All this liberal propaganda sounds great until you begin to wonder:

There are several video interviews with the authors if the spoken word is more approachable. Here is one by Max Wilbert.

The book gets a little redundant as it works through the feel good technologies like wind and solar, delving into the true environmental
costs that are out of sight of the people driving their Teslas. Or
polluting the atmosphere burning their Teslas to virtue signal.
Before someone says "Oh a bunch of climate denying Trumptards", no, these
are radical environmentalists who would like to tear the whole industrial culture down. That doesn't stop them from seeing the truth.
I'm not political. I'm scientific. The liberals claim of "batteries having
no tailpipes" only works for people who are ignorant of basic principles.
For the liberals to outlaw gas lawn mowers, under penalty of force, is my problem with the liberals. Not only do the liberals take away choice, but
they are "science deniers" in a way that I can easily prove given the math.
1. A common recommendation is to keep the Depth of Discharge below 80%.
This means only using 80% of the battery's capacity before recharging.
2. Given that, a lawn mower 60V, 11Ah battery has a usable capacity of:
11 Ah * 0.80 = 8.8 Ah
3. Usable battery energy:
60V * 8.8 Ah = 528 Wh = 0.528 kWh
4. Usable energy delivered from the wall plug to the lawn mower
from the battery 0.528kWh * 42.5% = .2244Kwh
5. Gasoline energy needed to equal usable battery energy:
0.2244 kWh / 0.20 = 1.122 kWh
6. Equivalent gasoline volume:
1.122 kWh / 33.3 kWh/gallon = 0.0337 gallons
7. Equivalent gasoline volume in ounces:
0.0337 gallons * 128 ounces/gallon = 4.32 ounces
Therefore, with an 80% Depth of Discharge (DoD), one 60V, 11Ah Lithium-ion battery cycle is equivalent to approximately 4.32 ounces of gasoline.
I ran separate calculations for how many battery cycles before a typical lawnmower battery needs to be recycled, which equaled 6-1/2 gallons of gas.
So we have to compare the pollution, from cradle to grave, of one 60V, 11Ah Lithium-Ion battery to that of 6-1/2 gallons of gasoline.
While it's difficult to assess "equivalent pollution" when one is from
mining and disposing of toxic chemicals and the other is extracting &
burning of petrochemicals, the fact is that lithium batteries pollute too.
However, my argument about the liberals being 'science deniers' is that
they mandated a technology claiming it doesn't pollute - and yet - it does.
The liberals in California are "science deniers" which is what I decry.
