The thing about energy from the Sun is that even though we use it, the Sun doesn鈥檛 get used up.
Every other energy source we pull from gets consumed when we use it. Coal, oil, gas, uranium - once it鈥檚 gone, it鈥檚 gone.
Sunlight keeps coming on the Sun鈥檚 own schedule no matter how much we harvest.
We can take as much as we like with zero effect on the source.
Pretty unique when you think about it. 馃
