Coal Power Is Replaced by Renewables, Batteries, and Modern Electronics

Other - Blog post, 2025

-Gas was a bridge, not the destination. Initially, natural gas replaced coal. But in the last decade, wind and solar have increasingly replaced both coal and gas — thanks to their low costs.
-Batteries provide stability and flexibility Batteries and advanced inverters provide stability in a time scale from milli-seconds to days, while allowing solar and wind energy to power the grid even when the sun isn’t shining and the wind isn’t blowing — displacing gas in critical peak periods.
-Modern Grids No Longer Depend on Thermal Power Electronic controls, batteries, and advanced grid devices (like inverters and Statcom, VAR compensators) can now handle frequency control, voltage stability, black start, and reactive power — all without relying on large spinning generators.
-Electro-chemicals and -fuels, will provide for replacement of fossil fuels and long term stability of electricity systems.
