The entire point of hybrid batteries and new energy technology is to be environmentally friendly and sustainable. While these new products don't have a zero percent pollution footprint, they are markedly better than the solutions that came before them. Through constant research, development and refinement, we'll continue to produce better alternative energy hybrid batteries that don't hurt he planet.
Hybrid batteries are not environmentally friendly. They often contain lead and other dangerous minerals that contaminate the water supply when they are disposed of. Also, the mining of rare Earth minerals which are needed for the batteries is very bad for the environment. Companies should develop cleaner batteries for hybrid cars.
