As American policymakers seek to encourage the expansion of renewable energy sources, researchers expressed concern that outdated solar panels, wind turbines, and electric car batteries will clog landfills with dangerous materials.
A Harvard Business Review report explained that Americans are turning to solar power due to federal tax benefits and rising solar panel efficiency. One side effect, however, is that Americans will have reason to toss their solar panels for updated models — a reality that will clog landfills with hazardous waste such as cadmium and lead.
