Silicon - Energy Eduion

Silicon is found in nature in the form of silicon dioxide (like some types of sand and many rocks). The extraction of silicon from silicon dioxide is extremely energy intensive; it requires 1000-1500 megajoules of primary energy per kilogram to process high-grade silicon for computer chips or solar panels.

Silica | Minerals Eduion Coalition

Silica Also called silica sand or quartz sand, silica is silicon dioxide (SiO 2).Silicon compounds are the most significant component of the Earth’s crust. Since sand is plentiful, easy to mine and relatively easy to process, it is the primary ore source of silicon.
