Nanotechnology could turn out to be the most important technological development for advancing energy technolgies in well over one hundred years. Nanotechnology, which means building technology on the molecular or nano (billionths) scale, has already started to impact solar energy and battery storage technology. Nanotechnology might someday allow for far more powerful, more efficient and less expensive solar and battery storage technology. Nanotechnology is a rather young field, only gaining acceptance in the late 1990s, so the potential for future advancements is very high in coming years.
