@the5thColumnist@ottawa.place @avilewis@mstdn.ca The excuse that voters are on X can be countered by the fact that more potential voters are probably on PornHub.

@davidho@mastodon.world GPS did it for the ability to navigate by memory and reckoning. LLMs are going to do same for creative writing and music composing.

@Sanderde This analysis of Ontario dataset puts Ontario renewables in context. They don’t compete with nuclear, but they could complement it.

@Lats The graph. Shows that there will always be need for fossil backup. Unless we rethink our use for solar and wind. Would be 2x better if those electrons were directed at green steel.

@ohir@social.vivaldi.net @randahl@mastodon.social It is worth emphasizing that green steel can use 100% of the solar and wind electrons with zero battery storage. The concept of a virtual wire reduces the grid changes required to almost zero also. Furthermore if one eliminates gas on the grid by overbuilding baseload nuclear the CO2 savings can be amplified by 10 fold. It just requires a mindset change with very little technological change.

@ohir@social.vivaldi.net @randahl@mastodon.social Lead acid batteries have recommended depth of discharge of 50% lest you significantly lower life. This would mean you’d need 6TWh to be able to discharge to depth of 3TWh.

@ohir@social.vivaldi.net @randahl@mastodon.social Lead acid batteries have a self discharge rate of ~5%/month so they would require even more TWh to accomplish a single 3TWh full discharge per year as indicated by the German dataset.

@ohir@social.vivaldi.net @randahl@mastodon.social That 3TWh has essentially only one full discharge cycle per year. At $100/kWh that battery costs $100b for 16.5GW or $6b/GW. From a climate perspective there is a far better use for that wind and solar power than dumping onto a JIT grid. It is called green steel.

@ohir@social.vivaldi.net @randahl@mastodon.social Solar + wind isn’t the answer in Germany or Netherlands according to simple analysis of real-time datasets

@randahl@mastodon.social The real problem is that wind turbines are not a substitute for fossil energy.

@Paulatics@mstdn.ca Friendica and Pixelfed are great substitutes.
