy, the grid is not designed to withstand the loss of 1,500-megawatt data centers,"

"What it tells us is that the behavior of data centers has the potential to cause cascading power outages for an entire region"
