A transition to “clean energy”
will be incredibly dirty,
and most likely not feasable.
A 2017 World Bank report
estimated the increase of
material extraction
to build enough solar and
wind utilities to produce
7 terawatts of electricity
per year by 2050.

That amount of electricity
would power about
half of the global economy.
Doubling World Bank numbers
would estimate the materials
needed for 100% wind and
solar electricity by 2050:
34 million metric tons of copper,
40 million tons of lead,
50 million tons of zinc,
162 million tons of aluminum,
4.8 billion tons of iron.
For neodymium,
used for
wind turbines:
Extraction will need
to rise by nearly
35% over current levels,
with a worst case
estimate of doubling.
For silver,
critical to
solar panels.
Extraction will go up 38%,
with a worst case estimate
of doubling.
Indium, essential to
solar technology,
extraction will
more than triple
with a worst case
estimate of +920%.
Batteries for nights,
and periods of no winds,
will need 40 million tons
of lithium, up +2,700%
over current levels
of extraction.
That’s just for electricity.
What about the world’s
projected fleet of 2 billion
vehicles?
Global annual extraction
of neodymium and dysprosium
will go up by another 70%,
annual copper extraction
will need to more than double,
and cobalt will need to increase
by a factor of almost four—
all from now to 2050.
Mining is one of the biggest
single drivers of deforestation,
ecosystem collapse, and
biodiversity loss around the world.
Examples:
SILVER:
Mexico's Peñasquito mine
is one of the biggest silver mines
in the world.
It's a 40 square mile open pit mine.
It's flanked by two mile long
waste dumps, and a tailings dam
full of toxic sludge held back
by a wall that’s 7 miles around
and as high as a 50-story
skyscraper.
For 100% renewables by 2050,
we need 130 more mines
matching Peñasquito's output,
just for silver.
LITHIUM:
It takes 500,000 gallons
of water to produce
a single ton of lithium.
In the Andes, where most
of the world’s lithium is located,
mining companies are burning
through the water tables
and leaving farmers with
nothing to irrigate their crops.
That's just to power the
existing global economy.
Most of the key materials
for the energy transition
are located south of the
equator.
The transition to clean energy
by 2050 would be much MORE
destructive to the environment
than continued fossil fuel use.
