Answer 1

Easiest example: an iPhone 13 Pro Max battery contains ~16 Watt-hours. That’s enough energy to lift a 1000kg (one metric ton) block of concrete to a height of 5 meters (16.4 feet).

So you’ll have to do that every morning to charge your phone. And that’s just your phone!

Same amount of energy to use a microwave for 60 seconds.

Same amount of energy to use an electric stove burner for 30 seconds.

You’d die of exhaustion. 🙂
