You are choosing to completely ignore reality. Many entire countries are moving to entirely renewable. My home and EVs are powered almost entirely by our home solar and batteries, and I live in Michigan.
We would be powered 100% by solar but our laws here allow the utility to limit the size of our system.
Sorry but you're stuck in the past and have failed to update with new information. Pull up a graph of renewables levelized cost of electricity, and lithium ion grid scale storage cost per kWh, over the last 20 years, and note change. Renewables are contributing massively today, look at ERCOT or CAISO today. CAISO has about 15 GWh of storage deployed already and will deploy more soon. It's not theoretical. And this contribution of renewable to the grid will grow exponentially as costs keep declining and funding keeps increasing. You were absolutely correct 20 years ago where renewables used to be more expensive and grid scale storage didn't exist, but costs have changed.
