THE BALANCING ACT TOWARD A Green Energy Future with Lithium

- BY JIM BRACE THOMPSON

Obtaining resources for sustainabl­e lithium-based electric car batteries to power a “green energy” future does not come without cost. A feature article in Time magazine explores how lithium extraction in sensitive desert regions of Argentina (which accounts for 21 percent of world lithium reserves) could present a new gold rush—or yet another environmen­tal disaster.

Remote regions across several countries within the South American high Andes would seem to be empty and sparse of anything worthwhile, but in these highand-dry environs, companies have found lithium, an element now essential for a green energy future. Extracting this mineral, however, involves pumping and using signi€cant quantities of precious groundwate­r from one of the driest places on Earth. Some companies, like Lilac Solutions, claim to have developed technologi­es to extract lithium without otherwise unnecessar­ily disrupting or contaminat­ing undergroun­d water supplies in this sensitive desert region. But have they? Other companies making such claims have le‡ Indigenous Andean villages in ruins. ‰e Time article describes it as “neocolonia­lism dressed up as a green revolution.” While we all may wish for net carbon neutrality, may we consider the not-so-pretty costs of reaching this goal.
