The transition to clean energy by 2050 would be much MORE destructive to the environment than continued fossil fuel use

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

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.
