> the impact storage (both stationary and in the form of EVs) will have in the future. Have you ever heard the expression "hope is not a plan"?

I'm basing this on the huge increase in battery production. From https://www.iea.org/data-and-statistics/charts/annual-grid-scale-battery-storage-additions-2017-2022 https://www.iea.org/data-and-statistics/charts/annual-grid-s...: * Annual grid-scale battery storage additions went from 0.76 GW in 2016 to 11.21 GW in 2022. I couldn't find the GWh figures, but this is a fast ramp up. * "In September 2022, India released its draft National Electricity Plan, setting out ambitious targets for the development of battery energy storage, with an estimated capacity of between 51 to 84 GW installed by 2031-32." * "In December 2022, the Australian Renewable Energy Agency...announced funding support for a total of 2 GW/4.2 GWh of grid-scale storage capacity, equipped with grid-forming inverters to provide essential system services that are currently supplied by thermal power plants." From https://www.iea.org/reports/global-ev-outlook-2023/executive-summary https://www.iea.org/reports/global-ev-outlook-2023/executive...: * "Automotive lithium-ion (Li-ion) battery demand increased by about 65% to 550 GWh in 2022, from about 330 GWh in 2021" * "August 2022 and March 2023, major EV and battery makers announced cumulative post-IRA investments of at least USD 52 billion in North American EV supply chains – of which 50% is for battery manufacturing, and about 20% each for battery components and EV manufacturing." These pages also list the challenges faced, so I'm not assuming it's a smooth road ahead. However, the trend is clear. Hopefully, technological improvements will continue and drive down costs further (I have no knowledge if this will happen). I hope there's improvements in nuclear technology that allow for a faster, cheaper nuclear rollout and belief it has it's place. But to return to original comment I replied that states "we need something to replace coal...that thing can...only be nuclear at this point" dismisses the increases in investment and production of battery storage.
