==Purpose==
This page is currently incomplete. By finishing it, we can gain insights like:
* How much energy & emissions can be saved by various societal changes:
** [[frugalism|Buying less stuff]] / ending [[planned obsolescence]]
** Driving less ([[walkability]] or using [[public transit]])
** [[food waste|Wasting less food]]
** Eating more [[plant-based]]
** Making vehicles [[EVs|electric]]
* If [[solar]] was the world's main [[energy]] source:
** How many [[solar panels]] would there need to be near ''homes'' vs near ''industries''?
** How much of the electricity needs to be [[baseload|available 24/7]] (requiring [[energy storage]])?
