==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]])? | |||
