Table: Saving Energy with Superconductors
Roughly 8% of all electricity in the U.S. goes up in smoke--actually, heat--thanks to the resistivity of copper and aluminum wires. Trimming those losses with superconducting materials could produce huge benefits.
APPLICATION NET SAVINGS* ANNUAL WORTH Urban power cables and transformers 0.2-2% $4 bil. Large motors** (over 1,000 hp) 1-2% 2 bil. Power generators 0.5-1% 2 bil.
* After cooling costs, and assuming nationwide adoption ** These motors use about 30% of all electricity in the U.S.
