Like I said in that post we are seeing a massive change in battery technology. Right now we have less than 10 gigawatts of battery storage capacity for solar in the US. Within 3 years, there is 30 gigawatts planned to be built or a quadrupling in the available storage. That number was around 2 gigawatts in 2020. So it's going from 2 to 30 gigawatts in 5 years. But yeah, keep telling me how it's not a cost effective. It's weird how many of these companies are wasting money on solar and battery tech when they can listen to you and save billions.
