5. High-Temperature Superconductivity (HTS) is Pivotal to US Energy Sustainability  10% of electricity generated in the US each year (300 million kilowatt hours) is lost due to resistance of copper and aluminum wire  Superconductors, which have nearly zero resistance, can make most of that lost energy available with no additional fossil fuel use or generating capacity The energy lost to electrical system inefficiencies could supply the combined energy needs of California, Oregon, Arizona, and New Mexico  Superconducting Magnetic Energy Storage (SMES) systems will improve infrastructure reliability by protecting against grid fluctuations

6. Accelerated HTS Technology Development will Impact the US Significantly  Save $16B annually in US energy costs  $11B in transmission losses  Rejuvenate the US power equipment industry  $200B annual sales worldwide of HTS power equipment by 2020  Strengthen the reliability of the US electricity infrastructure  Create 150,000+ new high-technology domestic jobs  Improve medical, communications, and electronic equipment  Improve systems for national security  Eliminate hazardous materials from electrical systems

7. Superpowering the Electric Grid High Temperature Superconductors (HTS) –no electrical resistance (cooled with liq N2) –1000 times current carrying capacity of copper –more powerful, efficient, smaller, lighter –Increased Energy Infrastructure Security Compliments of ASC VG19
