Randahl FinkWhile Trump is holding rallies claiming that wind turbines do not work, I am looking at the realtime view of Danish power generation…
Total electricity consumption: 5817 MW
Total electricity production from wind: 6436 MW
Kevin RussellIs 600 MW exported?
Rad und TatGreat. I hope that batteries soon provide another use for surplus.
@kevinrns @randahl Batteries are great, but they are second best to using the electricity when it is available. Load balancing is key and often overlooked, from dynamic pricing to get people to charge their cars etc during a glut, to ramping up industrial production during predictable hours of cheap energy (eg daytime in summer), there's a huge amount that can be done.
Batteries let solar energy power us 24/7.
People once proudly shared their transister radio playing music anywhere. Imagine. Eight transistors, powerful technology.
Transistors now? Processors now measure in the tens of billions of transistors. 8 to 30,000,000,000
Battery costs are roughly falling 90% every 11 years.
1st image is battery cost decline of 90% to 2010 to 2022, 2nd is a different 11 year 90% decline of lithium battery cost decline 2013 to 2024.
It's still a cost, though. If I run my dishwasher at noon, I pay nothing, thanks to my panels. If I run it in the evening, I need to buy a battery first. The principle can be extrapolated to entire countries.
Yes, we'll need batteries. But intelligent load shifting (e.g. with price incentives) is better because it reduces the number of batteries needed.
Of course. States should be creating the economic stability of batteries on scale.
But my "ignore power outages" LED bulbs show batteries are cheap, growing ludicrously more cheap, and are being added faster than google provides surveillance hooks into the internet.
