What’s bad about solar energy?

Solar panels are composed of photovoltaic (PV) cells that convert sunlight to electricity. When these panels enter landfills, valuable resources go to waste. And because solar panels contain toxic materials like lead that can leach out as they break down, landfilling also creates new environmental hazards.

What are the negative effects of solar energy?

The environmental impacts associated with solar power are land and water use and pollution, habitat loss, and use of highly hazardous materials in the manufacturing process.
