17. Hybrid Cars’ Batteries
Hybrid cars are celebrated for reducing tailpipe emissions, but their batteries come at a steep environmental price. These batteries rely on rare earth metals like lithium and cobalt, the mining of which is notoriously polluting and energy-intensive. The extraction process often devastates local ecosystems and consumes vast resources. Furthermore, safe disposal and effective recycling of spent batteries remain major challenges, creating a new wave of environmental hazards. As Reuters reports, the hidden costs of hybrid technology are often overlooked in the push for greener transport.
