The Limits of Clean Energy |
If the world isn’t careful, renewable energy could become as destructive as fossil fuels.
new problem is beginning to emerge that warrants our attention. Some proponents of the Green New Deal seem to believe that it will pave the way to a utopia of “green growth.” Once we trade dirty fossil fuels for clean energy, there’s no reason we can’t keep expanding the economy forever.
This narrative may seem reasonable enough at first glance, but there are good reasons to think twice about it. One of them has to do with clean energy itself.
The transition to renewables is going to require a dramatic increase in the extraction of metals and rare-earth minerals, with real ecological and social costs.
In some cases, the transition to renewables will require a massive increase over existing levels of extraction. For neodymium—an essential element in wind turbines—extraction will need to rise by nearly 35 percent over current levels. Higher-end estimates reported by the World Bank suggest it could double.
The same is true of silver, which is critical to solar panels. Silver extraction will go up 38 percent and perhaps as much as 105 percent. Demand for indium, also essential to solar technology, will more than triple and could end up skyrocketing by 920 percent.
If we don’t take precautions, clean energy firms could become as destructive as fossil fuel companies—buying off politicians, trashing ecosystems, lobbying against environmental regulations, even assassinating community leaders who stand in their way.
None of this is to say that we shouldn’t pursue a rapid transition to renewable energy. We absolutely must and urgently. But if we’re after a greener, more sustainable economy, we need to disabuse ourselves of the fantasy that we can carry on growing energy demand at existing rates.
We need a rapid transition to renewables, yes—but scientists warn that we can’t keep growing energy use at existing rates. No energy is innocent. The only truly clean energy is less energy.
