Solar now being the cheapest energy source made its rounds on Lemmy some weeks ago, if I remember correctly. I just found this graphic and felt it was worth sharing independently.

I want a battery in my house big enough for me to lose power for 2 days and still cook with electric stove and have hot water from water heater.
That is my dream for every house. To be able to have a stable power well from some kind of battery fed by a solar + grid sharing. To be able to offer extra power to a neighbor if they need it for a project or a party or help however.
I don't want to be energy isolated from the grid. I want to be energy insulated and be of the grid.
Hydrogen is the answer for that, cost about 100k today hopefully those cost will decline fast
