For small electronics, little lithium accus work just fine. Here, I got a cheap 10000 mAh accu from a supermarket = 10 Ah at 3.3 V (even though its nominal output is 5V, they're rated at internal voltage to scam customers) so 33Wh, converting from hours to seconds we get 336060 Wsec = 118800 J. That would be equivalent to raising 1 cubic meter of water about 118800 / 9.8 / 1000 = 12.1 meters. And that is why pumped-storage isn't used at small scale.

Fertilizer became a critical bottleneck during the height of recent inflation. You can still buy it, sure. You'd need a lot of chickens to fertilize with their poop alone...
