Can Solar Rooftops Power the World?

Undisciplined

I'm using a solar rooftop for my hould energy needs but I'm kinda aware that this isn't costing me less financially. Batteries and other required stuff for solar plant are very expensive here and they also pose risk to environment in the same way.

> Lithium-ion battery packs are made with materials that are expensive, and in some cases, toxic and flammable. Primary materials include lithium, nickel, cobalt, and copper. The mining of these rare materials, their manufacturing processes, and their eventual disposal all pose very real environmental challenges.
