Yes, to produce enough electricity that everyone can have their tesla/candela is impossible because we are running out of cheap dead trees.

Electricity is not an energy source.

EROEI is already below 10 on the dead trees we use today (down from 100 a century ago, that's 10x or 1000% down).

And you need dead-trees to build nuclear and hydro. Solar and wind are useless.

A weight ratio of equal between transport (including energy storage) and transported is the only solution.

Personally I find the half weight of lithium to not compensate for the complexity/price, so I recommend lead-acid.

Not fully sure what dead trees have to do with anything?

Can you expand on what you mean by dead-trees are needed for nuclear and hydro?

And can you expand on what you mean by solar and wind are useless?

Based on what I've seen EROEI seems to be for wind, solar not so much due to product costs, but wind seems to be above the 7 threshold.

Dead trees = coal, oil and gas.

Solar and wind are not something you can decide when you want it and the EROEI is only ok if you subvention the manufacturing and/or grid with dead-trees, when you look at it from a system perspective they are utterly useless.

The numbers only look good through the debt lens.

Both solar and wind have very short lifespans.
