Earlier I made a bold statement that there’s no such thing as a sustainable energy source. Lat’s take say solar panels:
- No air pollution
- No carbon footprint
- Minimal maintenance
- Minimal environmental impact
A perfect source of green energy. Well, not quite. Factor in the production of cadmium, gallium, germanium, indium, selenium and tellurium used in the manufacture of solar panels; factor in the labor, energy, transportation and installation costs; factor in the life span, decommissioning, dismantling, disposing and recycling costs and you’ve got yourself one of the dirtiest sources of energy.
