Eye of a Needle

GND is a narrative to which numerous academic institutions and researchers support or conform obediently, bat is little more than a disastrous shared illusion.

Superexponential growth
200y ago start FF industrial age
Today population 8x
More than half land surface modified for agriculture
Conseguent ecosystems displacement
Biomass today: 60% livestock, 36% human, 4% wild species combined
Athmospheric CO2 doubled in 220y

We use the capacity (bio-productive and waste-assimilative) of 1.75 EEs.

Problems with GND 💸

Fatal weaknesses in society’s dominant aspirational pathway for combating CC. Life after fossil fuels will closely resemble life before fossil fuels.

Monroe’s law is irrelevant to the physics of energy systems.

Every RE is subsidized by ⛽
Metal and materials mining
Material transprot
Manufacturing use high temperatures
Transport finished products to installation sites
Erection on site
Deconstructed and transported to landfills or recycling

Photovoltaic PV ☀️

Manufacturing 🏭
Temperatures 2000°C
Waste 2800t of water, 1.4t of toxic substances for 1MW of SP
Emission 8.6t of which 95% are 1000x CO2 GHG
Films made of genotoxin Cadmium
Performance 📶
Efficency rate 15-20%
Shockley-Queisser theoretical limit is 33%
Loosing 50% efficiency with time
Lifespan 20-30y
Inverters replace 5-8y
DSP cumulative EOL waste > all e-waste
EROEI < 1.8:1
Storage 🔋
Lifespan 5-15y
US consume 563x his existing storage capacity
1y Gigafactory Nevada production store 3min US demand
1battery kg need 50-100kg of ore
Heavy duty truck and cranes can’t use batteries

Wind Power 🌬️

Turbines
Betz limit on wind turbine efficiency is 60%
Latest PMSGs use rare Nd, Pr, Dy, Tb
Lot of steel (1700°C) and 1.85t of CO2 emission for steel ton
Rare earth metal mined and radioactive waste ratio is 1:1
Rare earth metal processing for turbines generates same radioactive waste than nuclear
1000t of concrete and rebar to fix tower
Blades are unrecyclable
EROEI < 3:1

Hydropower 💦

Dams impacts
Water flow
Water quality
Sediments and nutrients transport
Fish and widlife habitats
Migration of aquatic species
Recreational opportunities
Slow, broaden and warming of rivers
Lack of environmental standard
Repairs needed

Minerals 🪨

Extraction
IEA “net zero” requirements are 6x resources used today
This metal production require FF combustion over 15y equal to that used from the SOH
10% energy consumption is extraction and processing, prone to rise
RE technologies brings ecological cost and social damage to GS

Technological Carbon Sequestration TCS 🥷

CCS and DAC
Continued use of FF
$600 Bn to sequester 1Gt
Biggest planned plant sequester 1Mt/y
Humanity emit >40Gt/y

Liquid fuels 🛢️

: Account for 80% of non-electric consumption
CEs hits the Carnot efficiency limit
Urban civilization is dependent on highway transportation for essential supplies

One Earth Living 🌏

Renowables
RE technologies are not renowable and impossible to implement with no FFs
Renowable enrgy sources are wood, mechanical wind/water, passive solar
Human labor: active life, nature, less material, more mind and spirit
Animal labor: required today >150 million horses and ranges
Consumption
The ecological imperative is to achieve one-Earth living
62% Energy is wasted in inefficiency
Pre capita energy consumption increased 9x in 170y
More then 99% of labor is done by FFs
Population
One billion can thrive in OEL
Real number depend on living standard
Global one-child fertility standard
Reshape socio-economics
GFN state 75% overshoot
FF budget allocated on essentials as agriculture and bulk transport
De-commisionFF infrastructure and supply chain with renowable
Workers retraining
Social planning for allocation and distribuition
Planned migration from dense centers and coastlines
Large scale ecosystem restoration
Unrelenting pressure on politicians

Important achievements arise from the pursuit of the seemingly impossible
