Hash Tag Fact Check
- Lead acid is 99% recycled today. Lithium ion is hardly recycled - [1]
- Lithium batteries rely on strategic resources and are not great for the environment - [2]
- 'Thus, while the 99% recycling statistic is important, it may understate the potential for lead contamination via this process. However, the situation would definitely be much worse if these batteries were being landfilled, as a single lead acid battery in a landfill has the potential to contaminate a large area. ' - [3]

Lithium vs Lead Acid Life
- If low depth of discharge - only 20% - lead acid lasts a long time. 7000 cycles, or 20 years. [5]
Generation Costs
- The renewable revolution has been won - [6]. Polsky is a wind power billionaire, says '“If you’re just making money, you can only go so far,’’ he says. “When you have a mission, a conviction, you perform on a completely different level. You believe so strongly, you don’t take no for an answer.”'
Conclusions
- Use lead acid at low depth of discharge for the most affordable option
- Lithium will run out by 2100 if no recucling occurs. But it's recyclable - so recycling will increase. [7]
- The nonscarce solution from the distributed economy perspective is Solar Hydrogen.
