Why solar energy is bad?
Solar panels consist of photovoltaic (PV) cells that convert sunlight into electricity. When these panels enter landfills, valuable resources go to waste. And because solar panels contain toxic materials such as lead that can be squeezed out during decomposition, landfilling also creates new environmental hazards.
